In an earlier post I described some problems I had been having. I initially attributed them to Pro Tools 8. My current guess is that PT8 was not my main problem. It looks like I was having a pretty common problem of a "Bricked" Seagate 7200.11 drive. Anyone with Seagate drives is well advised to check for firmware updates. The good news is that my data probably is still intact. We will see how easy/expensive it is to get to. (That may be the bad news.) There are DIY solutions out there that I'm not all that comfortable dealing with, though they don't look all that hard. I'll see what Seagate says in response to my email before going further.
