RAID Array is toast… (Update)

My Buffalo LS-QL R5 8TB started failing in September. Since that time I have re-formatted the unit, tested the drives (no problem found), re-formatted again, re-flashed the firmware (Lots of fun finding that..) And through it all been completely unable to get any response out of Buffalo Tech.

I thought I had everything squared away but the unit died again after 10 days of operation.

I’d happily change the disk IF I COULD FIGURE OUT WHICH ONE!

“Unknown Disk”??? How is that possible?

NAS Navigator for Windows appears to be accurate (more or less)

NAS Navigator for Mac reports:
“Unformatted / Unconnected” at the same time the drive is in fact running. and also reports “E13: An error has occurred on RAID ARRAY 1”

But that’s it! Nothing specific enough to actually diagnose or correct the problem.

I’m really not up for doing the math to figure out which drive that sector is on.

All the drive indicator lights are green and the drive is doing a disk check after powering down due to the error. I was hoping that at least one of them would be flashing red.

Buffalo Technology is not interested in providing products that are reliable or serviceable. This can be easily illustrated by reading their support forums, if you can… Some of the comments from the buffalo support team are far less than customer oriented and in some cases downright nasty.

Their software is buggy, and they do not appear interested in updating anything to correct their deficiencies.

If I had to do it again, Buffalo Technologies equipment would not be anywhere on my list of potential purchases.

If you’re looking for a NAS… Look at another manufacturer.


————– UPDATE —————–


After fooling around more with the Buffalo unit and at one point “BRICKING” the array and it’s enclosure entirely. I have identified that 3 of the four drives consistently fail. This is after having formatted and tested the drives on another computer and each of the drives reporting no errors. I did figure out that (sda was drive 1 buy moving it to slot 2 where it became sdb.) You know… I didn’t want to guess about that and with 3 drives reporting problems I wasn’t wanting to make any assumptions. It appears that Disk 1 is sda, Disk 2 is sdb, and so on through sdd. That might have been bloody useful to actually PUT IN THE FAQ on the Buffalo Web site. Even a simple “yes that’s the way we report a failure.” would have been helpful.


A 75% drive failure in the same enclosure is interesting as hell to me especially where there has been no abuse, vibration, or other factors outside of normal operation. This is well beyond what the MTBF numbers say should happen. Nonetheless, when the drives are all put back in their array, they fail I’m now two for two and am calling the 3 drives toast.


I think it’s suspicious that the failure occurred on all three drives at the same time. But then again I’m a suspicious kind of guy.


So now I’m left with spending $165 per drive to replace them, thereby bringing the Buffalo unit back online and wondering if there’s something else going on… Or I could just bite the bullet and replace all 4 drives and hope the problem isn’t in the enclosure itself….


OR I can purchase a WD 3TB Mybook NAS. It’s non-raid but apparently Buffalo Technologies RAID5 array isn’t as redundant as its supposed to be. 


On the upside… I have significantly LESS data to worry about now anyway.


If I could buy 4, 3TB drives and put them in my existing Buffalo enclosure I’d consider it, since it would be an upgrade. BUT Buffalo technologies isn’t updating the firmware on my enclosure so that’s not an option.


TO BestBuy Boy Blunder! …………………………………..


I now have a nice happy WD 3TB My Book Live plugged into the port the Buffalo Tech unit used to occupy.  I paid 200.00 for the new machine. I have several ports open on my maser switch so If I need additional storage space… I’ll buy another 3TB and move on.


Yep, no RAID but as long as I’m going to have to backup the data to another media anyway who CARES?

I noticed some variant OS builds on the net for the Buffalo enclosure. Maybe if I get really bored I’ll flash one of those to the unit and see if someone else’s FREE implementation works better than the factory build. I’m going to have to be REALLY BORED!

By really bored… I mean so bored that masturbation is off the table… AS IF!

Again if you’re looking for NAS devices… Avoid Buffalo Technologies.
