Is a 64 GB Flash Drive Compatable?

I have a IMac I bought in early 2009. I think it is 19 inches. The OS has been updated to Mountain LIon.

A few months ago I bought a 32 GB SanDisk flash drive and used it with no problems.

This week I bought a 64 GB SanDisk flash drive and my computer did not recognize it. Is 64 GB too big for my IMac?

The new flash drive is either defective, or the 64 GBs is too big for my IMac. Which one?

Note: I bought the flash drive at an office supply store. When I brought it back to return, an employee tested it on their WIndows equipment (they don't deal with Apple), and found that the flash drive was OK, at least for a PC. Someone else at that store thought that 64 GB might be too big for my IMac.

Before I went back to the store, I contacted SanDisk for online chat. SanDisk thought that flash drive should work with my IMac, and said I should just exchange it for another one.

But ARE We? I see no link to the actual Thumb drive the OP is talking about and since the Mac is Not seeing it that would lead me to think it is not what you are thinking a Flash Drive is but a SD card.

Or simply the OP has a problem with his USB port or ports.

Ok I haven't read the whole thread, So it is showing up in Disk Utility then?

You format a SD card the same way as any other drive. But if it is showinig in Disk Utility then it is more then likely not a XC SD card. As that wouldn't even show in DU as the reader can't see/read that type SD card.

OK I'm out of here.

Good Luck to the OP.

As I mentioned, the size of the drive shouldn't be a problem.

How is the drive formatted?

Unless I've lost it completely, we've been talking about flash drives, not SD cards:

Well, he did say my instructions for formatting worked, so I am reasonably sure we are.
