Hoping someone can help as it has been a while since I did this. In the past...my Roamio Plus units had their drives upgraded to 4TB and one with a 6TB drive. Problem is...I can't remember how I blessed the drive prior to install so I was able to use all recording space instead of being stuck at 2.8TB. Remember something about an adapter and a program. Any help would be greatly appreciated as I now have another plus that I would like to upgrade the hard drive for. Thanks.
