I get the Side 0 & Side 1 .RAW Preservation Stream files, but I don't get the MM001.IMG File that has anything other than 0 Bytes.

Likewise I can't use the Stream files to create a MFM File named MM001.IMG with this command:

Code: Select all

dtc -fMM001/ -i0 -fMM001.img -i4 -s0 -e39 -m1
I've used the exact same commands to create a .IMG file of a "TRSJ" Floppy with the following 22DISK Definition:
BEGIN TRSJ TRS-80 Model 4,4P Montezuma Data 200K - SSDD 48 tpi 5.25"
DENSITY MFM, LOW
CYLINDERS 40 SIDES 1 SECTORS 10,512
SIDE1 0 1,3,5,7,9,2,4,6,8,10
BSH 4 BLM 15 EXM 1 DSM 99 DRM 127 AL0 0C0H AL1 0 OFS 0
END
and it works fine, while the 170K floppy image file (IMG) can't be created.

What is preventing me from creating a valid MM001.img file? I've created three different floppys on the Model 4, and I get the
exact same results, when I create the IMG file.

Thanks.

Re: [SOLVED] MFM Copy of CP/M SS/DD Floppy on 48TPI Drive

Post by ldkraemer » Sun Jul 27, 2014 5:37 pm

I finally figured out that the default Sector Size is 512, and this CP/M Boot Floppy has 256 as Sector size, with 18 Sectors per Track.
So, I inserted the correct Parameters as arguments for the Command Line Usage, and the MM001.img file was created:

Code: Select all

dtc -d0 -fMM001/ -i0 -z1 -n+18 -fMM001.img -i4 -s0 -e39
Thanks.
