im having a problem with a removeable drive. it has previously been E: but it has just recently started being F: when i turn it on. there doesnt seem to be nething using the E: though. I need it to be in E:! is there neway i can make it assume E: instead of going to F:. when i put in another removable disk it goes to E: but the one i want to use E: doesnt go there?
