This month I started to notice my hard drives being a bit louder than the last time I paid attention to that. Both of them. Needless to say, I'm a bit concerned.
It MIGHT be because I unplugged a case fan that was making this horribly annoying grinding noise (will get a new one one of these days) that might have been masking the HDD noises. But I'm still a bit concerned.
Is anybody knowledged in this regard?
If it starts emitting bad noise, such as clicking and loud cracking in random intervals, you should get worried.
Do a health scan with Hard Drive Sentinel. Full scan.
any noise from an hdd scares me. i normally don't hear mine but my 175gb is starting to make some "odd" noises recently, so i backed that shit up quicksmart.
And like Stojke said, if you start hearing any "bad" noises that probably means death is imminetnt and immediate action is required if you need any of that data.
