What do you mean by "media drive"? All HDs (et al) are "media" drives.

I really do not know what is causing your problem but I can only suggest
the following from what you wrote above (and earlier).
1. When you were using Linux the system suddenly froze on you (a few
times I believe). What I suspect is that there is a corruption on your
Linux file system (OR it could be bad RAM) which caused the initial
crash which would have corrupted your file system after which subsequent
freezes only further corrupted the file system. What you need to do is
to make sure that the file system is "clean" and do this you need to run
e2fsck [WITHOUT the '-p' parameter] on the partition which has your
system on it. If you don't know how to run e2fsck then ask. BTW, which
file system is being used on your Linux system- ext2, ext3,.....?
2. Re the difference in the times between Premier you installed on XP
(which XP- Professional, Home? doesn't matter really) and Linux. Did you
defragment Windows before you started the job and before doing so did
you get rid of all the crud which Windows creates on its disc space?
Other thing, XP only supports USB#1 and cannot handle USB#2 unless it
has been upgraded to at least SP2. Which USB does your external USB HD
have - USB#2 (or maybe even USB#3 which is now all the rage)?
It is in the nature of things that every time you try to avoid one danger you run into another.
