This is a case of when Computer Format does not equal Camera Format.......
I will not get technical..... If you were using a computer to format your
cards, this is the info you need......
ALL SD Cards (up to 2GB) cards are setup with FAT32 ( oldest standard)
ALL SDHC ( up to 32GB) cards are setup with FAT32. ...... from the factory. (
ALL SDXC ( 64GB to 2TB) are setup with EXFAT from the factory. (newer standard)
Do not use other protocols. Your camera can not read them.
Your camera is setup to read or write to either card (SDHC or SDXC)... or
not...... Depends what software the maker put in the camera.
You will get little help from the camera makers as to which format the camera
can read..... sometimes, they put in max capacities of cards that they would
allow you to use...... so rules are not rules.
Assuming you have a newer camera, and want to use a 128GB (SDXC) card, you are
probably OK.Assuming you have an older camera and want to use a 128GB card, try
it out and see what you get for results.
In earlier days, this was terribly spotty, and it was card brand oriented. A
In camera formatting does 2 things.... it does a quick erase format of your
card and it sets up a few directories where the images and some other info are
placed. The images folder is pretty standard. The other folders are not.
They are brand specific. But you do not have to pay attention to them.
1) Do all digital cameras now work exclusively with the MS-DOS (FAT 32)
format, or would re-formating into another protocol such as Ex-FAT or
one of the Mac's (Mac OS Extended, Journaled or Mac OS Extended, Case-
Sensitive, Journaled) work or render the card useless at least for
2) If another format would work, what would be the advantage(s), if any?
