Droid Incredible SD Card Problem

Hello! I have been searching around the forums for this problem, and I can't seem to find it, so I'll post it here.
Anyway, my rooted Droid Incredible, with CyanogenMod 7.1, as well as my mom's Droid Incredible, stock on Android 2.3.4 recently updated by HTC, have both been having troubles with our 16 Gig micro sd cards. Randomly, after a boot, the sd card becomes unreadable and corrupted, so I had to go back to our old 2 gig ones. As far as I know none of our cards were even close to being filled, with cards at a max only being filled about 25 percent full. Any help is appreciated. Thank you!

Copy contents of both to pc, reformat them FAT32, copy content back onto each, and put them back in the devices. Note that the device is OFF when you remove and reinstall the SD.

Thank you, however I already have done this in the past, because our Droid Incredibles have a history of doing this. However, this time is a problem, because our SD card will not even be read by the computer. I am assuming that whatever important is on there is lost and cannot be recovered, although it would be great if we could. My main problem now is that because the phone or the computer (running Windows 7) cannot even know it's there, I cannot reformat. Any advice?

Can you use the phone to reformat it?

Already tried, still wouldn't do anything.

Hmm, if both run without error with the other cards, I can only speculate the 16gb ones are what's wonky.
Absent pc backups from an earlier time, I'd say the 16's get retired and the 2's put back into service.

Ok thanks. I'm going to try just buying another card from another brand.

What brand were you using?

Have you checked it on Linux? Download a copy to a disk and boot it up. Then pop it into a card reader and see what's there. Windows doesn't recognize ext partitions, so if your card is formatted ext it may not show up.
Just a thought... Merry Christmas.
...Sorry...I was on the phone...

PNY was the brand I was using, however I am now successfully using an 8 gig SanDisk, and it's working now. You see, the reason I asked is because this isn't the first time this has happened in my Dinc, and I've been able to save it in the past, but this time I couldn't, and I was wondering if there's a reason our sd cards kept crashing. Anyway, we'll see if it was just a bad manufacturer. And I would install Ubuntu, however we only have one computer in the house, so I just keep Ubuntu on a flash drive just in case Windows goes kaput, and I need to access files.

And sorry, I hope you have a great Christmas! Thank you for the help.

Hmm.. I had a pny since I got the phone and its held up for me.

I had something like this happen to me on an 8GB card. It could not format inside the phone, and the laptop was not detecting it, infact there was no option to use as disk drive. Finally I fixed it. I had to go into recovery, mounts and storage, mount usb storage. And lo and behold, it showed up on my laptop when I connected it. I now did a FULL FORMAT, not quick format. After this, I put it back in the phone and it's as good as new. Hope this helps someone.

(Q) Weird Sd Glitch

I was downloading a file on my phone and the phone turned off. So I thought okay swap battery and turn on and everything was fine and the file downloaded correctly.
Well I was sitting there and all of sudden phone said Sd Card not inserted? Well it was Inserted so I did the put in put out. And still no go it came up with a blank sd card and says filesystem is not supported? So then it says format it which I tried but it won't work nor will it mount at all. I have a video of it ill upload in a few mins when its done.
If this is the dead Sd card syndrome well is there any way to get data back?

Ext sdcard corruption

So I don't know what's happening but I have a 32gb class 10 micro sd card. And once a week it just goes corrupt and my files are all corrupt. It's seriously getting on my nerves and I don't know what to do. I I've formatted it in the phone and in a pc and it doesn't matter it still happens.

They don't last forever. Have you used that card a lot?

Any ideas? It will just abruptly stop saving pictures to my ext sdcard and when I use root explorer to see why it has changed from read/write to read/only.

Sounds like the card may just be faulty?
I have had one incident with my current SD card recently where it wiped itself but fortunately it hasn't happened again. I have a 32 GB Class 10 also. I have read of other experiences with QC issues with lesser known brands like "Patriot" (my current) or "PNY". I think for my next one I'll spend the extra dough and go Samsung. I hear those are built like tanks

SanDisk are the best. I have a 64GB class 10 microSDXC UHS-1 in mine.

It could be the card itself. Why not try another card and see if it happens on other cards.

Damnit! Not good news for me. I hate that the internal memory is all one partition. This is ridiculous.

SD Card broken?

Dear all,
A few days ago I got my micro sd card from my Samsung s3 taken without disabling them. Since it is no longer recognized by the phone and not the PC. If I plug in the PC takes a long time until I can read the properties. This shows 0Byte. Formatting is not possible => no medium available!
If the card is defective? Or I can somehow bring to life?

Having same issue here. My second card just did it again after a month. Using a sandisk 32gb. I couldn't find a way to fix it.

If you can't format it, and if your computer can't read it there's no way your phone is going to be able to. You took it out without disabling it in your phone first? Bad mistake that feature is there for a reason
Sounds like you may need a new SD card. I have a 32gb sandisk and mine works perfectly :angel::victory::silly:

I didn't remove mine. Mine was in phone when it just stopped working both times.

I am having a similar problem I never removed SD after initial install and starting a few days ago it constantly says SD has unexpectedly been removed and then it mounts and unmounts on its own I tried reformatting it and sometimes it works for a while but eventually goes back to do that.

My SanDisk 32gb card also did this. I've had bad luck with the 32gb card's. I've had great luck with my SanDisk 64gb ultra card, and 16gb card's.

Is everyone had this issue?? Because I had this issue too with my 32 gb card!!
Sent from my SPH-L710 using Tapatalk 2

Had the same issue with my S3.
Turned out that the SD card was dying (the card brand is Team Group), this caused it to be unmounted by itself and then mounted again (sometimes showing notification “sd card removed unexpectedly”), hence triggering the media scanning process.
I created an application to monitor how many times the SD card was removed, and turned out to be unmounted every ~3 mins!!!
I then bought a new Transcend 32GB Class 10 card (made in Korea), and until now, this never happens, no reports from the application whatsoever, and no media process eating my battery.
I just published this app in the play store now, this is the link:

My mom's OG Epic just crapped out.. 16GB Lexar (i think it was) worked fine.... all of a sudden "Damaged SD Card" on top of screen, Put in computer, no dice... Finally got PC to format it, Worked fine in there, Phone still wouldn't read (Formatted different file types each time) tossed in an old 2Gb.. Worked like a true pilsner.. So looks like my computer has 16GB of extra storage now. LOL

External SD card problems

So today i noticed that my SD card was getting really hot and i ended up getting a sd card blank or not formatted message. I installed another card and it works fine. I put the oringinal card in my computer with a card reader and wont even register. Is my SD card fried? Im on FH13 with exynos abuse root. Any help would be appreciated.

Sounds like a dead card. If it is SanDisk, they have a lifetime warranty.
