why does w7 want always format a truecrypt partition ?

hi

why does Windows 7 want always format a truecrypt partition ?

i have an external hard disk

2 partition ntfs file system

1 was encrypted with truecrypt 32bit under Windows 7 32bit

everytime , Windows 7 pop up with a request to format the drive

i don't auto mount the partition , i mount the partition always when i need

so when the partition is not mounted , Windows 7 asks me to format

it's very boring

can i avoid it?

thanks
cheers

ps this doesn't happen with xp

 

Go to the Computer Management > Disk management and remove the letter Windows is setting to this partition, i.e., it will be a drive not mapped (without a letter).

 

Because it is seen as RAW. Do the above mentioned procedure.
