Yikes! One of our MacBooks had an optical drive failure (system can't find the disk and as it spins it makes unpleasant noises) and before I could get it fixed,,,, the Hard Drive went down! At start up we see the folder with a question mark. Applecare expired a couple of months ago! Here's what I tried: Used Target Disk Mode to access the HD - it can not be found (does not appear in Finder) Took the HD out- then popped it back in to see if it had become unseated. No luck. Next Steps? It looks like I am going to get a new HD, then have a local shop replace the optical drive. Here's where I can use some advice / experience: Will the shop have any problem with the hardware install on a machine with a clean (non formatted) HD? I imagine not, but curious. Can I format the HD and load OS X before popping it in? That way I can drop off a working machine at the repair place! Once I remove old HD- are there some simple data recovery options, places to start? (this data recovery stuff is a new problem for me! All the other machines are backed up, 'cept this one!) Any experience with this stuff will be appreciated, and richly rewarded with many thank you's and internet peanut brittle!
