Re: Is it possible to improve transfer rates?
I sympathize with you about WD drives -- I had two of them, each only a few months old, fail on me within a two-week timeframe.
As to the drive speed, as long as there are bad sectors that are in use, the drive performance will be very s...l...o...w -- because it tries over and over again to read a sector until it finally gives up and moves on to the next one.
I tried to rescue data from my failing drives but the utilities all gave up early in my attempts with "too many failures".
Ubuntu 16.04 Mate, Mint 17.3; MS Win 8.1, MS Win10 Pro.
Will not respond to PM requests for support -- use the forums.
