It has been showing the symptoms since a nice while, like not being detected at once, or slower access, not being able to copy some files(the copy process is stuck) and stuff. I thought it was my PC having some problems with USB 3 and blablabla, but now I am sure it is my HDD.
So how can I tell what exactly is happening? I cannot complete the WD Diagnostics due to some error at the start of the test.
Will it be a physical damage or just some sector/logic-based that can be fixed after formatting the drive?
Please ask for more information if needed. I am going to run some tool like DDrescue to copy all the data that I can, once after I get some assistance here,
