Hi Alex
I have tested with raidtools 0.90 also and had a similar problem. Also
there were a lot of similar questions on the list in the past.
Try to make a new ext2-fs on the disk (maybe on another system) and connect
it again; as far as I remember, the raidtools mark a bad disk and recognize
it as a bad disk until it has changed (what would be done by a mke2fs ...).
Has something to do with the superblock, but there are so many mails coming
in... I can't find the original ones.
Greetings, Dietmar
