So my 5 year old external hard drive started shitting itself by constantly connecting and disconnecting, followed by not being able to be read on occasion. I took the cover apart and removed the adapter that allows it to connect via USB and connected it to a SATA reader. Windows said it needed fixing once it got connected, but after a scan it determined nothing was wrong. It seems I may be missing some files but there so many I cant confirm. What I have noticed is that a few images have this blue highlight on them, which were not there before. Is this a sign of its end, is there some way I can save it, or should I order a new one and transfer what I can to it?
