Hi,
I have a Seagate Barracuda 7200.12 drive. Few months ago it suddenly started giving very low speeds (<3 MB/s). I thought it was a firmware problem.So, I upgraded the firmware from CC38 to CC49 and it was back to normal. A few days ago it again went very slow. I thought re installing the firmware would do the trick. But the firmware update utility said that it wont download the firmware as it was already updated. The drive is still accessible, but gives extremely low speeds. Is there a way out to repair/reinstall the firmware?
Thnx in advance,
Bluefog68

Why do you think the issue is a firmware problem? Probably some physical issue with the drive.

Look at the SMART data and see if anything shows an obvious problem.

Backup anything important on the drive.

@bluefog68,

I completely agree with Nick_CT. Since you say it is still readable, I suggest you backup what you need from that disk now. Just to add a comment:


As Nick_CT said, it's unlikely that firmware is actually the true cause of your problem.

However, have a read of this thread to see why there is much more to firmware repair, then you might guess...

Could you upload a HD Tune read benchmark graph?

If it is a flat line, then your drive may be running in PIO mode. If so, then your SMART data may provide an explanation.

@fzabkar,

Agreed, those are good things to check, Franc That hypothesis would seem to fit and would explain why the effect of the f/w update would only be temporary.

On .12 it is quite common. The problem can be physical or not but the fix is not by fw update. P.s. You may have 'something' in your pc that 'damage' the drive.

Hi,
Thanks everyone for the response. I thought it was a f/w problem because it started to work fine after the update. By the way, i have already backed up everything on the drive. I will soon upload the graph.

Hi,
I have attached the read benchmark test (HD Tune). HD Tune also shows that this device has unstable sectors(3) under "health" tab. What does this mean?
Thanks in advance
