It's a battery from Mugen.

It's funny how things work.

I switched the battery for the original one, the one I discarded because it had some problem in the internal logic (sometimes it lasted for a day, sometimes for half an our).

Everything was exactly as you detailed, so the problem had to be with my Mugen's battery.

Then, I switched batteries again and now, the one from Mugen's behaves exactly as you described. The problem is gone.

I don't know what it was (you saw the video) but the good thing is now I know how to revert it if it happens again: I just have to reboot with the original battery.

Thanks.

Correct. I'm outgrowing the / partition I built on the flash [again]. I guess that's a good thing. So I am going to take the whole internal flash as my primary partition minus the vfat and swap partitions. I'll build a Mer partition on the external card, since it seems to be getting there.

Also you need to mkfs.ext3 on the new ext3 partition before restoring the backup.

1 more thing, I would reboot after using fdisk before doing anything else.
Thanks penguinbait. I just hate having my "brain prosthesis" offline while I do this in addition to the paranoia about screwing it up and having to start over again.

Hi PB and everyone!

Yesterday while running from my usual cloned partition on my external 8 GB SD card, I had a strange problem - could not run Terminal. It would launch and then close. I decided to reboot (tablet had been on for weeks), but when it shut down I saw a brief message that said something like "Memory corruption external SD" - it went by too fast to read.

When I power on, I get the boot menu (had used pbeasy last year), but if I select external it reports:

"Booting from mmc12 mmcblock0p2 ext3 "

but then I get jailbars and it reboots again to the menu. I can boot to internal flash (mtdblock4 jffs2 )

When I try to clone via pbeasy, it seems to only see a 2GB disk - I think it is the internal 2GB disk. I exited in in trembling fear.

I am able to connect via USB and see the 500 MB "fat" partition on the external card and copy the files.

Was wondering if I need to reformat the entire 8 GB external card. but I don't know how! <sob> Can't figure out how to run fsck - when I try fsck --help it just returns a version number. Sorry to be so helpless - I've been spending a lot of time with Windoze 7 lately and I think it hurt my brain.

Here's some info on the disk(s)

Rarrgh:~# df

All help greatly appreciated!

So if you boot to flash and as root run "fsck -y /dev/mmcblk0p2" what happens?

It almost sounds like the card actually died, although it shows up in your partitions list, so it must be functioning somewhat.

I have installed this successfully, my n810 can boot from internal flash or external MMC card. But, I don't know how to set the external MMC as the default boot device. I tried pb->bootmenu->Boot, but, the external MMC is not listed there. only 1 option:
/dev/mtdblock4 Size:256MB

What's the problem.

Thanks.

boot and open xterm and become root and run the following command:

chroot /mnt/initfs cal-tool –set-root-device ask:mmc12

Reference:
mmc2 is partition 2 on internal
mmc3 is partition 3 on internal
mmc12 is partition 2 on external
mmc13 is partition 3 on external

This sets the default, not sure why its not in the list?

Well, this is embarrassing.

The problem was my old, squinty eyes. I finally put on my reading glasses, fired up pbeasy, and lo and behold, there was a little, tiny, hard-to-see "+" symbol under the list of disks. Pressed it, and there was my external card. Partitioned and then Cloned without a hitch. Been running for a few days no problems. Probably had a flipped bit in some critical location. Well, after all, this is why I run from external SD in the first place!

<sigh>

People, I'm really sorry about this.

I'm braced for derision - please be merciful.

Steve

No issues here, best problems are the ones that sort themselves out...

Is backup to Fat32 supported with current PB tools?
