Refurbished Sansa 1gb Mp3 player loses recently downloaded songs

Check if the size of the disk is actually what they say it is because I have seen where 1gb was written on an mp3 player whereas it was stretched, e.g, 128mb might be stretched to 1gb, so whenever you put songs that exceeds 128mb the other ones will not play at all. It has happened to me several times.

hook it up to your computer and allow windows media player to sync your mp3 player to the computer.

These re the songs that came with the player even if it is brand new, and plus since these artists don't want these to be copied they use a special method to hide them form any OS, hope i helped....

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/Retail/DriverDownloads.aspx

the best way to solve the problem is to return it to the store! let the sudisk solve the problem and only after that to sale them

Make sure you're not using the media with another program while you attempt to copy/sync it to your device.

Pretty late response, but meh.
