I just wanted to post a few notes regarding my experiences with the SanDisk Sansa E260R. Today, I attempted to play a SecurityNow! podcast and, low and behold, the Sansa rebooted for absolutely no reason. I thought nothing of it. The stoplight had turned green and I switched over to XM instead. At the next light , I looked down at the seat and the Sansa was stuck in some kind of loop. The SanDisk logo would pop up, then the Rhapsody logo, then it would restart. I held down the power button and it turned off after about a minute.
This afternoon, Recovery mode worked (Hold Switch On, REC + Power) and I copied the latest firmware to it. After unmounting the drive, I disconnected it from the USB cable. To my astonishment, the same results occurred: still rebooting.
It was time to search Google. Everything pointed to the firmware. Someone even suggested loading the firmware 3 times to see if it would take. It was almost time to give up when I found a small post suggesting dropping a blank file called sansa.fmt onto the recovery partition. After an unmount, the Sansa Recovery Mode formatted the drive and it booted normally, minus all the content, of course. At least I didn’t loose the device!
