I'm concerned that my HDD may be failing. It's a Seagate ST9320421AS 2.5" that's over 3 years old. Lately (probably the last month and a half or 2 months) I've noticed it's been sluggish... programs take longer to open, AV/malware scans take 2-3 times as long as they normally would, for no apparent reason. At the beginning of Feb, I powered on my notebook to be greeted by the usual BIOS screen, and then... nothing. The system just froze, stuck on that screen. I couldn't access the BIOS or startup options, and I eventually gave up and powered the system off. I tried again about 15 minutes later and it booted up just fine, but I created a backup of everything important just in case. I read that this is typical with a failing HDD, but it hasn't happened since. It's been bothering me though, so I installed HD Tune and under the SMART tab I saw one warning: Code: Spin Retry Count 100 100 97 4 warning I googled for info on this, but nothing conclusive about it being a FP or not. However, SpeedFan and SeaTools both show a completely "ok" status, no warnings or anything. Does it sound like my HDD could be failing?
