I don't think my first message made it through so I'll try again.
I was wondering if there was any reason why I couldn't format a Prodos disk
at 1:1 interleave.
I've heard all the things about GSOS not being able to handle 1:1 all of the
time but with a Transwarp GS and diversi cache, I think I could. Why? well,
I was using MacTrans GS to transfer some files (background: I heard that
HFS disks are formatted at 1:1 interleave) and MacTrans read them so fast I
was really amazed. It read a 120K file in about 5 seconds (much faster than
GS/OS could). I decided that it must be the 1:1 interleave.
anyway, is there a program to format 1:1? Is it possible (I mean like
can Prodos structure handle 1:1? I'm pretty sure it can).
thanks for any help....

One thing you didn't mention: are you using an Apple 3.5 Drive, or a UniDisk 3.5" drive? The UniDisk can only handle the slower 4:1 interleave. I can read in a 150K file in under 5 seconds with my floppy (no TransWarp, no ZipGS, nothing). The data transfer times for the Mac and the GS are identical (32K/sec maximum), so the interleaving isn't affecting anything. I've never heard of a floppy disk formatted at 1:1. Heck, if Photonix won't let you do it, then you probably CAN'T do it... :) \/\/\/\/\/\/\/\/\/ | Brian T.

How many sectors are on one track anyways? ZZ Copy 1.0 let you set the interleave anywhere from 1:1 to 9:1, but they probably took the weirder ones out since there isn't really a practical use for them (who wants to make disk access slower?) -- David Huang | Internet: ifar355@ccwf.cc.utexas.edu | "My ganglion is stuck in UUCP: ...!ut-emx!ccwf.cc.utexas.edu!ifar355 | a piece of chewing gum!"

I forget the name off hand, but I have it somewhere. Hmmm, now that I have a ZipGSX, I might just try formatting them 1:1 interleave. whitewolf@gnh-starport

I think there are about 3 or 4 different 'sections' on the disk. Each section has a different amount of blocks. I forgot which book that's in.

Here's how it works: Tracks #sectors/track 0-15 12 12*16=192 16-31 11 11*16=176 32-47 10 10*16=160 48-63 9 9*16 =144 64-79 8 8*16 =128 ---------------------------------- Total => 1600 The disk speed varies at five different speeds depending what track you are on. -- ------------- Jerry Penner ...!alberta!bode!jpenne
