How do I recover a recording deleted accidentally from Sansa e250

It is possible to recover your lost recordings.

First things first: DO NOT take any more recordings with the MP3 that you want to recover records from in case you may quite possibly ruin your chances of recovery.

Then Connect the MP3 to your computer as it should appear as a "Removable Drive" or put the card in a card reader attached to your PC.

Next, if you are comfortable with using a PC then you can download a data recovery utility that will recover your recordings with Wondershare Recovery Software from the following link:

Video Audio Photo Recovery (if you are running Windows OS)
Mac Data Recovery (from MacUpdate site)

Do NOT try & write anything back to your MP3 until you can recover your recordings safely!

You may try asoftech data recovery which helped me before. You can download trial for free

Please be noted that your Sansa e250 memory should show as a drive letter in your explorer, if not, you need to take out your memory card and connect using a card reader, or plug-in to card reader slot if there's any on your computer.

Hello, cristianratz! Don't worry. I recommend you to use this photo recovery software (also recover audio and video files); it can help you recover your lost files from your Mp3 player:

For Windows Users -----> Photo Recovery Software

For Mac OS X Users -----> Mac Photo Recovery Software

Kind Suggestion: Before your files are retrieved, do not save more files to the device (or memory card) in case the original files (your multimedia files) are overwritten.
Best wishes!
