Does JMFS copy everything, or just the blocks actually being used?
I've got the backup file uploaded to dropbox for you but need an email address to send you the link...and I can't send a PM til I have 10 posts...
The guy at DVRstore.com (DVR_Dude) mentioned that JMFS doesn't set things up quite right & leads to problems down the road, I don't know why. He suggested WinMFS.
Thank God. Playing he said/she said where everything's in writing just seemed silly
Woohoo - 10 posts! PM sent.
I'm planning to upgrade the original drive in my TiVo HD (TCD652160) with a 1 TB WD10EVVS, salvaged from a Sezmi DVR. Is there any special preparation I need to do on the new drive, like partitioning or formatting, before going through the MFS upgrade procedure or will MFS handle it all. I have no idea what file system is on the drive now, but I would guess it's some Linux variant like ext3.
You might want to run wdidle3 to see if Intellipark needs disabling.
MFS Live or WinMFS will overwrite everything on the drive, so as long as it doesn't have a Host Protected Area, nothing special need be done.
To check for HPA, boot from MFS Live cd
hdparm -N /dev/sda
where sda is the drive in question
It should come up with two long numbers and if they match, you're good to go.
So I ran MFScopy between the 1tb OEM drive & the new 2tb drive following the instructions in post 1. Do I need to mess with JFMS too?
I took the TCD658000 S3 HD XL image you "dropped" and restored it (with WinMFS) to a 1TB drive, which it completely filled.
Tried it in my TCD652160 S3 HD, and it boots (eventually) and I can run guided setup, but apparently the mismatch between the software being 658 and the machine (and its TiVo Service Number) being a 652 keeps it convinced it has an error 51.
Using that image puts only 4 MFS partitions on a 1TB drive, instead of the 6 you'd get from putting a 652 image on and expanding.
I used WinMFS to go from the 1TB to the 2TB, increasing the swap size to about 1GB, which leaves me with a big ol' Apple Free Partition, which would trip up jmfs, so I went ahead and let WinMFS expand.
It put 2 more MFS partitions on, filling the 2TB drive.
Tried that in my HD and got pretty much the same deal as with the 1TB, but in system info it appears it sees all 2TB of space.
Be a pioneer and go ahead and try it the way you've got it, with only the WinMFS expansion (at this point there's no room for jmfs to create that 16th partition anyway).
I suspect it might work just fine.
The HD XL and the HD both come with 2 MFS pairs on the stock drive, but since the XL's drive is bigger, they are bigger.
This means adding a third MFS pair (to an XL going from the stock 1TB to a 2TB) doesn't break the supposed "no partition bigger than 1.1TB" rule, the way it would with a regular HD.
I wonder if I can use jmfs to put a 2TB in a Series 2?
^^ Reading that is like reading a novel in Spanish, I get the gist of it but the nuances are lost on me
I plugged it back into the Tivo & works fine, shows 318 hours of HD space available. So I'm thinking I'm good now, no JMFS.
I'll report back here if something goes wrong, otherwise assume you can upgrade a S3 HD XL from 1tb to a 2tb drive usig only WinMFS & the stock instructions on page 1 of this thread.
Thanks all for the help, especially Unitron for talking slow enough for me to understand
How many SD hours does it show?
Something like 50 kajillion.
I don't remember but it looked right.
Has anyone ever tried loading the XL partition table then inserting the HD software over the top? Is that even possible? It seems like you could load the XL image and expand it and all then copy in the software from the HD drive. I know DD won't work because it will destroy the partition table but copying should work???
You can dd individual partitions as well as an entire drive (or parts thereof, if you know the right numbers for the starting and ending points).
When I can take my HD back offline I'm going to try that, but I'll use dd_rescue so I can see what's going on.
To nitpick, though, it wouldn't be loading the XL partition table, it would be restoring an XL image (which would include the partition table, of course) and then overwriting partitions 2-9 with the same from a non-XL HD drive. They should be the same size on both machines.
If nothing else, it'll help some with the question of what's in which partitions.
For instance if the THX video comes up, that'll mean it's in the MFS partitions and not the OS ones.
I have a TCD652160 (TivoHD) whose My Tivo Expander just died.
Rather than replace the expander, I'd rather just upgrade the main unit's drive.
I've replaced several Series 2 drives and think I won't have a problem following the OP's directions for replacing this Series 3 drive...but what drive should I get to replace it? The ones on the OP all appear discontinued.
I'd prefer one that's at least 1 TB and quiet. And cheap. Can anyone help?
This is a terrible time to be hard drive shopping, especially if you're somewhat financially constrained.
It may be a case not so much of what should you get as what can you find.
Have you taken the expander apart and tested the actual drive inside with the manufacturer's diagnostic software?
Are you sure it isn't just the eSATA cable gone bad, as has happened to so many people with external drives?
Currently, hard drive prices have sky rocketed due to Thailand flooding, so there is a shortage.
I just looked on amazon.com, the WD10EARS (1tb) is at $118, usually around $60. The WD20EARS (purchased in Oct. for $70), is at $144. (FYI.)
I'm thinking of upgrading my 540080 to a 1 Tb and was just wondering how many hours there would be.
You understood where I was going even though I did flub the technical details. If you get it to work on say a 1TB drive, can you upload a truncated copy so I can restore and expand it on to my 2TB?
