RAID is not a replacement for a backup! Here's why.
I have two Linkstations on my home network. The primary (500GB) was in use the second (120GB) was idle. Needing a place to backup a share I cabled the two together with a USB A to USB A cable. The secondary is fine but I believe I damaged the primary with this approach. The primary is still up and running and indicates no errors. I can ping it with its IP address from a command line. I cannot map a share nor point a browser to it successfully using either device name of IP address. Did I fry a controller or ??? I have some data on the primary share that I really cannot abandon. Ideas on how to proceed would be appreciated.
