Sansa wont turn on/isnt reconized

Hello,

When the Sansa Express keeps freezing you can RESET the device using next step:
note:
The device can be either on or off, player NOT connected to the computer:
Press and hold the Volume Up (+) and Select buttons simultaneously for approximately 20 seconds.

When the "rebuilding database" message keeps coming back, the player will need an update.
Use the Sansa Firmware Updater (works on Windows only) or go for the matching download on the forum:
http://kb.sandisk.com/app/answers/detail/a_id/446/kw/database/p/555%2C662%2C687/r_id/101834
The Sansa Firmware Updater will contain the driver for the computer to perform a firmware update on your player [ METHOD 1 ].
When downloading the driver package manually, first put the driver "StMp3Rec.sys" in the correct folder on your computer. Next start the SansaExpressUpdater [ METHOD 2 ].
During this update, connection between player and the computer is based on MTP mode, Media Transfer Protocol: Drivers and software are needed to get access to the player.

The player could also be accessed in MSC mode, seeing the player as a removable disk. How to get connection in MSC mode, see next link:

If you downloaded the songs onto your player free from a mp3 website, there songs most likely were protected by a liscense which only allows you to listen to the for a certain of time (usually a month) as a trial so you will buy the songs to keep it as long as you like. If you do not wish to purchase the songs from that place you are getting them from, you can either go to another free website without a liscense on their songs and get them there or purchase them from another site you like.

Substitute REC for volume + in the following instructions:
These are the most common methods for recovering Sandisk's Sansa Mp3 Players. I have been almost universally successful in recovering Sansa players using one or a combination of these methods. These methods do not work if you are having synchronization or music format issues - they are for recovering a player that will not power up, freezes, flashes, is not recognized by the computer, and a host of other issues.

Reset the Sansa Player first. On most models, restart is done by holding the power button in for 15 seconds or longer. Check your specific manual to be sure. The manuals are available from the Sansa website if they have been misplaced.
Download the Sansa Recovery Tool from the Sansa website.
Format - Erases Everything: Connect your Sansa player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "Sansa 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.
Firmware Upgrade- Erases Everything: Get the latest firmware upgrade from Sansa - it updates the firmware and erases every song in the player all at once. Note: this method doesn't work if already have the latest firmware. Go to this website and click "Firmware Updater" to find out: http://www.sandisk.com/DriverDownload/driverList.asp
If these fail, then:
Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.
If you get the problem where MTP Device keeps popping up continuously, uninstall the “MTP Device” by going to Start à Control Panel àSystem à Hardware à Device Manager (you computer may vary slightly, depending on Windows Version).
You may have to restart your computer after each of these methods to get them to work properly. Disconnect your Sansa player BEFORE shutting down your computer.

If you simply just deleted the previous tracks that were on your mp3 player the computer might just reconize that they are still there and that it isnt necessary to put them on agian. if you try formatting your mp3 player it might help, or instead of sync your music to your mp3 player, there is always an alternative way, you could copy and paste them into the folders of your mp3 player.

hi, i was trying to delete some songs, which i did and now it won't come on. you think i made it stop working. i've been trying to delete songs for about and hour or two.it's doing nothing now. i'll wait about an hour before i try to turn it on again.

hold the volume button + - at the same time, and push the power switch up

ive had that problem b4 i dont no if uve already fixed it or not, but all you do is hold the power button fer 15 seconds and itll shut off

when ever i turn on the device it is saying refreash data and when am turning it off it will not turn off.

Hi there, one of the problems you have is that there is not much you can access from via your phone, so often the easiest (although not speediest) solution is to re-upload the songs. Have you tried adding another song, playing it, and seeing if that song will play successfully? If it does, then I would suggest deleting the other songs, and uploading them to your phone again. If this is not possible (because you downloaded them straight from mobile network), upload them to a PC and see if the songs will play - if they do, save them to PC, reformat your card (my computer -> right click on card name -> format) and then put them back on your phone. Unfortunately if they wont play on PC either, the chances are they have been corrupted and you may have to contact your download source for a refund or new copies. If after trying these options you are still stuck, try a) a mates memory card in your phone, and b) your memory card in a mates phone. If a works and b doesnt, contact your memory card supplier. If b works and a doesnt, then contact your phone manufacturer. Hope this helps and isnt too confusing - Chris.
