Howdy, I have a 'puter that has a SCSI hard drive and CD=ROM. I have a
couple IDE hard drives that I would like to check out and see if they
are any good. Both of my IDE channels are free on the mother board.
What I need to know is if I can just plug the hard drives into the IDE
channel and look at them and run scandisk and format on them with out
screwing up the SCSI setup? The SCSI is run from a PCI card, not the
motherboard. Running Win98. What would I have to do to do this?
Thanks!

well not to say something won't happen, but I've that many times without a
hitch.

Depends on your MoBo BIOS. If it allows SCSI before IDE boot order, there
should be no problem. If not, it may depend if there are bootable
partitions on the IDE HDs. If it will boot from SCSI with a nonbootable IDE
drive connected, you're home free -- just repartition and reformat as you
like, and do NOT make any of the IDE partitions active.

If you can't do that, connect the IDE HDs, boot from a Win98 floppy, and
partition them there. MAKE SURE you partition the correct HDs! Then
attempt a reboot from SCSI after the old partitions are removed, and
partition/format.

If you can set your bios to boot from the scsi first in boot order, then you
should be ok in what you want to do. Otherwise the ide drives may cause an
issue with your system.

there is however another alternative, you can get a scsi-ide bridge adapter
and run it as a scsi hard drive.

Just connect the HDs to the IDE ports, provided that they're declared as
Master and Slave if they're on the same cable.
Don't modify anything in the BIOS. You're booting on the SCSI and you'll
continue to do so (at least at DOS level !). Normally, starting the
computer, next time, when the Hds will be connected shouldn't change
anything. However if you have several letters assigned to different
partitions and if you have primary active partitions declared on your IDEs,
the letter order will be changed. Let assume Windows is installed on the D:
or E: SCSI logical unit, SCSI disk being alone, you'll probably not be able
to boot with the IDEs because the IDE's primary partition letters will steal
the SCSI's D: and E: letters. The following SCSI partitions will come after
and the rest of the logical IDE partitions will come at the end.

Example:
SCSI alone:
C: SCSI boot, D: SCSi utilities, E: SCSI Windows 2000, F: applications # 1,
G: your own productions #1
C is the primary active partition ==> bootable
D, E, F; G are logical disks installed on the extended partition
Windows will start on E:

IDE1 alone:
C: IDE1 boot and Windows 98, D: applications # 2, E: your own productions #2
C: is the IDE1 primary active partition ==> bootable
D, E, are logical disks installed on the extended partition
Windows will start on C:

IDE2 alone:
C: IDE2 boot and Windows 2000, D: applications #3, E: your own productions
#3
C: is the IDE2 primary active partition ==> bootable
D, E, are logical disks installed on the extended partition
Windows will start on C:


SCSI + IDE1 only:
C: SCSI boot, D: IDE1 boot and Windows 98, E: SCSi utilities, F: SCSI
Windows 2000, G: applications # 1, H: your own productions #1, I:
applications # 2, J: your own productions #2
Windows won't start because E: contains utilities

SCSI + IDE1 + IDE2:
C: SCSI boot, D: IDE1 boot and Windows 98, E: IDE2 boot and Windows 2000, F:
SCSi utilities, G: SCSI Windows 2000, H: applications # 1, I: your own
productions #1, J: applications # 2, K: your own productions #2, L:
applications #3, M your own productions #3
It will probably boot on the Windowz 2000 version installed on the IDE2 HD.
I say "probably" because the DOS configuration files may call pieces of
software not present on the old E: (disk drivers, memory management, ...).



The best way to prevent such a situation is to boot on a floppy disk, then
run partition magic (ver. 8 if you have disks larger than 40 GB), declare
the primary partitions as hidden on all the disks except SCSI HDs and
reboot.
The next time, all the SCSI disks' letters will remain in the places they
nominally have, then the letters of the logic disks of the extended
partition of the IDE1 will appear followed by the letters of the IDE2
mounted as slave or connected to the secondary IDE port.
The draw back is that you loose the space of the IDE primary partitions.
However if nothing of valuable is on them but boots and windows, with
Partition Magic, you'll be allowed to reduce these partitions to 7.8 MB FAT
16. The rest can be one logical disk or more within the extended partition

I've five disks SCSI's IDE's & one SATA. They're arranged following what I
said. I can add or remove disks with diferent number of logical
disks/partitions, nothing wrong appears because the entire system is
installed on the first IDE disk. I have also a full copy of the IDE bootable
disk, hidden on the second IDE, waiting for activation in case of major
problem. Just to swap the disks and go ahead !

May be a little confusing ! The rule is that primary partitions appear
first, followed by the letters of the bootable disk then by the most ranked
disk ie the primary master finally by the lower priority one the secondary
slave.

Just put both on the secondary IDE as master/slave. If one of them is a
bootable drive, just make it the slave to be safe. Its highly unlikely
these drives will have any affect on the scsi boot. Make sure they are
recognized in your MB BIOS, that's a good "first check" on their
condition/usability

If there is an old or unused OS on one of the HD's then you will have
trouble with 98 but no probs doing the same with XP.
