Had the device for a few weeks now. Randomly the sd card was dismounted. No biggie, was able to mount it with a remove/insert or reboot.
Suddenly today it isn't possible to find, mount or read anything from it.
Can't read it through an usb-stick in the pc either. So the only possible reason is either a bad sd-card? Or the hero destroyed it?
Edit: This was a none branded 6 class 8gb. So my advice is to stay away from the bulk cards.
Back up all your stuff - which fortunately I had done
Exactly the same thing has happened to me 8gig class 6 etc. now unreadable -- interested in the reponse / cure suggestions from others on the site.
Well,well. I have a 16gb Sandisk card. Has been running perfectly in a Touch HD. Now is running in my Hero.
Turned on the phone this morning and it wants to format it. Lost alot of my photos so now I am worried.
This has never happend to me before with a quality card
If you can format it, it will still be accessible.
This has just happened to me. 8gb class 6 unbranded card is not recognised by the phone so I can't format.
It has happened in the past, but i could format, or restarting fixed it.
Any ideas, will trying over and over fix it?
My new 8gb trendmicro card keeps on unmounting after a couple of minutes. Any idea whats wrong? Faulty card or hero bug?

Same happend to me today with a ScanDisk 8GB class 2 card
Possibly it's a specification/compability problem, perhaps something related about hybernation specification.
I have two Nokia SDHC 8G cl6 absolutly incompatible. When the phone going to sleep, at 3-4 min sd is unrecognizable and megacrash ... A2SD is very unstable and when I had formatting all with FAT32, crash with bad structure file system in hybernation mode, loss data,......
The Chaos.
I will try with Kigston 8G cl6, I have good references about on it.
NOKIA never more...
***Using MoDaCo 2.0e ROM***
Sorry for my english
I have two 8GB Sandisk MicroSD card killed by my HD2 (i think so). Anybody faces the same prob? The cards are totally dead now after using it in my HD2 for a few days...
No such experience.
Good to know the Bland and model.
You mean brand?
Try to format it on your pc...
I had the same Isue.. could not format it on xp pc only on windows 7 pc..
mos of the time if you let you put it in your card reader and its recognized.. you just have to let it scan for errors and let it fix them..
Sometimes my cardreader fails to detecet my card. I don't think this is related to my HD2, atleast I don't hope so.
Not had it...yet...on my sandisk 8GB MicroSD. This is the one straight out of a Nokia 5800. The 2GB one which cam with my HD2 went tits up after I tried to import a playlist from WMP onto it. Seems I'm not alone with this issue either...
For the first time I can report a problem with my HTC HD2.
I also seem to have a problem with my 8Gb Scandisk card. It seems either my telephone or my laptop screwed the card up.
I have standard stock last rom available in Holland manilla 2.5 Rom 1.66. No special things installed.
The card works almost 100% except when I go to the tap music. Then hell breaks loose. The phone looks for the music files. But cannot find them and then suddenly the phone cannot recognize the card anymore? I have to restart the phone before it can recognize the card again. This only happens when I go to Music.
But the damage is done anyway. Cause when I insert card in laptop or computer. I can see the files but according to the computer there empty (which is not the case). I cannot copy or cut while in card is inserted in the computer.
I accepted this problem cause I have a good working TomTom on it which someone else installed for me. If I format the card I cannot put it back.
Try to format your card, I did this from my laptop (if it can reorganize it) and NOT chose FAST. Becouse if there is a problem with the card it will simply skip it. This is also a golden rule when you install new OS on a old or well used laptop.
Copy the tomtom folders to a folder on your PC before formatting, then copy back...done
I have a 8GB Sandisk card, I've had it on 3 plones now, using it for about 3 years, still works like a charm.
To the OP, maybe you got fake ones, Sandisk is the most counterfeit memory card brand, if you got them on ebay or so and not in a respectable street shop they might be fakes, for which that kind of failures are typical.

I have this problem, and I went back to HTC. I got a new phone replacement and everything is fine thereafter. =)
I had a problem with 3 different Kingston 8GB cards.
Statred working fine, but after writing more then 2GB to them, they suddenly died.
I tried all of them in the phone and in a card reader, and they acted the same way.
As a final test - I used a SanDisk card, and it works just fine from the time I got it.
So - maybe, you just have defective cards ?
Did you try formatting the cards in the phone and not in the PC ?
I have the same problem. If i put the files on my sd card from my pc there seem to be no problem. After I check these files on my phone, they are damaged or the folder is empty. So.. anyone has suggestions what to do?
Same experience here.
8Gb was working fine the first two days (the card that was included with my HD2)
Then, for no reason got a pop-up (invalid card type, do you want to format?)
At forst I said "no" and tried with my computer... None of the 6 software I used could save my card. Was definatly dead.
Put a second one in (1Gb, just to make sure), it's been a week, and I already get errors when I write. It's like the micro SD is on read only (though ther's no switch to set it back to "write mode")
One of the many (many many many) bugs of my HD2
i had the same problem. the 8gb SanDisk microsd card that originally comes with my htc hd 2 is now useless. lost a lot of pics, cab & songs. it can't even be read by card reader on my laptop. is this some kind of bug?? now im using another 8gb card & hope it wont happen again. im glad though that im not the only one having the problem
And i thought i was the only one. My 8GB only lasted for 1 day before it went died. Had to get a replacement from Service Center. The staff seem to handle it in a very fast manner (guess i am not the only one to get the SD card replaced recently!!)
My guess is i did a hard reset on the phone with the SD card in it. Anyone else did the same thing?
My card has been corrupted twice no the HD2 leading to:
1) Very poor performance
2) Very warm phone
3) Very fast draining battery
I believe it was due to the power saving features enabled to do with the microsd as someone else mentioned on this forum.
its a manufactures defect. something should be done. lots of users are getting this problem now,including me
maybe i know the answer..
sorry for my bad english..
I've the same problem. But searching from all forums, finally i get the answer. just find n download EASEUS Data Recovery Wizard Proffessional 4.3.6 (for 5 MB). Insert the mmc in card reader, use this software to recovery all the missing file (choose Complete Recovery Option). After recovery process done, use software LLFTool (for 600kb, just doing some browsing at google) to Low Level Format the mmc (this LLFTool can recognize the mmc). After all done, Windows can recognize again the mmc at windows explorer. Just right click and choose quick format (format FAT32). Done, you can use the mmc like the new one

thanks for your help. i tried your solution but it doesn't work. neither the EASEUS Data Recovery Wizard Professional nor LLFTool detect the memory card. i think there's nothing to be done for the card. just hope htc will sort that out
I have also recently had an issue with my 8gb Sandisk Micro SD card.
It has been working fine for a while now, then yesterday when I went to pick up my phone, I noticed my S2U2 unlock screen was black instead of having my usual wallpaper there. My HD2 had just suddenly decided it can't recognise the card anymore and tells me I need to format it for it to be readable.
I pressed 'no' and tried to read the card on several computers as I wanted to transfer all data off before formatting it, but it would not read on any of them, nor would it work in my old N95.
I don't understand why this has happened, it has been working fine no probs, had about 3gb left on it still and have not recently installed anything on it - very annoyed as I have lost lots of recent photos of my 6month old boy which I cant get back now.
Have had to order a new card and hope this doesn't happen again, but not a happy bunny
Hi,
I got my Optimus one not long ago and I bought kingston 8G for it though it would work fine. The phone read the card well and show the memory correct and I can use it pretty good on my phone. The thing later I found out is the phone itself restart after the idle time exceed 1hr which is crazy. The phone works really good until I upgrade my original sd card (samsung 2G which came in with) to Kingston microsd 8G. I don't know where exactly is wrong, and I couldn't return the sd card either since it work fine on both phone and on computer with card reader. If someone got same problem with me, please let me know or help me out!! Thanks in advance.
I think it is a firmware problem,Mine and others do the same with the standart 2G card...
Firmware keeps updating itself when I go on WIFI connection. I don't know about these stuffs either. But now, the problems are ended..the phone doesn't read any card anymore whether 2G or 8G, it keeps saying that "sd card removed. Insert a new one". I've tried restart again & again but the message doesn't go away and my phone decide not to recognize the card.Both of the cards work fine on computer. I think I need to visit the shop where I bought to check on it. Btw, is that problem considered in the warranty case? I don't know.. It wasn't even a month with me. So sad!

Are you using any app2sd ? If yes, it could be a problem also if ur using an app storing data on your SD card. It makes you're cell restart.
I have the "mount / unmount" problem on my LG, I saw on a french forum that it was better to try with another file system, sometimes it was solving, sometimes not. I don't think it's really a card problem, I gave my LG GW620's sd to my girlfrend and her old samsung is using it without any problem's, but on mine it was crashing every 30mins....

I have the same problem but more problem when my LG O1 didn't recognize the card and I couldn't mount or format the card on my phone.
This happened when I partitioned the card. My PC still sees the card well but my phone doesn't.
I read a lot of posts from a lot of forums and I did try every guides steps by steps but it seemed as the LG O1 doesn't have any button-press-combination as others. For ex: when I pressed Back + Power On, nothing happened as It was said that the phone might come to FastBoot.
As help on this issue will be in much appreciated.
I fixed it. If your PC still recognizes the sd card, it's ok. Go to Manage (right click on My Computer) -> Device Management -> Storage -> you should see your card there. Try to delete volumn or format the EXT2 and Linux Swap.
Put the card back to your phone. It should recognize the card and then, unmount and format card and mount it back. Done.
I have a small question. What is the best class for this phone? The class 10 is fully used by phone or does not reach that read/write speed? Some micro sd class 10 are declared between 20 and 30 MB/S. The p500 has these capabilities? Or a Class 6 card is enough?
Thanks
UP!
The price for 32GB class 6 is very different from class 10.
Lg Optimus One is able to full use write/read speed of class 10?
Thanks
Help! I inserted a sandisk 4gb class 4 and my phone didn't recognized it (i got the 'SD card removed. Insert a new one.' notification). Then, i inserted back the original 2gb sd card from the box, but that notification is still there and it can't be recognized. But both my PC and a another android device (a galaxy tab) can detect it. So, i tried formatting both the 4gb and the original 2gb with the galaxy tab and inserted it to my O1 but nothing has changed. I tried updating to the official V10E firmware but it makes no diffrences. Any help please?
Sent from my LG-P500 using XDA App
For future, don't remove SD card during phone is running because of app moved to SD card. Especially when you plan insert new one, and if you do that with custom ROM with app2sd its equivalent to suicide.
Is mass storage mode works? Is MS works in curstom recovery? Did you try format memory card in phone? Delete of caches?

Thx for the reply,
I haven't install a custom ROM yet. All i did was enable JIT+HW accel from a thread here.
1. Mass storage didn't work. It just appears as a new drive which i can't access.
2. I updated my O1 to V10E... I lost root, custom recovery,etc. so i can't try that
3. I formated it with another android device (a galaxy tab)
4. How do you delete the caches???? Sorry, new here
You had got me. For now I have not idea how to proceed.
Anyway, remove battery, remove SD card, clean sd card with some soft cloth, check if metal contacts looks fine (try clean that if not), insert SD card, insert battery and try it again.
If this not help, you can try some shaking and so on. It's sounds crazy, but I know one guy whose shaking helped him to flash firmware to phone, which not works at all. Maybe it's some cheats for all these issues.
ad 4) You can delete caches via custom recovery, but related to 2) you can't so, this hint is useless.
I did everything u said. I checked the SD card & the slot and they seem ok.
This might sound dumb, but what do you mean by 'shaking'? Which part are you suppose to shake?? Sorry, im still new to androids
BTW, i went to the LG customer care. The technician checked it and said that they are going to replace the SD card slot. She said that sparepart (the SD card slot) is going to arrive sometime in mid-January due to the holidays.
By the shake I mean grab phone and do quick movements with phone from left to right and back.
But it seems, that you have some trouble with hardware part(s) of phone.

format ur SD card..
if that doesnt fix.. i need to know brand name.. and what class card it is..
does it show up as the correct size in the stock rom?
Try just attaching it to your computer via reader. If it still shows 14GB, try and format. If it still shows 14GB, it's defective (or fake. Did you buy it from Hong Kong via eBay?).

My class 10 card is working just fine...
My class 10 works fine too. It is a 32g Sandisk, it reads 29.81g of total space on my phone and my computer. It seems like the photo galley loads faster and scrolls through the fullscreen view pretty fast. The read_ahead_kb file reads only 512. I haven't tried any other values because i am very happy with the card.
Well to be honest i'm not sure what class it is.
It was in another phone that my dad gave me to sell on ebay. I just kept the card that was inside.
It's a 32GB Sandisk.
I'll try a partition program tonight on my computer si if it fixes it.
If I try to partition it via the Clockworkmod, the lowest I got was 10GB and the max I got was 14.77GB depending on the settings i choose

Use a formatting tool, like the one HP has (see here) to format the disk. It can wipe the full disk and create a single partition. It could be that it was split previously for some reason, causing the issue you have.
If I put back the microSD in the Samsung Focus and format it, it shows the 32GB on the card (37GB with internal memory)
and then I take the card out and put it in my Fascinate and it shows 13.94GB
If that makes a difference i'm on Cyanogenmod 7. Maybe it's the OS limiting the space?
Any idea about this issue?
Format the card with a low-level formatting tool, like the HP Format tool. It's likely that it could be partitioned, or has a partition table that isn't setup in a format compatible with Android.
Any idea why this error occurs?
S9+ forced me to erase my data when i restarted my phone...any knowledge??

Is your SD Card encrypted? I would try decrypting the card first in the device it was encrypted.
i am getting the same thing on my S9. My SD was never encrypted.
verify EXFAT or FAT32 format

Hi there
the Samsung galaxy S lineup ( S7, S8, S9) use EXFAT format for the microsdxc cards
- If you have a brand new microsdxc card, you won´t have any issues if you format the microsd, this will be in EXFAT format ( this format works for to transfer high archives ( plus 4gb), the phone will format to this by default
- If you have a brand new microsdxc BUT the phone can not format: probably the card doesn´t support this format ( EXFAT)
- If you have a microsd that you used in another phone, no Samsung, it´s very probably that you microsdxc is in FAT32 format, this format doesn´t left high size files and more slow transfer speeds. You ´ll need to format, before, you can do a backup
You can verify this in your PC, in windows: file explorer/this PC, search the microsdxc , right click, format and you can check, if you will make a format, choose : exfat ( in format) and 128kb ( in size) and done
I have the same issue with my S9+.
My SD card came from my last S8 and I never had a problem.
I don't know what to do.
Anyone can help me? I don't want to format the card.
Thank you very much!
This CAN sometimes be indicative of a failing SD Card. CAN. Not DEFINITELY IS. Either me and/or my wife has had this issue a few times in the past and its usually always been the SD Card. Her last one stopped working when we realised nothing could be written to it. Stuff that was already on it (such as music) could be read, but nothing new, like pictures or downloads could be added to it. It would work in some phones, and others would say it needed formatting and gave errors and so on.
At any rate, my advice would be back up your data on it, if you can, just in case. SD Card errors don't usually happen when things are running smoothly.
Hi, this is an on-going issue that many s9/s9+ users are having (now a few Note9 users as well). After 6 months there is still no reply/statement from Samsung..
