AEHD Applied Engineering High Density Floppy for the Amiga.
Has anyone got the AEHD Applied Engineering High Density Floppy it to work in high density mode with OS 2.0 or above?
The AE 1.52 meg format mode would be great, the commodore 1.76 meg format would be better.

I have one. Never could get it to work on anything but 1.3...sad too, its a really snazzy drive. I'd love to know if its possible though - I have a whole load of HD disks to go through from my A4k that I never backed up before selling its dead carcass with the HD drive. :-(

I have never seen or heard of this drive. I gather it must use a software patch to work? The 1.52Mb size is wierd. Has anyone checked out the software, to see it can be upgraded?

Applied Engineering primarily made Apple and Mac hardware.
The AEHD was probably there only attempt to get into Amiga Hardware.
The AEHD was a Mac HD floppy drive modified to work with amigas.
At the time OS 1.3 was out and commodore did not have a HD floppy standard, so AE made there own formatting standard which resulted a 1.52 meg disk, I don't remember how many tracks and sectors AE used.
After this drive came out the a3000 came out (and OS 2.0). The AEHD driver were incompatible and with commodore coming out with a HD floppy standard, I believe version 2.05 of the kickstart, rendered this drive obsolete.
This drive still works as a low density drive with out drivers, but it would be cool to get it to work with a modern OS, either with its 1.52 meg format or with commodore's 1.76. The latter maybe physically impossible as mac drive HD spin speeds are very different to commodore HD floppy spin speeds.
It is a very nice drive with electronic disk eject. The drive was very quiet, unlike most amiga floppy drives.
