Sorry for the long silence. As I posted last time we found a support tech named Dustin who genuinely seemed interested to help- I spoke with several prior who were just happy to get me off the line and had one hang up even though I was being very cordial.
We returned 13 drives to Seagate, all were 160Gb model ST3160815AS with various Firmware. We got 13 replacement drives that were 250Gb in size. It was nice to gain size but at the same time we had hoped for new drives instead of "Certified Repaired". I paid full price for the drives when I bought them originally and I paid full price for the WD drives I have replaced the failing Seagates with that were in my clients' computers. Basically we have used these replacement drives IN HOUSE for various tasks including a RAID 5 setup for a new server (since I won't sell a "certified Repaired" drive to a customer). Two days later the array needed rebuilt because one of the 5 drives was toast already. Anyways the replacement drives are the same thin design as the 160's we sent back. Dustin explained that the design was their "NightHawk" series although the labels all say Barracuda. I was told that the replacements would be standard height and that they did not exhibit the problem I had been experiencing but the replacements were the thin style and do very much still have similar issues.
In the mean time I had my 750Gb Seagate fail in my personal machine but was able to get it copied over to a 500Gb WD in time. Another in-house system began to blue-screen on it's 500Gb Seagate and you will never guess what the solution was? Yep it was copied over to a WD drive. My system is an Intel Quad Core and I had not experienced the drive failure on anything but an NForce Chipset before. The other in-house system I mentioned has an NForce chipset.
I had a client bring a system in today with an Asus Crosshair board and a dead data drive- about 200Gb worth of ACAD drawings gone with a crapped out 500Gb Seagate. I cannot get any of three systems to even see it, whether connected with a SATA cable or with an external USB interface. Nothing. It spins fine but it is not detected. I don't want to hate Seagate but I sure do want to get to the bottom of this. We need some help to discover why this is happening. The Drive that failed and was brought in today was a model ST3500320AS, Firmware SD15. It is a full height drive...
Anybody have any good news to share?
