Hi, my S3 TiVo (original S3, not the HD, or XL, etc.) with a 1TB internal and external 1TB eSATA drive could not get program data (the ugly hideous S03 error), so I installed a new 2TB hard drive to troubleshoot. Eventually I discovered that increasing the swap space to 2000 fixes that problem. Apparently the guide data was getting too huge and the TiVo had no place to put it... I spent a week filling the hard drive with HD material to test the Hard Drive and discovered with TivoPlayList that there is only 288 (sometimes 289) HD hours recorded when the disk is full, not 317. This is obviously the difference from SuperSize which I turned on with WinMFS. Is there a way to tell if SuperSize is enabled or is there a sequence of when it needs to be enabled to get SuperSize working correctly? Checking the drive again with WinMFS reports "Supersize is already enabled" message. Thanks for any help!
