SMART test failed
« on: June 21, 2017, 03:08:52 AM »
Hi,
I have 2 Western digital RED 3TB in my nas, in standard configuration for personal files storage.
When I try to move some specific files, not all,  on my pc via wifi the data transfer always stops at the SAME percentage, depending on the file.
Instead when i play the same files through DLNA i have no problem.
This problem in present only on one HDD.
I did the smart test, it fails, but i can't see what is the real problem and if i can fix it.

I download the "western digital data lifeguard" software but i can run it only on the local drives of my laptop and not on the NAS.

Can someone help me please?
Is there something I can do to fix it?

Do you have a back up of the data on this one drive that seems to be the problem? If so, then you could take this one drive out of the NAS and put it into the PC with the WD Diagnostic software and test the drive to see what is the problem and then contact WD support to probably have the drive replace.

I don't care about the data.
If i remove the disk from the nas e I plug it into a tower pc running windows 10, the pc will recognize the disk? Or do i need an external caddy usb to mount the disk?

Ok, then yes, put it into the PC and use the diagnostic SW to scan the drive. Report any information and results to the drive Mfr.

A few points.
1) If the SMART test failed then you should replace the disk - some SMART failures are critical while others indicate problems in the future (depending on its age you might get a replacement under guarantee).
2) If you plug the disk directly into any windows PC you are going to have problems - the NTFS of windows is totally incompatible with the Linux Ext2/3 of the NAS.   
3) Use a USB/SATA caddy/adapter to mount the drive - windows will generally say that it needs formatting but the WD diagnostic tools should be able to work with it.
4) Depending on which SMART attribute/s have failed you might be able to continue using the disk with limitations (we always replace a disk with any SMART failure because it is not reliable any more).

Note:  You can not repair SMART failures because they are information about the condition of the disk hardware including the electronics.  A SMART failure has nothing to do with the file system on the disk.
