We had a drive go down in our Buffalo Terastation the other day and ordered the "same" drive from amazon. When we installed the drive it's appearing a bit too small to allow us to do a raid recovery.
Can someone suggest what we should do to ensure we get the exact same drive as the ones we have? Even though we ordered a drive that was ST4000DM000 we couldn't specify the 1F21 portion of it...and the new drive is a little too small.
Here's a screen shot of the other drives plus the new drive.
