I am returning my Tivo w/a broken HDMI port for a replacement unit. This is a Series 3. The broken unit has a 1 TB DIY upgrade hard drive. The original hard drive was sold years ago.

I will be swapping out the 1 TB drive from the broken unit w/a 250 gb refurb, the same drive this unit came w/or close WD 250 gb SATA video/PVR ready. As far as I know it was never used in/a TIVO. It will probably be formatted w/FAT or NTFS.

I want to simply format this drive for the TIVO and ship it back. So this is not an upgrade but simply sending them back the unit the way I purchased it.

How do I do format the new drive?
