I[m posting this question only after searching Google and the MS
Knowledge Base. Thank you in advance for responding to this question.

I have a Win 2000 system, self-assembled. Works great. Drive
subsystem is SCSI based, using a Tekram 3900 U3W SCSI host adapter. I
normally have three wide SCSI drives attached, either 36 or 72 GB
each.

Today, I tried to attach two new SCSI drives to my system by removing
the two non-boot drives. I could see the newly attached drives in
Device Manager, but _not_ in Explorer. The drives were also not
visible in the Disk Management folder within Computer Management
(Administrative Tasks cpl.), even though I would expect to see these
drives even if they were not formatted.

What is my next step?

Howdy,

I hesitate to ask, but...

Is there any possibility that in Explorer | Tools | Folder
Options | View you have Show Hidden Files turned OFF?

HTH,

This might happen if the disk does not spin up or is unreadable (the MBR).
You should verify the drives from SCSI setup or Bart's scsitool from a
floppy.

Hi,
Took care of I/O cable of termination properly(very important)? Checked
in SCSI BIOS?
I run all SCSI W2K as well.

hi ,

are any partitions on this disks ? let me guess : extended file systems
?

if you insert a blank disk ( usually ) you can work in one straight line
til the formatted partition .

No. I also mentioned that the Storage Management system tools can't
see the drives either.

Thanks. That suggestion seems right on target. Time for another
visit to Bart L.'s web site.

This is slightly off topic, but what does this guy do for a living?
He seems to have put enormous amounts of time into his web site. It's
an amazing resource.

Tony, thanks. I mentioned above that I removed the two non-boot
drives, and replaced them with the new drives. Unless there is some
really weird mojo with the cables, then I have to assume that there
are no termination issues. My Tekram controller detects the drives
and their firmware rev. levels. It's Windows that is the problem.

Wolffang,

What do you mean by "Insert a blank disk?" Do you mean a floppy disk?
What do you mean by "work in one straight line?"

hi uppers ,

no floppy - i ment a brandnew hdd without any partition or else on it .
load w2k , go to "drive management" , write a signature to the new disks
, format them , eventually turn them into basic ( instead of dynamic )
drives . this can all be done in one line .

excuse my poor english please .

Hi,
Some times drive has id. jumpers and termination jumper. If the drives
are in the middle of chain, termination is of course not needed.
