Hi all,

I have a problem with my:

LS-WVL4TB

Firmware version:1.64

The drives are 2x2TB Western Digital.

Running in a Raid 1 array.

I came home the other night and the device had switched itself off. It was on when I went to work.

I tried to power up but was presented with a blinking red light.

One long than one short flash.

I reviewed the NasNavigator and it read E11 which is a fan issue.  The device is in EM mode and the firmware is flashable. Yet a firmware flash doesn't recover the drive. The flash completes then reads something to the affect of "Flash didn't recover drive reverting to em mode."

The fan is spinning and generating a draught.

NasNavigator is reporting that drive 2 is showing a high level of bad sectors, but even that's weird as it's says this regardless of if Drive two is in the NAS or not.

I have reset the device through the function button at the back, which made no difference.

What do you think the problem could be:

• Has the fan which appears to be spinning given up, if so can I buy and fit a replacement?
• Are both or even one of the drives on their last legs, if so will flashing and formatting the partition restore them. I'm loathe to lose all the files and then have to copy them back over which takes days.
• Or is the ProDuo itself on its last legs.

Is the bad sector report a true estimate? I ask because when I connect the drives to my PC and use UFS navigator I was able to pull all the information with no real problems.

It's a strange issue, I have had similar issues in the past but flashing the firmware always kicked it back to life.

I will obviously try formatting the drives tonight through the liveupdater, but wondered if anyone had any suggestions, especially as the E11 is reporting a fan issue.

Many thanks for any thoughts or feedback
