My issue started with problems accessing the drive. Short access is fine, but prolonged access is problematic. When backing up, the drive vanishes off the network for a few minutes then comes back on. It does this repeatedly with 30min to 1 hours of use each time. There are no visual error indications.
Second problem: in the last 2 weeks the drive keeps beeping and powering down. The fan doesn't work at any time. I presume it is over heating.
I have the latest firmware and Buffalo NAS Navigator installed.
The drive is only 6 months old. However I don't want to just send it back because it has a number of computers backed up on it and I have nowhere else big enough to store all the information.
