Hey all- So I've done some searching around these forums for advice on how to deal with my Mac Pro issues, but I haven't come across any posts as of yet that describe what I'm dealing with. So I'm running a Jan '08 Mac Pro (2.8), with an additional 4 Gigs of OWC RAM and an extra 500 GB harddrive installed, and another 500 GB external drive hooked up. Within the last couple of weeks (I only got the thing about a month ago), the computer hasn't been shutting down when I tell it to, nor restarting. It sleeps fine, but when it wakes up from sleep, sometimes applications don't work right away, or the machine will freeze applications open (though unresponsive), and no amount of Force Quitting will convince them to do so. On top of that, tonight the icon for my external hard drive disappeared, and I've tried shutting down (using the button on the machine, since it won't shut down via the software) and rebooting, unhooking it and unplugging everything, and nothing is getting that HD to get noticed again. I partitioned 30 GB of my main hard drive last night to install Windows XP, but I haven't done anything else differently, and the older problems didn't start occurring when I installed anything (otherwise I would have drawn conclusions about the RAM or extra internal drive). Sorry to be so long-winded, but what I really want to know is, should I take the machine back in? Get it fixed? Replaced? I don't know if this is a known issue, or if I should just wait for a software fix? If I were to take it in, what is involved with that? Can they transfer my files to the new rig? Thanks in advance to anyone who responds. This is driving me crazy (especially since up to this point, I've never had any problem with an Apple product)!
