    Just wanted to report that I successfully upgraded my Tivo HD using the WD10EADS drive. The instructions were perfect and exact. Thanks OP.

    I had two USB2/SATA enclosures for the transfer. Didnt bother doing the backup, but it still took about 3 hours and 45 minutes.

    Also, went to set the AAM option using HDDScan. Curious, I checked the drive's information via Identity Info and said AAM was already Enabled, but the current value was still 254. Decided not to change the value for now to see if drive works quiet enough without changing the value.

    Update: drive is pretty quiet even without changing setting.

    Just recently upgraded my home NAS from 1.5TB to 2.0TB due to a good deal on a pair of 1TB HDD. This left me with a pair of WD7500AACS-00ZJB0 HDD that were originally installed in the NAS. One idea i had to utilize these 'leftover' HDD is to use them for an internal drive upgrade on a pair of S3 that I own. Reading through the forums, I see that there is a soft reboot problem using WD GP 1TB for S3 internal upgrade. However, I am unable to find a definitive answer as to whether this problem extends to the older WD GP 750GB model above. I'm hoping someone in this forum can provide an answer.
    If I install these drives and they do cause a hang on a soft reboot, I assume hang can be corrected when it occurs by cycling power to the S3? If that is the case, I might be willing to live with it. The only downside appears to be that no scheduled recordings would occur after a soft reboot and a soft reboot should only happen after a firmware upgrade (can't recall last time I commanded a restart/reboot). Firmware upgrades on S3 are infrequent.

    An AAM value of 255 means disabled. Anything less means enabled, I believe.

    On the WD10EADS, there is a significant difference between an AAM of 128 and 254 from one foot away. You may or may not hear the difference from your seating location; that would depend on your distance, hearing, and room's ambient noise level.

    The 500GB and 1TB versions of the AACS-00ZJB0 exhibit the "soft reboot" problem on the TiVo Series3, so it's probably a good bet that the 750GB version does too.

    That's correct, but I would not discount the issue.

    If you your power goes out briefly, or TiVo installs a software update, then your TiVo will be stuck on the boot screen until you pull the plug. Unless your TiVo is connected to a UPS, I would probably just spend the $80-90 to buy a 1TB drive that works without that issue.

    Thanks for info. You confirmed my suspicions. Both S3 are on UPS, so I might try the upgrade on 'his' S3 and leave 'hers' alone (I wouldn't be able to tolerate the grief I'd get if 'her' TiVo missed some recordings 'cause I messed with it. ;)) I wouldn't buy a new drive just for this upgrade. Only reason I considered to begin with is that I hate to see good drives go unused and I have some drives to re-purpose.

    [Update] Can confirm that the WD7500AACS-00ZJB0 HDD, when installed as internal drive in S3, will cause TiVo to hang at Welcome screen upon soft restart/reboot. For now, I've decided to leave the drive installed to see if I can live with this anomaly. Since the S3 is on a UPS, I would expect only time the hang should occur is when TiVo pushes a firmware update (fingers crossed).

    Long time lurker, occasional poster...

    Just wanted to say a big THANK YOU for this thread. I just upgraded my TiVo HD to 1 TB and these instuctions could not have been more easy to follow. I do have experience with computer components, but this is a great FAQ for ANYONE.

    I did have my TiVo hooked up with the DVR expander, but i had one of those fail on me last year. It was still under warranty, so i got a replacement - but i'd much rather NOT have that extra point of failure. I'm just going to use the DVR expander for a backup PC drive (which i was in the market for anyway).

    Well......................my replacement drive from Western Digital finally arrived and I tried to install the program on it again. Guess What !

    I guess three is a charm because it seems to be working great on my FIRST attempt.

    Thanks again everyone for all your patience and help.

    Has anyone compared speed of the drives after upgrading? I know when I upgraded my Series 2 Directivos they seemed to get faster but that may have just been due to the jump to Sata with an adapter.

    I keep going back and forth about upgrading. I keep hoping the EVVS drives will drop in price so I am tempted to use the EADS since they are so much cheaper but I know I can tell the difference on my computer based on which drive I am accessing so I am afraid it will be the same on the Tivo HD. It already feels slower than the series 2 to me but it is tolerable. I can't imagine them much slower though.

    It is fairly well accepted now that having a high performance drive gets you nothing with the TiVo. Some people still do it but they are also those who put premiun in their Civic. Even when recording 2 channels and playing back another recording the drive is actually doing nothing for the majority of the time. A modern hard drive is so fast, even when acoustically detuned or when running at 5400RPM, that the the TiVo is not a challenge. It is not intuitively apparent but when you calculate the actual throughput requirements and the read/write burst speeds of the drive to/from cache it is the TiVo that can't keep up with the drive not the other way around.

    Automatic Acoustic Management (AAM) is more of method than a state. Since it is an optional feature of the ATA standards it has to be enabled by the manufacturer. So, if you have a drive with AAM enabled that means you can use software tools to adjust the setting. 254 is the default performance setting. 128 is the detuned setting desired for the TiVo. As you mentioned, that drive is particularly quiet compared to most drives in its default state but it can be quieted even further.

    Back when 1TB drives were much, much more expensive than now I intentionally installed a WD drive in my S3 even after it was known it had a soft reboot problem because I was able to get the drive for free (sort of like your situation). I agree with bkdtv, though, that with current prices as low as they are it is not the best path to follow. However, since we have both done it I can tell you it is very manageable, at least for someone who lurks on these message threads because you will pretty much be alerted to pending new software upgrades by discussions here so when I notice that I just start checking the system information menu before closing down for the night and if I notice a "Pending Restart" message (auto reboots happen in the wee hours of the morning when the TiVo is least likely to be used) I manually power down and restart. And even if I do miss it I will notice it the next morning (the S3 LED display will tell you it is trying to reboot even with TV off). This mysterious problem has no other repercussions. So, in my case the annoyance was worth several hundred dollars but I wouldn't do it again now.

    I may have to jump on one since I do have a $25 gift certificate to Amazon.

    That's a decent price, I just paid $101 for it from Amazon a few weeks ago.

    Yeah, I've been reluctant to jump because I'll have to lose all my recordings to upgrade. However at that price and since I had a $25 coupon burning a hole, I just *had* too.
    Or so goes the expiation to the hubby <grin>

    Interestingly, I used supersaver shipping & the order entered the preparing faze almost as soon as I placed it. That says to me their warehouse is slow. I've had it take 5 days to enter the preparing faze before.

    With WinMFS you should be able to copy over your recordings and season passes unless there is some limitation on the series 3/Tivo HD I am unaware of.

    EDIT: oh and where did you get a $25 coupon or did you mean gift certificate?

    Any attempt to do something one has never done before can be daunting prior to the attempt. There is little more frightening than the unknown. When one has made a moderate investment in an item and seeks to make modifications which it is known can result in causing the unit to cease to function, there is definitely a natural, "Oh, my!" response. With that in mind, I applaud anyone who decides to take the plunge, and have no criticism of anyone of limited technical expertise who decides the process is just too risky for them. That said, the whole process is really quite simple in execution. There are indeed several variables one must consider when upgrading and a handful of different actual paths one may take depending on one's preferred outcome, but once one has properly assessed one's situation and chosen an appropriate upgrade method, the actual process is really quite straightforward. In addition, while any process, and in particular any upgrade process can go awry, the number of ways a TiVo upgrade can fail are comparatively limited, and recovery from a failure in all but the most unusual cases is similarly straightforward. If one reads the first post in this FAQ carefully, posts any questions here to clarify anything which is unclear to the reader, understands fully all the prerequisites, and sticks to the process closely, then one is all but assured of success.

    I strongly suggest anyone of any level of technical expertise choose an upgrade path which includes a reliable and handy backup strategy. Indeed, my best suggestion is to remove and copy the primary drive to whatever primary medium is being used for the upgrade, then set aside the original drive for backup and safekeeping. Then if one manages to trash the other drive(s), or eventually suffers a drive failure, one can be back online in a matter of a few minutes.
