    IMO if you have a drive starting to die the chances of bad sectors are also high.

    Therefore in the time you have your drive spinning, the best thing to do is dd_rescue the dying drive onto a new drive. dd_rescue can skip errors replacing them with zeros, whereas the regular tools will likely hang/timeout

    You don't know how many bites at the apple you are going to get with this drive so best to get as much off as you can as soon as you can.

    Once the data is on a new drive you have the luxury of taking your time.

    Thanks everyone for the help. I tried to clone the original internal drive. I was able to get it up and running along side the 1.5TB Seagate but it wouldn't stay running long enough to copy the drive. I was however able restore the backup I made of the drive a few days ago. I expanded the drive using MFSAdd and ignored the warning about the drive being larger than 1TB and told it to expand anyway. Now the drive is back in the TiVo, up and running. It said I have, I think, 237 Hours of HD.

    I lost all the recordings but it was great to not loose the settings, season passes, ratings, etc.

    Thanks again to everyone for the help.

    Ever since at least version 11.0k of the S3 software, you can ignore the partition too large warning, but to successfully max it out with a 2TB drive, you have to copy, via WinMFS, and turn down the offer to expand, and then expand via mfsadd as a separate step.

    unitron:
    Regarding expanding to a >1TB drive in a S3 (original) using WinMFS, I've seen you write "you have to do the expand as a separate step instead of accepting the offer at the end of the copy/restore, for some reason" in several messages, but haven't been able to find any explanation.

    I didn't see your advice before accepting WinMFS's offer. The resulting partition map looked reasonable (1.6T in the last partition). The TiVo rebooted, seemingly without incident. It now reports 318HD hours capacity. The first attempt to load new program data failed (from what looked like a network problem), and the second attempt is taking a long time, but it is loading now.

    Can you explain what you think goes wrong when accepting the offer to expand? It looked like it just ran the same "Mfsadd" work that I would have done later.

    If there is something subtle wrong, I can certainly repeat the copy, and I'd rather do that now than later. But it doesn't look to me like anything is wrong.

    Thanks for all your help!

    If it worked for you then it is fine. What happens for many people is that if you say yes to expand right after you copy, WinMFS just sits and stares at you and does nothing. So by saying no to the expand right after copy, then use MFSAdd to expand, it works all the time. That's all. Nothing more. Why it does that, nobody knows.

    But MFS Live seems to have a problem with expanding as part of a copy and expand sometimes as well (although I'm not sure if it can handle 2TB drives to begin with.)

    I don't know if the problem goes all the way back to MFS Tools or not.

    And another WinMFS trick to look out for is if you're doing a drive to drive copy it'll sometimes sit there and appear frozen, but it's actually working and you just have to give it some time and realize that amazing computer accuracy does not extend to progress bars.

    That last partition wasn't shown in the partition map (that you get when you click mfsinfo) as an Apple Free partition by any chance, was it?

    MFSLive does not handle 2TB well. It can be recompiled to handle 2TB drives once some variable declarations are modified to a double word length. I have been slowly working on this as the amount of time I can give this project on any one day is very limited. Oh well. If work just would not interfere......

    I had no problem using mfslive-1.4.iso to expand a TiVo HD 2TB drive, after dd.

    Not all functions have problems with 2TB drives. I noticed you used dd to copy the drive. Have you try copying the drive with MFSBackup/MFSRestore commands?

    This post is so timely as I'm right now copying a once-expanded 1TB drive in a 652-model to a 2 TB drive using WinMFS. I started last night at 11:17 pm and at 9:52 am this morning it was still copying. The progress bar ( I know I can't trust it) was at about 60%. Both drives are hooked to Sata channels so I thought that would speed things up somewhat. I am copying about 130 HD recordings so is this a reasonable time or is something amiss? Both drives are still spinning and the original 1TB had no issues going into this; just wanted more capacity. :D

    Thanks for your opinions.

    So, did it ever finish?

    No. I "pulled the plug" on it after 17 hours. I guess I either have too little patience ;) or WinMFS doesn't like the big copy jobs. I guess I'll spend the time to transfer off some shows and just use the truncated image to get my 2TB online.

    Wish I knew what the magic amount of shows (HD hours) WinMFS can handle in a reasonable amount of time.:confused:

    I could've swore it was all about a smaller window being hidden behind the larger on, and there WAS some way to force the small window to the foreground, even though it doesn't appear on the taskbar as a window...

    I don't remember the trick to do it, but when I did, and still used WinMFS, things happened at a good clip, just so long as none of the drives involved had back sectors or I/O issues...

    It should have finished in that length of time, so something must be amiss.

    It was a one-time upgrade that I did for someone else. I have not used a 4KB drive in TiVo HD myself, so I don't have a reference point for comparison.

    My original 250GB internal S3 drive had started having problems. I could hear it reseeking and then eventually crashing the TiVo. I ordered a ST3500312cs and copied the data from the old drive to my Linux box while I waited for delivery. I used the dd command and was happy that there were no disk errors reported.

    Having a backup, I put the drive back onto the TiVo to let it limp along till the new one arrived. The drive then ran without problems for 36 hours.

    Fearing that it still might fail I copied the drive image to the new drive and installed it. The S3 stuck on "powering up". The drive appeared to not be powered up. Do I need to configure the drive in some way? (I know I would only get 250GB by doing this, I have an external 1TB as well.)

    That external drive greatly complicates things.

    When you say you copied the data from the old internal to your Linux box, do you mean you used something like

    dd

    or

    ddrescue

    and created a file at least 250GB in size?

    It really would have been better if you'd stopped using the old internal right then to save whatever life it has left, but that's water under the bridge.

    Even if we're successful, I'm pretty sure that external means you'll only be able to use the first 250GB of that 500GB Seagate, and I may have to PM you how to do something risky with

    hdparm
