This information is really not sufficient to say anything. The number of sectors per track does not define the format, or the framing. So, is this for example PC type of disk format?


Thanks for the reply. Its for some old CPM computer. RAW image is 800Kb exactly.
On linux PC, I can read tracks with:
fdrawcmd read 0  0 0 17 3  0 0x1b 0xff length=5120 rate=2 need_seek track=0
Better sorry than worry.

thanks.
I would like to make a .raw image (with tsgui, dcp, dic or similar) as a backup and later write copies. I had managed to make one with MFMWarp, but its too large.
I've tried fd.device from xfs, but it seems to always use 512byte sector size.
will try mfm.device
Better sorry than worry.
