I have been trying to use PowerQuest's Partion Magic 7 but it prompts
an error saying my partition table is bad(see text below). Should I be
concerned? Can one repair a "bad" partition table? If so, How?
Thanks group!

Tap <F8> on startup to enter safe mode. Run scan disk and choose

"scandisk" repairs damaged partition tables?

since when?

I always thought "fdisk /mbr" fixed damaged partition tables by loading a
"good" copy in place of the damaged one.

Was I wrong?

/MBR will not touch the partition table at all. It will re-write the
*pointer* to the partition table only. Be careful when using this,
however - there is at least one software contraindication. Also -
"EZ-Drive" installs to the boot sector, but I don't know where exactly, so I
don't know if re-writing the MBR will affect it.

As for SCANDISK, I understand it can *find* partition table errors, but find
no evidence it can actually repair them. There are, however, third party
programs for that.

There's a REALLY good and effective way to do this using the debug command
in DOS, unfortunately it's just something a friend of mine showed me and I
wrote down in my office (not where I'm at now), so I'd suggest reading up on
DOS commands--anyone know where some good DOS literature is?

DO you want to restore an existing partition table? Or repair one that has a
problem and will not allow you to fdisk the drive. This script will allow
you to clear the partition sector. After that you can repair the MBR if you
want. Utilities can do this too. I like debug so here is the way to do it
A:\>DEBUG
- f 200 L200 0
- a 100
xxxx:0100 mov ax,301 (ignore segment:offset values at left)
xxxx:0103 mov bx,200
xxxx:0106 mov cx,1
xxxx:0109 mov dx,0080
xxxx:010C int 13
xxxx:010E int 3
xxxx:010F (Press ENTER an extra time here)
- d 100 LF
xxxx:0100 B8 01 03 BB 00 02 B9 01-00 BA 80 00 CD 13 CC
(make sure that hex values match above line before proceeding)
(if values do not match, type Q and start over)
- g=100
(ignore register display)
- q (quits back to DOS)

Yeah for old school stuff.....!!!!!
DO this from a bootable floppy with fdisk and debug. Your all set.
