Re: Bad Distribution Disks

IFW, yeah they're 5.25''. I don't think I see much of a size difference between the jackets, but I'll try swapping it and using IPA when my next one comes in. I've got a spare drive I don't care too much about sitting around here. What method did you use to clean them? I wouldn't recommend it to any...

Bad Distribution Disks

I'm having an issue with a particular expansion pack, The Secret Missions for Wing Commander, which I think is due to them being distributed on a cheap batch of floppies. I've gone through three copies of the game so far and each one scratched up real badly in my drive. I've attempted to release som...

Re: One-pass "flippy" disk support is here!

For some strange reason side 1 does not appear to contain any recognizable data when using PCE's conversion tools or when attempting to view track information using HxC's floppy emulator software, but DTC can create images just fine using the stream. And this is only an issue with one-pass flippy di...

Re: Apple II floppy question

Have a similar question. How do I know when to use i8 vs i8a? They appear to produce similar results

Re: Early IBM PC/PCjr flippy disk.

Okay, thank you. Luckily this was a recent eBay purchase and I'll be able to return it.

The unformatted tracks I was most worried about were actually track 0.0 and 0.1. Is this actually a thing outside of MFM?

This is my first flippy disk, but I've had earlier IBM releases that used MFM. Is this the result of loss of data or maybe an rpm issue? It does the same thing on unmodified drives so I wouldn't imagine it's an alignment issue.

Early IBM PC/PCjr flippy disk.

I'm getting results that I can't figure out. It's an Ultima III flippy for IBM PC/PCjr and I can't seem to get a proper dump of this disk. MFM Sector Image is showing up blank, but I'm getting results when I try to dump using FM Sector Image. I switched sector size to 128KB and it started showing up...

Re: One-pass "flippy" disk support is here!

Just wondering how everyone went about making the bypass circuit. I'm new to the whole custom pcb thing.

Re: Instant Bad Sector w/ no retry

An offtopic question, but are frankenstein streams acceptable for preservation? Streams with tracks taken from different drives and or different disks.

Re: Instant Bad Sector w/ no retry

If the format is unknown/unformatted there is no point in retrying since it will remain that way - except for some kind of damage/misalignment, as SomeGuy wrote above. I'm sorry, I should have been more specific. It was actually reporting it with a big B and not as No Format. But I figured out that...
