All SD cards have a class. Class 2 to 10 ten being The best .the better the class The better the file transfer. Cause it sounds like you got a bad download. also did you wipe cache dalvic cache format system before updating to cm7

This was happening on stock too.

Then I would say flash back to stock and send it in for warranty

Lol I'm glad someone else finally actually posted something helpful for him. Timothy was like an IT guy "did you try turning it off and on?" No offense.

THANK YOU! I'll try that when he's not using it. However how would the SD card cause his problem?

I fought with this issue for a long time, ended up using EaglesBlood's ROM and it didn't have the same issue. It's also not happening with EB's ICS ROM. Just in case the SD card isn't the problem...

The SD card could have a bad file on it or if its not a higher class it could lose some important files when transfering

SD was not the issue, I'll look into EaglesBlood's ROM now

The same thing started happening with my phone recently. It stays black when trying to wake the device and stays black during a phone call. It's only happening sporadically though. Kind of like a bratty child, only working when it wants to.
I've had this phone for about three months now but I rooted this device the same day it came out the box. I'm running CM7.1.01 Stable.
My SD card is a 32GB class 10, but I don't see how this could be an issue with the ROM.
When it happens and it won't respond to power button or volume key I just yank the battery and reboot..
Could it be a hardware issue?

I upgraded to supercm7 from android 2.3.3. Cleaned User Data, Dalvick Cash and Cash before the upgrade then flashed rom with the Supercm7. All functions seems to work. However I lost 32gb of my external SD since the external SD is showing now as \mnt\emmc. Is there any way to make the \mnt\emmc become the external_SD.
Unfortunately currently I have music, pictures and videos that were on this SD card but no longer are seen by any of the applications that saw these files in previous android OS.
Please help if you know how to fix this.

I just seen a thread on that the other day..hold on a bit..I will do some searching:!

[Q] SD Card Settings

What is the best way to format your SD card for these blazes? I see a lot of mixed results when Google-ing.
I need to wipe pretty much everything, I know I have gremlins.

Well it was mentioned by a Dev that there might be one soon
Don't ask for eta, but he mentioned it so we can hope >.<

I did mine from my computer. Although someone told me this wasn't the best way. But no problems so far

I always format through CWM. I don't know which way is best though.

i'm using liquidbeats
had upgraded the baseband and flashed liquidbeats via CWM and had problems with no service but reflashed stock rom and baseband,that resolved the no service problems but since then the phone aint been picking up my sd card,
the card works in my fiancee's sgs2
and no other card works in the o3d
never had this problem with my hero when i rooted that
only other thing i have done that might cause this is the fact i used Rom manager to install CWM....
seen threads about some other devices that have had the same issues.

Anyone have any ideas in fixing this?

Anyone know how to fix the sdcard security issue?

Ever since I upgraded from cm10 to the jellywiz rom I have been getting "Cannot access external sdcard for security reasons." I paraphrased because I can't remember the exact wording. Anyways anyone know why that is or if there is a workaround for it? I have tried multiple ROMs and even changed the kernel but it didn't work. I wanted to try to go back to ICS then back to another jellybean build but I am not sure how to do that. I hear it has bricked a lot of phones. Has anyone had this same issue and somehow fixed it? I miss my music.

So you can't access things in your sd card? I get the same error in boot, but then still have full access to my

Yeah it won't even recognize it when I plug my phone in my computer. It will recognize that there is one on my device but it says "blank sdcard or unsupported file system" It is the correct file system and it worked in ICS and CM10.

I kinda feel like I may need to go back to ICS to try to fix this anyone know a good way to do that?

Sounds like you figured it out. Now have you tried formatting the card to see if it can be saved. Obviously after you back everything up, since your computer reads it.
