Damaged/Blank SD card CM7/MIUI

---

I've been having ongoing problems with my SD card in both MIUI and CM7. Basically, sometimes my card will mount and sometimes it won't. When I try to mount it, it sometimes says "damaged card" or "blank card" There's no consistent behavior. Sometimes it loads up fine on reboot, sometimes it works fine if I eject and reinsert it or unmount/mount it, but sometimes not. I've tried two different cards - one a sandisk 32gb class4, one a sandisk 2gb class4. I've tried reformatting the cards both on the phone and on the computer, using windows standard format and also the sdformatter program. I've loaded each ROM several times, ODINed back to stock, ext4 formatter, kernel cleaner; tried different kernels, different radios, different cards.

The cards I'm convinced are not the problem, because they work fine on the computer and also on my phone using different ROMs. I've seen people come up with this problem here and there, but not found a reliable fix. Every thing I've seen recommended I've tried, but nothing lasts. Sometimes things will work fine for a couple of days, then I'll start having problems again.

bump - anybody have any input on this problem?

just flashed cm7. My sdcard works fine on cm6.
the other weird, app2sd is just fine, every app on that partition working, except accessing sdcard.
sdcard also can mount on recovery using, as well as mount mass storage via recovery (mass storage failed on OS)

The only problems I've ever seen with sd cards is on ec09 but not cm7 or miui.. based on what you describe...I would think its a hardware issue with your phone not the rom, not the kernel, nor the sd card itself, have you tried pulling the battery, removing the sd card and cleaning the contacts on your phone with some rubbing alcohol on a q-tip..do the same to the card or you can use a pencil eraser for the card...is it possible you could have tried to insert a card the wrong way or a little crooked? I'm just brain storming for ya cause I'm not sure on a definite fix.
If you can, I would back up everything on your card while its still usable just in case its crapping out on ya

Thanks. I haven't tried that, but not sure how it could be a hw issue since the card works just fine on other ROMs on the same phone. Never had any SD card issues of any kind until I started messing with these GB ROMs. I will try, though.

I'm really thinking of going back to a froyo rom for now because I need stability. But this is such an intermittent/rarely reported issue that I don't think anybody's really working on it. I don't know that it will ever get fixed, in other words. Oh, well.

Well, I've given up on cm7 for now. I've gone back to ed05, trying the powerwashed ROM for now. Got to get some stability out of my phone, and unfortunately, I'm coming up with nothing from cm7. Maybe if there's a big update or something I'll have time to play with it again.

solved on CM-7.1-Pre
tried installing other rom base on CM-7.1-Pre and it work like a charm.
still curious if i have bad sdcard, tried back to previous ROM, and.......... the problem persist there.
so I decide to try dualboot.....

All my sd card mount issues are usually solved with a battery pull

I also have problems with my SD card. I can't partition mine. I more or less bricked mine about a month ago flashing a voodoo kernal, or not voodoo (I can't figure the whole thing out anyway) where it wasn't supposed to be (I think....), and followed Dale V's instructions on unbricking EXACTLY. I've now gone clear back to Eclair 4 times, ODIN'D AND HEIMDAL'D each and every time I've gone back to stock, AND I've used different links to different DL09, DL01, ED01, EB01, ED04, and on, and on, and on...and every time, my SD card partitions perfectly, I think (at least I don't get the E: can't format, file doesn't exist crap when I try to wipe dalvik cache, and only dalvik cache). As soon as I flash 7/17 CM7, the updates, gapps, glitch kernel, I have no partition. I can see the partition with file managers, but there's nothing there.

So, I totally feel your pain.

And while i'm here, why do I have a .apk called FOTAKILL in my files????

Peace!!

CM7.1 pre is an older build, correct? Where can I find it? Am I understanding that you install this one first and upgrade from there, or just leave it at this build? Anything else I should know if I want to try this out?
