iPod 5,5 (80Gb) doesn´t switch on anymore

<< < (13/13)

MIYU:
one other thing.

at one time when i connected it to my comp, my comp read it as a removable device but not as a n ipod. But every time it tried to get access to my ipod (removable device) my comp get a not responding and freezed for a awhile and i have to end task it.

yegods:
maybe you connected it while pressing the "menu" button?  that's the behavior i get when i do that.

I know this is getting toward heresay, but I also had this problem with my 80gb ipod. I just persisted with the hard reset sequence and it eventually worked. A couple of times I really thought I was in deep fecal matter.. but generally I could get out of it by enough persistance, the odd bit of extended charging and hard resetting. I think it all came down to Rockbox being the culprit. It would screw the battery measurement, run the battery until it was completely flat, and then crap out. Normally, under the Apple/iTunes OS, it'll restart because there is enough juice remaining to boot.. but after rockbox has sucked the battery dry due to dodgy power measurement, it wont start up. I don't know what it's like now, however.. there's been lots of work done on power libraries since I uninstalled.

I didn't uninstall Rockbox due to this matter, but due to the consistent never-ending Hard Disk corruption, cross linking and other false file dumps the Rockbox os would generate on my 80gb ipod. I ended up losing my entire ipod_control dir due to it becoming crosslinked, and (probably due to my own damn fault) chkdsk /f then wiped those crosslinked files upon repair. Generally I'd need to chkdsk every 2 weeks to clear off directory after directory of garbled nonsense, and massive 4gb "files".. maybe the FAT corruption was something to do with the way the new 80gb HDD was being read or written, I don't know. However, I'm not going back to Rockbox until its sorted because I don't want this to keep happening. Its sad, because Rockbox is such a great project and a better tool than itunes.

Totally, 100% wrong.
When doing my battery-bench measurements on the iPod video, I would repeatedly drain the iPod down to the point it stopped working, both in the original firmware as well as in Rockbox.
Apple firmware was just as guilty as Rockbox firmware in not leaving a "buffer" for the next reboot.

Wow this sounds like deja vu.
We have returned 2 80gb ipod videos to Costco that
have gone into zombe mode.  (one was returned twice, the other 3 times
so we have gone through 5 ipods!!!)  They would sometimes bring up
the apple logo and do a click, click on the hard disk.  They could
NOT be shut down after that.  (IE: screen dark, press the play button
to start, maybe get the apple logo, disk go click click, can't shutdown
and remove apple logo or stop disk from clicking until the battery
goes flat).

These units were NOT rockboxed, just running standard apple software.
Two of them went into zombe mode right after a resync with itunes.

So it seems there were some rotten apples out there.  I should have tried
charging them with my homebrew wall charger (just a 5v regulated power supply
connected to a usb cable with both data lines tied to ground).  Oh well,
we did get a complete refund from Costo after returning them for the 5th time!!!!
