I don't think Steve was saying it only works with 4GB, I think he was saying that's the only one he'd tried. -- <http://ale.cx/> (AIM:troffasky) (UnSoEsNpEaTm(a)ale.cx) 13:15:50 up 40 days, 17:11, 5 users, load average: 0.24, 0.07, 0.02 DIMENSION-CONTROLLING FORT DOH HAS NOW BEEN DEMOLISHED, AND TIME STARTED FLOWING REVERSELY

I think you can make an SD card any size up to 4GB (and I expect the original SD spec allowed for this) but it's now been agreed that the change from SD to SDHC happens after 2GB to match with the point at which the normal format used changes from FAT16 to FAT32. That way there should be less confusion caused by SD compatible devices that can't understand FAT32 vs SD devices that can understand FAT32. I believe it is also possible to have a FAT16 drive of over 2GB in size but Microsoft has now designated that as non-standard and the normal formatting utilities included in Windows won't format anything over 2GB as FAT16. I'd be interested to know if the few 4GB SD cards that were made before all this was agreed were supplied formatted as FAT16 or as FAT32. I've a feeling FAT16 can only be pushed to just under 4GB but maybe I'm muddling it up with something else. -- Brian Gregory. (In the UK) ng(a)bgdsv.co.uk To email me remove the letter vee. |
