mac mini disk drive missing
My mac mini works fine except the disk drive is not recognised in finder. It accepts a disk when i pop one in and whirs for a couple of goes and then spits it out. The usual restarts, remove power cord and resets for PVRAM SRC etc have been completed but still no disk drive. DVD player check box to open when a disk is inserted is fine. Disk utility opened and first aid completed with a green tick all in order.
I'm running OSx El Capitan, have Mac Mini mid 2010 with 2GB ram and 320Gb storage.
I think its just not linking to or recognising the disk drive.
All forums trawled through but nowt helps.
Any ideas please?
iPhone 3G, Mac OS X (10.7.2)
