external SCSI cd-rom tower

By pfitzner.gr ·
Just wondering if you may be able to make a suggestion to where I went awry here

I could see all 7 of the external scsi
cd-rom's, no problems before installing an extra 20 gig hdd (which became drive f:).
Now when the computer starts up it appears that it sees the external scsi hardware as they all light up and blink etc but they will not appear in my computer with the other drives.
If this information is of any help,
Machine type IBM NetVista Model 6578-TAA
XP Proffessional operating system
Adaptec AHA-2930cu SCSI pci card
At start up will either get
"time-out failure during inquiry command"
"rescanning for scsi devices"
And then "no scsi device found"
And continues to boot into windows normally.
If I go to control panel- computer management- storage- disk management- action- rescan disks,
All the scsi CD-ROM'S appear to be scanned, ( I can see the lights flashing on them as it is scanning)
they just do not show anywhere,
The same if I go device manager-DVD/cd rom drives-scan for hardware changes.
Like the machine Knows they're there.. just I am unable to see them .. Hmm ,
What does one need to do to be able to see the scsi cd-rom's ??
It is probably not worth the effort & time I spending on it , just 2 of the cd-rom's I would like to keep and use as one of them is a cd writer and works extremely well,this tower cd-rom tower was originally connected to an Old Pentium 2 IBM Netfinity 3500 scsi server and everything works fine when connected there .. just netfinity is big and niosy under desk at home :-)

SCSI is so picky and some times down right flaky. Double check your addresses and i usually place the hard drives first in the sequence and the the CD/ROM's. Bell & Howell uses the same setup for a parts look-up system they sold to auto dealers.

Have you looked in disk management? Maybe they need to be reassigned drive letters.
Admin tools -- comp management -- disk management.

Also, check the bios and scan for the devices, see if there is a SCSI ID issue.
maybe something came unplugged partially causing the issue. check for loose cables.

Thanks Guys - a little closer, i am now at
Device manager- View- Show Hidden Devices- and hello, there they are :-)
But Greyed & telling me with a r click -properties- "this hardware device is not connected to the computer" (code 45)
and they most certianly are, because when - Scan for Hardware Changes " is run they are scanned ..
so the cable & pci card have to be ok .. Hmm
