Just bought 5 used 8TB Ultrastar drives on ebay for only $35 each. Heck of a deal right? Checked smart info and everything looks good. Of course i know it would be a good idea to do a complete scan for bad sectors but I don’t know the best program for that. Ideally a free win10 program that i could test all 5 at once connected to one pc
you need to do a full read and write on the disk. use a program to write the disk full of 0s and then verify read. UNRAId does this with its preclear function.
