HTC Desire - SD card issues

from y'day.. sometimes i get the below message when i switch the phone
"phone could not able to backup data to SD card"...
The phone seems to lose access rights to the SD Card, so nothing is displayed in the file manager (estrong or Astor) The only way to fix this is to restart the phone.
in the phone settings-> SD scard option, I still have the option to unmount the SD card.. but then I don't know who to mount it back.. the only way i am able to fix it is by restarting the phone...
from y'day till now I got this problem for 3 times..
Anybody else having problems with this? please help..

Hi, I have the same issuses. It is very annoying, especially when taking photos. I tried reformat card, but it worked only for a week. I have got euro version, firmware 1.15.405.4. I hope HTC will solve this issue together with multitouch issues in next firmware.

I bought a 16Gb card and cannot get it to work in the Desire.
I've tested it in the PC, formatted it etc but it still won't work.
I'm not convinced where the fault lies, with the card or the Desire.

I had a problem once with sd+camera app, but after a reboot everything worked

funny enuff. that happened to me 2 yesterday ?

One of my 16GB cards also got corrupted. I found it did not slide into the SDHC card slot properly and did become dislodged. Check to see if the SD card is inerted correctly. My replacement 8GB seems fine.

I have 16 GB Kingston Class 2 in my Desire and no problem so far, quite cheap too.

I have had this a couple of times.
Install the SDMount Widget. Unmount the card in settings, click the widget, back in business.

I'm experiencing this issue about once a week... :/

This doesn't work. I have the same problem as described above. I just ordered a new 8gb SD Card. I hope it's an SD card problem and not something wrong with the phone

Thread with same discussion here if you wanna check it out.

I've also been having SD card issues since I got the phone but yesterday things got worse!
After the problem occured again, I thought I'd try removing and reinserting the SD card (despite having done this before). When I restarted the phone it came up with a this message on the notification bar:
Blank SD Card
SD card blank or has unsupported filesystem.
I've tried reformatting the card in the phone, with the phone attached to my comp via USB, and with the card in a card reader. None of this works; the computer just doesn't recognise the card.
I've just emailed HTC support with the problem. I'll report back when I get an answer.

Also 16GB issue
Since a few days I have issues with my 16GB card also. I tried to install Navigon on the card by copying files directly to the card. After inserting it into the phone two out of three directories were empty....
Trying to copy fromt the pc to the Desire using it as a disk drive gave me the blue screen of death
I tried to install it using the original 4GB card and everything works like a charm
I tested the 16GB card (forgot what tool, it was a 1 month trial without write testing) and the card came out fats enough and without any bad blocks.
I will do a write test this evening (EU time) to see if I can fit 16GB ont the card, but everything points to the phone at this moment

I've had exactly the same problem which I posted about in another thread. Do let us know if HTC get back to you

Same problem with my Desire and a Sandik 16 Gb Class 2...
The card works fine on my mp3 player, but it is not recognized by the phone. I'm going to contact HTC, too.

My Desire has complained twice now that my 16GB SD card is damaged and needs to be reformatted. But when I put it in my Nokia N97, it works fine. The last time I did a disk check in XP, and that took care of the problem for a while at least, but it seems strange that the problem appeared in the first place.

Having invested in a 16gb class 2 Kingston card for my desire I can tell you that it brings nothing but grief. I then purchased a 8gb class 6 pqi branded card and found it to be flawless in performance. One thing I noticed with the class 6 card is the very fast speed in copying to and from the card. Much faster than the Kingston class 2. On the class 6 card I have never had corruption of data or any problem. I see comments posted that the class makes no difference. In my experience it makes a huge difference.

you guys are having issues with your 8GB/16GB cards, i was considering getting a 32GB a few days from now, after reading all this i'm having second thoughts.. does size matter ? (pardon the pun)

I don't think the size of the card should matter, but then again - it just might. I was wondering if there's a slight possibility my card got corrupted from when I've had it connected to my computer in disk mode. I only use the "safe disconnection of hardware" button in XP, but I don't select to unmount it on the Desire - it shouldn't be a problem, but perhaps that's how it got broken. Or perhaps it's just damaged and glitchy

Make sure the MBR is formatted too. Windows does not do this by default. Search for a tool on the internet.

SD card unexpectedly removed...

So I have searched for this error and no one seems to have an answer that fits my problem. I got an error after booting that stated SD card unexpectedly removed and gave me a triangle with an exclamation point in the center
the card works fine
it will mount up perfectly from recovery, i even pushed several roms to it and tried (cyanogen, RR, and SkyRaider) all three worked beautifully, but as soon as I boot up BAM "SD card unexpectedly removed" and I can't access anything
the computer reads it just fine so I am pretty sure there is nothing wrong with the card, also with it reading in recovery it seems there is nothing wrong with the phone
is this a problem with ROMs?
I could try to do a factory reset and see if that works... but its really annoying :\
any help?

I would try reformatting the card on your PC. The card may have a bad sector that the PC and Recovery ignore. The phone OS tends to be a little more picky about those sort of things.

Thank you, I am running good now
I noticed when I was trying to backup my SD card (pictures and whatnot) that some of the files were corrupt
I will make sure I keep a regular backup just in case its a sign of the card going bad
good thing is my titanium backups were all perfect

You are on the right path - don't forget, a good practice is to back up your SD card to your PC regularly.
Why? If (when really) the SD goes wonky, you have a PC backup of the card, and you can get another SD, format it on the PC, load the backups you made, and be back in business in short order.

I will def be doing this more frequently

Same problem with a twist

My solution was to format and start over, that was the only thing that worked for me

I've gotten this a few times and it is a PITA because it resets all the notification sounds and also the phone reboots. Once it does it, the only way I can get it to work is to remove the card, put it in the PC, let Win7 do a fix and repair errors and then it will work. I tried removing and reinserting, and it would mount the card and immediately give me the 'sd card unexpectedly removed' message.
I tried reformatting, and the sd card worked for a while and then I got the 'unexpectedly removed" message again after a few days. The last time it gave me that message, I just did the repair errors thing again and it's been working without fail for about 4 days now. It seems like it's going to be an ongoing thing though.
I've been googling like a mad person trying to find a real fix for this. I saw a thread on Android central where they guy said he put his wife's card in his phone and it did the same thing; but worked fine in hers. He mentioned it might be related to the 2.2 OTA update. My problem did start after that update.
In another forum thread, someone posted that they bought a new card, and it gave them the same message. So it doesn't appear to be a bad card; which is what I originally thought. I'd hate to buy a new one and have same issue (i have a 16gb card currently).
(sorry for long post)

I have the same problem! I'm using a Verizon HTC Droid Incredible 2. Previously i've been running Froyo 2.2 over the phone with a 16 GB microSD Card without problem. Later i've been using a 2 GB microSD Card and works fine, but now i'm runnin' Gingerbread ROM From verizon with 16 GB microSD Card and the messages "SD Card unexpectedly removed" don't stop.... the card works fine over other phones... even the stereo of my car can read perfectly the card's content.
I don't know if this is a problem with the update or what????
I don't think in the versions of "Bad sectors" because i check everthing and the problem persist.
The problem appears when i'm playing music... later of that the problem appears at the camera, the file explorer or another app that tries to read the SD Card.
I reboot the phone and works fine but after a couple of minutes the same [email protected]$%&t appears again....
I'm tired of reading forums telling me that is a problem with the sectors... that is a LIE!
no matters the class of the card because i've tried with Class 2, Class 4 and works fine.
This night i'll go to the store that solds me that coursed card to change it!
if tomorrow my problem was solved i been writing at this same forum!

I do not think someone saying it is bad sectors means they are lying.
I think they are merely trying to help you determine what the problem could possibly be.

did you format the card and try again as suggested earlier? That usually clears up any issues with sd cards unless they're fubar'd. Just make sure you back your card up first.

Whenever my card does this I put it into my Windows computer, right click on the card and go to properties/tools/error checking/ and check both boxes and let it run. It fixes my issues every time without formatting the card.

I had that problem a while back with one of Verizon's updates after 2.2. Reformatted card. worked fine in other phones but still said same thing everytine I put it back in the dinc. Ended up getting a new SD card then all was fine.

If you have an ext extension on your sd use G-Parted (google it) to format your ext2/3/4 partition.

[Q] Repeated Failure of micro SD Cards

Is anybody else experiencing repeated failure of micro SD cards? EVO has been rooted and working great since last year. Suddenly, in February, my 32GB sd card failed on a reboot from flashing an early CM7 ROM. The Message is "SD Card blank or has unsupported filesystem." I called Sandisk and they sent out a replacement. Two weeks ago, same failure. Called Sandisk again and they are reluctantly sending another card (supposed to arrive today). In the meantime I was running with my 8GB that came with the phone. I just installed the stable CM7 release, restored data via clockwork and BOOM! SD card failure again. So, is anyone else getting this? Three SD cards in 2 months is kind of extreme. I'm trying to determine if it's the hardware, the ROM, or a series of bad cards (unlikely).
Some additional details:
All cards are Sanddisk
Recovery is ClockworkMod 3.0.0.5
HBOOT is 0.93.0000
Card is not readable via a card reader

its a bug with CM7

Thanks. I searched the forums, but was unable to find anything. Do you have a link to a discussion about it? Thanks.

sorry i dont have a link, it was some thing i read. a simple reboot was the suggestion and it worked for me also. good luck to you

I have had a similar problem with my 32 gb card.
Patriot card, Amon Ra 2.3, hboot 0.76, card worked in my laptop, and now is recognized in my phone, but Titanium backup will not recognize any app data elements

Delete the LOST.DIR on the sdcard while in recovery. Tends to fix it.

I posted this in one of the accessory threads, but it probably belongs in here.
------------------
I got a lexar 32gb class 10 microsd about a bit over a month ago. The first one worked great for about 3-4 weeks, then I started getting data corruption. Reformatted, copied data back, lasted 3 days. Now mind you, I always shut the phone down properly.
Rma'd it, got the replacement. Lasted all of 2 days before file corruption began again.
Lexar insisted I send my old one back before the send a replacement out. Fine. This ordeal took nearly 10 calendar days. During this time I had the stock sandisk 8gb class4 card. The data copied to the lexar is identical to that which was on the sandisk. Only difference is, I had no corruption what so ever with the sandisk.
Thus far, the conclusion i've drawn is that these bigger cards (or faster?) don't seem to work well as a virtual hard drive. They may be fine for storing pics or mp3s. However, the evo uses the sd card more so as random access read/write type storage, with the card constantly being updated by receipt of email, and other system programs/processes. Maybe this is what does the card in.

finally someone with the same problem as me...i thought i was the only one my 32gb card does the same was there a fix for it??

My 16GB Transcend card just died a couple of days ago. Sending it in today for replacement. I can access most folders from a USB card reader, but the larger folders can't be accessed.

This is actually very interesting. Earlier this morning I was thinking about App2SD and started looking into using it, and saw comments that peoples cards were getting nuked after using it (albeit only a few people). This kind of jives with the above quote... but take that sentiment with a grain of salt, admittedly I'm still an Android noob.
To those who are experiencing corrupted card issues, are you using App2SD?

Wrathx, I am set up with an ext3 partition using the dark tremor's a2sd scripts. I only have the apks on there however. The rest of the /data content (config files, databases, etc) is still on the phone's internal memory - for the same reasons above. I figured the internal memory is better (faster?) equipped to handle ever changing content. So in essence, once the apk is on the ext3 partition, it's accessed as a read only process.
My 8gb stock sandisk card is partitioned identically to the way the 32GB was, 32mb swap, 512 mb ext, and the remainder as /sdcard. It's also being used in the same way (only apps moved to it, no other content). Again, no issues what so ever with it.
Now, the the cache and dalvik cache are both set up to use the phone's internal /cache partition (for reasons above). I mention this because dt a2sd script gives you a number of options on how to set this up. Some people may have their cache and/or DC on the ext partition in addition to possibly having the actual /data content including settings on there as well.

so is there a fix r is everyone running into the problem getting a replacement???

When my SD card failed I took it out and put it in my husbands phone ( LG optimus) and let it power all the way on then took it out and put it back in my evo and it worked perfectly after that. It's a 32 gb sands....hope this helps

Just blew up card number 4. This one was a brand new SanDisk 32 GB. It failed when I powered up the phone. Just as a precaution I did not do anything out of the ordinary other than put some music on the phone. Did not transfer apps to SD. I'm going to restore to stock today and exchange the phone as a precaution. Since there is no clear evidence of the cause (even though it only started happening since switching to CM6/CM7) I may just go with straight stock root for now. I'll update if that causes any failures. I seems to only take a couple of weeks to get a failure so stay tuned.

has this worked for anyone? Once i reboot i just get 'blank sdcard.' this is the 3rd card that got hosed for me. all 16gigs. really wondering if its the hc cards, cm7, or just my phone.

My repeated failures turned out to be a bad slot on the phone. I would unroot the phone, restore stock, and exchange it. Since getting a replacement I have had no issues.

Damaged SD card?

Hey,
So ive been having some problems since i got my T989 in november. About once a month my SD card just seems to fail... like just now, i rebooted the phone (power off then on) and it comes up with "SD card is Damaged" Why is this happening? its getting really frustrating because i like to do all my nandriod backups onto the SD card...
Anyone got any advice? Could the card be faulty? The other times it was basically doing the same thing. Eject the sd card properly, remove it, plug it back in... Failed!... ugghhh.

Sounds like it is just that...sd card is faulty. They are so cheap that I'm not sure why you don't just buy a new one?

When I turn on my sgs2 this morning, I suddenly get this message:
damaged sd card
you may have to reformat it.
why is that? what caused it?
does anyone know?
because there is nothing wrong last night when I turn it off.
is it possible to fix it without reformatting it ?
I hate losing all those datas.
my sd card is transcend class 10 16gb, I have used it for only 3 months with no problem at all.
I have tried reboot several times, take it out, clean it and insert it again,
but nothing works.
Please help.
My rom: wanamlite v6.7
My kernel: Phenomenal Black v2.1

Try putting it into your computer and see if it opens. Also, windows may offer to fix it (which shouldn't reformat it).
Either way if you can get it to open on a laptop or something even for a bit you should be able to save your data.
Freezer trick (like for fried harddrives) might also work.

Why did u buy transcend sd card?i am using Kingston 16 gb class 4 card and i think it gives the best performance.Class 10 sd card should perform better than class 4.You may consider sandisk as second option.I am sure u are gonna lose ur data.

Hi Guys,
thanks for all the advices.
when first I connected the sd card to windows, windows could read the directory.
however, if I click on the file, it gave error message: file not found.
then, after did some searching on xda, I found more similar thread like this.
and some told me to run window error checking and chkdsk /r.
the problem is, it seems that every time I run these program, the sd card is getting harder to read.
then, I run them again and again, finally the sd card now can not be read at all.
Too bad, I guess it is time to reformat.
PS. I should do more reading and searching before I run chkdsk:

32gb sd... Help?! [FIXED]

Hi, so today every time i would boot up my phone i noticed it took a really long time to recognize the SD card (32 GB SanDisk class 4 micro SDHC). Later in the day, aka a few hours ago, I rebooted my phone and it flat wont recognize the card is there. I've tried formatting through my computer, still didn't recognize the card was there. I tried formatting through cwm 5.5.x recovery and all i get is an error saying it cannot mount the SD. The only time i could even get it to recognize the card it said it was either blank or written in an unreadable filesystem, so i clicked format, but it seems not to format the card. I tried popping in a blank 4GB (micro SDHC class 4) i had laying around, and it worked no problem.
PLEASE HELP!!! I cannot fit my 14GB of Music on my tiny 4BG SD!!!
Thank you to anyone who responds in advance

I used the format SD program in the link provided by 216Monster below.
This program takes hours (I did a full format) but it works!

Download SD Formatter from https://www.sdcard.org/downloads/formatter_3/ and see if that works for you, might end up with the same results.
Also did you try sd card in something other then your phone to make sure its not faulty?
