Seagate ST3500620AS trouble

[stoney1981]

I have a seagate ST3500620AS with sd25 firmware. When the drive is powered it sounds loke it aquires but is not recognised in bios or in windows. i have tried testing the drive on mhdd olso does not show but shows busy on that channel. Any help would be appreciated

I have tried performing a rom swap with another pcb but i have the same results. The heads in the drive sound healthy. I am really stuck. As this is a new drive i doubt many of you will have encountered this problem. If you have please let me know what you tried if succesfull or not. Thank you all

Please post terminal log.

At presant i do not have sufficiant updates to be able to do this as my de does not support this drive. De will be needed as the drive wont come ready. Even a seagate repair tool is not able to do anything with the drive.

If anyone know of how i can do a terminal log on a drive that wont come ready please let me know

had a problem with seagate drives
changed the pcb board for the right one

same problem does not pickup in the bios or windows


turns out that the main amp controller chip inside the drive
allso gets damaged when the pcb goes faulty.

your have to do a head swap

I have the same issue with 2 drives. The first (a mirrored volume on a server) failed just after a microsoft update (on black wednesday). The second drive failed a couple of weeks later. My first thought was that a virus may have wiped out the microcode, but the drive sounds like it is able to read the drive, although the system does not see the drive on POST. I was looking for a replacement drive online when I saw this forum. From what I read here it may not make sense to try to change the board. It sounds as if Seagate has an issue with these drives. Please let me know if anyone has any further information on this subject.

It's a fairly quick fix performed best by a pro. Essentially the drive "forgets" how large it is and needs to be corrected in the firmware. There are instructions floating around if you're comfortable with soldering things and using hyperterminal.

Please ensure your model number and serial number is affected by visiting http://seagate.custkb.com/seagate/crm/s ... 931&Hilite and then if your drive is affected please use the firmware update tool which can resolve the firmware issue on 7200.11 family even if it is not recognized in bios.

even if it is not recognized in bios.

since drccsc has raised a doubt, i should rephrase it as only for sd15 firmware issue. However i will reconfirm it when i have 7200.11 drive with firmware issue.
