I’ve been getting into some weird computers and devices recently and have had to forge my own path on reading and writing …

What happens if you try to study a Famicom Disk System floppy this way?
I remember my Acorn BBC model B duel 40/80 track disc drive cost more than the BBC model B Computer, i remember being a child at the time feeling shock at this and thinking I could also buy a Commodore 64 computer for the price of the disc drive
but upon using the disc drive i very soon understood how awesome a disc drive was compared to using a tape cassette and playing Elite on disc sold me to the BBC B and disc drives
I see that copy of Nox in the back. Still one of my favorite games!
Hey can you do a video on RLL/MFM ST506 hard disk and formatting? Is Interleave really needed on SSD replacement systems… just curious about any caveats you might know about.
Fascinating, but… I don't have a PC.
I'm looking forward to requiring my Atari Home Computer Systems that were taken after I moved to California thirty years ago. The photo I saw showed at least one 1050 floppy drive and a couple of cases full of floppies.
Originally, Atari DOS 2.0S formatted 5 1/4" floppies in single density. Then Atari DOS 3 came out and offered an "enhanced" density format. I don't remember now if it provided more sectors per disk or just stored more data per sector, but the result was about a 50% increase in data storage per disk.
I added a bootleg of a third-party ROM to my floppy drive to provide true double density.
If these old computers actually still work, I plan to see if I can read these disks and copy the files to an SD card using modern accessories for my old computers. I think I had some disk editor software back in the day and I have a detailed source listing of at least the original DOS 2.0S software.
i have a load of 720 which have been changed to 1.72 disks. also used pcbackp and cpbackup for backups. so kinda stuck with them. wouldn't winimage also work?
I only got to "forget everything" in this video and now the police are telling me these are my children.
Another neat tool for working with flux images is SAMdisk by Simon Owen. It works entirely at the command line, so it can be worked into a batch process. It works best if you combine it with the tools that are part of LibDsk.
What a fantastic video. This will be so useful for generations to come. Make sure you backup the flux map of this video!
I didn't understand a single word, and yet I loved every second. Shelby rules!
I just have one question: Where do I get raw dumps of Kings Quest (PCjr)? I have bought anthologies and GoG collections, but none of them go that far back. Apparently the copy protection was a bear, and before flux imaging, there wasn’t a good way to get a perfect 1:1 copy that didn’t require a crack.
Sir, there is a bee on your hat.
TLDR please. I want to preserve my floppies. What do I use?
Wow! This is super timely with my own backup project underway. I cannot believe the massive depth this actually goes into.
great video. although I must admit, I spent half of it trying to figure out how you'd get a 5.25" disk with different formats on each side. My guess: they formatted it first in a system like a PC with a double-sided drive, then needed to reuse it on a single-sider like a C64/Apple II, and only bothered reformatting the side they used for that?
This video was awesome. Helped me a ton to better understand disk formatting. In the process of trying to write downloaded images to physical floppies for multiple vintage machines, but mostly for Kaypro and TRS-80; Apple is easily taken care of with ADT Pro. Thanks for the education! 😃
wonder if any hidden easter eggs in those old weird old floppy formats
Also may wish to cover Write-PreComp at track 43 on some 8" Floppy Drives. Ref the Centurion minicomputer from the 1970-1980's.
Love these explainer videos. I don't own any retro computers but I enjoy watching them.
Wha?????
Thanks for presenting. I remember Copy to PC and tools of such and made a BIN file of a Floppy and image of Zork (way back when). I still have some of the old floppies around.
Should do an episode like this on zip disks at some point, I have a few that decided to stop working because I think the tracking sectors have gone bad. And of course they're the ones with data on them that's not backed up which I was trying to do when I found out.
Weird somethings weird with the audio. Curious what caused it. It's like the game is turned all the way up and the mic is low or may be a bad cable? I'm hearing a static he knows over voice. Curious from an Audio perspective I'm assuming you figured out what it was.
Disk formats are something that I watch from afar these days. Just not enough time for my regular systems job to work with them myself. Retirement is only few years away. Maybe I will come back to it.

Another weird case is the PC98. In many cases, they just ran the motors of the drives at 360 rpm instead of 300 rpm. Otherwise, they had normal MFM encoded.
Wow great explanation! will have to watch again for it to sink in, lol. Does clear up alot for me though.
Great video dude, well done !
Notification Squad! 🙂
