Howdy, I regularly use an external optical drive (OWC Enclosure, LG Blu-ray drive) with my mac mini. Recently, it started seeming to flake out -- it would show up as connected to the machine but would disconnect while watching a movie or burning a disc, or even while doing nothing. I tested with a second external enclosure and saw the same issues (at this point the drive never even seems to mount correctly any more). Same issue happened on my MBA, so I assumed it must be a bad LG drive inside the enclosure and ordered a new OWC slim USB 2.0 enclosure. Now i've been using the new OWC optical for a few days and am having the same type of issues again. Initially the disk drive always mounted correctly but after being plugged in a while it stops showing up in System Information/Disk utility. Sometimes if I reconnect it a bunch of times it will appear again, at which point I can watch a movie or access the disk. I can't help but think something is wrong here that isn't just the optical drives -- anyone know what might be causing this?
