Old Linksys died, bought as a replacement. Plugged in Ethernet cables, plugged in power, up and running, no setup. Loading files from other computers seems like from the local hard drive. Definitely recommend.
StarTech.com USB to SATA HDD Docking Station for 2
Excellent device. Easy to use. Simple USB plug-in. Was able to recover data from my system disk, which I had to replace because some blocks corrupted, and the system couldn't be recovered. New disk, reinstalled system, back up and running, but without my old data. This Docking Station let me recover it all. Watch out for other interfaces which don't work on this kind of disk (Dell Inspiron internal HDD). You can use this, with a spare HDD, as an external drive.
