My big box of serious software arrived via Fedex today. It looks like I am going to have nightmares imaging some of this - 5.25in DD and HD floppies, 3.5in 1.25 and 1.44MB ones. I will be asking for advice shortly. Of course, some of them I haven't a clue what they even are! :oops:

So i started with a small pack and thankfully my USB floppy successfully read the two disks. But, would someone please tell me what this is? :oops:

I figure I am out of my depth here, and any advice and assistance would be most welcome.

I am having a fair amount of success imaging 3.5in floppies. The BIG problem is the 5.25in ones, most of which I cannot read. I am using a few old PCs because I know that modern ones often have issues driving 5.25in drives from my experiences imaging my own PC ( not PC-98 ) disks. I have 5 or 6 drives of various makes which I have checked read properly on a couple of "reference" PC 1.2MB floppies. I have managed to image 2 or 3 floppies using these drives and Disk Image, but the rest just give immediate errors - sector not found etc. I am fairly sure they are HD disks - from the labels and the packaging, and they do not read in a known-good 360k drive.

So what is going on ( I cannot believe the 6-8 disks I have tried are bad )?:

1. The disks are actually bad
2. I am stupid ( known to be true )
3. There is a non MS-DOS format I do not understand
4. I should be using some other program
5. They can only be read on a real PC-98

:?:

Then there is an 8-inch floppy with Supercalc on it - but we won't worry about that one LOL. :wink:

Update. I am having a lot of success with Omniflop. I'll post once I have done more.

EDIT.

The problem format seems to have been the 5.25 inch 1024 bytes per sector, 8 sectors per track, 77 tracks per side, 2 sides format which is not a PC 5.25 inch format.

Omniflop is quite amazing! It produces files which, if given a .hdm extension, are readable in Neko. I hope I haven't spoken too soon, but at least my faith is restored in my old drives, especially the TEAC one I am using at the moment. Clunk clunk clunk clunk x77 , and the disk is read. And the actual floppies have survived the trip half way around the world. :D

EDIT.

There are some weird formats out there!! :wink:
