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.

Becareful buying micro sd cards on Ebay. I got scammed a few months ago. Bought a 32gb micro sd class 10 card for what I thought was a very good price. When I hooked it up to my computer with an usb adaptor it was recognized and showed 32gb in size. When I tried to move a large file (10Gig) it said "no disk space". It turned out to be an 8gb micro sd card labeled as a 32gb card. They installed a program in the micro sd card to show 32gb when you open it up in your computer. I got my money back through my credit card company and I emailed other buyers who bought them from this seller. Funny thing is everyone else thought it was fine and left good feedback for that seller until they tried adding more than 8gb into the card. I would stick with buying stuff like micro sd cards, usb flash drives, etc on Amazon, Newegg, or Frys. Its not worth trying to save $10-$20 or more on a $80 microsd card from Amazon.
Oh yeah I just read the feedback on one seller of the Memorette 32gb Micro SD SDHC CLASS 10 and I read a few "DOA", "not as advertised but refunded", "my computer can't read it". The rest who are happy probably didn't even try putting 30gb of data on the card yet. Again buyer beware.

i have tried the same thing, and the problem is not many is testing the cards.. i bught 3 class 6 before i got the real class 6 card, got my money back the other to times thow, but when buying from ebay always test the card as the first, there are many cheaters out there.
and yaa again the funny thing was that many said this was good, so i pick out 2 or 3 guys and ask them to try it, and guess what, they were cheated as well they just didnt knew it..
Do we know what maximum speeds the TF is capable of? I just read that thread posted so it got me wondering if its worth buying a class 10 card or not. I tried looking online but didn't really see anything about it. Is it safe to assume then that a class 10 will perform to its maximum when used in the TF?
Make sure you test the capacity of your micro sd card. Too many scams on memory cards from China. They will use a smaller capacity memory card and install a program in it to make it look bigger than it is. They use 8gb cards to make it look like it is 32gb. When you get your memory cards test it by adding large files to capacity.
Read the feedback left by a buyer. Many leave feedback before testing out their fake 32gb microsd cards LOL.
By my test it's a class 5, but the buyer is really good and fast!!! NICE EBAYER Member id davidegatto ( Feedback Score Of 62) Apr-22-11 02:50

For stuff like that, it's better to buy from a reputable vendor.
I got a 16GB class 6 card off of Amazon a little while ago to use in my Nook Color. I'll be using it in the TF. 16GB will be plenty of storage for me. Maybe when 32GB cards are a bit cheaper...
Sucks that tablets didn't go with full size SD card slots. I'd have much preferred that. 32GB SDHC cards aren't that expensive.

I hear you! a SDHC slot doesn't take up THAT much room. It's a shame they only included it in the keyboard dock I don't always want to carry around my dock with me
Also as a photographer, it's kind of a shame to not be able to plug in my camera's SDHC card directly into the tablet to view the pictures
Seen a fair bit about fake cards. Just as well I have paid through paypal using my credit card just in case.

MicroSD's aren't fast enough Slow SD cards really limit how many shots you can take in a row. I tend to do a lot of burst RAW shots and if the SD card isn't fast enough, the buffer will fill up too quickly
what class of SD are you using? People are purchasing class 10 microSDs to use with the transformers at reasonable prices.. still not fast enough?

No no no no never use memorette. I did, got a 32g card for 50 bucks. Put it in my mac to transfer 25g of stuff. Stopped unexpectedly after 20, after that it won't be recognized by either my imac or my phone, won't even allow me to format using terminal in the mac. Beware!

To anyone out there that has used Micro SD Cards....
1) First of all, I know the A101IT supports SDHC Micro SD Cards but does it support any 32GB Micro SD Cards at all??
(All the 32GB Micro SD Cards I've seen show the SDHC written label on them).
2) If the A101IT does support the 32GB Micro SD Card, what manufacturer brands along with their Class #'s have been found to work when tested with data and media in upwards of 16GBs in this case.
(I.E. - SanDisk 8GB Class 4/... Works for me on my A101IT).
Reason:
I want to put my Band of Brothers HBO TV Show Series (7.20GBs), True Blood HBO TV Show Series (19.3GBs), about 1-2GBs of music, a couple DVD Movies, and finally leave the few remaining space on the card for Market Apps and put ALL this ^ on 1 card because I don't like always carrying around my external portable 500 GB HDD. I have an 8GB Micro SD Card and I need more space on it so please advise of bigger and better cards. Thanks!
In other news:
From sources I found on Yahoo and Google, I read that SanDisk is in the development stage of working on a 128GB Micro SDXC Card for mobile devices AND a 128GB SDXC Flash Card for devices like digital cameras to which both will reportedly be available by the end of 2011. Reports show that for the 128GB Standard SDXC Card at 133x speed made by Lexar is roughly $700 and the 128GB SDXC Flash Card at 100x speed made by SanDisk is $1500! So if the below configuration of HC/XC is what SD says it is then in the coming years we should see a 2TB Standard SDXC card for like $5000 and a 2TB Micro SDXC Card for like $10,000?! Then fast forward and imagine about 30 years from now where we would have a double-sided Micro SDXC Card with like 6TBs total (3TB on each side) as the total amount of space on the card and costing like $20,000?! ... Yay, can't wait... *(sarcastically).*
SDHC: 4 GB to 32 GB
SDXC: >32 GB to 2 TB
Yes the Archos can handle any non fake 32GB microsd's.
I specifically say non fake because if you buy them cheap it might be one that doesn't really hold the data ( had one given to me that was fake ).
And for the price of the SDXC Crads.
I bought a 540MB harddrive for DM1500 in 1990, because i needed the space then.
About 1 year later it was around DM500.
Now you get 1TB for €50.
And with this its the same, when they produce more, price will drop dramatically.
Well I got 2 different 32GB Micro SD Cards. One is by Kingston at a Class 4 & the other by a no-named company because there is no name on it and that one is at a Class 6. I formatted each to NTFS, FAT32, AND extFAT and absolutely none of it works like it should. For each card I put like 6 GBs on them and loaded them back into my A101IT and only part of the stuff comes up that I transferred to it like my folder of strickly .apk's, a few but not all of my documents, and the folder I made for the Swap Files from another thread here on XDA. Other stuff on the card like the folder of my Movies, Band of Brothers TV Show Series, and the entire folder of my pictures never show up and it looks like it just randomly deleted the other stuff. When I go to open up either one of my 32GB SD Cards from on my A101IT.... everything but my folder of .apk's are still on the card?!
Is there anything I did wrong in formatting or any way I should format either card? Is my problem that I should use a Class 8/10 Card regardless of the card's GB size??
Most of noname SD cards are fake. Lots of Kingston and Transcend cards are fake too the only way I found is to buy from well-known shops where chances to get a fake are lower and you can get a replacement if something went wrong. As usual cards for $90 work better than $40, but you can get a garbage for full price
It seems both yours cards are fake. There are a lot of cards on the market marked as 32Gb and their real capacity is 8Gb maximum. What did you use for formatting?
I've bought mine from Amazon directly and waiting for delivery. It was $60 for 4 class. I'm worried a bit but hope for better
Well after formatting both 32GB Micro SD Cards on my laptop, I found that both cards are truly not fake and each of their real capacities are at 31.7 GBs and 30.9 GBs respectively. I was thinking that they just had some kind of read/write problem but I formatted both cards to the default NTFS again for like the 4th time and now they work on my A101IT?! I think the problem lies with my Toshiba laptop's USB ports and its built-in SD Card Slot because my laptop is like 6 years old and holding onto a thread to keep from dying (I've been having other non-SD Card related problems lately too). But I think it's solved now because the cards both work.
Does archos support ntfs for sd card ?
So my phone freezes sometimes and I have heard others having the same problem. This happens a lot when using the camera.
I was told it is not the phones fault but the SD cards fault.
Could anyone recommend a good SD card for me to replace the stock one with?
Also how does it work do you jsut put the new one in and your good to go? What happens to all the apps and information stored on the stock SD card?
Thanks for the help,
Dakota
Get a class 6 or up. I have a 32 GB class 6 Kingston and have no problems with freezes.
In order for everything to be the same from one card to the next, you'll want to copy everything over from the old one to the new one on your computer if you have game data and such. Make sure you set your computer to "view hidden files", because some of the data may be hidden.
I have a Patriot Memory 32GB Class 10 and its quick. 9.2+ write and 22+ read. I didn't reformat it or anything so I'm sure it can go faster. When I transfer files from my computer to the device its almost a perfect 10Mb/s the entire time. I bought it at Frys.com since it was cheaper than newegg.com. Go to patriot memory to find the best prices, they list 8 of their online seller and I chose the cheapest one without a mail-in rebate.
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.

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

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 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.

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.
