Status Report:DISK Error Notification:Error:Read error

[AppliedIT]

Hello All,

 

I have a brand new Buffalo NAS Quad and 4x new Western Digital 3TiB drives. Recently I decided to reboot it via the web interface.

 

When I did, I was sent eight emails that said this:

 

==========================================================
Subject: LinkStation Status Report:DISK Error Notification:Error:Read error

 

DISK Error Notification

 

HDD error occurred

Disk(s) the error occurred:UnknownDisk(mtdblock1)

 

(mtdblock1) READ sector:32752 count:1

Disk writing error

Continuous backup is recommended.

 

[LinkStationInformation]

 LinkStationName: LS-QVL2E3 (LS-QVL)

 Time: 2012/09/09 18:05:18

 Setting Screen: http://192.168.1.252/

 ==========================================================

 

Each email was sent about 10 seconds apart and incremented the "count" above from 1 to 8.

 

I've searched these forums and others have had similar emails but theirs included lines such as "RAID drive error will be repaired automatically" or "Some data may not be recoverable. Immediate change of disk is recommended".

 

However my error had no such line as you can see. In the interface no drive is in an error state so I am unsure what is going on, what drive is faulty, if it needs to be replaced, or anything!

 

I emailed support and after some chasing up their reply was that these emails *may* not be a problem, but I wasn't inspired with confidence considering I have important data on this device.

 

Please help! Any advice would be greatly appreciated.

Do you have a USB disk or USB device connected to the Linkstation?

[AppliedIT]

Hello & thank you for your reply. No, there are no USB devices attached to the NAS whatsoever.

Then reset the unit to factory defaults via the web admin page (System -> Restore/ Erase -> Restore to Factory defaults)

[AppliedIT]

I have 4TiB worth of data on the NAS so far, and I have spent a lot of time configuring it.

 

Do I really need to reset to factory default? Why can't Buffalo documentation or support clearly explain what these email means?

 

Have I lost data? Is one of my drives failing? If I have to reset to factory default, will I loose any data?

 

This should be a lot easier to figure out.

 

Thanks for your advice, I appreciate the support.
