The problem is that sraw needs a kernel patch to work (patch is in
/usr/share/doc/scsitools/kpatch.sraw). But I'm afraid it will not
apply cleanly to kernel sources as this patch is really outdated.
Btw, I'm thinking of removing it from scsitools package since it is
not really useful.
Regards.
PS: maybe you could use sg_read/sg_read_long from sg3-utils package
to benchmark your drives.
