Something went wrong on the last post so I try again.
Ok thanks for the reply, with that in mind I have done further investigations these last couple of days. Bit of a close out.
On the rear label, most obvious near the MAC is stated "LS-QVL Series" lower down by the serial in small print its states LS-QV8 OTL/R5-AP. Also manufactured Jul 2012.
Running in raid 5 so no data recovery option from 2 drives.
Ssh access: login admin and session terminates when correct password is validated, probably old ssh library used in firmware which is no longer accepted.
On start, flashes blue, then goes to 7 red flashes. Network lights are active. shutdown not working, it responds to the function button by changing from red flash back to blue. The drives all power up and seek, then quiet. The fan starts and runs.
Opening it up reveals no damage or obvious fault, extender board is seated ok. All chips are warm but nothing is running hot.
I suspect because of the above the boot firmware is ok, processor appears to be up and ok and now its looking for the drive boot tracks. 7 red red flash may mean hardware issue with the sata bridge.
So If I were to bother fixing it, I would be looking at replacing the sata bridge chip first. Better to just load up a linux machine with drives, and serve them with nfs and samba and either raid or mirror (raid 1). Normal drive setups that are a damn side easier to deal with than the buffalo setup.
For what its worth, some observations on the drives from testing that may interest someone else down the track.
Putting them in a Debian pc all 4 have the same partition data as read with fdisk.
In another identical good unit each disk one by one in any slot. Pertaining to the OS or firmware partition, not data partitions, 2 scenarios occur.
A drive will boot with flashing blue, go green, ping after a minute or so, another couple of minutes it will have ssh and web access,
Nas Navi access, normal green light activity and red flash for error 16. Of course no raid array is available.
Empty drive bays show red. Any drives that come up like this will all come up together, shutdown on button press.
These drives will all come up on their original IP.I deem this a good drive on the firmware aspect.
Otherwise it will only get as far as steady green with ping, that's it. No shutdown button operation so you must pull the power plug.
Putting good drives in along with one like this does not help, the process stops at the same point. In my case that was 2 of the 4 drives.
Next I took two of these sick drives and put it in a win7 box, to be told all the partitions needed formatting.
Disk management in admin tools showed all the partitions as did Debian.
I deleted them, made a single partition, drive letter and quick format and windows is happy with it.
Next after 7 hours of disk check, both came up with out any reported errors and work fine. A good idea to use a better test than MS to be sure of this.
