Don't do it. The magnetic quality of the 1.4K disk are different that
the 800K disks. The FDHD drive ueses a stronger current to write to 1.4
K disks. Data may be whiped out if you use 800K disks as 1.4K

Ok, here's what I have heard about hole punches. You can get them through mail order, there are ads up and down the Computer Shopper magazine (looks like a big telephone book, costs $2.95). But... here's what I heard about the practice: Don't. The companies that produce the punchers say there is no physical difference between a DS/DD and a DS/HD. WRONG!!!!! If the disk is any good (Maxell, Fuji, etc.) then, on HD disks, they put an extra coating or two of magnetic retention glue that keeps the data from being disrupted by outside magnetic fields (like CRTs, static electricity on the drive head itself, etc.). When you store twice as much data as was orignially determined to be possible, they are twice as prone to data loss. As for the disks these hole punch companies are talking about, the companies that put DS/DD tested disks into DS/HD sleaves, I would like to see a list (mind you, a visited-the-factory-and-caught-them-red-handed list) because some hefty law suits could be put into motion PDQ. F'r Instance, how many of you have bought a fresh box of DS/HDs and found one bad fresh from the box? Two? Three? $5.00/disk (retail). I swear by my life I will never archive anything on a DS/HD disk (I have enough problems with DS/DDs...). So all I say is Caveat Emptor with these hole punchers- realize the first hole puncher ever to come out had problems because _microscopic_ particles of plastic got on to the disk, scratching and destroying it. Thank you for your patience. (.X.) ( -__- jbaron@silver.ucs.indiana.edu
