Hi guys, I'm not new to macs, but I do have a question I don't know where else to put it. Anyway, so here's my situation. I have a 2009 MBP, 2.26 GHz, 2 GB ram. A few months ago I upgraded the 160 GB harddrive with a 320 GB Western Digital Scorpio Blue. All went well, until this morning when it 'experienced some shock', at which point it became very slow and unresponsive (but did not crash). I force restarted it, and every time, it will go to the grey Apple logo, and get stuck there. So, what I have tried. I have turned it on and off several times, unplugged it, (and I took off the bottom and disconnected that battery as well. not what I removed the bottom for, but figured it wouldn't hurt), tried starting up from a disk (takes a little bit to load, but will get to the install page), tried starting up from my Time Machine backup (it took a long time with that too, and never got anywhere), and I've gone to disk utilities. Verifying and repairing disk permissions it did without complaint, but when I went to verify, and then to repair the disk, both times it gave me an error For repair it said: Invalid node structure Volume check failed. Error: Filesystem verify or repair failed. Verify all the same except instead of invalid node structure it said Invalid record count So, I'm pretty sure my (warranted) HD is bust, but I just want to make sure, and be sure that nothing else is broken as well.
