Linux Raid Issue

[Oh_BoY]

Hello There,

I'm using Raspberry Pi 4 (4GB) for my lan NAS.

 

I have installed the 2 newly purchased Seagate Expansion Drives (1TB).

 

I'm using mdadm it starts resync of drives but when it reaches to 5-6% the one of the drives fails and the details shows sdb1 is faulty.

 

can i use the drive after formatting or else any other options are there which can i use without purchasing a new drive.

 

Spoiler

i have a suggestion install openmediavault on your raspberry pi and setup the raid in there or if you dont want install omv use parted or gparted

Return the drive/get it replaced. Maybe try it on its own somewhere else first, could also be a power supply problem. A Pi4 will probably not be able to properly power 2 spinning drives without an additional power supply/circuitry.
