Please help:Slow Transfer Speed (Hard WD 1Tera)

Hi all
I have
WD My Passport Essential SE portable Hard Drive 1 tera USB 3.0+USB 2.0

the transfer speed of less than 10 MB \ second with USB 2.0
With that in the past, the transfer speed of 20-25 MB \ second

I’ve scanned hard through the program HD tune pro
The result was reassuring?

This speed map it seems the problem

and try to
write zero work through the WD Data lifeGuard Diagnostics

and

write zeros cannot complete with me (i don’t know why)

Waiting for your contributions and solutions

What is the solution with this problem

hanks in advance:neutral_face:

Hi, check if using another USB cable helps, also try connecting the passport to another PC.
