Sounds like your HD is failing, or in a state of failing. If this the OEM mechanical HD that shipped new with your mid-2012

HD you can expect to fail typically 3-5 years



Now is your chance to upgrade to a SSD. Highly recommende you chane the SATA cable at the same time.

Thank you for your fast reply - and sorry for forgetting about this:


I replaced the HD and SATA cable a few years ago (August 2018) with:

SSD 500Gb samsung 860 Evo.

And

MacBook HDD Flex Cable (SATA cable?)


I first replaced the HD back then, it didn't solve the problem, but replacing the flax cable did!

Could the flex/SATA cable need replacing again?
