I have a Lacie Thunderbolt SSD USB3.0 256GB hard drive, the one with the bright orange bumper to protect it from falls! The USB3.0 lead i've been using has been a little funny lately, occasionally saying 'device disconnected' when nothing has been moved or unplugged. This morning it happened, but the hard drive just wasn't detected by the OS (10.8.4) again. Whether I try connecting it with the thunderbolt or USB 3.0 lead it doesn't register in finder or Disk Utility. Taking the drive apart (interestingly, the do not break this seal or warranty is void sticker was cleanly cut already) and connecting it to a USB 2.0 external caddy. The following message appears. "The disk you inserted was not readable by this computer. Initialize, Ignore or Eject." I chose ignore. Both Disk Warrior 4.4 and Data Recovery 3 can't actually see the drive so can't do anything with it. I followed terminal 'diskutil' prompts and managed to get it listed as attached but no other commands would work as it said 'no in/out' or words to the effect that the drive couldn't be read or written too? Can you think of anything I haven't tried to save the data? ---------- I meant to add there is power going to the drive and the access light is blinking!
