Hello. First I apologize in advance for thread that may have been already created by someone else Naturally i was looking for. My problem is as above. Windows 10 pops up "Windows detected a hard disk problem (...) Start backup process (...) Ask me again later" "which disk is failing..." So, what to do? S.M.A.R.T. shows no errors. No critical attributes raw value changed. No pending / remapped/ hidden sectors/ bad sectors. No damaged disk blocks, S.M.A.R.T status ok. HDD is healthy, works properly. Only one attribute has status "attention" - C7 Interface CRC Error Count - Curr. 100, Worst 100, Thresh. 0, data 79. Last few days i was manipulating with arrangement inside of PC case. I have new PS and SSD. Could it be because of this "C7" so it's nothing, or maybe some serious crash coming up? Please help.
