Re: [Gumstix-users] micro SD flash card does not work in Verdex pro

[jdoutt <jd...@wh...>]

Update:  it does work if card is in at boot time.  But if I unmount it,
remove it, and reinsert it the system does not recognize it.  And if I try
to remount it using  "mount    /dev/mmcblk0p1    /media/card/"

I get a lot of errors such as

mmcblk0: error 1 sending read/write command
end_request: I/O error, dev mmcblk0, sector 137
Buffer I/O error on device mmcblk0p1, logical block 0
mmcblk0: error 1 sending read/write command
end_request: I/O error, dev mmcblk0, sector 138
Buffer I/O error on device mmcblk0p1, logical

Does it have to be reformatted to get it to work properly?  Also, what type
of filesystem is recommended for compact flash cards:  FAT32, ext2, ext3
......?
