This question already has an answer here:

I have this USB flash drive with a Linux partition that I use inside VirtualBox.

Each time I insert it into the USB port, windows keeps asking if it should format it.

Is there anyway to disable Windows from asking that?

Disabling auto-run has not resolved the problem unfortunately. Windows will still check if the disk contains a partition it knows about, and ask to format if it doesn't know it.

RegEdit ScreenShot

Really nice try though, any other ideas?

You could try using the registry key provided here to disable Autoplay for removable drives...

But, please note: I haven't tested that regkey and can't vouch for what it does, and disabling Autoplay for all removable drives is a bit of a nuclear option.

Alas, that's all a Google search managed to turn up.

Doesn't work. Next time you plug it in, it asks again for the drive. Why? because my USB drive has two partitions: one appears as a CD partition, in order for the autorun.inf to play and launch the decryption utility that will mount the partition Windows 7 asks to format.

In my case, the USB mounts as E: and then, if you provide the right password, will mount H: as the USB key partition. If I plug the key and suppress H:, then provide the password, the key will recreate that H: partition. Next time you plug it in, H: will be detected by Windows 7, not recognized, and Win7 will ask again to format the partition.

Control Panel..Administrative Tools..Computer Management..Disk Management

Right-click on your drive and choose "Change Drive Letter and Paths", then choose "Remove".

You could try making it recognized after all by installing a file system driver, for example Ext2 Installable File System For Windows, which also works with ext3
