So I got a Samsung 32GB class 10 MicroSD card off eBay for my soon to ship AT&T Samsung Galaxy S3 and I ran some tests on it and got some weird results and I'm wondering if I got an el-fako. It was a bulk packaged one (ie just in an adapter case holder).
I ran h2testw and got results lower than I was expecting (like 15 read/6 write) but that didn't bother me too much. But then I tried to run CrystalDiskMark; I didn't realize that selecting 5 made it run the tests 5 times and it was taking forever, so I left it running when I went to bed. When I woke up it was frozen on Random Write 4KB (QD=32) [1/5] hitting stop did nothing and I couldn't close the program or even end the process in task manager. When I went into the disk in my windows explorer it froze windows explorer and then I couldn't do anything really involving the SD card. I even had to cold power down the system since attempting to shut down within the OS did nothing.
Now today running CrystalDiskMark it ran the first 7 tests fairly quickly on 1 iteration and then it's again stuck on the last test Random Write 4KB (QD=32) [1/1]. Or at least it's been doing that test for like a half hour with no change and as mentioned overnight it didn't get past it so I doubt waiting will do anything for me. A screenshot of the results so far are attached.
Now having said that, I am using the built-in 7in1 card reader in a 4 year old dell Vostro 1700 so it wouldn't surprise me if the reader couldn't handle the top speeds of the card or even if it freezing up was the fault of the reader but I am concerned. Anyone have any thoughts?
Ebay fake Samsung SD cards
I had the same issue. 15 R/ 6 W, when class 10 clearly should be constant speeds of 24 Read and 13 Write. Brought from ebay seller moe_122 for £19.99 32GB Class 10 Samsung Micro SD.
I tried this both on my laptop card reader and my PC, using both the SD card adapter and a standalone USB Micro SD card reader.
I then checked out images of some available from Amazon and they are clearly different. Genuine mSD shown on Amazon had writing on back, whereas the one I'd received was blank.
I have today, emailed them requesting a replacement, they instead offered a full refund. the only thing is now I have the S3 but no micro SD card, and I have to post it back to them. They tried to say that I was liable for return postage but I was not having it. In the end I just escalated to ebay resolution center and they begrudging agreed to refunding me the postage.
I just brought one from amazon for £19.99 with free super saver delivery.
Thank me if you found this useful.
This is why you never buy Sd-Cards from ebay!!
Try Amazon, I'd recommend Sandisk also

Yeah mine has writing on the back and it matches every picture I've seen so far. I know that doesn't really indicate anything re: fake/bad but it's at least not an obvious fake.
This will be my first time ever having an issue with an eBay purchase if it is one and the buyer has 99.99% positive on like 80k deals so I'm sure worst case I get a replacement or a refund. I'm not too worried about it; it's just annoying if in fact it is a bad card/fake. I would have bought from Amazon but at the time I ordered they didn't have any good deals and the eBay price was like $10-$15 cheaper. Of course since then there have been a couple deals at the same or better pricing. If it turns out this one is going back I'll probably try and be patient and pick up a 64gb sandisk if they drop to ~$50-$60 again soon.
Hm...
Argh... as a noob i cannot yet post link to the photo of mSD card on amazon.
I too have had positive experiences with ebay so far, but when it comes to things like this, I guess it is better to go with a reputable seller like Amazon.
Go into your phone shop dealer and see what cards they sell there.

Hey Erikk, I am having the same exact problem as you, I am using the card reader in my new laptop and my card is benching much higher as it should be but when I am getting to the same test it gets frozen on Random Write 4KB (QD=32) [1/5] and nothing happens I can't end process, I have to cold power down like you as well. I know for a fact the microSD card I got is not a fake because I compared with other real samsung 32gb mircosd cards. I got mine at a MicroCenter. I don't know what to do at this point because the card is fantastic as far as speed is concerned it just gets stuck at that part...
Appreciate help from anyone that knows a possible solution, returning it may be the only option but I have a hard time believing the card it self is defective.
There are so many fake cards on eBay it's not even funny. I got burned once and will never buy there again. I'd rather pay a little more at my local store, at least then I have the peace of mind of being covered by consumer protection laws.

UPDATE: Booting into safe mode did the trick, I no longer get frozen on Random Write 4KB (QD=32) [1/5] ALSO my speeds seem to have improved some more as well. lol :victory: No defect with the card after all, just something was not working well with crystaldiskmark in the normal OS environment.
I just don't get why people spend £500 on the best phone available then go to Ebay to find the cheapest card they can possibly find.

If you want them cheap get them from ebay, but dont blame anyone if you get a fake one, you get what you pay for. It has been said many times, many ebay sellers sell fake micro sd.

Always get a good quality card reader, dont compare the cheap and nasty one's with a branded one, you won't get the same results.

Cos they just spent all their money on a $700 phone....
I went to eBay because it was cheap enough that I really didn't care if I got burned on a fake card (plus with all the paypal/ebay protections the burn would only be the annoyance of disputing the charge). I am now fairly certain it's not a bad or fake card; in the S3 antutu reads it with the correct speeds. I think it was just the 5 year old multi-card reader built into my laptop that was having issues.
So either way, I'm happy now with my card.
I'm normally very careful, but I made the mistake of buying some "Sandisk" SD cards from Ebay.
They looked absolutely perfect, the welded plastic packaging was flawless, yet sadly they turned out to be fake.
A typical scam is to reprogram and rebrand cheaper, smaller capacity, slower or otherwise low quality cards as pass them off as high quality brands.
Often everything seems OK until the card is part-used, when files start to corrupt. Of course, often by the time this becomes apparent, the seller has scarpered.
If the price looks too good to be true, it often really is too good to be true.
Well the seller I bought from has been an ebay member since 99, has 80k+ ratings and 99.9% positive feedback, so hopefully I won't have that happen. But yes SD cards are definitely one of the riskier items to buy off ebay.
Best tool to test SD for fakes is called H2testw. I have bought one fake on eBay, and seller also had 99% positive feedback. I guess people buy 32GB card and never get past the 1GB or 2GB by the time they leave the positive feedback. If you pass the real space everything will be corrupted. So you really never know until you try to get data out of the SD to use it. Try that tool and it will full the SD card and then read it back.

That sounds a really helpful tool, thanks!
I'm sure you are exactly right about the typical Ebay scam.
I watched one seller who had vast amounts of sales and great feedback.
They suddenly flooded the listings with vast numbers of "Kingston" brand cards at silly low prices.
Nothing happened for a while, then suddenly the bad feedback started to roll in on that supplier about corrupt data. Of course, all the cards had been sold. Seller vanished without trace.

Yeah my card passed H2testw. It just came back with speeds I thought were too low for what the card should have been capable of. With the tests I've run with the phone itself I think those slow tests were just indicative of the crap reader my ancient laptop has. So I guess I got lucky in the eBay crapshoot.

you need a good quality external card reader to get upto standard results, kingston and sandisk has the fastest card reader on the market costing approximate USd 35 - USD 45.
card reader built into laptop does what it suppost to do, but at low speed.
Fake or Real
I have downloaded sd tools on my S3 and I'm getting results of 7.2 MB/s write speed, and, 17.6 MB/s read speed.
Is this fake or real?
Okay,
So I had a PNY class 10 for less than a year in my evo 4g, worked flawlessly. Bought a Sprint Siii, formatted my PNY and used it fine for a few months then all of a sudden one day my phone said I had a blank or unsupported SD card and that I had to format it. Of course I lost all my pictures and such. I tried all the programs to recover, tried adapters on the computer, I followed all the suggestions. Then gave up and tried to format it, that didn't even work, seeing that I could not format it... Hey I just thought according to all the smart people (sarcasm) online it must be dead, even though I never had an SD card die on me in any of my other 50 devices that used various SD cards.
So I just felt horrible for buying a budget SD card PNY, I didn't think was that bad, but now knew it was trash since it just died on me less than a year, and back when the EVO was out class 10 16 gig was expensive that was almost 4 years ago.
This time I thought I was not going to skimp on the card, I went straight for SanDisk Ultra 32 GB MicroSDHC Class 10 UHS-1 from Amazon even made sure according to those wonderful lemmings online on posts about this, it was an official SanDisk SD card that I had to cut open.
So Got my new card everything was peachy keen for about a month, and please get the wonderful irony in this, last Friday I bought my mom an Siii from Sprint because they were having a sale for them for $50. I thought to myself I had to upgrade her crappy SD card and I ordered her the same card...It comes I install it in her new Siii and less than an hour later the SD card in my phone says either SD card removed. Insert a new one. or SD card is blank or has unsupported files. So it appears my Siii struck again... I immediately took the SD card out of my mom's phone and told her its better to use the internal storage. Of course all my pictures and things are gone. Over 400 pictures! back up back up you say... okay I have after my last lesson most of them are on my dropbox but still not all of them. YET THIS SHOULD NOT HAPPEN TWICE IN A ROW. I refuse to just believe that "SD cards just die" I call BS maybe once in a while but not like this.
I think there is a problem with this phone and Samsung will never admit it since they sold over 30 million phones and are the envy of Apple, but I was hoping that someone on here could prove it, figure out how to fix the SD cards to recover the information or prevent this, and or take some kind of poll to see how common this is with the Siii I have a feeling this is a known issue to someone/I will not be buying another sd card to use with a phone again. This experience is abhorrent.

I have recently been having an issue with my GN2 photos. I am currently running Beans build 18 rom with a sandisk highspeed 64gb SD card. About every 3rd picture just shows up like 30-80% gray a couple days after being taken. They are fine for a couple days but then go bad. I do have my phone storing them on the SD card which I recently formatted from the phone.
I would greatly prefer to store photos on my SD card as I take a lot of photo's.
Any suggestions?

sometimes the seller will buy in bulk from somebody else and the seller does not even know that there was a problem with the sd card. how it works is the sd card will say it has 32gb on cell phone and on box but really it only has 2-5 gb on them. the last i check ebay for sd cards i could not find a single legit one. you leave the feedback before you realize that it is fake. (this happened to me as well and i was having same issues. but maybe it is something else.....
More specifically, don't use the generic no-name 64GB SD cards with your XZT.
I've been using a generic 8GB SD card with my XTZ since I got it, in fact I've been using the same card for like 2 years now in many different devices and it's never had a hiccup, even after formatting to different file system types.
Recently decided to get a generic 64GB because they're only $10! I bought 2 in case I got a bad one. Popped the cards in the XTZ and it formatted them without problems. I added some comics and music, they played fine, images displayed quick and snappy.
Fast forward to a few days later and there are all sorts of bull**** problems:
•Sometimes the XTZ will stop recognizing the SD card and display the "ready to remove SD card" message. It won't recognize it again until it's reformatted on the PC.
•Music won't play, some files won't display sometimes, and flipping through images is agonizingly slow.
•Available storage will show as very low even if the card is empty or has few things on it. Sometimes the card will show as having 67GB of storage.
•Even if you erase the SD card, if you plug it into a computer it'll show that it still has old files on it.
•Formatting the card to FAT32 or exFAT on the PC fixes the problems, BUT, the problems start happening again whenever you turn off your tablet and turn it back on. Or if you sneeze, it'll get messed up again. Or even when you look at it funny it'll get messed up again.
•At one point an SD card turned into RAW format. How the hell?
•Running Check Disk on the SD cards shows 0 errors, but sometimes it will show hundreds of errors. What the ****?
I'm done with these cards, trying to get a refund now.
Will a 32GB generic card work? Should I just stop being cheap and get a name brand name 32GB? lol

My vote is YES, stop being cheap and by a brand-name SD card; e.g., SanDisk.
I'm using a San Disk class 10 64 gb card on my Tab and XZ2 and it's insanely fast and so far (3 weeks and counting) very reliable.
I once got a cheap 64gb card and it ended up corrupting files every time I exceeded 16gb so yeah, buy a more expensive one and you'll be happy.

Completely agree.
Got a SanDisk Class 10 64gb myself and couldn't be happier. It pays off to buy from a reliable brand.
That's funny, because I originally bought a Sandisk 64G card for my XTZ and had exactly the same problems as described (turned out to be a fairly widespread manufacturing defect). Replaced it with a Samsung 64G card (which was cheaper) and it's been perfect.
I have had no problems at all with both a 64gb and a 128gb card in mine.
Never buy a no-brand ad card. The way these are made is one of the two:
1- When a chip maker builds an sdcard it is subjected to various tests before it is sold. For example if a large number of the memory cells fail the read/write test at hot temperature the part is unusable. Some people somehow get their hands on these rejected parts and repackage (sometimes in packaging that looks very closely like samsung or sandisk) and sell them as good parts. It is then a matter of time before the sdcard fails in your system.
2- This one is even more common. They take a let's say 4GB card and change its firmware and electronically label it as 64GB or whatever they want. You buy it and put it in your device. For the first 4GB your files are saved fine but once you exceed that (which may happen months after the purchase of the card) it will fail.
Conclusion: never buy a no-name sdcard if you want your data to be safe.
As an update, I got a refund from ebay automatically for the card because the seller didn't respond to the dispute. So, yay lol
More importantly, I used this program to format the no-name sd cards and they work fine... for now. Speeds are snappy, I can view comics and music and stuff with no lag, etc.
http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm
Of course, this formats them to the FAT32 file system, so you can't win them all lol. The card still shows up as the proper size in the settings though.
The other card seems to be a fake capacity, I try to put more than 2gb of stuff on it and it just gets erased.
I'm buying a 64GB Samsung Evo card since they're pretty good at $30.
Hello all.
I searched through the forums and couldn't find anything so i thought i would ask here.
huawei says this supports 32gb external sd. i have a 64gb card in there now. i know this may seem like a stupid question, but would it support the 128gb micro sd cards that are out now?
would there be any issues reading the files on it?

It should work. I asked about 64gb cards and while looking online, found Sandisk's compatibility database. If you search on the HAM2, Sandisk indicates that micro SD cards upto 128 GB should work. http://pct1.sandisk.com/Default.aspx I'm looking forward to your post once you are using your new card.

How cheap is that? if just 20-40 dollars, then they are definitely fake sdcard. mean you can format/read/write all fine and show 128gb, but they can't hold 128gb content. Just be careful and test it throughly before store your valuable pictures on it.
Somebody give an update! Does the 128 work or what? lol? Take screenshot to prove it

I browsed eBay recently, and found several 128GB microSD cards.
Unfortunately, there is no single one which is not fake (at least, I have not found one).
Some of them are sooooo obvious fakes, that I'm getting shocked to see people buying them (some buyers simply don't have brains).
For instance, I saw several so called Samsung PRO 128GB microSD cards (with photos showing that this is anything but Samsung card, if you pay attention to these pictures). In fact, Samsung never released 128GB microSD card (they don't have such product on their web-site).
But some idiots do buy this junk (it's probably a 8GB card hacked to report itself as 128GB).
Recently, I bought Samsung EVO 64GB microSD on eBay (well, first 4 purchases from different sellers were a disaster - all were a counterfeit). One of the sellers was even a power seller (621 feedback, and not a single negative/neutral one).
I was a buyer #45 of that card, previous 44 buyers bought this junk card and left a positive feedback (either they don't know how to check an SD card, or they left a positive feedback too soon, and now they can not change it).
I was the first one who reported (tested with H2testw) that this card is a FAKE.
Still ... people continue to buy (they don't get bothered with a "COUNTERFEIT card" negative feedback).
Seriously?! If you don't pay attention to such feedbacks, you deserve to be scammed
Only the fifth one was genuine EVO 64GB microSD card.
95% of all microSD cards (64GB and larger) on eBay are fake. Make sure you know how to test it BEFORE you start to use it.
Added: genuine EVO 64GB microSD card works just fine in my HAM2 (at full capacity, though had to reformat it inside the phone - HAM2 did not like default exFAT format)
well said, especially the software (h2testw) to test the sdcard.
so after reading all that ebay buyer beware did you get a 128gb and stick it in your phone or not? lol
Well heck, it sure looks like someone would know by now. Wonder why they aren't saying.
If I don't change my mind I am ordering one of these phones tomorrow and will order a 128 gb card to go with it. If it doesn't work I am going to be like the other poster who said they ordered one and not post anymore. Just kidding.
there is a significant difference between 32GB and 64GB cards.
First is SDHC, second is SDXC.
Windows does not even want to format SDXC card using FAT32 type (only NTFS or exFAT are allowed).
Not all (old) devices are compatible with SDXC. Thus, they are stuck with SDHC, which is up to 32GB only.
But there is not big difference between 64GB and 128GB cards. Both are SDXC, after all.
Thus, if device can work with 64GB card (full capacity , not just 32GB), it HAS to work with 128GB either.
How can it not?!
PS: sorry, but I'm not going to spend $90 just to play with 128GB card. I have three 64GB SD cards, and it is enough for me. (I had 16GB card in my old HTC phone, and did not find a significant reason to switch to 32GB).

Did you ever receive this 128GB microSD card off eBay seller?
is it a real card? or is it a fake? (you can use h2testw on it, you don't need to write all 128GB on it, 16GB is enough - most fake cards are 8GB or smaller).
meanwhile, I periodically checking responses of other buyers to the same scammer where I bough my fake Samsung 64GB microSD card. He already sold more then 400 those cards, and only 6 people (including me) left a negative feedback telling that this is a pure fake card (one person tested the speed and reported that read/write speed is about 4x slower then claimed - exactly what I measured on my low quality fake card, but still, he left a positive feedback, because he did not bother to use h2testw).
I also saw that one poor fella bought 24 such cards (in a single purchase) couple of days ago. He just wasted his $500+ for that garbage. Unfortunately, eBay hides the information about buyers now. There is no way to contact this buyer and tell him a truth
I got the 128GB card to work in my Ascend Mate 2.
I did however have to format it to FAT32 (It would not recognise NTFS or EXFAT).
I used a program called guiformat.exe
I hope this helps.
There is a program you have to use to format the card into fat32 i believe. I had to use it for my 64gb to be compatible foe my previous note 2

I browsed eBay recently, and found several 128GB microSD cards.
Unfortunately, there is no single one which is not fake (at least, I have not found one).
Some of them are sooooo obvious fakes, that I'm getting shocked to see people buying them (some buyers simply don't have brains).
For instance, I saw several so called Samsung PRO 128GB microSD cards (with photos showing that this is anything but Samsung card, if you pay attention to these pictures). In fact, Samsung never released 128GB microSD card (they don't have such product on their web-site).
But some idiots do buy this junk (it's probably a 8GB card hacked to report itself as 128GB).
Recently, I bought Samsung EVO 64GB microSD on eBay (well, first 4 purchases from different sellers were a disaster - all were a counterfeit). One of the sellers was even a power seller (621 feedback, and not a single negative/neutral one).
I was a buyer #45 of that card, previous 44 buyers bought this junk card and left a positive feedback (either they don't know how to check an SD card, or they left a positive feedback too soon, and now they can not change it).
I was the first one who reported (tested with H2testw) that this card is a FAKE.
Still ... people continue to buy (they don't get bothered with a "COUNTERFEIT card" negative feedback).
Seriously?! If you don't pay attention to such feedbacks, you deserve to be scammed
Only the fifth one was genuine EVO 64GB microSD card.
95% of all microSD cards (64GB and larger) on eBay are fake. Make sure you know how to test it BEFORE you start to use it.
Added: genuine EVO 64GB microSD card works just fine in my HAM2 (at full capacity, though had to reformat it inside the phone - HAM2 did not like default exFAT format)

This is why Amazon is your friend. If someone does you like that you can report them and 99.9% of the time Amazon will side with the buyer.

I would always and highly recommend one format the card in the phone. That way it always works best -- whether it's a phone, camera, etc...
E.g., That's what I did when I got my Sandisk Ultra 64GB C10/UHS-1 (Amazon-US). I stuck it in the HAM2, and it immediately offered to format it (FAT32) when I went to Storage, as it couldn't read it (ExFAT).
BTW, for those that don't know, a few things to always remember ...
- In all NT-based Windows (2000, XP, Vista, 7, 8), Microsoft has always defaulted to formatting NTFS and, in more recent years (Windows 7 and 8), ExFAT is offered for devices greater than 32GiB (33.8GB)
- FAT32 has always supported up to 128GiB (137GB), despite the default in Windows' tools, although it does result in a rather large cluster size for 64GB and 128GB devices
- Last time I checked, ExFAT is required for the SDXC branding, and some aspects of UHS performance guarantees, hence why >33.8GB cards come pre-formatted ExFAT
- Because of some of the design to NTFS, tied to the system that created it (long story, has to do with Access Control Entries, ACEs, for security), ExFAT is safer for mobile use
- Microsoft enforces the ExFAT patent far more often, whereas the FAT design has some prior art involved
Again, the easiest way is to just stick the card in and let the device format it. That way it's guaranteed to work with the device. I've just learned to trust this from years of dSLR cameras.
No device I've used in 64 or 128 capacities have given me the ability to physically format within the phone itself. Just reads "Blank card". Then when I tap "Format" it cycles the notification to "Checking card for errors."
Does this on the HAM2, Nvidia Shield, Samsung devices. How are people formatting within their devices?
Also, FWIW I have tested a Sandisk 64GB and 128GB Extreme card (the 128GB is now in the Shield as it's getting quite full of games).
Used "guiformat" (there are a couple other tools floating around) to format to FAT32 (also works on flashdrives and external HDDs).
It works. You can't re-format the card from within the HAM2 though (tested 64/128GB). If you hit "Erase SD Card" it will remount, show "checking for errors", then dismount. And it will continue to do so until you re-format it using a FAT32 program on another machine.
Also, Can't use App2SD but Link2SD works (got "pro" licenses for both).
FWIW both cards were correctly aligned by SDFormatter before being converted, and there are no issues in other devices.
