Hi,
i have an addonics comtroler and 4x 1.5 Tb wd15ears drives set up as a BIG4 volume.
After a power loss one of the members is recognized as a 2.2TB so the raid won't rebuild.
I didn't find any solution to reflash the firmware to restore this drive to his normal state.
Obviously WD support wants to swap the drive and say they cannot reflash the firmware.

Please help!

Whats your goal? Why you need reflash the firmware?
I think, your should just change corrupt drive and create new array it is much easy.

It's a 6Tb raid volume and obviously no backup, recovering the firmware would allow me to recover the raid , hence the data.
If you know a way to reflash it it would be appreciated.

rgds,

There is no such thing as "reflash the firmware" for hard drives

Which drive is it that failed? How much data did you have on the array?

there was 5.6Tb of data all together drive 2 failed.
i read that wd15ears are known for this issue and that rewriting SA sector with correct data could revive the drive long enough to recover the data.
True or false?

where did this 'thing' come from?

True, in the sense that eating a pill when you are sick could make you get better.

You need to find out specifically what is wrong, have the knowledge or research to find out what you can do to address that specific problem, and then implement the solution. If you eat the wrong pill or eat too many or not enough it can kill you. Or it could be that you don't need pills at all, but brain surgery instead.

apparently a power cut is enough for the western green to corrupt the firmware...
I cannot confirm as i was away from the machine when it did append.
That i know is the drive is recognized by the bios as being a 2.2tb.
i tried to recover the data on the remaining drives with r-studio, so far not much luck ...

In this case I think the only solution is pro recovery

5.8 Tb is kinda out of budget....

Power cut as the cause ? No , simple crap drive. Anyway pro intervention is needed , but in my opinion I have the feeling the quote would not be that high, if only no physical intervention like cleanroom work is needed.
