Hello all... I'm a new TiVo user. I recently found an older S2 single tuner at a pawn shop. I decided to buy it (got it REAL cheap!) with the intention of upgrading the HD with a 200GB Maxtor (ATA) drive I have. So I used WinMFS Beta Build 4 to copy the OEM 80GB WD to a 120GB WD I have. I wanted to make sure I could get this to work before I pulled the 200GB Maxtor out of my Windows Home Server machine. The 120GB (and 80GB) works just fine but the 200GB tiles recorded videos and live shows. The "settings" screen shows a maximum recording time "up to 219 hours" with the 200GB drive. So I know the TiVo sees it's a bigger drive. I was thinking maybe it might have been some kinda BIOS type deal only able to read "up to" a certain size GB like older computers had. I also tried resetting and clearing the unit hoping a fresh delete/format (or whatever the TiVo does) would help the file system, but it's still tiling. So for now I am using the 120GB. The TiVo has the current software version 8.3-01something or another... BTW... The build date on the machine is 17-OCT-02... Model number TCD240080... It also seems that this TiVo's prior owner had purchased a Lifetime Service contract for it. And did I mention I bought this for $30 plus tax? I searched the forum and couldn't find a thread with a similar issue. If more information on my side is needed just let me know and I'll post it.
