drive functions fine in laptop, can only boot into safe mode though. The usb
case is powered by default from the usb port, however there is a power input
on the case that you can attach to another usb port to increase the power.
Have attached power, still no change.

Nell:
If I correctly understand your query, you *were* having problems with that
Toshiba drive when it was installed as a working HD in your laptop in that
it wouldn't boot to a Desktop and you could only boot into Safe mode. So
there's a problem with that drive notwithstanding the USB issue. Its failure
to properly boot most likely explains your present problem using that drive
as a USB external HD.
I'm assuming from your query that there's no data on that Toshiba drive that
you want (or need) to access. Assuming that's so, then perhaps the simplest
approach would be to see if you could re:format the disk (using Disk
Management) while it's connected as an internal HD in your desktop computer.
Since it's a 2 1/2" drive you'll need a 2 1/2" to 3 1/2" adapter to do this.
Of course if you can accomplish the formatting while the drive is installed
in its USB enclosure, then obviously that would be the way to go.
If it's not possible to use your desktop's DM utility per the above, another
possible scenario would be to reinstall the drive back into your laptop and
format it (FAT32) with your Win9x/Me Startup floppy disk. (I'm assuming you
were previously running Win9x/Me in your laptop).
The obvious point in all this is to clear what possibly is a corrupt system
files situation that prevents the drive from being properly recognized by
your desktop's computer OS.
It (nearly) goes without saying that all this assumes that the Toshiba drive
is mechanically/electronically sound and that there's no problem involving
the USB enclosure. I don't get the impression from your posting that there
may be a hardware defect involved here, but it may be wise to run a
diagnostic on the drive.
