Hi, all

when I plugin a 2G usb to embeded linux on my board, it will occur errors:

FAT: Directory bread(block 1968) failed
FAT: Directory bread(block 1969) failed
FAT: Directory bread(block 1970) failed
FAT: Directory bread(block 1971) failed
FAT: Directory bread(block 1972) failed

FAT: Directory bread(block 272965) failed
FAT: Directory bread(block 272966) failed
FAT: Directory bread(block 272967) failed

what's wrong with my usb? other usb is ok.

Run a 'fsck.vfat -nVv' on the partition and show us what it returns?

I found many chk-suffix file in found.000 directory in my usb; so I "rm -rf" to delete that directory; these errors are not come out again from then; I know this is not the good solution. how to recur these errors to test it? I don't know.

this is message from "fsck.vfat -nVv" on my usb partition.

thanks

File system seems clean now. I'd say just be content with that.

favora000,

I think you accidentally clicked the "Report" button instead of the "Quote" button when you tried to thank unSpawn.
