After two years, my Seagate 750Gb (product ST3750330AS) suddenly became non-communicative.
It still apparently spins, (due to usual slight vibration) and is slightly warm, indicating that it is powered up.
But it no longer appears in the PC's BIOS (I have two other hard drives there).
I removed it, and attached it to an external USB enclosure, and once plugged into my other Windows system, it was not detected there either.
It is not my boot drive, but has a lot of data on it in several partitions.
Could this be a firmware error? The firmware is SD15, and I see from this website there are a "few" problems with it.
Is it possible to flash this drive, even though the BIOS does not see it?
Otherwise, how can I possibly recover the data?
Is it still under guarantee? I recall Seagate had 5-year guarantees on most drives-
This one was has a date code of 09073 and was purchased by me on 01-21-09.
What is the replacement procedure?
