Using Western Digital WD10EADS-disks with the Netgear ReadyNAS Duo
I bought a ReadyNAS Duo before Christmas, and a 1TB Western Digital disk (WD10EADS) to use with it. I immediately started getting ATA errors and adding another
one (for redundancy) resulted in more of the same. Thanks to tips from mdgm over at the ReadyNAS forums, though, I know what to do:
Install RAIDidator 1.4.7 or newer (here’s a link to the beta)
This will stop ATA errors, due to TLER-errors when using certain WD disks.
Also, run the WDIDLE3-utility on the disk, this will prevent the Load Cycle Count on your disks from increasing and shortening its life. You will need to connect your
drive(s) to a desktop-computer with SATA-support running Windows. Then boot from a DOS-CD (or usb drive) and run WDIDLE3. Here are the steps:
Download WDIDLE3 from here
Download FDOEMCD.builder.zip from here
Add wdidle3.exe to CDROOT folder.
Execute MAKEISO.BAT to create new FDOEM.ISO CD image file.
Burn FDOEM.ISO to a CD and boot from it.
Run the command: WDIDLE3 /S300
I’m not sure if you can perform the last step simultaneously for both disks, but if you can’t just reboot with the second disk and run the WDIDLE3-command again.
This should prevent both ATA errors and LLC from increasing, unless your disks are actually faulty, in which case you should have them replaced.
Here is a link to the thread about this issue in the ReadyNAS forum.
