If you’re a big retro tech fan, you might still have a floppy drive on hand, or even some sort of high-end disk imaging solution. If you’re a little less committed, you may still have plenty of disk images on your hard drive for various reasons. Either way, you might find [0ldStaph]’s latest project to be useful for examining any disk images you have on hand.
FloppoScope is a browser-based tool for analyzing floppy disk images. Despite being browser-based, everything runs locally, so you’re not actually risking any sensitive data by using the tool—though we can’t imagine you’ve got too much Top Secret intel stored as floppy disk images, anyway.
The tool will draw you a nicely color-coded map of the disk layout and shows all the pertinent data for the filesystem of the image. It will even let you preview common file types if you need. The tool can also convert images between various formats, and spit out reports on things like bad sectors or corrupted files that have been detected. FloppoScope can handle everything from PC and Apple format disks, to Amiga, Atari DOS, and BBC Micro stuff. Oddities like various Sharp MZ machines and the NeXTSTEP format are included too. It works with both image and flux files, as well, so whichever way you captured your disks, it should work here.
We’ve looked at the importance of imaging remaining floppy disks quite recently. If you’ve got unpreserved disks sitting in your bedroom, shed, or study, consider getting on that as a matter of priority at this point!
