Re: Moving a hard drive w/ a Gateway-installed OEMWindowsXPto a new mobo

And I will jump in here and say with the 2 drive option, I agree entirely
with your segregating stuff John, but would pick to keep data and OS on
separate drives. We are a small company with 10 locations. At this point the
vast majority of our PC's are NOT here at corporate (where we did just
install a Windows file server) so the two drive option with data on D: (as
it works out) has been our "backup". As you note it doesn't protect against
theft, etc. But I think I had seen one "D:" drive act up and the stuff on it
was recoverable in 8 years here but we've lost way too many "C:" drives and
as I have noted before this seems to be a Windows issue (with Knoppix able
to read the drives when Windows can't).

What Scott said was dead-on.

I'll simply add that, for the two-drive scenario, some budget
motherboards come with a single 80-pin cable that's color-keyed to one
of the two on-board IDE plugs.  If that's the case with the mobo you're
moving to then go ahead and use that one for both HDs.

Even if you do a fair bit of disk-to-disk copying you probably won't
notice that much difference in performance.

One point that I didn't really make yesterday was that optical drives
usually talk at a lower DMA Mode than the average hard drive.  You said
your drive was mode 5.  I wouldn't be surprised if the DVD drive was
mode 3 (IIRC the old 33MB/s spec).  They can work on the same cable just
fine but folks always seem to get the best results using separate
cables.  Maybe the IDE controller drops to the least common denominator;
I'm not sure.

BTW, with dual-HDs you can tweak performance a bit.  Set up Windows with
2 swap files, one on each drive (My Computer Properties - Advanced -
Performance - Advanced - Virtual Memory).  Also, consider segregating
the OS + apps to one drive and data to another.  Or OS + data on one and
apps on the other.  Move the browser cache and other temp areas to the
secondary drive.  The concept is to spread the IO across both drives as
in a normal Windows desktop environment the C: drive takes the vast
majority of the work.

And if space permits, institute a batch file to copy important data from
the normal data drive to a backup folder on the other drive.  While it
doesn't protect against theft, fire, etc. it does guard against a drive
failure.
