Excellent. Many thanks!
x2, no problems here
This is my upgrade link:
I decided to give supersize another run (since I was going to screw the top box back, decided to give it another shot), so I turned it on... I did test it and it was fine, so I turned off the TV.
I came back in 2-3 hours the I got a black screen I was getting before, the weird thing is that the HD channels work on the local cable (no cable card), but the SD channels do not in either of the tuners. I'll let this go for another day and will note how many black screens I get on TV Turning on, and will revert back to supersize off to see if it goes away.
It could also be 9.1 related, or it could be a WD related issue... who knows.
I guess it's good I didn't supersize any of my boxes.
since my box is open and I have a usb->sata cable, I can test this a bit further, a friend of mine who is a Tivo Guru had a good thought, he basically wonders about the locality of the 30 min buffers when the supersize flag is on.
Again I get HD and not SD, next time it happens, as my friend pointed out, I'll test the HD for more than 30 minutes, to see if the buffer will run out or not.
what does the supersize do anyways ?
Also are HD and SD buffers shared ?
Of course I can't blame the supersize, because too many variables changed in the past couple of days, and one of them being 9.1.
Houman are you saying that when you undid supersize on your original drive the problems went away and when you redid supersize they returned?
Spike2k5 do you have 9.1 yet on your two systems?
No, my original drive was so messed up that I did another MFSBackup/Restore to fix it, so that does not count into testing.
Basically I tried the new restored tape w/o supersize with 9.1 and it did work for almost 24 hours (no BSOD).
Then I decided to supersize it (in the menu) -- I basically have the drive back on the Tivo, I just bring the whole unit to the PC and connect the sata -> usb cable (so I can do this often and for future) and brought it back to TV and tested and it was fine and the 131HD -> 144 HD in system screen, and I could record shows, etc.
Next time I turned on TV, I got the BSOD (pitch black screen), but menus would work... SD was out, HD would work, but I did not do the 30 minute play test.
Again I am not blaming SuperSize, it could be that if I had tested the un-supersized drive for 24+ hours it woulda done the same thing, I wish I had two Tivo's and I could do this test, that's why I asked about HD/SD shared buffers locality on disk, WD issues, 9.1, who knows...
Ok, just as an FYI, I have been BSOD free for the past 24+ hours, so that could have been a 9.1 fluke..., I'll let this run with supersize on, and if I have any problems in future, I'll post here.
Is anyone having success using an external eSATA on a TivoHD with 9.1 yet?
Well this rocks. I followed the instructions above and it was easy as could be. I put in a 500GB drive and after the tivo rebooted once or twice it came up ok. It might have been a bad idea to do this just after I had done the initial download while it was still indexing, but it appears to be ok.
I finally setup another 1 TB Hitachi Deskstar as a second internal drive in my TivoHD (my 1st 1 TB drive has already been filled up). The 2nd drive is a retail internal drive from Bestbuy. I changed the AAM setting from 254 (default) to 128, and paired it up with the 1st 1 TB (also a Deskstar) using spike's WinMFS tool. It shares power with the 1st drive using a 15 pin power extension Y-cable, and is internally connected to the 2nd SATA port (the one designed to work with eSATA) using the included internal SATA cable that came with the 2nd drive.
The recording capacity is now at 292 HD hours (with supersize on). So far it has worked without any problem for 5 hours. I am keeping my fingures crossed hoping it won't develop issues like it had a few weeks ago, when I tried hooking up an eSATA drive (a DB35/MX-1 combo), right after eSATA was enabled on the TivoHD by the 8.1.7c2 update.
Thanks again, spike!
It has worked flawlessly for a day now. No hint of any impending problem.
Nice! Any pictures of the layout?
I have not taken any picture yet. I'll remember to do that the next time I open the box.
I do have a picture now, but have not yet figured out how to load it.
How was the second drive mounted internally?
The 2nd drive is mounted onto a drive bracket from an S2, and the bracket rests on a couple of internal components against the middle section of the back panel of the case.
The internal temperature has stayed at the same 48 degree (C) as before the 2nd drive was installed.
My TivoHD was purchased in late July. So I may have been lucky to have gotten one with the 'old' power supply (see post below). I do not sense any spin up difficulties with the two Hitachi drives.
To those of you looking at adding a second drive inside the THD, you might want to check the power supply in the unit:
The "new" power supply is listed as 79W and 12V is listed as 1.2A.
The standard WD160GB 12V is listed as 410mA and the 1TB Hitachi is 850mA...**two Hitachi drives will need 1.7A to spin up.
Not sure what the available power is on the "old" supply as it was not printed on the PCB.
Im going to copy my THD 160 to a 500 tomorrow morning. Does the custom swap size option need to be messed with or just take the default? I copied my S3's original 250 onto the 500 just to get familiar with the process. Very Nice tool. Well done Spike.
Good point. This is probably a good use for a PowerTrip startup delay adapter. Once the two drives are running there should be no problem but at simultaneous startup you are seriously overloading the tiny power supply.
Edit: Might not work. Below, IBM = Hitachi. Not sure why brand of drive would make any difference, though.
"the PowerTrip has been tested with several brands of hard drives, and works with Maxtor, Western Digital, Quantum, Samsung and many others. The one known brand of drive that will NOT work with PowerTrip is IBM."The good news is that the TiVo is rarely power cycled so any stresses on the power supply are minimized. Mine has been on non-stop for almost a year (with UPS). As long as it physically starts up without blowing the power supply fuse you should be OK. I would definitely recommend a UPS, though.
That note may be related to IDE drives only when two drives share the same bus. Each SATA drive is on a separate channel.
I want upgrade my THD but am a little nervous since a user in one of the previous messages stated that TiVo knows when you change the machine which I can see how they would but is this of any concern? Mine is only a couple of weeks old and I have it exactly where I would like it and aside from a little trouble with digital audio (which I am sure is my receiver), the THD works great.
Also, I am assuming that when I use MFS to copy the tivo factory drive, that I would need a FAT32 partition? Mine are all NTFS at the moment.
