Western Digital Hard Disk Files Recovery Extremely Slow

Hi

There is a problem with my hdd. I am trying to copy the files from it now.
I can't attach it directly with SATA as sometimes the hdd will become very slow (i.e 100kb/s) and my windows 10 will become halted.
I am currently copying it over usb cable.
The speed is average at 4 MB/s, but sometimes it will dropped to 100kb - 300kb (it can last for several mins to 15 mins, but it still running). The speed will pick up again ( 4MB /s) whenever I turn off and turn it on back.

Can I know what's the problem with the hard disk?
I will request for RMA after I copied all the files.
Thanks



Data Lifeguard Diagnosis tool to check, this is the result I received "Test Result: FAIL" "06 Quick test on drive 2 didn not complete! Status code = 07 (Failed read test element), Failure Checkpoint = 102 (unknown test) Smart self-test did not complete on drive 2.

It can certainly be the drive. If you are getting some data off of it, about the only thing you can do is to just let it run until it completes.  I just went through this.

Probably not.  As you know, the drive is having issues.  Your best hope is to keep doing what you're doing, get your data off and RMA it.

Could be bad platters, drive head, actuator arm motor, etc....

The drive has indeed problems and thats why it is getting slow. I can speculate that the problem is caused by attempts to read the data from bad sectors.

te error claims that the read operation failed
that's the reason it trie to do rereading that sector -  = the cause of slowing down

if the drive is bad  - it can take a very long time recovering data -  so if you have a backup - use that instead

***i Always connect my drives for recovery operations by Sata, on a TEST PC, and let it run

Q. Can I know what's the problem with the hard disk?

A.  Yes, but your highest priority is copying the data off the drive.  Clearly it is in stress.  Consider that every I/O you get out of the drive may be the last.    So withhold your curiosity until you copy your data.

If you *really* want to know what is wrong, then the first pass would be manufacturer's diagnostics which are free.  They will give basic information.   If you want more technical details then you need some commercial software and possibly some test equipment.

But it doesn't matter.  RMA the drive and don't look back.   It is a waste of your time to learn the actual bad block numbers, and/or if the RPMs are off, or fly head is out of specs, or perhaps there is an ECC issue, or anything else .... it is bad and you are sending it back.  What do you care??

Try to connect this hard without USB cable(Direct to the motherboard of your PC)if the problem still exist " but i don't think so "
then your HDD has lots of bad sectors ,and you will have to use some (under DOS utilities to check or repair the damaged sectors) if this your issue tell me in order to send a link of some powerful utilities

Interesting, my answer gets no point even when it was me who told you - read attempts are slowing down your drive. Nobus just echoed my statement.
Sometimes I think my time is more value than someones problem.
