    If I order the WD10EARS is the manufacture date shown somewhere on the drive so I could return it if it is part of the older batch?

    I've always used the Linux command line versions of the MFS tools.

    Will I be able to create a backup image for an TCD652160 (HD TiVo)? It's the original drive, never booted.

    I'm trying one now, but my notes from last time say the backup always fails at 86% or so, which is where the file reaches 2GB.

    Command:

    backup -6so TCD652160.bak -f9999 /dev/sda


    CONFIRMED: Still doing this today. Using:
    MFSLive 1.4
    Kernel: 2.6.282Mfslive.org
    file size at error: 2147483647 (exactly one byte over 2G)

    Happens at 86%, at 3007 of 3463MB.

    I used WinMFS to make a backup of THD, tcd652, and the size was 440 megs, with only 1 show left in the recently deleted folder, original drive, and ver 11.0h. Plus, I burned the backup onto a CD, if anything happens to the drive, I still got a backup. Time it took to backup, for me that is, was just about 1 min.

    Do you have alot of recordings on that Tivo drive? Does 'Never booted' means you have a brand new box?

    I think you'd need a better excuse for returning it than "It's from an older batch" though. Most suppliers charge a restocking fee (around 15%) unless a drive is DOA.

    IIRC some folks have been finding fairly new drives at Best Buy and Fry's so it might be worth a look locally. You could probably open the box and read the date through the anti-static envelope.

    I removed it before powering it up the first time, used it to make my 1TB drive via backup ... | restore. It should be the pristine factory build on there.

    I tried again with -f 8888 and the initial MB count was the same 3463, so I aborted that one. WIthout the -f option entirely, it works fine and finishes at about 500M. I'm trying -f6888 now and the MB count looks low enough that it should be below that 2G mark.

    Is there some 2G cutoff for file sizes with this mfslive CD?

    No Fry's or BB locally so I think I will order from Amazon since their return policy is very liberal. $59.99 and free shipping since I have Prime.

    Don't know why people are looking at non AV hard drives in the first place, I'd think common sense would be to use a drive thats specifically made for DVR usage. http://www.wdc.com/en/products/index.asp?cat=7

    Probably…but you never know. Might be worth trying w/o it and see what happens. I know it's a big ask and another step if it doesn't work, but for purely selfish reasons I for one would like to know…plus the additional data point will be beneficial to those that follow. But if you don't want to help your fellow TCF members…that's okay…don't worry about us…we'll be fine. :( :D

    As explained earlier most folks are successfully using non-AV, low RPM hard drives simply because TiVo can't take advantage of a majority of the AV dedicated features the manufacturers build in…and AV drives cost more…about 20 to 30% more depending on the drive.

    After years of upgrading TiVo's with both types there's no empirical evidence one is better than the other, other than acoustics…the AV dedicated drives are delivered with the AAM set to 128. A few minutes work using a simple program will allow anyone to adjust the acoustics on a "stock" drive (from most manufacturers with the exception of Seagate) to the same.

    Ease of use? Agreed, pay some more, get an A/V dedicated drive and there's one less step in the upgrade process. :up:

    What do you mean TiVo can't take advantage of the AV features? What features, and why not?

    AV-specific features in the firmware allow such things as reads without error recovery; since a given read is known to be video data, it's more important to not hold up the read than it is to try to re-read the data over and over to get a good read (if it ever happens).

    TiVo simply does not need or utilize any of these extra features that exist in AV drive firmware.

    Though frankly it'd be nice if they could use it if it existed; it's certainly more user-friendly to see some garbled data now and then as a hard drive fails than it is to watch the TiVo lock up and reboot. :)

    That, of course is a shame. The problem is, of course, that the drive can indicate an error, but it is up to the host software (windows, Linux, TIVO, or IBM MVS) to decide what to do about the "error". In the case of Computer data like your checking account data, it better be correct. However, the problem with TIVO is that it is OK to just skip a bad sector while playing a show that was recorded. Heck, you would think it is the cable company anyway :D ! But the lockup is NOT OK. I am surprised that TiVo did not make its OS better than that! It is too bad that TIVO did not include software (a KS XX) that could be run to copy the "bad" show to another location without the bad sector and then have a hidden directory of bad sectors. That way, that sector(s) would never be used again. They could even have a KS to scan the whole drive and mark bad sectors. I bet a whole lot of TiVo's would be saved that way! How many times have we seen people come here to replace their HDD because all is OK except if they try to play a show they had recorded (or is that taped) :D everything would freeze!

    Actually if I'm reading what you're suggesting right (and it's been a long week, so some slack may be in order) Kickstart 57/MFS assert does in fact mark and isolate bad sectors along with its other tasks. It would be great if it handled the other things you suggest though.

    Enjoying the sun? :)

    Cross posting - posting the same questions on multiple threads is frowned upon by the TCF Moderators and is just bad form. I and others took the time to answer your posts, but in the future it's best to post once, wait for an answer. New folks get a pass. ;)

    Well, we just got back from Westfir/Oakridge and Silverton. I tell you, besides the darn rain it was scary in Oakridge before they shot that guy...near where we were staying in our RV, too! Police were all over!!

    P.S. There are so many levels that could be done in the TIVO OS.

    So I guess this was on the Portland news!

    Anyway, I guess it is time for my next 90 day free HBO/Cinemax. It is there now!
