ArduinoFDC is a sketch that implements a floppy disk controller. It works with Arduino Uno, Leonardo, Nano, Pro Mini, Micro and Mega.

ArduinoFDC consists of three parts:

• A library providing low-level functions to allow reading and writing disks at the sector level as well as low-level formatting disks.
• Integration of ChaN's brilliant FatFS library to provide file-level functions for reading and writing files and directories in a FAT (MS-DOS) file system and a high-level format function to initialize a FAT file system.
• An example sketch implementing ArduDOS, a (very) small DOS environment for browsing a FAT file system as well as a low-level disk monitor to access sector data on the disk, including the ability to transfer whole disks or single files via the XModem protocol.

ArduinoFDC works with double density (DD) as well as high density (HD) disk drives. It can read, write and format 5.25" DD (360KB), 5.25" HD (1.2MB), 3.5" DD (720KB) and 3.5" HD (1.44MB) disks.

Rescuezilla is an easy-to-use disk cloning and imaging application that's fully compatible with Clonezilla — the industry-standard trusted by tens of millions. Yes, Rescuezilla is the Clonezilla GUI (graphical user interface) that you might have been looking for. But Rescuezilla is more than a Clonezilla GUI! Disk imaging is the process of making a backup of your computer's hard drive which is managed as files stored on an external hard drive, and 'disk cloning' is the process of making a direct copy without needing a third drive for temporary storage. For many people, the alternative open-source tools such as Clonezilla are intimidating and difficult to use, so Rescuezilla provides an easy-to-use graphical environment like the leading commercial tools, Acronis True Image and Macrium Reflect.

Rescuezilla can be booted on any PC or Mac from a USB stick, and has been carefully developed to be fully interoperable with the Clonezilla. This means Rescuezilla can restore backups created by Clonezilla, and backups created by Rescuezilla can be restored using Clonezilla!

A company that sells NOS (new old stock) floppy disks and floppy drives. Mostly 3.5", some 5.25" and even 8". Still sealed and recycled disks. Can transfer stuff from floppy disks en masse as a service. They also buy lots of floppies.

DiskScan is a Unix/Linux tool to scan a block device and check if there are unreadable sectors. In addition it uses read latency times as an assessment for a near failure as sectors that are problematic to read usually entail many retries (and bog the system down). This can be used to assess the state of the disk and maybe decide on a replacement in advance of its imminent failure. The disk self test may or may not pick up on such clues depending on the disk vendor decision making logic.

badblocks looks for fatal issues already happening and diskscan is for upcoming issues that can be fixed.

Also, badblocks is essentially obsolete in this day and age since the disks themselves will reallocate the data and there is no real need to map the bad blocks in the filesystem level anymore.

In the AUR. Works quite well, and sussed out a dying drive on Leandra.

A utility that lets you edit disks and recover data, including entire partitions. Supports multiple operating systems.

A poster of every extant processor, socket, module, and jack in use by computers today. Comprehensive and impressive. You can even buy a print of it if you want.
