Well I stumbled on a cause for the Infamous Seagate "Chirping" on the new Seagate ST1000DM003 1TB/1 Platter Hard-drives. I have had 4 drives do this and It appears,that on my system, the whole thing is attributed to the combonation of an HP DVD SATA I drive using a SATA II cable on the same SATA II mobo as the SATA III Seagate drive lol. I happened on this by accident while removing the DVD to quickly install a backup drive to transfer files from to the Seagate. Prior to removing the HP DVD, the Seagate drive was chirping and I had just bought it an hour earlier from a store front. When I removed the HP DVD and put a backup Hitatchi HD in with the Seagate the chirping stopped. I have not heard it for a solid 4-5 hours and the chirp was happening about every 3-5 minutes. Now in defense, both drives work fine when only one or the other is present but together the "chirping" appears and it is coming from the Seagate drive. It kind of makes sense. I spent 30min on the phone with Seagate tech support prior to stumbling on this cause and the only explination they could provide was the chirping was "power related" but I tried the drive on 2 different powersupplies. I'm lucky I stumbled on the cause. I haven't tried a fix yet but I'll try putting the HP DVD on a seperate power lead, replacing the sataII cable with a sata I and if need be just upgrading to a sataIII or sata II DVD. Was planing on getting IB sata III mobo but waiting till Haswell. Spread this around if possible. but now the dang drive is clicking.. honestly this is my 4th seagate drive since Jan. and they are CRAP. UPDATE: 40minutes later.... Well I replaced the SATA II cable on the SATA I HP DVD with a SATA I cable and YEP that did it! Confirmed. Having the matching SATAI cable has eliminated the chirping (and faint clicking has dissapeared aswell) on the Seagate sata III HD for over 40min.. Wow this one was a WIERD one. Technically, I didn't do anything wrong because the SATAI DVD had worked with that Sata II cable and another SATAII HD for years with no problems. Again, by themselves, each drive worked fine; but, when I added the SATAIII Seagate ST1000DM003 HD in with the HP DVD SataI on a SATA II cable the chirp happened. I don't think Seagate is aware of the cause because 30min with 2 techs today came up with no answer. All in all this is a good "better safe than sorry" lesson for making sure your cables match exactly with the devices standard even if a newer standard is backwards compatible. Peace.
