SOLUTION - Fixing "Disk Error" in hacked AK2025 players

I fixed mine with the chkflsh util which I think does the same thing, ie sets an active partition of the right size to match the available memory.

Check it with H2testw to make sure all the memory is usable.

The method discussed in this thread no longer works for most players. Here is a better solution for ak2025

Ok sorry misunderstood

The disk error seems to be the result of the partitions being in the wrong order, ie Partition 0: should be the active one with 2GB 16GB whatever and the smaller one of 17MB-50MB should be Partition 1: and not active as for as I can see. Not quite sure why the arrangement of 2 partitions, maybe have a play around with settings for a single partition and see what works best.

As far as i can tell, the partition that is active will be the one in use regardless of its position on the partition table. Correct me if i am wrong please.
In my experience disk error appears when the device has been loaded with more than its max capacity IE you put files in hacked memory that doesnt exist. On my players, the disk error doesn't go away even if you can successfully delete all the files on it. to go even further, the small partition (17-50mb) is not necissarry for the device to work but it puts the real memory either at the beginning or the end of the chip to avoid overflow errors. i think o.o

I had "Disk Error"with no files at all on it straight after format

I have a couple devices to play with now so I will try replicate the error and determine what causes it exactly.

Still not sure why 2 partitions, and you right, it can be made with only 1 partition using chkflsh util

Thanks for the solution
I used a similar method to fix up my bootleg machine from ebay and found your post just a little too late. Better late than never eh?

Don't know if this is helpful but I appear to have a new incarnation which was fixed up using this method (details below)

{
BKS2025029MV12 Board Number / Markings
Ding1027

SNW LCM LCD Display

K9GAG08U0M PCB0 Flash Chip

AK2025C Main Controller Chip

CL5767 FM Module

Reported it's Firmware as follows;

2008/09/30
9.5.54
2009/12/10
HST_SDKV91
}

The unit is unbranded but is remarkably similar (aside from the hacked OS) to the MN799 device offered by a popular (bonifide) supplier out of China that most of us will have used or heard of at some point.
