Hi guys,
I have a 320 GB Western Digital hard drive model WD3200JB and right now its all messed up. It used to have 3 even partitions of 100GB the first blank and formatted, the second loaded with media and the third comprised mainly of zip files archiving documents I wanted off of the system disk. This was a second Hard drive so there is no OS partition, although I was planning on using the blank one for XP Pro.

I started to install the new OS, but when it asked me to choose a partition and there was only one in the list I put on the brakes and slaved the disk to another PC. Somehow the MBR was rearranged and there is now one unformatted partition of 128 GB and the rest is unused.

I think what happened involves the lack of support for drives over 137GB (128GB in windows) making my drive all messed up. I first thought of this when I installed the WD diagnostic tools on this PC and found that the MBR is FAT16. This should be NTFS, I think, or at the least FAT32.

Is there a way to adjust the MBR to be the way it was and attempt to get the partitions back? I can't chkdsk since the disk is unformatted and RAW and that would only fix the partition anyway. Anyone know a good utility for something like this? The WD utility is pretty useless for this disaster situation. I also don't want to jump in and risk any chance of recovery by repartioning, unless it is the only option.

1) Put in the XP installation disk and boot from it.
2) At the first screen that comes up select "R" to repair from the Recovery Console
3) Once the Recovery Console is open, type these commands:

bootcft /rebuild

then type "exit" to exit the Recovery Console. Reboot to see if this has worked.
