Advertisements I have a TiVo Romeo OTA DVR with lifetime subscription that was purchased new in Sept 2018. We have filled the hard drive and just found out the external expander is no longer available. Can the internal hard drive be replaced with a larger capacity drive? If so, what is the max capacity it can handle? Is there a brand and model that TiVo supports? Or what brand and model fits and is compatible. Also if so, do I loose everything that I have recorded or can it be transferred? I have a repair contract with an IT company. Is this something they can install? Do they need any operating system to install on the new drive? And any other info you may have that I might not have asked. Thank you in advance, God bless.
