Nokia6600 - Get more space for your MMC

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. I have a 256MB MMC and it is nearly full with (small) program files. After doing this, I gain an "extra" 35MB. ===Edited=== Note that you will gain extra free space and not total space. 256MB MMC will give total of 256MB no matter what block size you use. File Size + Wastage = Total MMC Space (constant) You reduce wastage then you increase the file space. __________________ yes, but if you use bigger files more data is needed for saving and reading/writing goes slower... a good tip is to defragment your mmc to make it faster __________________ Quote: Originally posted by kristof.vanriet yes, but if you use bigger files more data is needed for saving and reading/writing goes slower... a good tip is to defragment your mmc to make it faster If you use your MMC just store MP3 (large files), then it may not make much of a difference. Just a note that if you do the step in my previous post, implicitly you have done a defragmentation also. __________________ Yeah, right... Just make sure your phone will recognise that reformatted card in the first place... Then you'd need a cardreader that supports format options, some of them do not even format MMC, just recreate empty FAT __________________ Quote: Originally posted by D-Off Yeah, right...

Then you can use Windows to format it. If your card reader cannot be recognised as a removable/usb drive then you can forget about doing this. For myself, I have 256MB MMC and I reformated using 4K block (this is smallest possible). Copied back files and I got extra 33Mb of free space. No kidding. And there is no problem with the phone recognising the MMC. I'm using a 6600. Mavi forum
