Sandisk Sansa e200R

[Bagder]

Thanks!

Just for the record, is that e200r.tgz anything I care about?

And BTW, since you seem to have enough clues: can you do a "fdisk -l" on the device your sansa appears as and show it to us here? We're interested in seeing exactly how big the "disk" is reported to be...

[clutch]

I tried doing it in manufacturing mode and failled.  So I switched to the normal mode.  The .tgz file contains the three files that change every time I've updated the os.  I haven't done that for a while in case sansa / rhapsody is changing their drm along the way.  I seem to remember  a thread about that.

This doesn't look like a partition table
Probably you selected the wrong device.

I'm taking another nap.  Will check in later.

HTH,

Try again, with fdisk -l /dev/sdb (not /dev/sdb1 as you did previously)  

[clutch]

Sorry.

thanks!

Now, can anyone with a vanilla e250 player show us the exact same command line and its output?

[Bagder]

Hey, there's now a "Plan B" (http://daniel.haxx.se/blog/2007/09/03/mrhs-take-on-e200r/) suggested for those e200R owners who wants more adventure in their lives:

http://www.rockbox.org/twiki/bin/view/Main/SansaE200R#Plan_B

[krazykit]

This is on a Rockbox'd e250:

Code: [Select]

proto% /sbin/fdisk -l /dev/sdc

Disk /dev/sdc: 2010 MB, 2010120192 bytes
62 heads, 62 sectors/track, 1021 cylinders

Partition 2 has different physical/logical beginnings (non-Linux?):
     phys=(241, 212, 36) logical=(1010, 42, 13)
Partition 2 has different physical/logical endings:
     phys=(244, 97, 45) logical=(1021, 20, 52)
Partition 2 does not end on cylinder boundary.
If you need it on a player without Rockbox, I can remove Rockbox when I get back in a few hours.

To summarise :

Code: [Select]

Model  Heads   Sectors  Cylinders  Size
e250   62      62       1021       2010120192
e250r  213     35       512        1989148672

The difference being about 20MB - the size of the hidden partition on the non-R series...

Bagder, linuxstb, and GodEater all saw me on IRC, but we were able to convert the e200 to an  e200R (with the R bootloader) and, using e200tool, were able to convert it back.  In other words, the same thing that MrH did back in March, except this (for the most part) was for testing Plan B, which didn't seem to work.

[GodEater]

...and by "didn't work" chrisjs169 means :

The patched R bootloader froze his sansa on start up.

(assuming I interpreted his actions properly whilst reading them in IRC).

[chrisjs169]

Yes, using the patched bootloader found in the wiki (http://www.rockbox.org/twiki/bin/view/Main/SansaE200R#Plan_B) I tried placing the rockbox firmware file on to the Sansa.  The (patched) Rhapsody bootloader accepted the file without problems, but would not boot into it.

[Enterprise 1701]

Hello I'm new here.

I see that you have gotten the Bootloader to accept the file, but does not work with it. Could someone explain where that code came from that is listed above?

[GodEater]

Wait till we (chrisjs169) posts the how to.

[Enterprise 1701]

OK, Sorry for my impatience.

[GodEater]

On IRC, right now this second, we're trying to see if we can get the e200 (which we've turned into an R) booting Rockbox directly, without having to turn it back into a vanilla e200.
