Since IDE and SCSI drives use a TOTALLY different naming scheme under linux
what you are assuming is not your problem...
IDE drives are /dev/hda(x), /dev/hdb(x), etc...
Scsi drives are /dev/sda(x),/dev/sdb(x), etc///
check your /etc/fstab to see what is being mounted where before you do
anything else...
You need to be sure that there is no entry pointing to the second IDE drive
"/dev/hdb(x)". If there is you have a linux partition on it that will have
to be moved or relocated elsewhere before you remove the drive...
Also, if you drives are configured as Master/Slave, remember that you need
to reset BOTH the drives jumpers...
That is Master & Slave jumpers are required for a pair of drives, but NO
jumpers are required for a single drive.
This is probably your problem...
