MyBook Essential all of the sudden transfering so slow it is almost useless

i am running windows 8 and until 2 days ago my external MyBook was transfering at over 25.00 MB/s. now i’m lucky if i get 1.00 MB/s. please help with ideas. i am so angry about this.

my 750 MyBook is working with no trouble however. very frustrating.

Try testing the drive

The OS should have little or no impact on the performance
