- An obscure Apple Performa 550 recovery partition was rescued from an old Conner hard drive with a stuck head.
- The hidden partition, running System 7.1P6, booted automatically when the main system was corrupted, offering recovery options.
- The author used techniques like nudging the head and Kapton tape to recover data from the failing drive.
- The recovery partition contained a 'Mini System Folder' and a 'recovery' app, enabling manual restoration of system files.
- The feature was documented in Apple's tech notes and the book Macworld Mac Secrets, but data was missing until this find.
- The partition was confirmed to be functional in emulators and real hardware, though its exact creation method remains unclear.
