Hello, I am trying to install rockbox on my sansa e260 and I keep getting a message that I don'thave access to the disk.  What can be blocking this access ? Thank you

Seems you're hitting a similar issue as this one: https://forums.rockbox.org/index.php/topic,54173.0.html

Apparently something broke, and this appears to be a Windows-only issue. If you already have the bootloader installed you don't need to reinstall it. If you are installing for the first time you can simply grab the older Rockbox Utility 1.4.1 to install the bootloader.
