How to make MMC have more space

Your files in MMC is stored in multiple (disk) blocks.
So if you format using 16K block, the space used will be 16K eventhough your file is just 1K.

If you buy MMC, it is usually preformatted with 16K block. Therefore a lot of space is wasted as most installed program files are usually less than 2K.

You will need a card reader to do this:-

1. Connect card reader and copy all your files in the MMC to computer disk.
(Make sure you set the show all/hidden/os files to "on")
2. Do a format of the MMC using command line "format" and use the /A=size option.
Alternative, you can use the Disk Management in Adminstrative Tools to format.

Make sure you select FAT16. For 256MB MMC, smallest block you can use is 4K, 128MB is 2K, 64Mb is 1K and 32MB is 512B.

(Note: You cannot use the phone "format MMC" to do this as the format just clear the allocation table and does not change the block size)

3. Copy back all files to MMC.

Now you will find that you will have more space.
For my 256Mb MMC which is nearly full, I got extra 35Mb after doing this.
And there is no stability or problem.

====Edited==
Note that no matter what block size you select, you total MMC space will remain (i.e. if you have a 256Mb, you still get 256MB in total).

Total File Size + Wastage = MMC space (constant).

If you reduce wastage, then you got more file size. As simple as that.

Here is a quick one.

Your MMC (like a disk) is organised into contigous blocks. The block is the smallest ADDRESSABLE unit on the MMC.

Assuming the MMC "block" size is 16K, and you are store a file of size 20K into MMC, then you need 2 blocks to store the file. The first 16K of file goes into 1st block and remaining 4K into the 2nd block.

Therefore 2 blocks (i.e. 32K) of MMC space is used to store a 20K file. Therefore wasted space is 16-4 = 12K.

So if you reduce the block size, you can reduce wastage. This is especially so if you have many small files (which is the case when you install program files).

mib1800,Doesn't smaller blocks size mean slower read/write speed?

I have done it for mine and I didnt notice any reduction in speed.

In fact, I would think it will increase speed if the file is small (i.e. file fit into 1 block) as MMC reader only transfer a smaller size data.

Or you could use a program I wrote called 'MMC Medic' which will automatically format the MMC to the smallest block cluster size.

In w2k it is:

Start > Settings > Control Panel > Administrative Tools > Computer Management


Open Computer Management and there under 'Storage' you will find 'Disk Management'.

No idea about XP (location should be similar).
