Couple of ideas.
use XP, make sure you have latest Windows Media player 11. Get the Sansa Updater program here http://www.sansacommunity.com/forum/thread/11116/Sansa-Firmware-Updater/?high...

Install it and make sure it is running, be connected t the internet and then do the above trick.

Also look and see if it creates a new drive for the device in windows explorer.

I hope you got it charged. If so....

First step: Open the back--four little screws, be careful not to lose them--and take out the battery for half a minute and put it back in. It's a different reset than the power button.

Do you know if you have a v1 Sansa (more than a year old) or a v2 (released about a year ago, but both v1s and v2s were on sale all year)? Look on the back: E200 is probably a v1, E200v2 is probably a v2--but only probably.

There are different steps if the battery trick doesn't work, so don't give up.

Did you look in the Rock box forums to see if they had any hints?

I have the same problem excatly. and i am unable to solve it. Help me out guys.

I bricked my Sansa e250 a few days ago. Only the blue scroll wheel would come on and I couldn't even get the screen to light up. It was a goner. I had very stupidly tried to format the 16mb drive. Apparently, that's the one thing we should never do. But, after a couple of days of trying everything under the sun, I finally did get it back into working order. I found the following post in the sandisk.com forums a life saver. I had to find the required downloads on my own because the link to the recover.rar file was no longer valid. But, it actually wasn't difficult to just google the file names as they appeared in the directions.

I copied and pasted the post for convenience. But, here is the original post (message #8): http://forums.sandisk.com/sansa/board/message?board.id=e200&thread.id=4865&vi...

Needed files:
e200tool for windows: http://www.rockbox.org/wiki/pub/Main/UsefulSansae200Tools/e200tool.zip
- there's also a Linux version, if the Windows version doesn't work for you

libusb-win32-device-bin-20060827: http://sourceforge.net/projects/libusb-win32/files/

e200 bootloader and firmware: http://chrisjs.com/howto-e200r-to-e200/
- look under #5
_______________________________________

1. Download recover.rar from here (SKIP THIS)
2. unpack the libusb-win32-device-bin-20060827.tar.gz to (example) c:\libusb
3 find e200tool.zip and unpack it to (example) c:\e200tool

lots of archives isnt it )))

DRIVER:
1. connect using manufacturing mode (hold button on + center button while connecting)
2. In device manager find unknown device under USB and update the driver. Select driver manually. Navigate to 0781-0720.inf (came with the archive) (c:\e200tool)
3. When windows promt you to install "libusb0.sys" direct it to с:\libusb\libusb-win32-device-bin-20060827\bin\
4. Start-> run -> cmd
5 type:
cd\
cd e200tool
e200tool recover BL_SD_boardSupportSD.rom
6. windows will find another usb device so instead of "0781-0720.inf" choose 0666-E200.inf
7 disconnect player and restart it

STEP 3 (recover bootloader)
1. connect player in manufacruring mode
2. Start-> run -> cmd
3 type:
cd\
cd e200tool
e200tool recover BL_SD_boardSupportSD.rom
but before you hit enter press and hold record button (very important)

Step 4 (firmware update)
1. connect player in recovery mode (RECOVERY MODE!!!! with record button)
2. copy PP5022.mi4 to 16 mb partition
3 restart player


I had to give this a try several times, before I got everything straight.

well I have a sansa e250 v2 with firmware v03.01.11a. Now I am able to turn it on, all the menus are usable,the screen is bright and clear, the radio works and all recording functions work. Only thing it isn't recognized by Media Player 11, it doesn't appear in device manager or in My computer. I have tried using the following "recovery" mode procedures: all of them have the hold button "on" or in the so called locked position. And all the procedures have the unit 'off'. the second step is either holding the 'rec' or the rewind or the center button in while connecting the usb cable to the player.

I have rotated cables, ports in the rear of the PC, and even removed the battery for 30 secs or so. I take care to 'shutdown' the unit each time a test is performed.

I have tried these procedures in Win XP SP3 and in Knoppix 6.2 using a live disc. Neither platform recognizes the unit in any discernible way.

So in this case, with the unit's menus fully operable - what is the issue? BTW this unit was bought as a Rhasopdy bound unit for the purposes of downloading songs and worked fine for about 2 years and then suddenly all the songs were gone and the present 'brick' now ensues. also no attempt has been made to load any other software etc.

Kingside

i can't install the driver. can anybody help me? i have a sansda e260 4gb
