Hi
Recently I had to pop the drive out of my MyBook 3TB drive and use it for an urgent issue.
I now wish to reinsert it back into its enclosure.

However, when I have inserted it into the drive it only shows 1.8TB instead of 3TB! I didnt take not of any special partitions or partition types (MBR/GPT etc) before formatting as i assumed the onboard firmware would just reformat once it was reinserted.

I have tried wiping it, zeroing it out and other methods but still only get 1.8TB. Its like its hitting the 2TB limit but if its a wiped drive there should me no MBR setting etc. Or have i missed something basic?

Does anybody know how a drive should be prepared before reinsertion into the enclosure?

Thanks

I would use the diskpart “clean” command on the drive, then format it.

Be careful you choose the correct drive when using clean command, it is unforgiving if you pick the wrong drive.
