So I've got 2 hard drives installed, one 500gb ssd (which has my OS, dev programs and games) and a 3tb HHD which I basically store old photos/completed art on. I've noticed the transfer between the 2 is taking an astronomical time, and sometimes when I've clicked the pc while it's trying the whole of windows or file explorer itself crashes. So I've started trouble shooting and have ran the disk check on them(Note my hhd isn't particularly full I don't think I've even used 500gb on it). The ssd was about 10 mins, the hhd has been going for 7 hours (it's said 8 mins left and stayed at the same spot for about 5 hours). I know it could take several hours or even days but I'm wondering at what point do I give up (and accept that my drive is probably failing, so I can try saving files). I'm planning on leaving my pc on scanning overnight
