Bios & Windows reporting wrong disk size after ghosting


I've recently bought a 250Gb hd to replace the old 80Gb that I have on my Dell Inspiron 6400. After ghosting the disk from the 80Gb to the 250Gb, weird thing is happening. The 250Gb is being detected by the BIOS and windows as an 80Gb. Under disk management as well, I can't go beyond this size.

Could someone please tell me what I did wrong and point me to some method of reverting this back. My guess is there's something wrong with the geometry of the drive. But can ghosting a disk overwrite such data???

Thanks for the help

If the BIOS sees omly an 80 gig drive ,either the BIOS  is bad or the disk is bad.

The Ghosting should not affect the way a system BIOS sees the drive.

We're at a hardware talking to hardware level,no OS involved.

Try another system or try to reset the system bios to default.
Hi, You use Disk Management snap-in in Windows XP to perform disk-related tasks, such as creating partitions and volumes, formatting them, and assigning drive letters. On computers running Windows XP, you can also use Disk Management to perform advanced tasks, such as creating and repairing fault tolerant volumes.
Right click "My Computer" -> Manage -> Storage -> Disk Management
Check any unallcated space, and assign them.

If you confirm the HDD detected wrong in BIOS, try update the BIOS.

Hi Punky

thanks for pointing me to the right direction. Indeed the HPA of Dell was the cause and HDAT2 did clear the problem. I now have my 250Gb back. Since you pointed me to the right answer but GaryCase is actually the one who wrote down the answer, I'd like to share the points between you two. Anyone knows if it's possible. I do hope you understand why am doing this...

Anyways thanks for the help. Cheers.
In order to do that, GaryCase must be comment in this thread, otherwise it could be passing points and EE admin will not allow.
There is no problem with the points, I just help and not intend to get any.
