WOW! When I first started this thread, there was no reply for a while, and I stopped checking this Forum for a while because I got busy. OOPS. Even though it's a month later, I'll try to answer some questions.
How did I figure out the drive was powering down ?
I had the cover off the TiVo for a while after the upgrade. I'd simply hear the drive spin up accompanied by a long freeze. Once the drive finished spinng up, the TiVo would proceed.
Did it cure the stuttering ?
Based on other's experiences with this drive, I expected the occasional stutter. That I can live with. But the power-down is another story. Now that I turned the power down off, the rare stuttering doesn't bother me. I think these stutters are unavoidable, since this Maxtor 80 isn't an "A/V" drive. There was another thread discussing this in detail.
What causes the power-saver mode to be turned on ?
I think in my case, and it looked like most other people's cases, it was your PC's BIOS which turned this on. Most PCs I see have IDE power saver mode turned on in the BIOS by default. If you put an IDE drive into the PC, this will be turned on. I ran hdparm on both my A and B drive to get rid of the spin downs (the A drive was trickier to figure out, since it powered down much less often, and was quieter on spinup).
Is the power-saver mode persistant across drive power cycles ?
To be honest, I'm not sure. Since I ran hdparm, I havn't powered down the TiVo :-). It's been rebooted many times, but this shouldn't make a difference since the drive stays powerd up. However, based on other posts in this thread, it looks like it is a persistant parameter. I know that the power-saver mode stayed ON after many drive power cycles after I put it into my PC. So this either means it's persistant, or the default power-on condition. If the other posts in this thread are correct, I think it's the former, not the later.
How can I extract a tar file on the TiVo ?
CPIO is capable of working with tar files. Just un-bzip it (bzip is there too), and use the correct option (I forget what it is!) with cpio, and you can untar this. If you can't figure it out, you can always use winzip to untar it and just upload the separate files (not sure if Winzip handles bzip2 however).
Anyway, sorry it took so long to reply. I'm happy that a few have been able to apparently solve the spin down problem by using this utility. Have fun.

Well, I ran hdparm on both the Quantum and the Maxtor, and still my machine gives me the occasional stutter.
I think I will throw in the towel and live with it. It sometimes doesn't happen for days.
Anyone out there have any other suggestions? I have tried everything except restoring and doing a destructive write to the Maxtor.
