(yes, this is related to the thread I just posted, but figured it was worth asking as a standalone question)
An external drive I'm using supports eSata, USB and Firewire interfaces. I'm currently using eSata, but am having some problems. Can I switch to USB without "readding" (ie, formatting) the drive?
Yes. Windows Home Server writes an identifier to the drive, so it will be recognized however it's connected. I'm not on the WHS team, I just post a lot. :)
