DS1815+ ; new HDD getting plugged out while repairing

[charvi]

Hi All,

I am new to synology box.

We are using 3TB * 8 drives on DS1815+, all the other 7 drives are fine; but i got one drive replaced as the older one had 1900 bad sectors
The newly replaced drive WD30EFRX-68EUZN0 (3TB Red) is getting plugged out while in repairing mode.
Unable to run SMART test on plugged out drive.

Can anyone suggest something?

Did you test the drive on a PC?

No, the disk was delivered to remote location directly where the synology box is physically located

Looks like the problem is either the drive or the sata port for that bay. No way but to test with another drive in the same bay, and what @Telos said, to test that 3TB drive in another device.
