I have a new LinkStation Quad 4TB drive (LS-Q4.0TL/5R). Every once and a while the drive just stops responding.
The drive disappears from the network so that none of our computers can connect to it. I can still ping the drives IP address but I can't connect to it. I also can't power down the drive pressing the switch on the front of the drive has no effect. The only wya I've found to get the drive working again is to unplug it and then plug it back in.
It seems to be doing this every week to 10 days.
The drive has the latest firmware listed on the buffalo site. I've set the drive to have a static IP and I've diabled all the features we don't need (media share, bit torrent, print server, etc).
