I bought 2 3tb Red drives this month. 1 to replace my 1.5tb drive in my Qnap TS-110 NAS and the other to use as a backup.
I installed a 3tb hard drive in my NAS and then used the usb port via a caddy to connect my other 3tb drive to backup using raid 1 (Q-raid 1).
After about 30mins I get this error - [HDI_ROO] I/O error, sense_key=0x0, asc=0x0, ascq=0x0, CDB=2a 00 99 66 a9 f0 00 f0 00.
The USB drive is then disconnected. I cycle the power on the caddie and it carries on backing up for around 30mins before the same happens again.
I connected the drive up to my pc (win 7) and did a full surface scan (chkdsk) with no errors. I also used Western Digital Data LifeGuard Diagnostics and it passed the quick test.

I posted on the Qnap forum too and they pointed me to here. http://forum.qnap.com/viewtopic.php?f=15&t=96912&p=429262#p429262
I’ll run the extended test tomorrow, but any help in the meantime would be greatly appreciated
