MP4 player won't show real capacity

[Sunow]

Hi guys,

Received my fake MP4 player today, first thing I did was test it with H2testw to find out what its real capacity is, I found out that its real capacity was 1.8GB. So I tried out your guide in Windows 7, soon after I discovered that the mp3tools wasn't compatible with 7, so I booted into XP. So I tried it, and it spat out the error "Not supporting this type disk!" another thing to be noted is that it was showing 4073MB instead of ~1800MB. When I tried using the TestDisk method, it'd still give me the fake 7.68GB size, same with formatting within Windows XP and 7. So I tried splitting the mp4 player into two partitions using the mp3 player disk manager. Whilst it did do a low level format, when I put a song on, it gave me the error "Empty Disk!". To see what partition it was using I used the "memory info" option, where the MP3 player hung.

tl;dr:
Used H2testw to find out that it was 1.8GB
-MP3 Player Disk Manager spits out error "Not supporting this type disk"
-Mp3 player disk manager shows wrong(?) size
-TestDisk method doesn't work
-Split the MP4 player into two partitions
-Formatting in windows doesn't work

Thanks in advance, sorry for the wall of text, when asking for help I usually include as much information as possible.

**Fixed the empty disk error, turns out it was formatted wrong >.<
**The MP4 Player is one like this:

What version of MP3 Player Utilities are you using? I have the suspicion your player uses the newest AK20xx chipset which seems to be incompatible with the older versions.

Open it up and read the part# of the NAND flash to determine the true capacity. 1.8GB seems low for a 2GB player, unless the NAND flash is really bad (2GB should show around 1968M or 1.9GB.)

So far I've tried 4.18 and 3.68. The AK IC reads "AK1025" and the NAND is a Samsung 904 K9GAG08U0M PCB0. It doesn't say its real capacity on the NAND though, and when I Googled the part number I couldn't find a fact sheet >.<

Cheers for the reply.

In general the *G is the capacity designation. In this case AG = 16Gbit = 2GByte.

The recommended method is to repartition the drive and create a single partition of slightly less size than the real capacity (i.e. 1.8GB for your player.)
