I'm with Mick. Look in the BIOS settings first. It's quite possible
that one of the drives is turned off in the BIOS. Try looking in the
BIOS when only one drive is connected.
I've never tried mixing different speed drives. Couldn't you put them
on different connectors?
BTW I suspect you could get bigger drives by asking nicely on
I am the Group Owner of an Independant Local Group and that is where the
parts for the construction came from.
In Bios, both drives are seen. In Device Manager both drives are seen. In
Disc Cleanup only the partioned C & D drive are seen.
There has to be an answer somewhere.
My thanks to everyone for their advice. I now have the new drive working. I
never knew about "diskmgmt.msc". This command worked a treat.
I have been building computers now for about 5 years from parts donated and
have never come accross this problem before. I wonder if it is something to
do with the computer itself. It is a TIME computer with a KM400 motherboard.
Thanks again for the invaluable help.
You can also get to it by right clicking on my computer and selecting
"Manage" - it will be one of the later entries in the list of tools.
The early mounting of drive partitions can be done by the BIOS, but
different ones have different capabilities. Many only recognise DOS
style capabilities (i.e. only one primary partition, and then an
extended partition with as many logical drives as you want etc). Windows
(from 2K onwards) however is far more capable in that respect, and can
handle lots of drive arrangements that the BIOS can't hack, like
multiple primary partitions on the same drive, drives without drive
letters, and drives grafted into the directory structure of other drives
(*nix style) etc.
It's not new - in the DOS days you would have used FDISK and FORMAT. In
general, to install a hard drive under Windows (or any OS, really), you
need to do three things:
Physically install and connect the drive, including setting up the BIOS
Partition the drive.
Format the new partition.
If you have a drive that's already been partitioned and formatted, then
you may be able to skip the last two steps - but if it's completely
blank, or the file system is inappropriate for the system you're adding
it to, then you'll need to do them.
