Got CD or DVD drives?
Old HD is probably IDE... you could:
a) find another IDE connector on your
MOBO and connect there
b) disconnect your CD/DVD and use that cable.
should be possible-- and pretty simple to do.
The amount of files... you need
all of those files??
...or does that include everything on the disc?
Once you connect that old HD-- Windows
should automatically detect the drive... as long as you ran Windows on your old machine-- should work like a charm.
The only possible issue... how
new is your new PC ??
Is it still under warranty?
