Very Slow External HDD

Anyway to bump up the speed?
I cannot watch movie from my Ext HDD anymore because they will no play smoothly, and music freezes when playing from there when it never used to.

I decided to move my music and movies to my internal HDD to stop this but it's taking up to 14 hours to transfer 4GB of data.
I have also just made a new computer, and it started happening with my old computer so I don't think I need to update my USBs or anything

  1. Try defragmenting the data on the external drive. Windows built-in defrag tool will do the job, but whatever utility you use to do it with, there must be sufficient free space on the drive for defrag to run. If it's heavily fragmented it may take quite while to defrag over USB compared to SATA or IDE.

  2. Your transfer rate works out at 83 KB/s. That's much slower than USB 1.1.

    ISTM that your drive may have bad sectors or a weak head.

    Try a comprehensive SMART diagnostic. Look for reallocated, pending, or uncorrectable sectors.

    I got 197 current pending errors and 198 uncorrectable errors from the HDDScan. What am I to do from here though?
  4. They sound like normalised values. What are the raw values of the attributes, especially the reallocated sectors?

    In any case it does sound like your drive has a physical problem.

    I'm not sure how to find the ram values?


    And als, it's not my pc that needs speeding up it's my External HDD. My PC is brand new
  6. The raw values are those long numbers preceding the threshold data.

    BTW, you can save your reports in MHTML format and then paste them into your next post.
