# badblocks /dev/hdc8 -b 4096 # dmesg -c invalidate: busy buffer # badblocks /dev/hdc8 979932 # dmesg invalidate: busy buffer attempt to access beyond end of device 16:08: rw=0, want=979936, limit=979933 attempt to access beyond end of device 16:08: rw=0, want=979936, limit=979933 So using the -b option has the side-effect of not accessing the partition beyond its end? I'm running a vanilla 2.4.20 kernel, actually it's the kernels task to refuse those accesses, isn't it? However, what I'm missing in the FAQ, is a short note about _why_ one should use the -b option, so no worries arise when getting bad blocks without it. Thanks Marius
