Although I am reluctant to admit it, my problem is probably an almost dead usb key. Here's the story, so far.
I created a bootable key of Backtrack 5 using YUMI from Pendrivelinux. Choosing USB as first boot device allows me to access the key and choose to boot BT5. It doesn't seem to boot up properly but at least I can access the drive; so I should be able to format it, right? On booting to both/either Win7 or Ubuntu 11.04, the drive isn't mounted. Under Win7, it's available only under Device Manager as an Unknown Device and comes complete with exclamation mark! It also seems to be listed under USB Controllers as a USB Mass Storage Device (properties say Device working properly!). There is also no listing of the drive under the Disk Management section of Administrative Tools/Computer Management. I have also tried Spotmau but the drive still doesn't show up. Any ideas of how to format the key? There is no data worth saving on it, as it can easily be rebuilt, but it's a handy 4Gb Kingston Datatraveller 102 stick.
