Hi all, I just acquired a 2nd-hand Macbook Pro from 2012, and during setup it was v. slow, and kept freezing during spotlight indexing - disk utility told me the HD could not be repaired without formatting the drive. So I did this, and ran a repair which now said the HD was OK. I was able to boot to recovery mode and start installing an OS (Lion) over the internet, but it kept freezing during this process, or the "time remaining" count would get to zero then reset to read 1 hour 40 mins +-. Anyway after doing a hard reset to escape from yet another failed install attempt, the drive has disappeared. I can boot into recovery mode, but only Mac OSX Base System is showing, plus the Superdrive. Apple Hardware Test detects no problem. Is the HD broken? Did I do it, or was it on its way out already? All help much appreciated, thank you!
