It’s also worth mentioning that a Mac running 7.5.3 should also be able to write to a PC DOS floppy. Therefore, we need one more computer – in my case I had an iMac running 10.2 that I could run Samba on (SMB is the File Sharing for Windows option). However, Apple began to phase it out in macOS 11 (although it stopped being the default a couple versions earlier). Apple Filing Protocol was the standard way to share files for Apple products for OS 9 and earlier – it also became TCP aware and wasn’t just a broadcast protocol. There’s also a Sharing Control Panel where a username and password can be created and other machines can then mount the shared volume. My DHCP server didn’t assign an address dynamically so I had to do so manually (the Control Panels were under the Apple menu, much as System Preferences and then System Settings are today). The TCP/IP Control Panel probably looks similar to anyone who’s used a static IP in a modern system. Below are two ways I was able to achieve this: the first was a transceiver and the second a PowerMac 7200, which has built-in Ethernet. Getting Ethernet can be done via an Asante, a transceiver from Sonic Systems, or a number of different ways according to the model of Mac. Before I recovered data I used a write blocker on a modern Mac and made an iso of the raw contents of the drive – just to be safe. I could only make this work on a PowerBook 530 I had sitting around so that’s where I recovered data. So Disk Warrior 1, released in 1998, is a perfect companion. Macs could format 400k floppies until 7.1 and 800k and 1.4MB from System 3 until the end of the OS 9 era. Macintosh System 7.5.3 turned out to be perfect.Īnother thing to keep in mind is the density of disks. One way was through a machine that was early enough to have MFS support but late enough, provided there was an Ethernet or AAUI port, to access the Apple TCP/IP control panel. So off we go to figure out new ways to access MFS. I tried to get some of the virtual Macs online to read these, but the ones in browsers couldn’t and the ones like SheepShaver and Basilisk didn’t seem to like Ventura. For this, it might be possible to format a disk as HFS if the machine is new enough, but floppies were usually formatted as MFS automatically up until System 7. Now, if the disk is formatted as Macintosh File System (MFS), there might be a more challenging attempt to recover data. Once the volume is mounted, files can be copied around fairly easily. The output looks as follows (ymmv with disks): If you don’t know the /dev/disknumber, run hdiutil and check the bottom section – look for the new one to appear when you insert the floppy by re-running the command: These can easily be installed through homebrew if that’s on a computer:įrom there, a drive can be mounted using the hmount command: There is a collection of hfs tools that can be used to mount HFS on a Mac from Bob Leslie, at. If a volume (usually a floppy) has an HFS filesystem then it can be mounted on some Macs without much fanfare, but not the latest. This became the default format to format floppies in 10.6.
