It is a Conner CFP2710 2.1Gb 5400rpm, but the same thing happens with an almost identical setup but with a DEC DSP3210S 2.1 Gb disk. Using SCSI-select I had already reduced the IDs (including 7) down to 5.0Mbs anything higher and it _always_ hangs. > > I could not get the 1st Feb Snapshot to work at all with the scsi disk. > So you are running current from when???

Sorry, I meant that I could not get 950202-SNAP to work at all but 950210-SNAP seems to work fine only if it decides to recognise the disk at boot time. Regards, Jake Dias PC User Group
