Raid 5 crashed

We had a power outage at the weekend. Now my NAS raid 5 array is unavailable. The html interface is available and reporting the volume is 'crashed'. Any way of recovering the data? Thanks Chris

Hi Chris,

How many drives are part of the array and what type are they? Are the drives making any unusual sounds like clicking or screeching? If not, then you should be able to recover the data. If the drives are making clicking sounds, you will probably need a professional data recovery service that specializes in Raid 5 data recovery to help you.

If the controller shows that only 1 drive is bad, you should be able to rebuild it by replacing that drive. If the controller shows all the drives are bad, then it is most likely a problem with the Raid 5 controller itself. In this case, you could try putting the drives in a working version of the same enclosure/controller.

Check the obvious also, like loose connections to the drives. Whatever you do, dont force a rebuild as this will probably result in permanent data loss.

Well from a SUN StorEdge 3510 RAID controller, there should be an option to rebuild your RAID 5 set. Do you see in your html interface a failed drive? Hopefully it is only one drive. Did you have any local or global spares assigned to the RAID set?

FAIL-SAFE FILE SERVER AND COMPUTER SYSTEMS If your data is very important, you...


If your data is very important, you should consider doing regular data backups because hard disk will fail at some at some stage in the future. This is especially true when you get an error message"hard drive is about to fail".

Depending upon how critical your computer or files server to you or your business, you should consider building a fail-safe computer or file server system using RAID technology. RAID means "A Redundant Array of Inexpensive Disks" and there are several levels of RAID.

For details of different RAID levels - click on this link -,,sid5_gci214332,00.html

The most common of the fault redundant RAID systems are -

RAID 0 + RAID 1 provides fastest data transfer Mirrored hard drives.

RAID 5 is one of the most popular system, it data striping across hard drives with error correction. It has excellent performance with fail-safe system and allows for hot swappable hard drives.

There should be redundant powers supply inside the computer or file server in the event of a power supply failing.
Another consideration is to install a UPS (uninterruptible power supply) to prevent a computer or server shut down from power outages, as this will corrupt your data.

These systems do not mean you should not back up your data on a regular basis.

I have a usr8700 NAS running raid 5. I had a drive fail and now I cannot access any of the data. I am researching the options of recovering the data. I found a few products and service options but don't...

Hello, I don't know your particular NAS, but a raid 5 is able to survive a single drive failure and continue to supply data ok because it recreates it from the remaining drives plus the parity drive. But, if you then get a subsequent drive failing before you've replaced the original failed drive, (and restored the data to it, which is/should be automatic) then it's really bad news. So, if you definitely have only had a single failed drive then you should just get an alert to warn you to take remedial action- ie, replace the drive. If the NAS has stopped supplying data then you may have got a multiple-drive failure situation. Just a general note of caution when working on a raid array: Some raid systems are clever and you can switch your drives around, some aren't and you can 'break' these raid sets just by swapping the positions of 2 drives, which is too easy to do if they're not labelled and you're trying to faultfind unless you're absolutely certain, just label your drives (and take a photo) before starting to swap drives about. Anyway,good luck with your troubleshooting.

How we know RAID 5 subsystem going to failed one

The manufacturer of the RAID interface-card has software that can be installed to monitor the RAID, and to identify any "failed" disks, and to "rebuild" the RAID array after a new disk-drive has been added to the array.

Did you try to boot the system without all the harddisks inside (keep at least one).
This helped me to bring up the NAS-T4 up again.

Hard drives freezing up

Damaged drive controller on HDD a possibility. Pull drive and test as a slave to rule out a bad RAID controller. Let me know if the drive is failing under SMART setting in system BIOS upon boot.

There's a 9-pin serial connection on the back, can you use that connection to a terminal to see anything? Also, if you don't have access to the manual, visit this link to download the manuals:
