Apple 655-0511, 4GB, 3.5″ Hard Drive. Western Digital WD Caviar 24300 Enhanced IDE (EIDE).
Pulled from a working Performa 6200, the Hard Drive has been thoroughly tested. It is currently running Mac OS 8.5.1 and while sanitized, does contain other applications that may no longer be available. If you would prefer a fresh install of this or a different OS, please contact me.
Note that the Hard Drive Carrier is sold separately.
