So, I have a WD MyBook Essential 1TB (USB 2.0) external drive with bad sectors (HD Tune says: reallocated sector count: 192/192/1400). I tried HHD regenerator, zero-write, nothing works. Can it be fixed or should I just replace it? Is it possible that the error is from SATA-to-USB adaptor inside (the drive inside is WD green wd10eads)?
