Dead Sansa Fuze?

I have a 3 yearold 8g fuze that suffered the same symptoms before it died. It only shows up as a 4.3 mb drive that’s unformatable.  According to the guys at rockbox, the fuze is in pre-boot mode. The nand memory has become corrupted and needs to be reflashed. A step by step recovery method is here in the rockbox forum and more here: http://www.rockbox.org/wiki/SansaAMSUnbrick  I have a second fuze or I would be saying if this works or not. It is alot of work if you don’t already have VMware, Cygwin or Ubuntu running under windows.
