my pro business has hung up twice now on t32. Both times I had to hard power off, could not ping or otherwise connect to nas, normal front button power down sequence did not work, had to hold until power off, then I switched of the hard button in the back for a few then powered up.
the first time, it said I had a failed disk, but tested and reinserted and resynced fine.
the second time, this morning, all disks show fine but still going through a resync process.
While I may or may not have a flakey disk, I would not expect it to bring down the whole nas.
