I think you might be confused. There are no 360K 3 1/2 inch disks. On IBM systems you have two size diskettes 5 1/4 and 3 1/2 The 5 1/4 has two densities: 360K and 1.2meg. The 3 1/2 has two densities: 720K and 1.4meg. Call up a BBS and download the demo version of CrossDOS or go to your dealer and buy it for $30. It reads 720K 3 1/2" disks. The demo is read only. The commercial version is read and write MSDOS. No program on the Amiga can read the 1.4Meg diskettes because of a hardware limitation in the Amiga disk controller chip.

The 3.5 inch drives will be more than happy to format to 360K, even double sided. Also, the old IBM single sided 3.5 inch drives were 360K. - R'ykandar. -- | R'ykandar Korra'ti | Editor, LOW ORBIT | PLink: Skywise | CIS 72406,370 | | Elfinkind, Unite! | phoenix@ms.uky.edu | phoenix%ms.uky.edu@ukcc.bitnet | | "Careful, mom, the toys are loose!" - from The Wizard of Speed and Time |

Also, the old IBM single sided 3.5 inch drives were 360K. On a side note, it is simple to install a 3 1/2 drive in and XT, the only problem you have is that most XT floppy controllers do not know how to format a 720K drive so they format it to 360K. Hence I have found that I can read and write 720K floppies on an XT, but must first format them on an AT so that they are 720K. (I use an XT at work to download amiga source/binaries from this net and then use crossdos to put them on my A1000). For all you that are thinking - use the right flags and you can format them to 720K - save your breath, the controller/bios I have does not understand the flags. Monty Saine
