My Seagate Free Agent hard disk stopped working when I connected it to a Blu-ray disk and now it keeps showing i/o errors. It being detected and the drive is shown, but I cannot access the drive, or even run Chkdsk on it. I can safely remove it and but not access it.

Is there anyway to restore or access the hard disk?

    By the sound of it, there is a problem with the data on the hard drive, rather than with the device itself. What I suggest below will wipe the contents of your hard drive! Continue only if that's acceptable to you.

    Right-click on it in Windows Explorer ("My Computer") and format it. You should then do some testing (copy a substantial amount of data to it and copy it back) to ensure that it is working properly.

    If you get an i/o errors after the reformat, the drive is probably on its way out (you can test it with suitable software, such as that listed at http://www.techsupportalert.com/best-free-hd-health-monitoring-and-diagnostic-programs.htm).

    If you can't reformat it, you could try to remove the existing partitions and recreate them. I don't know which version of windows you are using so will not go into the detailed instructions, but you can google "how to partition a hard disk in Windows " and you'll find plenty of articles on the subject.
