Seagate ST31500341AS 1.5TB

I decided to call Seagate to request the firmware upgrade. I called around 8:00 a.m. Mountaint Standard Time. I was on hold for just shy of 20 minutes. The gentleman with whom I spoke was quite courteous and acknowledged that problem with some of the 1.5TB drives. He said it was due to the drives radomly going into diagnostics/testing mode. He said the firmware upgrade resolves the issue. I gave him the part number, serial numbers, and current firmware info for all three of the drives I bought from Amazon. Less than 1/2 hour after I got off the phone with him, I had received the link and certificate number for the firmware upgrade. My original firmware was CC1G. The upgrade is for CC1H. I was hoping to receive firmware for CC1J, which is the firmware on the drives I ordered from NewEgg. Oh well. I'll try upgrading the firmware from CC1G to CC1H later today.

Oh, incidentally, I was talking to the Seagate rep about the warranty issue. He told me that if a drive is sold as OEM, then the retailer/seller provides the warranty, not Seagate. Thus, he warned me, if buying an OEM drive, pay careful attention to the warranty information. He told me the drives I had bought from Amazon were being warrantied by Seagate (thus, 5 year warranty); however, because I did not have the s/n for the drives I bought from New Egg, he could not provide me with the warranty info on those drives.
