My external SSD has also become a brick. My Acer travelmate 2450 has an IDE harddrive which I decided to replace with an external usb Kingston SSD drive. I cloned the IDE drive to the new SSD. I decided to remove the native IDE drive since I could not get into the BIOS to change the boot sequence to USB first. Started up the computer with only the usb drive attached and it worked beautifully for a week since I always plugged the drive into the same USB bus. Footnote: I'm still on Jaunty, Karmic would not boot up for me.
Then I moved the drive to a different usb bus before startup and the system does not boot up anymore, even when attached to the original usb bus. Says "operating system not found". Popped in a live cd, but can't mount the SSD drive. Booted up with the old IDE drive and still can't mount the SSD drive. I also can not see it with fdisk -l.
The output of dmesg:
