My Seagate drive went bad suddenly, and noticed that the SMART Error was ON. The drive is visible in Windows with all the partitions Ive created but they are not accesible. Before going into Parted Magic and follow the advices on the link http://www.bleepingcomputer.com/forums/t/481048/external-drive-showing-raw-data-after-removal-without-ejecting/ I decided to use SpinRite 6.0 to see if was able to access it later but had no luck.
Then I followed the guide you has recommended using Parted Magic but when performing either a Quick Search or Deeper Search using Testdisk, it shows that there is no partition found. Tried to run the Drive Health but it just dont show any status. When trying to mount the drives using the button at the taskbar, nothing happens at all. I open Filemanager and try to mount it but was unable to, not even the working drives, maybe Im doing something wrong but not so sure.
Then I tried to mount it using the Terminal Console but still it gives me error trying to mount it. Anyways, then I boot to my Windows 7 OS and used Seagate Recovery Software tool, it failed the Short DST Test. Havent run yet the Long test to fix the errors cause it was saying there was a risk to lose all data.
Tried to use iCare and EaseUS trials to at least see if they were able to see the information inside the drive but was not able to detect any file. Ive found some info about another tool called Ubuntu Rescue Mix that creates a complete image of the Raw Drive but havent tested yet cause it requires me to have the Bad Drive, the Destination Drive that has to be the same size and another drive with Bigger HDD Size than the Bad HDD but I dont have that yet so im kind of stuck right now.
Any idea how can I fix this? I change the drive letter of the bad drive in Windows and now is displaying a message to format it.
