I've done a lot of reading the last couple of days into the MBR and the
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
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.
