Thanks for the reply and email. Have to run out but will read a bit more tonight.
The drive that I removed is a seagate, but that part number is different;
ST3750640NS
There is also an EMC PN: 118032551 REV: A01
I am not sure if that helps at all, but I will take some time tonight to look at the doc you emailed (thanks again), and hopefully find a drive replacement sooner than later (and not $700 for a drive!) :)
