Here's someone who tried to push it up to 1600GB via an external raid. He mostly got it to work, but see the ss5 screen shot halfway down the thread. We haven't heard back in a while, so I don't know how it worked out for him in the long term. Seems that 1TiB may start to hit an integer overflow boundary. Two 500GB drives should be just under that though, so I suspect it would work out ok. Two 400GB drives are known to work.Rob00GT said:

Interesting.
I'm trying to upgrade a S1 with 2x Seagate 500GB drives to give 1TB, but it doesn't seem to work
1x 500GB is fine, but when I add the 2nd (mfsadd -x -r4) the TiVo fails to boot up at all - won't even get to "Powering up...". I thought it might be a PSU issue, so tried powering the HDDs from a PC, but again no joy. Then I powered one HDD from the TiVo's PSU and one from a PC and (after a very long delay) it booted to just after "just a few seconds more" then rebooted and stuck at "Powering up..."
Thinking it might be a partition-size issue I tried re-doing the mfsadd of the "B" drive without LBA48 support (to give a 137GB partition) then rebooted under LBA48, rebuilt the partition table and re-ran mfsadd to create another partition to fill the drive. All looked fine and mfsinfo reported the partitions as expected (with the 2nd partition on the "B" drive smaller than I know works with a 400GB "B" drive) - but the thing still refused to boot in the TiVo regardless of how I arranged the power cables
Any ideas? My next step will be to try a 500+400 configuration, but I'm worried about 2 things:-
1. If there is a PSU-loading issue with these drives (Seagate 7200.9 ST3500641A) compared to the 400GB Seagate 7200.8 drives that work just fine.
2. If there is some kind of 1TB limit as mentioned above.

Does this mean I'm the first person to try 2x500GB drives in an S1 then?
OK, here's what I know:-
1. Both plugged into the same S1 TiVo PSU (sounds like both drives spin up) - nothing onscreen for about a minute followed by "Welcome. Powering up..." for ever.
2. Master plugged into a 2nd S1 TiVo PSU, slave into the target TiVo, both powered on around the same time - same as 1).
3. Master plugged into the same or a 2nd S1 TiVo PSU, slave into the target TiVo, master powered on after slave has spun up (my attempt to emulate SmartStart/PowerTrip function) - nothing onscreen, ever.
4. Master plugged into a 2nd S1 TiVo PSU, slave into the target TiVo, *slave* powered on after master has spun up - same as 1).
5. Slave plugged into either TiVo PSU, Master into the target TiVo, *slave* powered on anytime after master (1 second to up to just after "Powering up." message) - TiVo boots to "almost there..." then screen goes black for about a minute followed by a reboot and "Welcome. Powering up..." for ever.
So, option 5 seems to get the closest, but I'm guessing the TiVo doesn't recognise the slave drive then reboots because it can't find it. Starting the master after the slave never works at all.
FWIW, I have also tried a Seagate 500GB + a Seagate 400GB and get the same results. However, a 500GB master + a Seagate 300GB slave works just fine (I haven't tried it the other way round). I have also tried powering both drives from a PC PSU and get the same result as 1 or 3 (can't remember which, but it doesn't work), and have tried all the 1-TiVo options in the 2nd TiVo just in case the 1st TiVo's PSU is defective - same results.
From the above, does it sound like a PowerTrip/SmartStart will help? It appears that staggering the drives (slave then master) manually doesn't work in this scenario. Some people have hinted that maybe IBM drives "look" for each other at startup which is why they don't work with the PowerTrip - could these 500GB Seagates be doing the same?
Interestingly, it appears that the S2 TiVo PSUs have a slightly higher rated power output than the S1 PSUs, so maybe this is why people have been able at to use 2x500GB in an S2? Is there any way I could use a S2 PSU in a S1?

I don't think there's room for two PSUs in the same box
What I'm hoping is that I might be able to swap the S1 PSU for a S2 one which would be able to power the two drives OK.
Does anybody know the model number of the PSU in a TCD540040? That's the machine that Weaknees have working with 2x500GB Seagate drives.
