Windows only sees about 1/2 of the hard drive

by im2nic2 / May 18, 2005 5:49 AM PDT

I just installed Win XP (what a nightmare), but windows only shows the capacity of the drive as about 130 GB (the capacity is 300 GB). How do I fix this? Right now the hard drive is connected as a SATA 1, but is a SATA 2 (was switched because of problems). If I switch bach to SATA 2 and format from Win XP will it format the whole thing or just the part that windows sees?
Thank you,

That doesn't work with XP.

You need XP SP1 or later to accomplish this. The noted site documents this issue in deep detail.

Hard drive size limit.....addendum
by John Bee / May 19, 2005 11:02 PM PDT

By the way.....don't forget to update to SP2....you need the update to allow XP to manage more than 127. It can be limited by either your bios or your XP. Either way, you might need to update BOTH! If you call your hard drive manufacturer's tech line, they'll walk you through it......have fun!!

Hard drive size limit
by John Bee / May 19, 2005 10:51 PM PDT

You're problem isn't with you're XP. It's your computer's bios that limits the hard drive size that is recognized to only 127 gig. Check with your board manufacturer's website and, if you have big balls, flash the bios with the latest update.....then it will read all your drive regardless of how big it is or what OS you're using. I just went through the same thing and opted to install a seperate Siig SATA PCI card instead of taking a chance on flashing my chip. Either way, don't blame your XP....having used all of Microsoft's OSs, XP is still yhe most user friendly of the bunch as far as I'm concerned!

Good luck!!

Windows XP Professional

I recently hooked up 2 SATA 250GB Caviar Drive's.

I used my on board Raid program to setup the Raid 0+2. I did have to make a Bootdisk for the Raid driver's.
Windows XP shows that I have about a 476GB HD.

So, not sure where the problem lies with your particular setup.

Have you installed the proper drivers and, have you changed the boot order in the BIOS settings?

It is not Windows XP or any Windows, but I am sure that it is your motherboard who needs upgrade.

Is the 300 gig your main system drive or a storage drive
by toughschell / May 20, 2005 4:14 AM PDT

if the drive is bigger than 137 gigs, you have to right click the My computer icon and click manage. once the window pops up, click the Disk Management link under the Storage tree. You should see all you hard drives and CD drives listed, you should also see the 300 gig in there as a dynamic disk, right click that and format it. then go from there.
