Hmmmm.... I wonder whether it would be useful for mke2fs etc. to write to sector n-1 and n-2 (where there are n sectors on the disk) and read the sectors back to check the last sectors on the disk actually work. This would detect bad extents very easily and quickly. I am sure there are innocent causes of this problem on other media (i.e. it would be useful beyond fake USB drives) Alex ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
