    Model 652;
    The HDD is constantly "thrashing" around. This has been going on for weeks now. I decided to do a power cycle which initially solved the problem, but only for a week. Now it's back to thrashing.
    I have a 2nd 652, but that is not doing this.
    This is setup for OTA & CATV w/ no CC if that matters. It also does not have any desktop functions (access) in use. It has a WD 1TB internal drive (WD10EVVS) with no external drive connected.

    This is not a noisy or bad hard drive. The thrashing is quite, it either has to be dead quiet in the room or I have to place my ear next to the deck to hear this. It sounds as it's doing a defrag process continuously or indexing (if that is what it is called). I used MFSLive boot CD to image the drive.

    Any ideas what is going on and why a power cycle temporally fixed the problem? :confused:

    How do you know the drive is not going bad, while working now? Have you pulled and tested? Do you have this exact same drive in the other Tivo?

    It's a brand new drive. It's a different drive than the other 652 which came with a installed 2 TB drive.
    If it was going bad, why would a power cycle stop it for a week or so? It's the actuator arm that is constantly active.

    To be clear, it isn't the noise level, the drive is quiet, it's the apparent constant activity. No, I haven't tested it yet, I just discovered the thrashing is back after a week of silence.

    One thing I should add, just before the first power cycle a week ago, I noticed sluggish performance while navigating the menus and guide. It apparently froze when I tried entering the system info screen. The background animation continued, but it didn't accept any commands. I power cycled just after that which cleared the two problems.

    Where did you get the image from?

    Could it possibly be that you put an old version of firmware on the drive and it is goong through a succession of upgrades?

    What number of software release are you on?

    From that DVR, it had the original drive in it.

    New drives go bad, happens all the time, drives can exhibit erratic behavior as they die. No idea why it would stop for a week, but if you are concerned I would pull and test. Up to you.

    Try clearing out the "Recently Deleted" folder and keeping it clean.

    your drive (WD10EZRX) appears to be an advanced format drive. Spec Sheet

    The constant thrashing may indicate cluster straddling caused by misaligned partitions. You may need to re-align the partitions on your drive:

    Is the "thrashing" youre talking about the seek noise a hard drive makes thats sounds like a crackling noise? Or are you talking about something different?

    I bought a used Humax DVD TiVo with a 1tig drive and it sounds like the arm is moving around most of the time. The TiVo also records shows in fine quality instead of basic and deletes shows even though there is a lot of room, so maybe I need to reload the software on it. I would have to learn how to do that though.
    Maybe I will just put another hard drive from a working same model TiVo and make sure it works OK then.

    I didn't mean to imply parted speaks Apple Partition Map, I don't know that. I was trying to suggest he examine the drive's partition map for mis-alignment as a potential cause for the drive's performance problems as detailed in the quoted article.

    As the Western Digital article explains, a little further down,
    Winmfs lets you look at the partition map of a TiVo drive and you can verify that the partitions are aligned properly.

    For example, this is an actual TiVo drive (not advanced format) that, I believe, would be mis-aligned if it were an advanced format drive:
    Code:
    Partition Maps

    I understand. It's just a PITA to pull this out and diagnose it by a stab in the dark. :(
    There aren't many recordings in there, the other deck has 3x as many (but a larger HDD).
    Correct as most of the new drives are now. (new and improved?). I'm reasonable sure I defeated this since I was aware of the situation.
    Yes, but a very muted "crackling" if you will. It's the actuator arm swinging back and forth as it does during a defrag operation or with a fragmented drive as it is reading the fragments.

    I have rechecked this sporadically and it isn't doing this 100% of the time. It does vary. It will settle down, then start uip again. Every time I also check the other deck (assuming it may be updates that are responsible. That one is quite.

    Let me go back and retrace my steps when I imaged this from the original drive. I did use the MFSLive boot CD method, not WinMFS which I will now use in the future since I have read further and my concern of doing this within Windows was not valid.

    I cleaned out the deleted folder, there were only 10 1 hour programs there. I deleted 6 more recordings that were duplicates from the other recorder, there are only five 1 hour programs that haven't been watch on the drive. BTW, I also have suggestions turned off if that matters.

    Much of the above suggestions makes sense, but I'm trying to understand why a power cycle temporary fixed this. :confused: How about any of those kickstart functions before I pull this off the shelve and take a closer look at the drive?

    Do you get the same temporary fix with a soft boot?

    Never tried that, but I will next time if nothing changes.

    Overall, it is no where near as bad as it was before the power cycle. I'll watch (listen) it closely the next day or so.
    If this was a PC, that unresponsiveness that I reported when I was navigating through the menus seems to tell me the O/S and/or processor had some type of lockup.

    The only thing I have is a SWAG - The disk is/was full and fragmented. When it first starts up, the beginning of the live buffers are in contiguous (or close) sectors. As more is recorded, the sectors get further apart, thus the thrashing. With an empty "Recently Deleted", thus actual free space to deal with, a KS 58 might accomplish something. However, having never run one myself, I am not in a position to recommend it.

    It being a Series 3, it's also possible that the power supply is causing problems. You might want to look at it and see if there are any bulging caps.

    Personal experience: I have a THD whose hard drive started failing after 3 years and was replaced with a 1TB (fortunately, it didn't completely fail and I was able to use WinMFS to copy and expand). I try keep the "Recently Deleted" folder cleaned up as I have noticed that it gets sluggish and/or I get flakey recordings otherwise. Been running like that for almost 2 years with no real problems.
