Hard Drive size mismatch

Irregarless, the true physical size of the drive should not change under the BIOS and should register all available space. The only way this can change is if the drive firmware was overwritten in which the number of heads, sectors per track, and precomp settings were mirrored from the original drive. I've honestly never seen such a problem like yours, but I believe that a low level format may be the only way to fix this.

I suggest the you try the "Questions" forum.

The "Discussion" forum is for matters of general discussion, not specific problems in search of a solution.

Post problems such as this to the "Question" forum, rather than the "Discussion" forum. There are those who specifically seek out problems in need of a solution, and that's where they go to look for such.

Additionally there are the benefits that:

1) The "Questions" forum provides for your feedback, by way of your being able to mark "helpful" responses as such. This does not necessarily mean that a given response contained the complete solution to your problem, but only that it served to guide you toward it. This is intended to serve as an aid to those who may in the future have a problem similar to yours, so that they might have a ready source of reference available, thereby perhaps obviating the need for them to repeat questions previously asked and answered.

2) The revised TR makes it quite difficult to find both "Discussions" and "Questions" that have not had a fairly recent post, owing to some functions comingling them in the listings. By keeping each type in their respective forums, it is easier for all to find what they are looking for.

Have data on the drive that I do not want to lose. However even deleting the partition still shows the drive size incorrect. Need the help of a recovery expert.
