You might try RadioShack if you have one near you. I seem to recall that they advertised as being able to repair just about any electrical component. They are probably high priced, though.

Any TV repair shop or HAM radio shop/enthusiast can replace capacitors in this power supply.
This repair should be a no brainer, for a professional, especially with the "how to" instructions available.

That's why I like to do S3 HDs with a 1TB middleman.

Boot into MFS Live and then type

pdisk -l /dev/sda


That's a lowercase L, and that's assuming the 2TB TiVo to be drive is hooked up so that MFS Live sees it as sda.

Otherwise, it to sdb or sdc or whatever it needs to be.

Hit ENTER, and see if it reports an Apple Partition Map.


The type

poweroff

to get the computer to shut down properly so you don't accidentally do something to screw up the drive.

Once you give it a quasi-S4-ish or whatever bastardized partition map, stuff like MFS Live and WinMFS aren't going to know what to make of it.

But if it boots in the TiVo, that's the important part.


If you did your upgrade on a GigaByte brand motherboard, say so now, and we'll start trying to figure out how un-ruin things.

Is there anyone in NYC / Tri-state that can do repair/upgrades? I've got some items I can barter in exchange for labour. Pls pm.

A thousand times no.

They're a cell phone store that hasn't discontinued all the parts they once carried yet, but they're getting there, and not bothering to hire people who can tell a capacitor from a resistor.

That's good to know. I will cross them off my potentials list.

Thanks for the info... Nope it's an ASUS laptop. Everything went really smoothly, I'm just paranoid it was a little too smooth.

I'm sending a bunch of content to it today while I'm at work to see how it performs, I'll know when I get home...

So I have 14 partitions on the drive. The last one is media region 3 and yup it's 1.7T in size.

I'm concerned this won't work in the future... is there a way to change these sizes?

I'm not worried about losing the shows on the drive now, is there a tool that I can use to change the partition sizing?

So far so good ... no reboots.

But I'm still a bit concerned about the 1.1TB partition. If it's too big for the TiVo to handle because of the 1TB limit, would it have let me know by now? Or will I only know that something is wrong when it fills up 1TB and tries to write to the last 0.1TB?

There is another thread on upgrading the HD and plenty of anecdotal cases of users running a 1.7T partition, like the one I have, for several years without issues.

I put the tivo back together and am adopting a wait and see attitude..

I know it's possible to use a partition bigger than 1TB, even bigger than 1.5TB, but it has to be done in the right way for it to be properly usable by TiVo.

My problem is not a question of whether it's possible, it's that I don't know if I've done it correctly or not. All I know is that it seems to be working fine right now. I was hoping somebody would give me a clue about what would happen if I did it wrong -- would it immediately give obvious problems, or would it stay silent and run apparently OK until some day in the future it crashes when it attempts to write data to the sectors of the partition beyond 1TB?

Hmm, I think you might be the guinea pig for this one.

To speed up the process, turn on Suggestions and let the drive fill up. You'll eventually get your answer.

I think the upgrade to 11.0k* is supposed to be able to handle the bigger partitions, although the overall drive size limit is still 2TB

Which TiVo model did you start with and did you just copy the original drive and use jmfs?

I'm pretty sure the first 13 partitions are what was on the original and except for swap and var I don't know if you can change the size without the TiVo software complaining, because I'm not sure of where all it keeps track of that sort of thing.

You could use the always dangerous

hdparm

to put a Host Protected area on the 2TB, making it look like a 1TB, then use WinMFS to copy the original drive to that (and, if it were me, make the swap partiton about 1GB or 1000MB) and expand by adding partitions 14 and 15 (an MFS pair, which is how it does that), then remove the HPA, then use jmfs to add a 16th MFS Media partition of about 1TB in size.

Of course if you could obtain the temporary use of a 1TB drive as a middleman, you could eliminate having to use

hdparm

Open up the yellow pages, find a shop that repairs TVs and/or high-end audio equipment, call them, ask whoever answers to ask the techs if they do board level repair and can replace a low-ESR capacitor on a single layer board.

The shop with a tech that doesn't need that question translated or explained (other than telling them it's a TiVo switching power supply if they ask), and will do it for well under $50, parts included, is the one you want.

If you take the entire TiVo in and they have to remove the supply from the chassis it'll probably add to the labor cost, but then you can have them test the repair there in the store.

The more informal and "mom and pop" the shop is, the more likely they are to be flexible about fitting you in and pricing and such.

I'm thinking between $20 and $30 labor and $2 to $3 for the capacitor would be reasonable.

It's a 652160 and yup I used jmfs to go straight from the original drive to a wd20eurs.

It seems to be working fine, so until I have an issue, I'm going to leave it alone.

Thanks very much for the help!

Original S3 Upgraded from 1TB to 2TB

I'm puzzled.

If you started, back when, with the original 250GB drive, it had 13 partitions on it, 1. the partition map, 2, 3, and 4. the primary "boot trio", 5, 6, and 7. the alternate boot trio, 8. the swap partition, 9. var, and then 2 MFS pairs, 10 and 11, and 12 and 13.

Using MFS Live or WinMFS to copy it to the 1TB and expand would have resulted in a third MFS pair being added, 14 and 15, because that's how they expand, by adding MFS pairs.

If there was any space left at the end, it would have been called an Apple Free partition, and would have been partition 16.

It's been my experience that MFS Live will leave a little space going onto a 1tb drive, but WinMFS will use it all up when it creates partitions 14 and 15.

Copying that to a 2TB and telling it not to expand would either have left you with the original small partition 16 and the rest of the space ignored, or would have left you with an Apple Free partition of about 1TB in size.

If you hadn't already hit the 3 MFS pair limit per TiVo drive, then either program should be able to rewrite the partition map to convert what would be Apple Free partition 14 into MFS partitions 14 and 15.

But if you already expanded into the rest of that 1TB after copying the 250 to it, you should already have that 3rd and final MFS pair added.

Unless WinMFS can, when asked to expand via mfsadd, expand that 15th partition, leaving it starting at the same place but ending many GB further than before.

In which case, I don't think deleting the 16th Apple Free partition manually would be necessary.

I just replaced a WD20EADS in my S3 HD with a WD20EURS, so I have a 2TB to play with temporarily, so I'll try to do some experimenting.
Just followed the instructions using WinMFS and iBored to upgrade my already upgraded original S3 from its previous upgrade of 1TB to 2TB using a WD20EURS with Intellipark disabled. Sofar working just fine. MFS supersized failed when trying to apply it via the instructions but I think that is because my original 1TB upgrade had it supersized already. I thought I would post the partition maps during the process for information which may answer some of your questions.

Looking back on the partition map, wondering if I should of used dd to copy the drive and then used WinMFS to MFSAdd. I see my swap size decreased from 512 to 128. Using dd would of kept my swap partition and might not of created the apple_free extra partition. That way might be able to skip the iBored step.

WinMFS lets you specify the swap size, but since I've always used it to increase the size instead of leaving it the same, I didn't know it would revert to the original size for that model unless one specifically said different.

I'll have to watch out for that.

I have a TivoHD with a 1TB WD green drive that I "upgraded" to years ago and today I used WinMFS to marry a 1TB WD DVR External ESata drive (the supported one) to the internal 1TB drive. After booting the TivoHD after the marry operation it went to a blank screen after the "just a few more minutes" screen. It's been at the blank screen for over an hour now. I can hear the internal drive chattering away. Is this normal? Does it have to run fsuck and it's taking a while? The internal drive was probably close to full. Thanks.

larry

edit: Well, I let the TivoHD sit for over 4 hours with the blank screen and decided to power off the system to remove the external drive and see what happened. When the TivoHD booted it gave me the external drive was missing screen. I powered off and plugged the external drive back in and powered up. A few minutes later and all seems well, I have 287 hours of HD recording time and previous recordings are intact. Oils well that ends well, I guess.

Well tried a different tactic. I used a program in windows that does a RAW copy of the drive, so I copied the 1TB to a 2TB drive with this program HDD Raw Copy Tool from HDDGURU. The 2TB had the following partition table:

Partition Maps
#: type name length base ( size )
1 Apple_partition_map Apple 63@1 ( 31.5K)
2 Image Bootstrap 1 1@485366126 ( 512.0 )
3 Image Kernel 1 8192@485366127 ( 4.0M)
4 Ext2 Root 1 524288@485374319 ( 256.0M)
5 Image Bootstrap 2 1@485898607 ( 512.0 )

8 Swap Linux swap 1048576@486431088 ( 512.0M)
9 Ext2 /var 524288@487479664 ( 256.0M)
10 MFS MFS application region 589824@488003952 ( 288.0M)
11 MFS MFS media region 216747657@268618469 ( 103.4G)
12 MFS MFS application region 2 589824@488593776 ( 288.0M)
13 MFS MFS media region 2 268618405@64 ( 128.1G)
14 MFS MFS App by Winmfs 2048@489183600 ( 1.0M)
15 MFS MFS Media by Winmfs 1464320000@489185648 ( 698.2G)

Total SA SD Hours: 1040 Total DTV SD Hours: 908 1 % Free
Software: 11.0k-01-2-648 Tivo Model: TCD648250B

It had the exactly same parition map the original 1TB drive had. Then using WinMFS I performed MFSAdd on the drive and got this partition map:

Partition Maps

Notice the 15th partition was expanded but not as much as the original attempt that used WinMFS, iBored, WinMFS sequence. Not sure why. I did use a different 2TB drive but I would not expected it to expand it about 600GB less. That drive did not have any bad spots and was brand new out of the box. The MFS superheader has total_secs=3905170432 in the fully expanded drive and total_secs=2634017792 in the less expanded drive. It might be that the original attempt put the length and base of the partitions in order and not optimized. Not really sure if it makes a difference in the end. If I am interpreting it correctly, partitions go in order on the drive as 1,13,11,2,3,4,5,6,7,8,9,10,14,15. MFSSupersize did not work on the new drive either when doing it this way. Currently I am using WinMFS to copy the 1TB drive to another using no optimize partition layout and a 512mb swap partition. Then I am going to use HDD Raw Copy Tool to copy the new WinMFS copied 1TB drive to the 2TB Drive. That should put the partitions on the drive in numerical order with a 512mb swap on the 2TB drive. Then I will do MFSAdd to expand the drive and see if that will get the full expansion. Also I will retry with the drive that gave me full expansion to eliminate different drives as a factor. Will post results soon. BTW the HDD Raw Copy Tool copies the drive much faster than WinMFS.

Sounds like your Windows program does the same thing as

dd

or

dd_rescue

or

ddrescue

the first two of which are available on the MFS Live cd v1.4 and the last is, I believe, the program the jmfs cd uses for the copy portion of its copy and expand procedures.

It does a byte for byte copy.


When you ran mfsadd inside of WinMFS, did it ask you if you wanted to limit partition size to 1TB?

Because apparently that's what it did.

That's what I did ... suggestions are piling up!

I read about other people doing tedious things with iBored to get things working on their bigger drives, so I was concerned that my upgrade was too smooth and easy since I didn't anything more than a straightforward MFScopy and MFSadd.

Maybe so. I thought I told it not to do that but it was the wee hours in the morning and who knows what I clicked on. I'll try it again.

Like steve614 said, the white stuff is glue to hold stuff in place when they solder it.

If you take it to a shop, tell them there's a small dark screw that goes in from the outside into the top of the AC jack, and to use a low-ESR, 105 degree celsius/centigrade replacement cap.
Would a Rubycon 25YXF2200M16X25 capaciter be qualified? http://www.garrettelec.com/manu_specs/RUBYYXF.pdf

Are Western Digital "Red" Hard Drives suitable for use in a TiVo Series 3 (OLED)? I know they are NAS Rated for 24/7 operation. I'd like to use one, as they're less expensive then the recommended Western Digital AV-GP. Any assistance is appreciated. Unfortunately, my TiVo HDD (250GB factory original) is failing.

You are correct, in the wee hours of the morning I must of pressed 'yes' to the one terabyte question and not 'no'. Here is the new partition map:


Partition Maps
#: type name length base ( size )
1 Apple_partition_map Apple 63@1 ( 31.5K)
2 Image Bootstrap 1 1@485366126 ( 512.0 )
3 Image Kernel 1 8192@485366127 ( 4.0M)
4 Ext2 Root 1 524288@485374319 ( 256.0M)
5 Image Bootstrap 2 1@485898607 ( 512.0 )
6 Image Kernel 2 8192@485898608 ( 4.0M)
7 Ext2 Root 2 524288@485906800 ( 256.0M)
8 Swap Linux swap 1048576@486431088 ( 512.0M)
9 Ext2 /var 524288@487479664 ( 256.0M)
10 MFS MFS application region 589824@488003952 ( 288.0M)
11 MFS MFS media region 216747657@268618469 ( 103.4G)
12 MFS MFS application region 2 589824@488593776 ( 288.0M)
13 MFS MFS media region 2 268618405@64 ( 128.1G)
14 MFS MFS App by Winmfs 2048@489183600 ( 1.0M)
15 MFS MFS Expanded by Winmfs 3417825280@489185648 ( 1.6T)

Total SA SD Hours: 2082 Total DTV SD Hours: 1818 50 % Free
Software: 11.0k-01-2-648 Tivo Model: TCD648250B

So this is a simpler process. HDD Raw Copy Tool (or something similar) followed by using MFSAdd in WinMFS. Sofar it seems to be working. Will see as time goes on. Since this worked I scrapped the other experiment by copying to a 1TB inbetween to rearrange the partitions.

Looks like Amazon is asking as much or more for the 2TB Red as they are for the WD20EURS, which recently went back up from $100 to $120.

The WD20EURS uses an error handling method better suited to video recording than the methods employed by the type of drive on which you want to store spreadsheets and databases.

Use a computer drive in a computer and a DVR drive in a DVR.

I wouldn't be surprised if the Reds get hotter than the EURS, as well.
