FIX error code 21 or 13 withOut eeprom

[syikho]

just to throw my 2 cents in, and i cant garuntee it will work for everyone cuz in have 3 pc's and it only worked on one of them, but i have had this problem and fixed it in kind of the same way.  but instead of hitting pause break when the pc boots i wait for windows to load up, plug in the HDD, with the power still on to the xbox and all that, open up xplorer360 and, ofcourse i get that error code, but i can now access my xbox hdd and delete and add things as i see fit.  I have never been able to get the pause/break to work properly, and i also just plug my xbox as a slave, leaving the jumper in the factory position, but i have never had an issue with this method.  as i said though, i have 3 pc's and it only works on my newer compaq presario.

You are my hero ... you saved my Xbox .. I had erased By accident the xboxdash.xbe  on my console ... I had no idea what to do .. my xbox didn't work at all anymore I had the error 21 I went through many other websites looking for help and no one knew what to do .. they said I had to reformat my 250 gb  hdd and lose my 95 games ...  and then i came across your video on youtube ...  and it worked right away ... I got my Xbox back ... lol

for those of you for whome it doesn't work .. if your xplorer360 doesn't see the drive try this : unplug everything ... everything even the floppy drive.... I had the same problem at the beginning and then I noticed I had forgotten to unplug the floppy .. and it worked right away ... thanks again
