I posted an earlier thread about Sandisk memory cards not working from a firm called memory bits. Thinking they were seconds,or something like that.

I sent them back and took Sanu's advice and bought another 4.0gb SD card for my Nikon D40,from another company. This card was well wrapped in official Sandisk plastic wrapping. Guess what it wont work.

Took the card back to Jessops thinking the camera was false,as the 2.0Gb SD card works fine. Jessops tried the 4.0 Gb card in a D80 D70 and their D40 and the card would not work.

Checked out the Nikon website and it seems their is something called FAT32 and Fat16 in the Nikon cameras,which needs to be altered.

2.0 Gb cards work Ok wih Fat 16 but you need a firmware download in order to get FAT 32,which allows you to use the higher memory cards 4.0 Gb etc

Anyone else come acros this problem.....The funny thing is Jessops put the 4.0Gb SD card in a little Canon Ixus compact and it worked a treat.

That's perfectly normal and to be expected.

FAT16 is a very old File Allocation Table format that is no longer used in PC's (although all PC's are backwards compatible to it) and is a very inefficient way of storing multiple files - to put it simply with FAT 16 you use up more disc space than you would with FAT 32 using the same photos. Larger cards require the use of FAT32 to make full use of their capacity - to be honest I thought that all modern cameras all supported FAT32 anyway by default.

I would have thought the same as well,not so Nikon it seems. I have sent Nikon UK two emails,but no reply as yet.
