Hi,
I needed to rebuild my daughter's PC (B). I decided to reformat the drive from my machine. (Could not seem to get the Recovery Console to work on B). The story goes as follows:

Machines A & B both Win 2000.



1) Unplugged 250Gb HD from slave on UDMA 2, Machine A

2) Replaced with 60Gb HD (reconfigured as slave) from Machine B to be formatted

3) Attempted format from DOS prompt, gave a message like the one below

Unable to format, drive in use , could drop the connections and format may be possible (Y/N) (cannot remember the actual wording here)

4) Responded "Y" and Format was completed successfully

5) Used 60Gb drive (reconfigured as master) in other machine successfully (loaded Win2K etc etc)

6) Replaced 250Gb drive onto UDMA 2, Machine A and rebooted

7) Disk not present, shows up in disk management as Disk 2 (with red/white cross) - Dynamic Unreadable

8) Defragmenter recognises the disk with correct name and will defrag successfully





Seems to me that I have inadvertently screwed up my Win2K's view of the hard disks on the system. Don't think I can have done any damage to the 250Gb drive as it wasn't connected when I carried out the format.



Any suggestions or info on this will be much appreciated

For a disk that size you need at least SP3 and edit the registry, see
http://www.48bitlba.com for details. If those requirements aren't met,
Windows can not access the LDM located at the end of the disk.

7) Disk not present, shows up in disk management as Disk 2 (with
red/white cross) - Dynamic Unreadable
8) Defragmenter recognises the disk with correct name and will defrag
successfully

It's really dangerous to defrag if the above conditions aren't met.
