Hi,

I have a Seagate ST3300831AS Firmware 3.01 with a blown controller PCB. (Disk won't spin up when connected)

I purchased a new disk with the same model # but firmware 3.03. After replacing the faulty PCB 3.01 with 3.03, I was able to get the disk spinning up. No recognition by the PC's BIOS though. I assume the firmware must match exactly.

I am having trouble finding the 3.01 firmware on a SATA drive of the same size.

Three questions (assuming the drive will work if an identical PCB is used):

1) If I find a controller with the same firmware version 3.01 on a different sized SATA drive will a swap be effective?

2) If I find a controller from a IDE (not SATA) drive with the same firmware version will a swap be effective?

3) Can a ver 3.01 PCB be purchased from Seagate?

Thanks

yes my dear u can change the pcb of any other capacity with same make i mean if your hdd is sata then use sata pcb of same firmware it works dafinatly
