I just bought a SanDisk Extreme USB 3.0 Flash Drive (64GB) yesterday, when i plugged it in my PC, i can see the files inside. ie. the Club Sandisk thing. but i wasnt able to copy anything on it, so i tried to reformat it to try my luck and nothing had happen, the drive now is just a drive that can only work after being formatted. but now i cant reformat it...

New USB flash drives don't need to be formatted. They are formatted at the factory.
Important files = Backed up files

To my knowledge all flash drives come formatted as FAT32. The only reaosn one would need to re-format to NTFS is if they needed to transfer a single file over 4GB in size.

I have the same problem with 2 drives of this model. Tired formating on 2 PCs (one XP, one Win7) and cannot format to NTFS even with Diskpart in command mode. The drive also cannot be read in MAC (one 2011 w USB 2 and another 2012 w USB 3). Partition or format in MAC fails.
Shop will not refund, called technical support and was asked to get replcaement which will not solve problem. Need Sandisk to provide a solution for:
1) format to NTFS
2) MAC OSX compatibility

Just got a 64 and a 32gb in the mail and they were strangly dropping out then back on when connected to usb 2.0 every know and then but when plugged into usb 3.0, where I have a usb 3.0 dock w/hdd that work great, it would just pop in and out ever few seconds. Made the mistake of thinking something might be up with the data on teh drive so I did a quick format and of course it would effectivley just sit there and fail no matter what setting I used and is now useless.

Should have mentioned, for what it's worth, that the systems I tried it on were a windows 7, windows 8 rtm and windows 8 CP. All 64 bit. All same results. Saw people with Mac's and XP having simliar issues in other forums.
