Sorry, it's difficult to explain, I haven't noticed this on laptops with SSDS for obvious reasons - no moving parts, but I've noticed two laptops of mine which have mechanical HDDs, which are running perfectly fine, but I'm concerned whether it's an issue... when the display times out and the screen goes blank due to preconfigured settings in the power plan... the hard drive sounds as though it's powering down, but then a second later, the hard drive will spin up again and this seems to be a constant loop until the LCD is 'woken up' again... Is it normal? Any settings I need to adjust? Please note, no crashing occurs or freezing, everything resumes perfectly fine. Any input greatly appreciated.
