Could be a predecessor of mine. "20", "22" and "24" often indicate speed. Joe wrote: > Two drives in my desktop machine, neither retract by themselves. Nor does my TSSTcorp SH-S223B or my five Blu-ray drives. I had a few CD and DVD drives before. None did pull in on its own. I wonder where i could find owners of GH24NSC0 or DRW-24D5MT. > GSA-4160B [...] LTR-32125W Very honorable elderly devices, i'd say. > To be > honest, I thought that was a normal function of CD drives themselves, > not computer software. The drives have firmware which controls everything inside. Software on the computer sends SCSI commands (via the kernel's capabilities) to the firmware in order to trigger activities. The command for ejecting and loading is specified in SCSI volume SBC: 1B START STOP UNIT which has a "Start" bit and a "Load/Eject" bit. If Start is set, then a set Load/Eject causes loading. If Start is not set, then a set Load/Eject causes ejecting. If the drive tray has a motor, that is. Reco wrote: > It does [stay out], just checked it. It's ASUS_DRW-22B2ST 22 seems to be a lucky number, whereas 24 is not. Really strange is that Google finds nothing about the topic. It finds descriptions of drives - which don't open their tray, - which load but immediatley eject, - which load and eject in endless cycles, - which eject only if a medium is loaded. Didn't anybody suffer a finger injury while grabbing a medium in the moment when the drive decides to move in ? Or at least a justiciable shock ? Have a nice day :) Thomas
