So I was trying to properly install a new 200G WD HDD on a Highpoint
controller and wasn't having any luck, so I figured I might as well try
getting the USB2 Enclosure working with the machine too while I was at it
(also a 200G drive, but formatted for NTFS), connecting the drive and going
back to seeing where I might have the highpoint controller recognized I
forgot all about the USB drive --- bad mistake.
I went into the /stand/sysinstall under fdisk and saw I had a 200G drive
there, Oh, I must have done something to enable the HighPoint controller I
said .. let's edit it .. Strange, it's reporting NTFS/QNX/.. did I get a
drive with something on it ? I was unable to mount the drive with NTFS (it
wasn't in my kernel) so I just said forget it and tried to fdisk, it tossed
a warning about doing the fdisk separately from the disklabel, so I said, ok
, I'll wait.. and went off to do the disklabel at the same time. at which
point on trying to disklabel the disc I believe the disklabel wrote out
(improperly) and then crashed the PC -- at which point I realized my
mistake. I don't think that the full write even started because it was a
hard crash and occurred very soon after I executed the command, I don't have
the debug screen that appeared afterward, it was a kernel panic.
This is the USB2 device::

Initially I attempted to just read the disklabel, but it threw a bad pack
magic number. So I tried to edit it with disklabel -e , I changed
nothing, but it seems the disklabel was written when I left the editor
regardless
Disklabel commands:
[Crappy]:log% disklabel -r /dev/da0

I know it's a 7200 RPM drive, with an 8MB cache and 200G of physical space
( ~ 186GB after formatting in NTFS), the Western Digital Special Edition
200G drive.
I want to restore my data, but I am scared to change the disklabel at the
thought of losing the 150+G of data that is on the drive. Can anyone PLEASE
provide details on how I might be able to restore my data, right now I can't
mount it anywhere? Any help is appreciated.
Thank you,
