When asked to confirm "write partition table" I press Y and the screen immediately goes to the one asking me to reboot for the changes to take effect, with no mention of any boot sectors or backup boot sectors; it skips that screen entirely.
Since the drive was still not recognisable after reboot, I followed this guide: http://www.bleepingcomputer.com/forums/t/481048/external-drive-showing-raw-data-after-removal-without-ejecting/ however when mounting the drive, I click the green Mount button for the bad disk, the mount window disappears for a couple of seconds, and when it returns, the file seems to still be unmounted, as the button is still green and says Mount. I can mount my internal drive no problem, as well as the USB I'm using to run PartedMagic.
Is there anything else I can do at this point? I have quite a lot of AV data I wish to keep, around 1TB
Edit: I am running Windows 7 32bit on a Toshiba Satellite L500. The Seagate Barracuda 3TB drive has been taken out of its original Seagate Expansion Deck case and put into an Astone ISO gear 481U3 dock. The computer sees the drive is connected but asks me to format it.
