It did boot off HD but running WinUAE in XP allowed me to do a backup of the HD but now the Walker refuses to see it anymore.

Take a look at this:

IMPORTANT NOTE
==============
If you boot Windows 95 (don't know about 3.x, 98 and NT) while you have an Amiga harddisk connected to your PC, it will overwrite the bytes 0x00dc..0x00df of block 0 with garbage, thus invalidating the Rigid Disk Block. Sheer luck has it that this is an unused area of the RDB, so only the checksum doesn's match anymore. Linux will ignore this garbage and recognize the RDB anyway, but before you connect that drive to your Amiga again, you must restore or repair your RDB. So please do make a backup copy of it before booting Windows!

If the damage is already done, the following should fix the RDB (where is the device name).

DO AT YOUR OWN RISK:
^^^^^^^^^^^^^^^^^^^^
dd if=/dev/ of=rdb.tmp count=1
cp rdb.tmp rdb.fixed
dd if=/dev/zero of=rdb.fixed bs=1 seek=220 count=4
dd if=rdb.fixed of=/dev/
