Okay I won't go into long detail about the history. Suffice it to say A partition failure, loss and miraculous restoration of my HD has left me with a few odd problems. The first being rather curious in that the capacity of the hard drive is being misreported.

Now I've checked several forums on size misreporting and strangely they all concern the capacity being reported as less than the expected size...my case is the the extreme opposite. While the partition that was restored is the same 233gb... (the hdd itself is a 250gb) The size being reported for the capacity is in Petabytes.

My first hint it was when I notice the bios flagged the drive as LRG (large) as opposed to the normal LBA. Now this doesn't seem to be causing any issue but I would like to fix this issue.. How do I do this?


I suspect my first flubbed attempt at partition repair with ntfsfix may have been what caused the issue.

Any insight or advice from the techies here?

Copy out the files, delete the partition on the drive, create a new one, format it, and see if it works properly after that. You are saying that the drive capacity is showing up as 250,000,000,000,000 or something like that? With 4 sets of 000?

I was hoping there was a more non-destructive way of resolving the problem. And the clarify.. The partition is the correct partition size but what's happening is that it's literally showing the harddrives capacity as the maximum size the LRG addressing mode will handle. As in the theoretical upper addressing limit. This is only visible to the bios and certain HDD tools. Otherwise the drive is functioning normally.

I think something in the HDD's base settings got scrambled during the the fiurst failed ntfsfix attempt... I figured since a software glitch managed to cause the error that there must be a non-destructive software solution for it.


Or is this wishful thinking my part. Granted the whole series of events with that drive reads like a haunted computer story.

Just giving this a bump. I knew this was a rare problem but yikes I didn't think it was this unheard of. Also reformatting may cause more problems. Again the partition is the proper size but the total capacity available on the HDD is waaaay higher than it should be. More or less the theoretical maximum the bios can handle.

Well seeing how nothing new has been added I guess I'm stuck. My decision is at the moment to leave well enough alone..


I'm hesitant about formatting because if the Bios is reading the HDD capacity wrong it might create a problem with the creation of partitions. Anyone else have any idea how to fix this or any experience feel free to post.

Incorrect entries in the partition table. Scrambled file system leading to complete data loss.

If you don't value the contents of the HDD then just keep using it that way.

Okay.. checking my bios there are only two options Large and Auto. FOr both drives. It should be noted that the D drive is the same size, brand and model as the C drive though that gets detected as LBA. I think my suspicion that my botched ntfsfix may have screwed something up. After my next back up I'm going to try to run it again to refix whatever was broken.
