I just installed a 200 GB Maxtor HD into a Compaq computer as a Slave HD.
The primary 40GB HD that was in there has XP on it.

When I check the properties of the 200 GB HD it only shows up as 127 GB.

Why is this? Does this mean I paid for a 200GB HD and only have 127GB to
use?

It's most likely a BIOS limitation. Get yourself a bios flash update from
your motherboard manufacturer's website, and the problem should vanish. If
it doesn't, try a search on the Maxtor knowledge base (search for 127 GB),
I'm pretty sure they have an article describing this issue in detail.

For hard drive above 128 Gig or so you need two things

(1) motherboard BIOS that can handle it, or PCI adapter card with its own
BIOS (fairly cheap)
(2) SP-1 for XP and something called LBA enabled in XP. Try MS article

I believe Win XP does NOT support drives larger than 127. You should
have gotten a utility flopy or cd with the drive that gets you beyond
that limitation

Thanks for all the advice, I will look into it. We actually just ran
partition magic on it and it is recognizing the full 200GB now, so I am
assuming that it is ok.

Definitely not a limitation of XP :-)

Actually, it IS a limitation in XP, but only pre-SP1. You need SP1
installed to access larger partitions...

Above 127gb requires 48-bit LBA support. Original XP code does not use 48-bit LBA. XP
SP1 adds this support. Install XP SP1.
