Hi,

I purchased a Patriot 16GB SDHC Class 6 card. My TT 720 only recognizes 3.3 GB... Is there a way to have it see the full size?

Until it does I'll be using the card in my camera so I don't feel to bad about purchasing the card.

Thanks

Format it to FAT32 in a card reader and put data you want on it using Explorer, not TTHome.
 
FAT 32 and the Macintosh

Format it to FAT32 in a card reader and put data you want on it using Explorer, not TTHome.

I can easily borrow a friends windoze box to format a card to FAT 32 (Mac Disc Utility does not offer that as an option), but can I them easily pass stuff back and forth using my Mac, or will there be problems?

As I understand it, the 720 will read data beyond 4 gigs on a sd card, just not write to it. So, if one uses Explorer on a pc or equivalent on a Mac to put stuff on the card, once formatted, the 720 should be able to read it.
 
Well using a sd card reader with Explorer is the solution. I can now use my 16 GB card in my TT. :)

Thanks
 
I formated my SD card using Vista. It only did format 15GB instead of 16, but it did the trick.
 
There's actually a sneaky reason your card only formatted to ~15gB. It's marketing. They used to give you the size in formatted size (i.e. one kb = 1024 bytes) but some marketing person said we can make our devices look larger if we use 1000 bytes = 1kb. and 1,000,000,000 bytes = 1mb and so one. Of course when you actually want to use it and format it. that extra 24 bytes per k gets you.
 
how could I fix it?

You can't.

It's like they sold you a bookshelf that was labeled as a 5 shelf bookcase, 3 ft wide. You think, 15 ft of bookspace, cool. Then you get home and realize you only have 3ft 11in of shelf space per shelf because they measured the outside width, not the inside width. So you actually only have 14ft 7in of bookspace.

Pedro, it's the same thing you have to deal with concerning computer hard drives. For example, a 160 gig hard drive, when formatted, will never have 160 gigs of storage space. For example, this is the story for the hard drive in my computer:

So much for having a 80 gig hard drive. :eek:

Just a reality of storage devices.
