No, it just corrupted EZ-BIOS (found on WDC drives, but MAXTOR has 
something similar)

There are at least three ways to remove it:

1) Use the WDC EZ-DRIVE floppy disk (I don't have it) to uninstall.

2) Use linux dd to put a copy of the correct partition table where it 
belongs.  This looked complicated and time consuming but it retains your 
data.

The partition table is at byte 466 (446?) of the second 512 bytes and 
should be copied to the same location on the first 512 bytes.  The linux 
method saved it and then wrote it, I think.  It used dd and nc.


3) Boot from DOS floppy disk.  fdisk, delete any partitions, make one new 
DOS partition (any size) and format it.  fdisk /mbr

No more EZ-BIOS.  ("This sends EZ-DRIVE to hell, or heaven".)

This apparently puts a copy of the real partition table from the second 
512K to the first 512K, where other things can find it properly.  PQMagic 
is happy now.  We have been trying for years to get rid of EZ-DRIVE and 
gave up and used the disks for one large partition instead.

Is there a simpler linux equivalent of fdisk /mbr?

The no-power-on problem was solved by pushing the front cover back on all 
the way so the switch made contact.
