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.
Really nice try though, any other ideas?
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 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.
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
