OK here's my findings so far.
I've run scandisk on ...
- an ext2 RAID1 volume (formatted with 1.06) - failure
- an ext2 standard volume (formatted with 1.08) - successful
- an ext3 standard volume (formatted with 1.08) - successful
- an ext3 RAID1 volume (formatted with 1.08) - failure
Out of curiosity what exactly is scan disk supposed to do? Presumaby find and fix errors.
What does the failure mean? That it did not find errors, that it found errors and did not fix them or that it did not run?
What does successful mean? That it did not find errors or that it found errors and fixed them?
It would be nice to have a little more verbose output messages - along the lines of - no errors found, nn errors found, nn errors fixed, aa errors found, bb crosslinked blocks, cc orphan blocks, dd fragments - etc., etc., etc..
