The differences between M4A and M4P.

The M4A format is the Audio-only MPEG-4 files. iTunes Plus tracks are encrypted and use .m4a accordingly. MPEG-4 audio files that include copyright protection, such as those sold through the iTunes Store, typically have an .M4P extension.

In January 2009, Apple announced that all music would be available in the iTunes Plus format, bringing an end to the sale of music with DRM on iTunes. It means that you are now available to transfer all your favourite music purchased from iTunes Store to your MP3 or MP4 players besides Apple’s Media players iPod and iPhone.

have bought one mp3/mp4 player from china. It had 2 GB memory and it had new version of firmware. Due to some error in mp3 player, I format it. Then when I checked memory space, I found that it has only 109 MB. I don’t know why mp3/mp4 player lost memory after format. Anyone else having the same problem. Please help me.
Thank you.

Re: mp3/mp4 player lost memory after format
Hey you are using fake mp3/mp4 player and that’s why you are getting such type of problem. You must check before buying whether it is working properly or not. Most of the people have such type of problem, who have take china made electronic device. If your mp3/mp4 player has warranty then you have toreplace it with new one to get rid out of this problem.

Re: mp3/mp4 player lost memory after format
Have you tried to format it using Command prompt. If not then use following steps to do this.
1.First connect your mp3/mp4 player to computer.
2.Now open Command prompt.
3.Now type “format _ ” (Instead of “_” use drive letter of your mp3/mp4 player )
That’s it.

Re: mp3/mp4 player lost memory after format
You have to use TestDisk utility to fix this problem. TestDisk is a powerful free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy.

Re: mp3/mp4 player lost memory after format
I able to fix this problem by using SD Formatter 2.0. I think you also use it to get rid out of this problem. This software formats all SD memory cards and SDHC memory cards using a formatting program that complies with official SD memory card requirements. SD formatting provides quick and easy access to your SD memory card. SD or SDHC memory card file systems formatted with generic operating system formatting software do not comply with official SD memory card requirements and optimum performance may not be experienced.

Re: mp3/mp4 player lost memory after format
I also had the same problem. Then as per your answer I used TestDisk utility to fix this problem and it really works for me. But one problem is there. I able to recover only 1gb from it. This means that now my mp3/mp4 player shows only 1gb free space instead of 2gb. Can anyone tell me how do I get back to 2gb. Is there any kind of software available.

Re: mp3/mp4 player lost memory after format
Hey I also have the same model and same problem. I also format my mp3 player and then it shows only 178mb free space. I tried various method to fix this problem, but nothing happened. Then after frustrating I replace my mp3/mp4 player with new one and I able to fix this problem. I think you also replace your mp3/mp4 player with new one to get rid out of this problem.
