Archived:Retrieving memory card unique ID using Symbian C++

Comments

Whilst article claims this supported on S60 1st + 2nd editions, the f32file.h hdr for 7.0s, 8.0a, 8.1a SDKs does not actually contain the method. Looks like its a Symbian OS 9 (S60 3rd edition) only feature.

Thank you for your feedback. The article has been updated.

Description

The unique serial number from the MMC card identification register (CID) can be retrieved with the following function (if supported by the media):

 TInt RFs::GetMediaSerialNumber( TMediaSerialNumber &aSerialNum, TInt aDrive );

Solution

RFs::GetMediaSerialNumber() returns 16 bytes (128 bits) which are a copy of the card's CID register, defined as follows:

Description	Field	Width	CID bits
Manufacturer ID	MID	8	[127:120]
OEM/Application ID	OID	16	[119:104]
Product name	PNM	40	[103:64]
Product revision	PRV	8	[63:56]
Product serial number	PSN	32	[55:24]
Reserved	-	4	[23:20]
Manufacturing date	MDT	12	[19:8]
CRC7 checksum	CRC	7	[7:1]
Not used, always 1	-	1	[0:0]
