Hi folks,
I have an old WD20EFRX drive that was used in a QNAP NAS and is now showing critical SMART values. The drive has become extremely slow, and the QNAP system can no longer boot from it.
However, when I mount the drive on a PC, I can still access the data, although copying files is very, very slow.
I was thinking of creating a block-level image of the disk (using ddrescue) to recover the data later, but I’m concerned the drive might fail completely during the process.
Here are the SMART values:
Code:
(base) marco@marco-B460:/media/marco/DATA$ sudo smartctl -A /dev/sda
smartctl 7.4 2023-08-01 r5530 [x86_64-linux-6.11.0-19-generic] (local build)

The drive also has over 62,000 power-on hours, and the Reallocated_Sector_Ct is in FAILING_NOW status with 1971 reallocated sectors.
Given these values, do you think it's worth trying to image the drive with ddrescue, or would it be safer to send it to a professional data recovery service?
Thanks in advance for any advice!
