sd card problems

[lvaldez8446]

sorry if this has been posted somewhere else but since I installed miui 1.10.14 and 1.10.21 my external sd card is not being recognized for some weird reason. i keep getting a notification that my sd card my be damaged or that it has been removed which i always keep inside the phone. i have to keep mounting sd card through recovery or through settings. im new to miui so i was wondering what i can do to fix this. ive used several different roms, paragon rc6 being my fav so far. once i saw miui i fell in love...haha. if this a bug and cannot be fixed then i have no choice to have to flash back to another rom which reads my internal and external sd cards. thanks in advance for any help i can you guys gimme.

have u tried formatting the card from the phone and see if that fix it?

Yes but it doesn't recognize my external SD card

If this is still a problem I would recommend taking your sdcard out of your phone and connecting it to your computer through a card reader and reformatting it there. The best way to do this is with gparted but windows will work fine

Just found out that this rom doesn't support 32 gb external SD cards

Have same problem with my 8gb external sd card and also my 16gb. Doesn't read none of them. Any Solutions???

My 8GB worked fine since the day I switched from the 4GB. Getting a "Scan the partition" when I connect to a Windows, but that's SD-card related, has nothing to do with the ROM.

Greetings. I have similar problem with my 8 gb sandisk card. This card worked well for about 6 monts on various ROMs. It acts like this only on cm7/MIUI. Here is the output of logcat at the time when i insert sdcard:

What I tried:
1. Mount it via adb shell
mount -t vfat /dev/block/vold/179:9 /mnt/sdcard/external_sd
mount: mounting /dev/block/vold/179:9 on /mnt/sdcard/external_sd failed: I/O error

2. As far as i know lagfix is based on file system conversion from rfs to ext4, so the kernel support it. So I just formatted my sd card in ext4 using Minitool Partition Wizard( can be found on http://forum.xda-developers.com/show....php?t=1072369). I got similar output with logcat to the one above.
The system did not mounted it and I did it myself:

mount -t ext4 /dev/block/vold/179:9 /mnt/sdcard/external_sd
chmod 777 /mnt/sdcard/external_sd

And it Worked! I can access my sd card and have r\w permissions!(to be correct every program on your phone has r\w permissions to external sd)

mount | grep 179
/dev/block/vold/179:1 on /mnt/sdcard type vfat (rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000, gid=1015,fmask=0602,dmask=0602,allow_utime=0020,co depage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro)
/dev/block/vold/179:9 on /mnt/sdcard/external_sd type ext4 (rw,relatime,barrier=1,data=ordered)

Now all that need to be done is to create simple script to mount external sd at boot, and find a way to mount this card on windows machines. I will try to find a solution tomorrow.

Actually I'm a Fascinate user, but I have found that on some (if not all) Galaxy S phones 32gb cards don't seem to be working. It is a ROM problem as this seems to be the case with MTD based ROMS. I don't know if this will ever be addressed.
