Hello! A few weeks ago my iMac started acting really weird; freezing on screensaver, getting really really slow to the point I had to reboot and freezing on the apple logo at boot. I ran disk utility but all I got was the "error reading drive, replace with a working device asap!@#" error message. I kept using it (mostly backing up my files) until it died completely. Now it just won't boot. I guess now I need a replacement drive, but I'm not sure what to shop for. I have the first generation of Intel mac, the 17 inch version. I'm thinking any SATA2 drive is going to work, am I right? Thanks!
