I have purchased a new computer with a 250GB SATA disk. After that I installed there my old 120GB IDE disk.
However, when I started to format my new disk, I discovered that its size is recognized as 130GB only. I checked the disk part number and indeed the disk must be 250GB.

Any ideas?
Thanks,
Ilia

Hi,

Did you solve the problem? If so, how please.

We have a SATA Pentium 4 dual core running Windows 2000. The boot disk was cloned from the old IDE 60G onto a SATA 160G and this disk appears correct in Win 2000 and Win XP which has been installed on the second disk, which is a SATA 500G. Booting the XP disk (SP1), both disks show up with their correct sizes. However, booting the Win 2000 disk (SP4 + Rollup 1) the boot disk shows as a 160G drive correctly, but the 500G (which contains a running copy of XP) shows up as 128G and unformatted.

Regards
Richard

also write a few more details, what Os r u using?
Whats your motherboard model? Its possible that your system in limited to 130GB

No limitation on motherbaord, otherwise XP would also have size errors.

Found a file 'EnableBigLba.exe' which solves the problem. It boils down to a registry tweak done by the programme.

This presupposes that the motherboard shows the correct size (this one did).
