WDC 320 AAKS missing a lot of space?

[noobwants2learn]

Hi all,

I was installing Fedora Linux when it crashed and next my Windows partitions were missing.
After restarting the PC, I found that the harddisk size was changed to only 128 Gbytes. Some partitions were missing.
When I tried HDDGuru's Low Level Format Tool, it only detected 128 Gbytes, so did BIOS. BIOS no longer detected the 320 Gbyte HDD; the LBA option was missing, leaving Large and Normal modes only.

When I repartitioned the HDD using GParted, it detected the 320 Gbyte space and I successfully created some partitions (without any error messages). But when I got back logging into Windows, it detected the harddisk as 128 Gbytes in size, again.

So, what happened to my HDD?
How do I recover it to get 320 Gbytes HDD space again?

Thanks in advance,
Joss

Anyone, please?

Typically when you can only see 128GB of space on the hard disk it is down to the BIOS on the computer you are fitting it to. Have you tried accessing the drive on a usb interface on a friend's computer?

Sorry for long delay to reply this.
I just get a chance to borrow a friend's computer to check my hard disk, and amazing, it IS normal. It's space is detected as 320 Gb. I have no errors in repartitioning and reformatting the HDD.

I think it's a BIOS problem. Thanks again John, I appreciate your help so much!
