![]() ![]() ![]() For that reason, PC drives can usually create Mac HD disks, but they cannot create Mac DD disks. So whereas there are hardware requirements for supporting the creation of Mac DD disks (the drive needs to be able to vary its speed on demand), writing Mac high density (HD) disks is usually just a question of format. In contrast, the Mac's support for HD disks employes a constant velocity (as does the PC), and therefore, PCs can write Mac 1.44MB HD disks, but they usually cannot write Mac DD disks. With this technique, the drive ran more slowly when the read/write head was at the outer edge of the media, allowing more data to be stored there. For double sided, double density (DD) disks, the Mac used "Group Code Recording" (GCR) to vary the speed of the drive, and thus increase the amount of data that could be stored. I suspect that what's causing you confusion is the difference between Mac DD and HD disks. As I recall, the Spectre GCR will read HFS disks just fine. I'm confused as to why you are worried about MFS vs. It seems that StuffIt for Windows strips the Resource files so anything I try to move from Windoze will not work. I have a Discovery Cartridge so if I can get a Mac 800k I can convert it to the Spectre format, but Im knida stuck right now. I only have an 800k drive so I cant do the 1.44 floppies. There are some PC utilities that can do this, however it seems most are geared towards HFS and not MFS sizes. Apparantly you can in theory write this out to a Macintosh formatted disk. Though doing this just for fun, I really want to figure this process out. ![]()
