As I said that eSATA case / cabling turned out to be quite flaky later on. But on the third try I completely replaced it. Only thing that is unchanged is the 1 GB eSATA drive. But then on the third case I did not see *any* errors in the log at all until I disconnected both drives and removed the PCMCIA eSATA controller. As of my knowing it should all be eSATA cables. I used the cables that where delivered with the eSATA cases. > #2 the Cardbus Sil3512 controller somehow got stuck asserting an > interrupt that wasn't cleared. What could be the reason for that one? Could it be that the PCMCIA card had to many plug / unplug cycles. Contacts look fine tough. > Needs the Sil3512 person to look at it.

Ok, if I can help with some test I try my best to take to time for it. I will wait for further instructions / questions. For now I just assume that the data in the backup is okay and just use rsync periodically to update the backup - that seems to work. The data is a bit less important than the one on the internal drive so I hope I get away with this ;) Ciao, -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7
