You might be seeing the same problem as what I reported about a year ago: reading by anything larger than 512 B blocks is "unreliable" - gives junk. But, IIRC, I have seen it even with smallish partitions (do not remember the details - it should be on Usenet). E.g., my Perl module for post-mortems on FAT reads by 512 B when run on OS/2 (of course, this is painfully slow). But at least I did not see any OTHER problem with my test cases... Ilya
