I recently brought a Toshiba 3.5" 1.44 meg High Denisty
drive in hope of being able to do a "trick" that is done
on Toshiba laptops and IBM PS/2 computers...

I wanted to do some high volume backups by using regular,
low cost 720K generic disks and formatting them to 1.44 megs..
I heard that Toshiba drives are capable of doing this...
I also have a Western Digital WD1006-RA2 controller which
supports such "intelligent" drives.. I am also using Pheonix
AT BIOS 3.10

However, I have not been able to format the disks at 1.44 megs..
It keeps on giving me invalid media/bad track 0... The funny
thing is, is that I can use a legit 1.44 meg diskette, cover
the high density hole and format the it at 1.44 megs even
though technically the drive thinks it's a 720K disk... But
this is ONLY if I use a REAL high density disk and not a fake
720K disk...

My question is how can I get it to work.. Is it something
with DOS or the BIOS..... I know Toshiba laptops  and PS/2
can do this but I can't get mine to work.. (I am running
PCDOS 3.2 by the way....)

Any ideas? Please email as I don't keep up with the newsgroups...

Thanks in advance,
George
