Are the replacement drives brand new or have been used?
You probably need to contact support for this.

Do you have a backup of all the data stored in the NAS?
Have you tried to reboot the NAS?

You may isolate the problem by performing a disk test to the replacement disk. You may use either Seagate Sea Tools or the Western Digital Data Lifeguard Diagnostics for Windows:

Otherwise, just like Nhellie has mentioned, you might need assistance from Netgear Support: http://support.netgear.com/general/contact/#tab-call

Is the replacement disk in slot 4?

[dragos1]

Yes the replacement disk is in slot 4 and it's brand new.

[StephenB]

So it's not just stuck at 0%, it's listed as "dead".

Perhaps first confirm the disk status with RAIDar.

Assuming it also says the disk is dead, then I agree you should start by testing disk 4. I think WDC lifeguard will test hitachi.

Also, it would be good to make/update your backup.

Thank you for your help, It is indeed the hard drive. Brand new and bust. We do have a daily backup
