400gb HD in TCD24004A

[SmBrainBgAmbiti]

I was wondering if my SAS2 TIVO would accept the 400gb HD. I originally had a 120gb with a LBA48 kernel, then I upgraded to 160gb with MFSTools backup & restore. Now I want 400gb-I got 2 drives for $109 each, New Seagate with 5yr warranty. My real question is I know I have to modify a partition (swap?) to be bigger, but I can not find the thread, and whether MFSTools will still work with this large of a drive. Can someone help with the missing details or links to answers?

Thanks,
John

There are several possible problems. First of all, you can expand to a larger drive only once due to partition limitations. This is not a problem if you are willing to lose your recordings - simply expand the original drive to the 400 Gig.
(There are workarounds, but they require a bit of work and a little luck).

Second, there is a flaw in mfstools which requires a minor work-around if you are creating a partition greater than 274 Gig. This is easily handled by using the -r 4 switch while restoring. And lastly, there is the swap size problem (http://www.dealdatabase.com/forum/showthread.php?p=233561).

You can get your 400GB working in you Tivo with mfstools. You'll need 200MB for swap. I set mine up with 512MB. When you issue the mfsrestore command:

mfsrestore -s 127 -r 4 -zxpi /mnt/backup.bak /dev/hdZ

change -s 127 to -s 200. The following is assuming you have booted with the PTVnet lba48 Cd. After the restore is completed issue the following command:

tpip -s --swapped /dev/hdz

The PTV cd has the tpip v1.1 utility on it. You could also download tpip v1.2. The command for it would be:

tpip -1 -s /dev/hdz

Interestingly enough I found this bit of information over at the TCF forum in the weeks before I hacked my Tivo. Scroll down to post 549. Here's the link:

I have 2 PTV CD's one is 4.0, the other is 4.01. One is byte swapped, and the other is not, I am not sure anymore which is which as I failed to mark which was 'BS'. Is there an easy way to tell??

Hook up the TiVo drive as secondary master on your pc after disconnecting your Windows drive. Boot from one of the cds. From the command prompt type
pdisk -l /dev/hdc. If it displays a partition table you've got the right cd. If it reports an incorrect signature you've got the wrong cd. If it reports no such device, you didn't hook the drive up properly. If it boots to Windows 2K or XP you forgot to disconnect the windows drive and are in big trouble.
