Use "disk management". I think its supported in read only, however.

When I was messing around with that 64 gb Adata card, I was able to see it on my win-98 system when I took it right out of the original package and plugged it into the card reader. I didn't perform any sort of formatting command on it at any point, and it hadn't been plugged into any device (like a camera) that would have formatted or re-formatted it. So my experience points directly to the fact that it came from the factory formatted as FAT32, and claims that SDXC cards *must* be formatted as Ex-fat are complete bullshit.

And nobody here has as of yet answered whether or not a default installation of Windoze 7 is Ex-fat aware.

Oh, also to mention a slightly different point, reportedly Win 7 allows you
to format FAT32 onto an SXDC card ;

"I've plugged my ADATA 64-gb card (which claims to be SDXC) into an HP netbook
with integrated SD slot and windows 7, and it reports the file system as FAT32.
"
But you didn't say whether your Adata, before plugging it in, had the original OEM
formatting, or whether it had been used in some other device which may have
been used to (re?)format it to FAT32 (mp3 player, digital camera, etc.).

The main thrust of your line of questioning seems to be, does the SXDC spec strictly
require exFAT for SDXC of 64GB and up?
We could answer that if we had a copy of the SD Association's "File System Specification"
document of (near as I can tell) Version 3.01 or higher. (Neither you or I are The Finder,
so no answer thus far.)
Even then, I'd venture to theorize that the deciding factor is more what any devices'
manufacturer has set in their firmware, as to whether a device would read or instead
have problems with an SDXC 64GB and up formatted in FAT32...
Mmmm, random example, reportedly the HIFIMAN HM901 music player has no problem;

Has anyone here ever connected an SDXC flash card to a Win-7 or linux (or what-ever) system and actually verified the file system on the card?

All the web-searching I've done comes back with people making the same statements - that SDXC cards 64 gb and larger come pre-formatted as exFAT. I've plugged my ADATA 64-gb card (which claims to be SDXC) into an HP netbook with integrated SD slot and windows 7, and it reports the file system as FAT32. Does win-7 come with exFAT awareness built-in - and hence it would report the file system on the SD card as exFAT if it really was exFAT?

Ok, so I picked this up at a local computer parts store:

http://www.ultraproducts.com/applicatio ... No=8210281

ULTRA 3.5" Internal Media Card Reader & Writer - 5 Slots, SDHC / USB, Black/Grey (U12-42951)

Ultra says it's a discontinued product, but I picked it up locally for $12. I plugged it into a motherboard USB port and my win-98 system detected it and loaded the drivers - I wasn't asked to supply or locate any files.

I plugged in a few low-capacity SD cards (2 and 4 gb) to make sure it works, and then I plugged in an ADATA Premier Pro 64 GB SDXC card. And yes - my win-98 system was able to see it just fine. Drive properties says 64,592,150,528 bytes, FAT32 file system.

I copied a 1.8 gb mkv movie to it from one of my SATA drives. It took just under 3 minutes, which worked out to 10.8 mb/sec. The ADATA package says this SD card is rated for 95 mb/sec read and 45 mb/sec write. I played the movie from the SD card (using VLC) just to make sure the copy was ok, and it played very well.

So here we see that SDXC memory cards and card readers are fully compatible with win-98. I'm going back to buy a few more of those readers for all my other win-98 systems.

There's no reason it has to be exFAT, I am quite sure Linux people put their favorite *nix file system on these cards.

Win-98 compatibility with SDXC memory card readers?

98 Guy, 2014-07-14 17:23 »

I understand that Secure Digital memory cards (SDHC) can have a max capacity of 32 gb, and beyond that you have SDXC which can go to 2 TB.

If I understand SDXC correctly, they *must* be formatted as exFAT - which is proprietary to Micro$haft and which must be licensed. Maybe someone can explain why FAT32 wouldn't work just as well, given that it too can be used up to 2 TB.

So I'm looking for an internal drive-bay card reader that can read SD cards larger than 32 gb, and I'm wondering if there are any out there that have win-98 drivers.

But also - can I format an SDXC card as FAT32 and will it work in my digital camera?
