Can anyone recommend a website with instructions for drive data restoration...or does anyone know how to do this? Looks like I have a failure
The good news in this though is that I have a duplicate model of the drive that failed, so perhaps someone can recommend a procedure for swapping parts so that I can mirror the failed drive using the functional drive.
I agree with the previous poster...depends what went wrong. if this is an internal drive it's possible only the partition table is damaged in which case software will let you rebuild it. On the mac Data Rescue II is a great software. For the PC, File Scavenger is an awesome software for data recovery.
If the problem is mechanical with the drive there are a couple of options. I had a drive which I could hear was attempting to spin however the spindles wouldn't turn (probably due to the lubrication gumming up caused by excessive heat). I did the freezer trick, which allowed me to access my data. (Just google "Hard Drive Freezer" for more details)
If you're completely wanting to go professional to recover your data, i'd be wary of many of the sites that claim they can do this as in many cases they are charging HUGE dollars to do one of the above mentioned methods. I would contact the Seagate company i365. They will give you a free estimate, provide free shipping and if they don't recover your data they don't charge you.
http://www.i365.com/data-recovery/index.html I'm not sure I'd attempt to do a parts replacement myself, as you can permanently disable the drive forever and you'd lose your 2nd drive in the process.
