SUBJECT: ST3500320AS Barracuda 7200.11 SATA 3Gb/s 500-GB Hard Drive
I come back from holiday 2 weeks ago, switched on my computer and after the BIOS posted, nothing happened. My boot drive is a Seagate Barracuda 500GB 7200.11, firmware SD15. I googled this thread and concluded that it must be a sudden firmware issue causing the “breakdown” of my hard drive (I could still hear it spin up to speed but my BIOS reported no hard disk detected. I checked the power and SATA wiring with my other hard drives and these were detected as usual).
I contacted Seagate support Tuesday, TNT came at Seagate's expense to pick up the unit Thursday. Arrived at Seagate Amsterdam service centre Friday. Received message same day saying that it was a firmware issue and they were on the case. Unit arrived back on Tuesday. Put the drive back in my PC that night and it booted into my Windows XP OS as if nothing had ever happened.
Conclusion: very disappointed and worried that drive developed this issue in the first place but first class Seagate service thereafter. I use three identical drives and have now updated the firmware for the remaining two. Hopefully this will be the last time this type of issue arises.
Hope this helps.
