Unfortunate - but surprising? Not really... it's eBay! ;)

I guess so. :(

@elfworks
I just want to make sure though, have you tested it inside the 770 yet? and if so, is the speed significantly slower? Cuz it just might behave differently in the 770 than when in the laptop. *crosses fingers*

Re: Boot from 2gb Card
 
So a quick question - to do the steps listed in the HowTo for booting off of the MMC, I'd like to use 2007HE, but all the steps either refer to the 770 or 800, but not 2007HE... Would it be advisable to first flash back to 2006, follow the steps, and before the actual copy flash back up to 2007? TIA (Woot Newbie :) )

cue79 - if you're running OS 2007HE, follow the N800 instructions.

that's what I thought. Any reason the unmount command wouldn't work as root? I keep getting command not found. tia

Taking a wild guess, you've probably fallen into the classic Linux newbie trap - there's only one "n" in the unmount command, it's spelled umount and not unmount. :D

I used the same software (ATTO ?) to test the MMC card that came with the N770, and the new one. The stock 64MB card was easily twice the speed. ( 2MB/Sec vs 4MB/sec.)

I also tested an A-Data 50X 2GB SD card with the same software, and got throughput up to 4MB/sec, so it's probably not the card reader/laptop.


As for the card that was shipped, ikt was a totally unbranded card - no label at all on the top, and just an indiscriminate part number on the bottom. ( 7169M102CS191MA TW - Turns up nada on Google.)

In the Device Manager, it shows up as Ricoh MMC Disk Device, Rev 1.00.

I'd attach screengrabs, but I don't have an image host yet.

For future reference, MMC Mobile (sometimes also called MMC Plus) is the best type of card to get for your 770s if you care about performance. MMC Mobile has 4 data pins compared to the single data pin in regular RS-MMC cards.

It also appears (on Expansys at least) to be twice the price of RS-MMC. :(

Too bad, I was thinking about upgrading my 770 one last time (which, ironically, is exactly what I said everytime before).
