History: My player defaultly not have a adressbook, after short time i found ready firmware with adressbook and stupidly flashed it to my player. after flashing my player reboots and i see on screen "Disk Error". access to all options in player has ben locked. i run "RDiskUpdate" tool but see "unknown flash type" message. Now i must format drive in my player. after formating "RDiskUpdate" flashed correctly old firmware, but i loss all data on drive.
Solution: before flashing make a dump of yours drive and partition data.
I found on the web small tool named "dd" http://uranus.it.swin.edu.au/~jn/linux/rawwrite/dd.htm (most linux users have dd in distribution).
DD helps make of a backup image of the USB drive to a harddisk.
Example for windows: (read complete USB drive to file)
dd if=\\.\X: of=c:\temp\usb1.img bs=1M
X is a letter of usb drive
now read only few megs (useful for restore old partition data after formating)
THIS WORKS! YOU MAY QUICK FORMAT DRIVE,FLASH CORRECT FIRMWARE AND RESTORE PARTITION INFO WITHOUT DATA LOSS
dd if=\\.\X: of=c:\temp\usb1.img bs=1M count=5
this read only first 5MB from drive
- Now for writting
dd if=c:\temp\usb1.img of=\\.\X: bs=1M count=5
for linux users:
- Code: Select all
