Mini SD trouble.

Just trying to upload a few files to my 1gb sandisk and found that some files and directories had just become a jumble of characters and after a soft reset my programs that were stored on the card refused to work.
I had the phone reasonably close to my monitor at work on the desk, could that have been the prob or is my card going to die ?
Formatted it on the PC and its back to normal for now. Just re installing everything.

i got the same thing just now. all my games and programs stored on my miniSD card dont work! what the heck?

Is it some form of magnetism interference or power surge or what ? I was plugging my phone into the usb attached to the computer at the time when I first noticed it. Everything had been runnning fine before that.
Hope its not going to keep happening on a regular basis.

It happened to me too, I think it is due to two programs trying to write to the storage card at once, or something reading while some else is writing, or similar.
I wiped mine and fortunately was able to replace most of what was on there (mostly music) but found out afterwards that there was a good chance of recovery.
Try checking out EasyRecovery Professional, there is a free trial I beleive and you should be able to recover files on your card (even if they have been deleted and not yet overwritten).
Hope this helps

corrupt SDCard wont format.

ok.
my SDCard is ****ed, basically. i thought a good old format would do the trick but i was sadly mistaken.
it can read and display pictures, but cannot display thumbnails.
it shows mp3 files in file managers but wont play them in any music player.
will sometimes let me copy files from the card to the computer but not the other way round.
files cannot be deleted from the card at all.
and now the strangest one, it seems to be unaffected by a complete format.
the format finishes, i can then open up the card (which now shows as empty) from the computer and move files to it, so i eject it and remount it and low and behold everything's there again except for the files i put on after the format.
i don't know what to do as i can't really do much without an SD card =/
anyone got any ideas?

same. mine's been corrupt for a while now with reformat only making it work for a few hours/days.
i'm not sure if this is the crappy card that came with it or the g1's fault...has there been many cases of this?
i'm just buying an 8gb microsd from microcenter for $20 in the next week...i'll deal with my current one until then.

Just buy a new one, its not like they're expensive.

My brand new 8 GB Kingston MicroSD(HC) simply refused to cooperate - The G1 never saw anything I wrote to it on my computer - the computer never saw anything saved by the camera to the microSD. To boot, it even only reported as < 500 MB on the G1. Using the HP USB mem tool (http://files.extremeoverclocking.com/file.php?f=197) I came to the point where the G1 saw 4 GB, but still no way to transfer anything to or from the computer.
Finally, I found this http://rivviepop.wordpress.com/2008/11/11/fix-your-g1-android-messed-up-sd-card/ (requires Linux) that solved the situation. Now both my computer and G1 sees all of the card, and what's on it.Phew!

HD2 destroyed my SD card?

Hello.
After trying the android booting, for 5-6'th time (all working), now the phone can't see the SD card. I thought it was only on the phone, but when i insert the card, in adapter and connect to pc, then NOTHING happens. Like if the card wasn't there.. Hmm, any clue? Usually I just formatted. But now, I can't format a SD card which "isn't there."
Please.

any one??? :S

Sounds like your sd card maybe corrupt, they can die for no apparent reason, its happen to me twice in about 4yrs, tho i always buy from CEX they offer a 1yr warranty & just replace it if its within that time.
There's been a few threads about this;

What is the brand of the memory card?

hey dude,i got the same problem as yours few days ago..cant do much abt it,i just buy a new one..some says the htc that makes the sd card problem

Hi,
My 8 GB sd card lags when i`m scrolling in the file manager.
In addition, the sd card drains the HD2 battery. I loose 35% in 6 hours in flight mode, but only 4% when not in flight mode without the sd card... ( this also yields for the original sandisk 2 GB sd card that was supplied with the phone).
Anyone experienced the same issue?
Is this hardware or software related, and can i fix this myself?

Error check your microSD card using your computer then switch your phone off, put the card back in it and switch your phone back on. The phone will need to index your music/video files etc so go to the relevant tabs and let it do its stuff. See how that helps.

i got a new HD2 and it came with a MicroSD card. I put a couple of cooked ROMs on it and everything was fine for about a week and then the card jsut stopped working. I didnot use it on any other phone or on my PC and it just died.
I own an HTC Hero as well and i put the card in it but it wouldnt recognize it. It has never happened to me before. Never has a card died on me.
I think its a problem with the way the HD2 accesses the SDcard. I wouldnt know specifics but this is the first phone that fried my SD card.

Hey guys, I had the same issue. The SD card stopped working and cannot be formatted now via computer.

My experience with Windows Mobile is that the SD/CF driver is the weakest link. The problem seems to be simultaneous accesses drive it bonkers. I've had the disappearing card problem on other PDAs but usually removing it, doing a reboot with it out, and then inserting it after the reboot is complete will fix it. If it doesn't show up immediately DON'T do anything for a while, it could be doing a CHKDSK on the card, and if you mess with it it will screw it up worse.
Once it shows up what I would recommend is hooking up via USB in CF Disk mode (not Activesync) and doing a format on the drive from Windows.
Last night I got a new 32gb Class 4 MicroSD from China (unnamed) and stuck it in, worked fine, so I backed up all my data to my 'puter off the T-Mobile Class 2 16gb and changed to the new 32gb SD. I started the copy and after a while went to bed.
This morning I got up and it had died during the copy. It was giving me an error on the new MicroSD. It had copied about 75% but was asking to continue or skip. I ended up having to cancel it because it appeared full but it was not. After a reboot I found a ton of FILEXXX.CHK files which indicated it was doing a chkdsk.
Looking at it with SoftWinter.com's Storage Tools the disk was formatted with 512 byte cluster size, way too small for such a large disk, so it was not really out of space just out of cluster nodes. If you have lots of files (I had 10,000) each takes up at least one, even if the file is only 5 bytes. So I reformatted it from the 'puter to 32k cluster size and started the copy over. Seems to be working better now.
Please note that using larger cluster size also will help performance when writing and reading large files as it has to do less directory accesses. Small cluster size is good if you have a lot of small files as it doesn't waste as much space. You lose on average 1/2 the cluster size for each file, as the last node is almost never full.

Hey
i hope for your sake im wrong, but as far as ive been able to find out in my own searching, only san disk has released a 32gb micro sd & its only class 2.
there has been a lot of talk of fake 32gb micro sd's from china, most are actually 4gb re-programed to read as 32gb on your phone or pc, but when you start to fill them with files more than their actual capacity they will only overwrite prev' files & become corrupt.
i actually pick up 1 (32gb) last weekend from a local store, tried to copy the contents of my 16gb, 7gb copied then an error occurred, 2nd attempt 9gb copied but files unreadable by phone or pc, fortunately i always buy from this store & they refunded (£50), straight away, still have 2 16gb cards ive had for about 9mnths with no probs.
there is another longer thread over in the Q&A section, you guys may find some useful feed back over there: http://forum.xda-developers.com/showthread.php?t=646731

Well, the one I got says SanDisk and I have done a full format and surface analysis, it checks out, but I am having trouble writing to it. Not sure what is up with it right now. I knew it was a fake but I thought it was a real fake, not a piece of junk. I hope you are wrong.

I´ve got problems too. I have two SanDisk 16 GB microSDHC cards and both of them are giving similar problems.
I´ve got my HD2 a few days ago and initially I used my old 16 GB card I bought with the X1 (then used with my TP2 and latest the HD2). Everything was working fine initially but then the problems arose. Now I have those problems:
1. Audio Manager has problems reading my music library. iPlay can read it though. Windows Media Player takes a long time building my music library but manages to do that eventually.
2. HTC Album can read my albums sometimes - sometimes not.
3. Resco Photo Manager can read the albums but sometimes it takes a long time to do it.
4. The computer can access the card without any problems after formatting and it seems not to be any problems reading or writing files to it. Installations of cabs stored on the memory card works.
5. Total Commander can access the card without any problems but takes slightly longer time than before to show all folders.
6. Running chkdsk in Windows gives the result of a perfectly working card.
7. The phone is draining battery in an abnormal way with the card inserted.
8. Flashing ROMs from the card worked initially but not any longer. Now it shows the threecolor bootloader screen instead.
The interesting thing is the fact both of my 16 GB cards has the exactly the same symptoms. I will try them in my X1, TP2 and Vivaz later to check out their behaviour.
When I inserts my old 8 GB card (everything made by SanDisk) everything works without any problems. Flashing ROMs work normally etc.
I´m running the Omega XT 3.0 and are using HardSPL3. The 16 GB card has worked perfectly initially with this ROM and HSPL so I don´t think they are related.
The whole thing seems to indicate some kind of "incompatibility" between the phone and the 16 GB cards. It´s like it is unable to handle that size of card correctly. It seems like it "trashes" the file system. My older 16 GB card started to behave badly which caused me to buy a replacement and now that replacement has the exactly the same behaviour.
My 8 GB card is an "ultra" SanDisk card. The troublesome cards are Class 2 cards. I began to have the impression the problem is some kind of issue with Class 2 - because the cards itself seems to be working after formatting.
I have formatted them with either Panasonic SDFormatter and the Format SD application on the phone. Both options gives the same result.

microsd card care

OK, here's the deal, i got a 32 GB micro sd card ( class 10 ) about 4 months ago now and twice in the last 3 weeks it got corrupted. Some of the files were still available but for the most part, about 80% of all files were unreadable. The first time it happened was after unmounting my card from a mac, the second time i was unmounting from a pc but it was only charging.
I know it might be that the card is dieing or that its a low quality card but does anyone have any specific rules or un-mounting tricks that would reduce the risk of corrupted files on the sd card?
I am always plugging my phone into multiple computers for file access so it has to be something that i can initiate from the phone end.

Do you turn off Disk mode on the phone before you pull the usb cord out? If not, that's generally a good thing to do.

well, which should you do first? turn off disk mode or eject from the computer?

After having that happen with the 16GB SD card in my Nook Color, I pretty much avoid removing it from the device as much as possible. With the Evo, just use disk mode and transfer files that way without ever taking the card out of the Evo. If you ever do remove it be sure the "unmount" it frist from the phone, and eject properly from the computer.

I don't bother with the computer end, for any USB devices. I guess if you did want to do both you'd want to do the computer end first, since disabling disk mode also mounts the sd card on the phone in addition to unmounting it as a disk.

Did you buy it from an authorized retailer?

i bought it from newegg.
well, i"ve noticed that it happened once when i ejected from the pc frist and then frpom the phone.

turn off disk mode...wait till your phone settles and then yank the cord.

Slow PC to Phone Transfer Speeds

Hi All,
I've searched the forums and I'm unable to find a resolution to my problem.
I'm having horribly slow transfer speeds from the computer to my Atrix internal SD card. I am transferring about 7GB of music from my 64-bit Win7 PC and status says about 4-hours. Used to only take a few minutes on my Captivate.
I've tried formatting the internal card, re-flashing back to stock, different USB ports on the PC, etc all without any luck.
Any ideas before I completely tear my hair out?
Thanks in advance.
EDIT: When the internal SD gets mounted, Windows is slow to find the drive and list its contents. The 2GB external that I have in the phone comes right up.

Wow. No idea. Iwas quite surprised at how fast toshiba emmc is. What speeds are you getting btw? Oh, i do know one thing possibly. Do you transfer files a lot? Flash memory has a limited life, though many of us never see flash die or start to die. But if you do these types large file tansfers, 7gb often, youre using up write cycles much quicker. Also, the folder youre transferring to is about 12 gigs right? Say you have 4 gigs of stuff in their already, and youre trying to put 7 gigs in, more than likely youre transfer speed will be slowed down. You need space to actually to fill stuff up, and the more space, the faster you can fill it up. I wish i could be a little more detailed. I know about this from solid state drives, and the concept is basically the same, but works a little different. I dont know if that is your problem though.

Take the SD card out of the phone and put in the adapter. Try measuring speeds via adapter. Your SC card might be dying.

His internal card.

Just thought I'd throw this out there, when you format an SD card it asks you for the amount of "bits" you want to format it with. I would research which number is best suited for your particular SD card depending on how big it is. Cause the standard number it automatically inserts may not be the best.
edit: ignore post. For some reason when I read it, my eyes saw external SD card instead of internal. Derp and Derp.

Which of the four (well, three) USB modes are you using to do the transfer?
