- Pin = 7
- Host = Only one : 3 V
- Secure = Support

Phone = Nokia 6630
- Dimension = RS-MMC
- Pin = 7
- Host = Dual : 1.8 V and 3 V
- Secure = Support

What is the difference between host 1.8 V and 3 V?
Host 1.8 V needs less power to operate, so ur Battery will not be drained quickly comapared to Host 3 V.

Note For Secure : Why NGAGE Game in Nokia Orginal MMC cannot be copied into other MMC - because this is Multimedia Card with type SecureMMC (have copyright protection).

PASSWORD RECOVERY

option 1: install and launch MMCPWD application. it will display some special characters including your password.

option 2: locate mmcstore file. install and launch System Explorer or FExplorer application. go to c:\system\ and open (using unicode/hex editor) the mmcstore file. it will display your password. NOTE: you can also copy the mmcstore file to any folder of your phone memory, rename it to mmcstore.txt and open it without using any unicode/hex editor).
via: Imserba Cell Phone Download & Community http://www.imserba.com/forum/showthread.php?p=171948

** if mmcstore is no longer available (let's say you already formatted your phone memory so mmcstore is deleted, or you bought a password-protected MMC, or whatever reason), proceed to formatting a password-protected MMC 'cause its hopeless to recover the password anymore.**


FORMATTING PASSWORD-PROTECTED OR CORRUPTED MMC

formatting a password-protected or corrupted MMC is different from formatting an ordinary working MMC. YOU CANNOT format such kind of MMC using any Nokia Series60 phone nor even the card reader.

To format those kinds of MMC successfully, use a digital camera, Nokia Communicator series phones (such as N9210i), palm devices, or any MMC supported devices other than S60 phones and card readers.

if all else fails, bring it to where you bought it and claim for a warranty (if not yet expired) or bring it to any certified MMC expert technician and see if he can do something about it.

help!!!
when i insert my mmc in my card reader it say that it is write protected. But i did not put any password on my mmc.i reformated my mmc 2x to make sure it was reformated but still it is said that it is write protected when i insert it in my card reader. the first one is from my friend's card reader and second one is on my phone. Also when i try to insert some of my friend's mmc in my card reader the same happened knowing that they don't have any password in there mmc. What should i do?? is the problem really in my mmc??

as far as i know, write protection is different with password protection. if the mmc is only write protected , u can still view/read the contents of the mmc. but when it is password protected, u can neither read nor write into it.

maybe there's something wrong w/ ur card reader or its setting. i'm not sure. try another card reader and see if the problem persists.

regards,

using nokia 6600
my 128 sd mem is damage
cant read/format form phone and card reader

is there any option
