Hello linkhunter. I’ve saw some cases where Synology will list the SMART on a drive as a failure based on the load/unload. Synology sometimes considers this a “failure” even though the drive is fine since it is just reading this one attribute. Sometimes you can disable this option in the SMART of the synology. We do have a utility for 2.5" WD Red drives that may alleviate this issue and I included the link below.

Your computer’s motherboard/BIOS may not support support a drive over 2TB and that is why DLG lists it as 1801.76GB. Also, when DLG says that “SMART Status: Not Available” it tyically means that it can’t properly read the drive on the controller. This usually happens if the drive is in an enclosure (USB, FireWire, etc) or if the SATA controller on the motherboard is set to a mode like RAID or one that supports RAID. One thing that you can try is to make sure that you have the latest version of DLG Diag when testing the drive or try the drive on a different computer.
