A couple of assumptions: The old and new hard drives are
both simnple IDE types. (That is, they are not SCSI, or
SATA, or RAID. If it is one of these, pos back with more
info, since they are trickier.)
Verify that the second drive is set to be a "slave", if it
is on the same IDE controller (40 or 80 pin cable) as the
original drive, which I suspect it is. The documentation
that came with the disk should show settings fro master
and slave. If not, go to the drive manufacturer's web
site and look around for info.
Once the drive is connected properly, and had power
connected to it, it should show in the POST, that
monochrome screen you see before windows starts.
Did you prepare the disk after it was physically
installed? In the old days this was done by FDISK and
FORMAT. Today most disks come with friendlier routines on
a floppy or maybe a CDROM. These can also be downloaded
from the disk manufacturer's website.
Or, you can use XP to prepare it. Use the disk management
tool to create one or more paritions, then format each.
If size < 32Gig, you can choose FAT32 or NTFS. If size >
32 Gig, XP will force NTFS. However, third party format
routine, like those from the disk manufactures can do
FAT32 for larger disks.
If nothing else helps, download a set of disk diagnostic
routines form the disk manufacturer. I found the SeaTools
from Seagate to have the ability to test a disk even
before it had paritions or was formated. Maxtor, WD, IBM
all have similar diagnostic routines.
