You can now modify the desired numbers of reads you want your data to have and cycle through all flux rotations:

ohh this one has the stoned virus!

#softwareArchiving #retroComputing #retroVirus

a hex editor view of an image, it has the "Stoned" bootsector virus. There is a text that says 'Your PC is now Stoned! LEGALISE MARIJUANA!"

I received a big box with floppies and I already spotted lost media. Ohh shiinies! #floppy #retroComputing #softwareArchiving #RecoveryWhiskers

Was there ever a concept of emulation for embedded games? E.g. #Tamagotchi being one of the most well known? But there were old super mario handhelds and watches too...

I filed some things to archive

PC LOGO (KRS): https://archive.org/details/pc_logo_krs [lost media, found this on a floppy]

Floppydriver: https://archive.org/details/flpydrvr (archived in some deep archive but wasn't filed as an item with metadata)

when you get an original disk that looks like it's nice to have a flux copy of, but you find out it was modified by Windows Volume Tracker.

today I managed to hack in more parsing and a warning message for atari ST floppies that go to track 80 or 81 (maybe also 82?).

My teac drive that I normally like doesn't go past 79. Another random drive from my pile does.

Added a warning about this to the status window.

I did some refactoring so the software now reads past those tracks if it detects an Atari ST image. One of the problems I need to fix is that the first floppy I tried has data up to track 80, it claims to have 10 sectors per track but all sectors at track 0-79 have are 9 sectors, but track 80 has 10 sectors (all empty).
That bugs out my software right now as it doesn't have support for tracks with different sector sizes yet.

#RecoveryWhiskers #floppy #retroComputing #softwareArchiving

Screenshot of my computer running recoverywhiskers. There is a warning that this disk may be larger than normal and you need a disk drive that can move the head to track 80

me: "I need to test #RecoveryWhiskers with a DMF floppy"
me: forgets for weeks
me: reads a random floppy and it turns out to be formatted with DMF settings and it works perfectly

Weekend progress on #RecoveryWhiskers :

Once the sectors containing the file allocation tables (FAT) is read, it will show you their size or if the FAT is empty.

next up will be adding a file listing and also make the program smarter so if it detects a large area of empty sectors and that area is empty at the file allocation table (if this is read correctly) then it should assume these are actually empty sectors.

I didn't get to it this weekend and I have work to do that pays for my my living (ugh)

screenshot of RecoveryWhiskers, reading a floppy, paused at reading side 1 track 9.

The information window shows that the file allocation table on the disk is empty. The sectors don't look empty, indicating that there is deleted data on the disk.

#RecoveryWhiskers now has some actual information of the floppy when available.

Some more to follow requiring more refactoring..

'Screenshot of a terminal window with RecoveryWhiskers. It loaded a file all but one sectors good. It has a flux view on the bottom and a new information windows with a quick overview of the keys and an information window has stats about the FAT Boot Parameter Block of the disk, including the label, size and FAT/root directory locations

Quick development update.

Information: Meow!

@grumpygamer is there a chance I can get hold of those floppies for archival?

(and behold if you try to read them yourself, this brand of floppies are prone to be moldy)

#softwareArchiving #RecoveryWhiskers

anyone in here by any chance has a Zenith DOS 1.x #floppy either as a physical medium or an image file?

There's one on the internet I found from Winworld (that is also the one I found on the Internet archive) and I suspect this is a bad read

A flux copy is preferred.

#softwareArchiving #retroComputing #zdos

In a couple of hours I managed to recover a huge part of data from an erased #floppy .

I made flux copy and loaded it to HxceFloppyEmulator, those are the first two images.

I managed to recover a lot of data with the software RecoveryWhiskers that I am writing.
I found some data that looks like a German MS-DOS 6 boot disk with Doublespace.
The file system data was properly blanked before it was erased (it's all blank data, I can verify from the flux view).

The way I recovered data is to slow down the the disk manually. I am baffled myself how well that worked.

screenshot of a floppy disk visualizers showing a disk with all unreadable sectors. The inner section seems to be empty data

flux view of a track. It looks like structures of sectors, but the timings are not readable anymore and it has a lot of timings that look like noise.

same sector in RecoveryWhiskers, I managed to recover this track it in 5 reads. The flux view shows a very wavy flux.

It also shows a bunch of sectors missing, some tracks have 1-3 sectors missing

a screenshot of the exported image file in a hex editor. It shows some German strings, talking about MSDOS version 6 and Doublespace

Folks going to #WHY2025, if you have #floppy disks lying around (especially those that might have data), please bring them to me on site - I am at FoodHackingBase!

I am working on RecoveryWhiskers, my new data recovery program for floppy disk and always want more old media to backup.

Edit: Bring me any kind of floppy - I only have 3.5 and 5 1/4 drives at the moment. Bring me more obscure formats and drives if you have one lying around

#WHY #retroComputing #softwareArchiving #software #archiving

screenshot of my program. it runs in a terminal, shows a representation of sectors found on both sides of a floppy disk. The bottom side read correctly, he top side (left) has both track 61 and 79 missing sector 6.
The cursor is on the top side, track 61. Below the grid layout there is a graph representing the flux view showing read 1 of 200. A massive vertical spike intersects both what looks like the 5th and 6th sector on the graph

I uploaded a German curiosity!

did someone hang this #floppy disk to a fridge? #softwareArchiving

A flux image of a floppy disk, 4 sectors are really bad with one entirely missing. The top side shows the same pattern mirrored.

#softwareArchiving

I am writing a new frontend software greaseweazle.

I wish someone paid me for doing this because I am having an #adhd problem of not doing the actual paid work until one more thing is done.

[I am going to link to this project in the future, it's not in a state I want to share it with people that might actually want to use it in the current state yet]
