I have a sata hard drive from an 07 iMac. It was the system drive and today I got a filesystem question mark when booting. I have already swapped the drive and have the machine back up & running with a backup from 15 days ago. I would like to now go into this drive and try to recover the more recent data. What I have tried: Plugging into an external sata interface via usb and it DOES spin up macos recognizes it as a 2tb drive but no file system (this is incorrect, it is a 250gb drive) disk warrior does not recognize spinrite does not recognize data rescue 3 doesnt retrieve any information. I tried a quick dip in the freezer with only the same results. It seems like since it does spin up that I should be able to read something off of it at a low level. Any thoughts?
