The problem appears to be with XP, not with the Matsushita-made LS-
120 IDE drives.  (They also were produced for SCSI).  Mine worked 
just fine in Win2K, but XP hangs (with no hardware changes) during 
the boot process.  The problem appears to be related to the chipset 
and drivers of the host; some have reported success in getting the 
LS120 to work on XP, but by no means is this common.

And no one's going to take the time to find out what's wrong with 
what's considered to be an obsolete device.

One nice aspect of the LS120 is that it would also read (but not 
format) 1.23MB "DOS-V" Japanese-format floppies.  Most USB 3.5" 
drives can also do this.
