This is what i get when trying to use the -b option with badblocks # badblocks -b 4 /dev/hdb1 Floating point exception By the way, this happens with other numbers too. Without the -b option the program works. Reproducible: Always Steps to Reproduce: 1. badblocks -b 4 /dev/hdxy 2. 3. Actual Results: The program triggered a floating point exception. Expected Results: Check a partition for bad blocks with a given blocksize.

you didnt say what version of e2fsprogs you're using :P if it isnt 1.37-r1, then please try upgrading
Well, i'm using 1.35-r1 at the moment, which is the latest version in the stable branch for x86. By the way - i found out that I maybe should have written '-b 4096' instead of '-b 4'. With 1.37-r1 i get 'badblocks: File too large while trying to determine device size' which seems to be more reasonable.
