    Prior to changing my OS from Windows 2000 Server to Windows ME (software incapibility issues), I had 2 internal HDD. Now, only one is visible.

    I have Adaptec Ultra 160 SCSI controllers

    I have used the SCSISelect software (option on bootup), and found the following:
    There are Channels A & B. When I run the utility on Channel A, these are my findings:
    AIC-7899 at Bus: 01h; Device: 02h; Channel A
    SCSI ID #7: Adaptec AIC-7899
    Host Adapter SCSI ID 7
    SCSI Parity Checking enabled
    Host Adapter SCSI Termination enabled
    BIOS Info:

    IRQ Channel 05
    I/O Port DC00h
    SCSI Termination level 0

    When I run the utility on Channel B, these are my findings:
    AIC-7899 at Bus: 01h; Device: 02h; Channel B
    SCSI ID #6: Adaptec AIC-7899
    Host Adapter SCSI ID 6
    SCSI Parity Checking enabled
    Host Adapter SCSI Termination enabled
    BIOS Info:

    IRQ Channel 11
    I/O Port D800h
    SCSI Termination level 0

    Can anyone help me configure these settings to utilize the send HDD?

    So which channel are the SCSI drives hooked to?? You probably had one of the drives set up under windows 2000 server as a NTFS file system which windows ME doesn't understand. Probably fdisking a drive to FAT32 and reformatting the second disk will fix it.

    The one that is functioning is on Channel A. The other, presumably, is on B. I have not looked "under the hood".

    You need to look. Usually SCSI drives are hooked up all on one line to one channel. You can also see if both drives spin up ok.
