How 2 check memory space on mp3 it saids 94% does it mean left or used

available space does not mean that there will be much space. when putting sd card in any tablet, tablet reserve some memory to process. please explain how much memory left. also check any hidden files and icons from sd card.

hi,

Check your memory card properties,see if your memory card is really 4 gig.Also check the free space and the used space capacity..Try to insert your memory card to other device to make sure your memory card is working..Hope this may help you.

Invalid MBR = Invalid Master Boot Record.
This means that your player Flash Memory drive is corrupted and unfortunately may need to be reformatted if you cannot repair it using some Disk drive or Flash drive utility.
You can try to use 'Properties -> Tools -> Error Checking -> Check now' to fix the issue.
If you have a backup of the music on your player, I would simply use Windows Explorer and FORMAT it using FAT32.
Hope it helps.

This means the memory can't take anymore information in such as contacts, inbox messages. If you see that this problem is caused only in Inbox of the Mobile ( As you said it is doing it during sending Message, and sending message requires Inbox space ), then the problem is in the memory card. Also go into the File manager ( Menu > Tools > File Manager ) and from there to Phone Memory options and to Memory Details. There must be a very little left space. Check it and reply me.
Thank you Sir, Have a nice day.

ok when your in the mp3s folder click on tools then folder options and then the view tab look down near the bottem of whats displayed and check the box show hidden files and folders and see if there are any files being hidden on the device if not then id say get the firmware and device manager for it and reformat it just keep the firmware and device manager handy so you can restore it if anything goes wrong after the format

That's because no offence but it has rubbish memory. 25mb is nothing these days. Most songs are 9-15mb themselves these days, and so no wonder you have no space left.

You are attempting to add music to the disk function on your device make sure it is on the mtp function so that all of your memory is avalable. this is done when you dturn it on and then hook up to your computer. You'll figure it out I did the same thing a couple times - Good Luck

make sure this size is as said it could contain somethingg harmful and have a larger amount of MB's.

Try to scan the anti virus, maybe there's some virus that can corrupt when you are adding some songs. If you check it and was not found yet, there's a possibility that your memory have a problem.

Try formatting it....when you right click on the sansa image on ur comp...click format
