Hi, Amberbaum! Yes, the store guy also recommended SDD to replace the HDD, but after reinstalling, my laptop works well so he said we should wait and see for now ><;
Yes it was scary! It was fine last night, it's just that my laptop was lagging more than usual--I should've seen the sign and update Bermuda's backup then! The backup is in my external HDD I just sometimes forgot to update it ><;
I'lldefinitely take this as a warning and next time, if it corrupts again, I'll change to SDD QuQ this is the third time my HDD got corrupted without any clear reason. Fortunately this time it's not that expensive. I'll save up for that SDD!
