Thank you

When I click the link it tells me 'access denied' and that it may be to do with my computer not accepting cookies ...never had that before, and it does accept cookies - still, thank you for the link to that product.
It looks very useful and will enable me to use any decent external drive! Happy!
I have two drives: LaCie Poulton and Samsung Story (both have Samsung drives I think) - both are working fine and not too old just yet, but I like to replace them every 2-3 years.
Your solution means that once I decide on a new one it doesn't have to have a switch.
Is it OK to plug one of these into a socket on an extension or does it need to be in a wall socket ?
