[SOLVED] Second HD not found anymore

[Atip]

In fluxbox-13.37 suddenly when booting the second hard drive is not found. On that drive I have the swap partion, a back-up partition as well as a testing partition.
If I use live CDs, Salix Fluxbox or Knoppix all partitons on second HD are found either as /deb/sdb* or /media/sdc* respectively.

Could that be a MBR problem and why would it happen?

I am using lilo.

Thanks in advance for an answer to solve.

During Halloween some witch must have played a trick.

/dev/sdb has changed to /dev/sdc.

Changed all in fstab and lilo.conf and back to business.

Device name ordering is not guaranteed to be constant. Especially for devices on external media it can easily change. You can protect youself against this issue by using UUIDs or LABELs (which don't change) where possible. Just replace /dev/sdX with UUID=... or LABEL=... in the fstab. With blkid you can get an overview of the labels/uuids assigned to your devices.

Thanks! Those numbers surely look like witchcraft.
