Have to say it's a tad tough going, but quite a bit of fun at the same time. ;) Gerard, yes, this would be a good opportunity to wipe it and start again. If only it wasn't for those MP3s. ;) For those who couldn't read my last email because it was rather a bit too long, the short of it is that FDISK fried my USB HDD's MBR when I asked it to change a partition type's from NTFS to FreeBSD. Why did this happen? Does anyone have a large (blank!) USB HDD that they could experiment with? It would be great to see if this problem is replicable on FreeBSD. If so, I would suggest that a PR needs to be raised against FDISK. For anyone in the distant future who perhaps has trouble with their MBR and/or partitions I've found a stack of great literature on the web I'd be more than happy to post up. Also, tools that you might be interested in in order to "investigate" things are: - dskprobe.exe (WinNT / XP "Support Tool" for hex viewing disk) - dd (Data [File] dumping tool in Linux / BSD) - hd (Pretty print tool -- used with dd it apparently gets similar results to Dskprobe.exe) - gpart (Partition search and retrieval tool -- not yet tried myself) - part.exe (Ranish Partition Manager tool -- runs under DOS) They would be the main ones thus far. Anyone know of anything else I should be checking out? As it is, now that I am armed to the teeth, I hope to find out how much damage my USB HDD suffered, and then hopefully patch up the MBR and/or Logical Drives I lost. Keep you all posted. Cheers, Jarrod.
