Problem

I've started using TrueCrypt to encrypt a partition on an external USB hard drive. I've opted for using a raw partition as opposed to a file container. But here's the annoyance. Whenever I connect this drive to a computer running Vista or Windows 7, I get the message popup "You need to format the disk in drive J: before you can use it". The default option is "Format disk", and I'm afraid one of these days I'll accidentally trigger it. Is there any way to disable this message?

Fix for: How do I disable "you need to format this disk" message in Windows Vista/7?

Low Risk

Try to go to the Control Panel - Administrative Tools - Computer Management. In the Disk Management part, remove the drive letter for the raw partition. It should prevent Win7 from asking you to format the partition, while letting you mount the partition in TrueCrypt. If it doesn't work, you could try this suggestion, which is to use Autokey to automatically dismiss the messagebox when it appears.
