The first "badblocks /dev/sda7" run went ahead with no output.

Now running "badblocks -nv /dev/sda7" on this unmounted 20gb partition
and it's taking a little while for the nondestructive read+write test but
so far again no output indicating errors - will post full output shortly.


Yes, I'd come across this one - ran just the plain command first on
hopefully the same disk "areas" which initially had Arch and Fedora
partitions which also exhibited the same problem but I blew them away
and repartitioned/reformatted as ext4 from my ubuntu installation.

I trust (based on the man page) that badblocks re-checks any blocks
marked away by formatting (i didnt select the 'check bad blocks' option
during formatting via gparted) so the problem is not hidden?
