Hello Marc

The Drive is not available in /proc/scsi/scsi

it should be /dev/sdb

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: IBM Model: DPES-31080 Rev: S31K
  Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 04 Lun: 00

  Vendor: TOSHIBA Model: CD-ROM XM-5401TA Rev: 3605
  Type: CD-ROM ANSI SCSI revision: 02

The output of 'dmesg' is absolutly confusing as it shows that it found the
drive somehow
but then it gets completly confused! Please look at my remarks!

/dev/sdb cannot be accessed (as it could before installation of Windows
2000!!) (Not from hdparm or fdisk!)

I am thinking about a low level format. But I still don't want to do it
because somebody
wants to detect something here.

??!!!

I can access the drive with W2K or W98 no problem (with ext2explorer's all
the partitions
with files are there!!!
