[comp.sys.ibm.pc.hardware] Hole puncher to transform DD disks into HD

conner@carina.unm.edu (Steven Conner) (07/21/90)

In Computer Shopper magazine I saw an advertisment for a tool that would
punch a hole in the corner of your 3.5" DD disks.  The ad claimed that this
would allow you to safely format and use it as a HD disk.

Has anyone had any experience with this or a similar tool?

Does anyone have an opinion as to whether this will work in a safe and 
dependable way?

I've had success just simply drilling a hole where the other square hole 
should be.  People will flame me 'till I'm brown and crisp on this one but 
it works!.  You simply have to be careful not to get any chips of the case 
on the floppy.  I've had no reliability problems this way.

Just food for thought.

I have used the tool advertised in Computer Shopper for quite some time.  I buy either BONUS
or SONY DD disk and punch them.  I have never had trouble with a single disk, though every
time I copy information to them, I do a COMPARE. The only trouble I have had was with some
mail order disks, but the compares failed, so I did not use them.

However, currently I am trying to install a switch on the drive so I can TELL it that the
disk is either HD, LD, or let it auto-detect.  That way I don't have to punch the disks.

By the way,  if you decide to get the puncher out of Computer Shopper, get the all metal one.
It is about $40 vs. $20 for the plastic one.  The metal one is much easier to handle.  Some
disk take quite an effort to punch through.  Others are flimsy plastic and may crack (like
the mail order disks that wouldn't work).

Ok.  That's nice, but it takes too long for me.  I just whip out a largish
pair of scissors and clip the corner off the disk.  This is best done with
a label already stuck on, as it will hold the two halves of the case together
during and after the operation.  So far, it works great.  You just have to
be careful not to take off too much... :-)  Also, you don't have to worry
about getting scraps from the drilling inside.

One last note:  Use caution when inserting so-modified disks into Macs.
I have seen a couple get jammed on ejects because the case has caught on
something and separated.  No problems on PC's, though...  Happing clipping!
