error reading from disk

[krx]

i have been using Rockbox for long time
today i tried to install new Rockbox bootloader

and here what i've got:

Enter i to install the Rockbox bootloader, u to uninstall
 or c to cancel and do nothing (i/u/c) :u
[INFO] Reading firmware (5073408 bytes)
[INFO] Padding read from 0x004d6a00 to 0x004d6a00 bytes
 Error reading from disk: ╟ряЁюё эх с√ы т√яюыэхэ шч-чр ю°шсъш Ñ‚Ñ‚ÑŽÑ„Ñ€/т√тюфр эр єё
ЄЁющёЄтх.
[ERR]  Bootloader removal failed.
Press ENTER to exit ipodpatcher :

strange symbols after "Error reading from disk:" means something like "the request hasn't been completed because of the I/O error in the device"

then i restored my ipod with original iPod Updater and ran ipodpatcher again,  and press "i'

Enter i to install the Rockbox bootloader, u to uninstall
 or c to cancel and do nothing (i/u/c) :i

Ok...if run into I/O errors on other players before. Make sure that you are logged in as a computer administrator. If that does not work make sure you have the latest updates for your computer because it might be a driver issue

[krx]

what driver? usb-controller?

i've connected player to motherboard's USB > everything is ok
thx
