So I recently installed an extra HDD for mass storage, and well... It's been formatting for well over a week now and I'm not sure how close it is to being done. Any suggestions?

That's wrong no matter what world you live in. It does not take a week to format any drive regardless of size or platform.

I'd stop the operation and then use a partition manager to delete any existing partitions on the drive, create a NEW healthy NTFS partition using the maximum allowable size, and then format the new partition.

If trying the above process results in the same problem, then I'd RMA the drive.


Did you do a simple format or did you do some odd command to wipe it 50 times or something?

Reboot the system, does the disk show in Disk Manager? If it does, right-click it, create a partition on it, and just do a quick format. If that takes more than a minute, contact WD support.

It can take up to about a day. 12 TB / (150 MB/s * 0.833) = 26.6 hours.

0.833 is the ratio of average to max disk speed, assuming a 2:1 ratio of track circumference between outermost and innermost tracks, integrated over the amount of data contained on each track. (The integral works out to 2/3 of the way between 1 and 2, and 1.67 / 2 = 0.833.)

Any format which takes longer means the disk is encountering problems reading/writing. If it's only slightly longer, that just means the disk took some time to map out a bad sector and substituted a reserve sector. But a format taking a week means the drive is dying. RMA it if under warranty, or buy a new drive if it's out of warranty. (And avoid the 5400 RPM WD drives - they have a head parking issue which can cause lag and stutters. That's the Green, SSHD, and most of the Blue WD drives.)
 
I just performed a full format, on an 8TB drive two days ago. Took six hours. No way it should take more than eight or ten hours, max, no matter what anybody says.


I 100% agree that if this is a used drive, it is probably shot. If it is a new drive, it probably needs to go back if you are sure you have removed the existing partitions, created a NEW partition and attempted to format THAT partition, but encountered the same issues. Formatting a borked up partition could cause similar issues as formatting a bad drive. Start with a clean slate by removing ALL existing partitions on the drive and creating a new one, then format THAT partition.
 


This isn't a 12TB drive (just 3), so at most 6h for a full format is about as long as I'd expect.
