Yes, the MBR does not appear to be correct. Hs fixboot been run by any chance (from recovery console)?
No. The disk was originally on an XP system with the large partition patch to the registry. I accidentally connected to a system that didn't have the patch & the OS asked if I wanted to make a new partition on it .. :-/ oops. But I didn't have XP clean the disk.
About the read errors / UDMA: These appear to be real read errors and not the bogus ones we see in relation with the UDMA driver. So, we need to establish the disk health. I suggest you first create a disk health report (in DiskPatch startup menu select Options > create disk health report ... In the root of the DiskPatch diskette there should be a file called REPORT.TXT now. NOTE: You may need to delete that earlier logfile to make some room.
Sounds good. I'll do that.
If I'd had to advise without the disk helath report: There appears to be a serious problem with the hard disk and I advise to clone it ASAP.
Then, after we have cloned it we can try and see if we can repaair the partition tables.
Thanks for the advice. I just ordered another disk so I can create a clone. It'll take about 3 days to come, so I'll check the disk health, create a clone, and get back to you. Thanks for the suggestions!
