What size is your hard drive and what size is your swap partition?
Hardly anybody knows the size of their swap file.
FYI, if you are thinking that a larger swap file will fix the problem, I don't think it will. Here is what trackie999 had to say in post #271:
"I did a test over the last 5 days experimenting with a 2.5GB swap partition to see if that allows GC to run any faster. Well, I am sorry to say it does not make a difference...
There were a total of 19 dbgc attempts over the last 5 days and all of them ended with eMfsTooFast exit code. Majority of the attempts aborted within 30 minutes with a few almost making it to an hour and 1 or 2 running for a couple hours.
There is one very interesting thing I noticed. dbgc always gives up seconds after the hour or half hour. For example: "
Not sure what size original drive--either 500GB or 1 TB with a 1TB extender. No idea on swap partition.
I know the size of mine 'cause I'm driving myself nuts trying to figure out how to increase it and use jmfs.
Tivo's default swap size is 128 Mbyte. WinMFS also defaults to 128 Mbytes, although it gives you the option to change it...
I still have 1 Tivo running with a 2.5Gbyte swap and it makes absolutely no difference. I checked memory usage many-many times and I have never seen more than 10 Mbytes of cached data in swap.
Default swap partition size depends on the model. The HD is, indeed, 128MB.
As I understand it, TiVo uses the swap partition if it gets in trouble and you have to run one of the Kickstarts to straighten things out, and if you've got a larger than stock drive, it might need more swap than stock.
You can copy the stock drive to a larger one with either WinMFS or the MFS Live cd and both offer an option to choose a different swap partition size.
Problem is, even if you also expand, adding 2 more MFS partitions, there always seems to be some left over space at the end of the drive, and that gets written to the Apple Partition Map as an Apple Free partition.
jmfs thinks that is a real partition and adds the one partition it adds after it, which apparently makes the TiVo unable to see it.
The only solution I've been able to think of so far is to get another 160GB drive with a few more LBA than the stock WD drive (maybe a Maxtor would work, they've got an 80GB that's a little bit bigger than the WD 80's), and copy with as big a swap as it'll let you so as to fill the drive and eliminate the Apple Free partition, and then use jmfs to copy that drive to a 1 or 2TB and expand.
I tried copying the original 160GB WD to a 200GB Maxtor I have on hand, setting the swap to about 40GB, just to see if I could get rid of the Apple Free, and I tried doing it with a 1GB swap and expanding, but even adjusting the swap size 1MB at a time, I could never find the magic combination that gave me a drive without an Apple Free partition on the end.
It seems that the block Internet access solution doesn't work for me anymore.
Internet access is shut down for 48 hours at a stretch, and GC will not complete.
So I powered down the TA (via its power button) and will turn it back on once I verify that GC has updated.
Interestingly enough, I have two identical TivoHDs. One has this problem, one does not. Odd.
Are they identical identical? Same brand, model, size hard drive running same version of firmware? Same size partitions on both?
Is the heat sink on the power supply the same color on both? (okay, that shouldn't affect the GC problem, I'm just wondering how many different versions of the HD power supply there are).
AND THE FUN CONTINUES!
So I did the reboot, connected back to the internet, and initiated a connection. After 9+ hours it's still stuck on "Loading (Setting Clock)" and the System Information page looks scary, with most info missing and my Account Type listed as C:120311 (which I assume means a month to month account? I've always had lifetime). So I'm rebooting again, have disconnected the TA, and will initiate another connection.
Yes, yes, yes, yes, yes, and I don't know. Heatsink color? Really? No f-ing clue. Nothing struck me as out of the ordinary 18 months ago when I performed the upgrade. And I'm not about to crack open the boxes to look now!
The power button on the TA did its job. After about two and a half hours of the TA being off (Internet was available that whole time), GC updated. No more warning messages about guide data running out!
Well then, if the drives are the same I guess we can officially list the cause of the problem as gremlins.
This morning I checked and the connection had been successful, the GC date was current, and everything seemed back to normal in my Settings (showing my Lifetime). Though it still only shows guide data for a week out instead of two. But at this point, I'll take it. Now to get the TA on a timer - does it need to be every day, or could it be every few days (requiring a digital timer that you can set for certain days)?
Congrats on your success!
Maybe this is just TiVo good luck day in the ol' river city. Overnight I stumbled into a solution for using all of a 2TB drive in the S3 HD I just acquired and repaired the power supply on.
The timer can be on any schedule you want. Every few days will work just fine. Once a week will work just fine. The only downside to infrequent program updates is that you will miss any last minute program changes, but I don't think they happen very often anyway.
Are you looking at Guide Cache instead of "Program Information to" again?? Overnight I would expect 2 weeks of program information. Guide cache is always just 1 week.
Please tell us more about the 2TB drive solution.
10 bucks at Ace Hardware brand. Turns off and on daily.
A digital would be good, some may say better. But I wouldn't spend the extra bucks at this point.
Mine is set to turn off power at 0100 and back on at 0400, daily.
So far GC updates every other day in the 0300 hour range (today's said 0311.)
NONE of the dates on any of the screens were anything past 11/15 or so...I SWEAR! Because I looked at everything over and over to make sure I was seeing correctly. But...I just looked again and the Program information date says 11/22 so maybe the guide data just wasn't fully done updating yet when I checked first thing this morning?!
I am setting this up immediately! Thanks!
I hope you haven't already seen my epic saga
and are just being sarcastic.
Well, the HD updated only once by itself. Unplugged USB forced connection and GC happened in a couple of hours. After that there was again one GC update by itself. Got down to only 8 days left in the guide with no GC, so I put the USB cable back to the original configuration and before plugging back into the TA forced another service connection. Today I had to do it again but GC shows completed at same time as service connection succeeded. Only took about 15 minutes total. I have run USB extender cable around to front and plan to continue that way for a while.
BTW both TA's show the 1501 firmware update.
The Elite continues to do both the Service Connection and GC daily. No problem with it so far. I guess the answer to the question posed by this thread is that Tivo will fix the problem on the 12th (of Never!)
