I inherited a terrastation from a friend who replaced it when one of the drives failed.
It is a TerraStation HD-H1.0TGL/R5
The drive has no useful info on it so preserving the data is not a concern.
Do all the drives have to be the same size? I was hoping to use a 160GB drive I had sitting around. I connected the drive but the TerraStation doesn't detect it. The web interface says Drive 1 not installed.
