[comp.sys.atari.st] 1.44M external floppy on ST?

brian@.Waterloo.NCR.COM (Brian W. Gamble) (02/13/91)

I think my last post must have landed in the bit-bucket... Oh
well...  If all else fails, try again...

I've got an Atari ST (one of the old Nov.20/85 1040's) and just
bought a 1.44M floppy drive to attach as drive B:...

QUESTION ONE
Do you need to do anything special to get 1.44M out of it?  I can't
seem to get it to read a HD disk...  I've found a SW/PD formatter
called Diamond Format, which formats to 1.44M (or 1.6M if you use
more sectors than usual).  It also seems to be a stand-alone portion
of a hard drive backup program.  Do I need to find a special driver
or something?  The drive works fine as a double density...

QUESTION TWO
Does anyone know where I could find a 14 pin DIN (ie, the ST's external
floppy drive port) plug adapter, that has a female 34-pin (ie, the
floppy drive's bus) port on the other end?  Or am I doomed to building
one?  Given the half-dozen or so 3rd party manufacturers of external
drives for the ST, a part like this HAS to exist, right?

There is a product called the PowerDrive.  It comes in two parts: a 
drive controller replacement and a 1.4meg drive.  You can buy the 
drive separately, but you must by the special controller from them.  
I think it uses the faster WD1772 (is that the right part #?) 
controller chip.  The board itself costs $139.95.  I think they 
recommend a Teac drive.

A friend of mine has this installed on his 4meg STe.  He says, not 
only is the 1.44meg drive faster, but his external 720K Indus drive 
jams.  He says you can see on the track reading that it's much 
faster.  However, he adds that there is some incompatibility with 
copy-protected games.
