That's right.

I cant recall the fstab entry but the drive was as Master on the
secondary IDE channel and had only one partition using all diskspace.
In the 4.9 machine the drive is on a DMA-66-Controller. Under Win2000
this is listet as a SCSI-Device. I don't know whether this can be the
problem - I will try to put it again on the IDE-Channel.
