OK, I know there are many similar threads here, but I've searched through them and haven't found exactly the same issue.
History: Dell Laptop w/XP SP3. ~70GB drive was failing. Bought a new ~550GB drive and cloned the old to the new with Clonezilla. Used gparted to extend the partition to fill the new drive. Reinstalled XP because the drive wouldn't boot. (Guessing the MBR was hosed by gparted?)
Problem: Windows runs, but won't recognize the full drive. My Computer still says 74.5GB Capacity. But Disk Management disagrees with itself. On the lower pane where it shows the Disks graphically, it says (correctly) "C: 596.17 GB NTFS Healthy (System)." There is no unallocated space. (Before I used Gparted, this area showed the 74.5GB partition and the other ~500GB unallocated.) But in the upper pane where it shows the list of Volume in tabular form, it says "Capacity 74.53GB"
So it looks like the partition resizing took, but windows doesn't want to use the whole partition?
(I checked quotas, they are off. I assume the BIOS is set up ok, because gparted saw the whole drive, as does the lower pane of Disk Management. It's SP3, so it should handle big drives, and it's not even stopping at the 130GB Big Drive limit, it's stopping at the old drive's capacity.)
Well, that certainly sounds like if could be the issue, but none of the fixes in that link (or other discussions I've found on the Dell truncation issue) seem to work.
I have done the following:
- MHDD wouldn't see my drive for some reason
- HDAT2 shows no HPA in the SET MAX (HPA) menu
- I tried adding a 1 sector HPA and then removing it, but that didn't do anything.
- I used Roadkill sectedit to look at sector 3 of the physical drive. It didn't look like this one: http://i16.photobucket.com/albums/b16/bjkdegree/lba-3_d...
(which this guy here: http://newsgroups.derkeiler.com/Archive/Alt/alt.sys.pc-...
says is a typical dell sector 3 that needs to be zeroed out)
In partitcular, it didn't have the XLDR text.
- but I tried zeroing it out anyway (after backing it up).
- HDAT2 still showed no HPA
- windows still won't see the whole drive.
FYI, the drive is a Samsung drive. Would the Hitachi or Seagate tools work?
Also, I don't even have this "MediaDirect" button on my computer. Is there something else that lurks in LBA3? Are there more sectors I need to zero out?
Anyway, I'm stumped again. Your link seemed to fit my issue at first, but not when I delved into it deeper. Any more ideas?
At this point, I'm starting to get really frustrated, and I wish I'd never tried to clone the old drive, and just started fresh. Is it too late for that at this point? Is there a way to totally wipe this drive back to its original state (including all wacky hidden stuff like HPA, the MBR, the partition table, and anything else I don't know about?)
Using EaseUS partition master, I resized the partition back down to the minimum that would hold the data on the disk, then resized it back up to the maximum and the problem is solved! My Computer shows the full 596GiB!
