Replacement procedure for suspect drive in ReadyNAS Pro BE
BACKGROUND: ReadyNAS Pro Business Edition with six WD 750 GB enterprise drives (WDC WD7502ABYS-01A6B0), all drives with 03.00C05 firmware. The drives show about 57,000 runtime hours (about 6.5 years...

Tested drives again with WD Lifeguard Diagnostic for Windows; both show PASS.
Both drives show no SMART issues (all zero's in expected warning indicators).
Does RAIDiator 4.2.27 keep an internal database of drives and serial numbers with capability to reject drives based on database history? (although neither of these drives are actually failed).
Thanks, gregb

I am still looking for a solution to return the device back to 6 active drives (X-RAID2).
WD Lifeguard Diagnostic shows two good replacement drives: one drive with 57K hours and one new drive.
Both pass WD Lifeguard Diagnostic tests, both have zeros written to all blocks, both show good SMART data.
However, for both drives, ReadyNAS Frontview status indicates "Newly added disk has failed SMART test" when inserting into bay 1 (as noted in previous posts). The "failed SMARTtest" message doesn't show up in system.log.
Old drive:
Raw Read Error Rate 0 Spin Up Time 1133 Start Stop Count 29 Reallocated Sector Count 0 Seek Error Rate 0 Power On Hours 57150 Spin Retry Count 0 Calibration Retry Count 0 Power Cycle Count 27 Power-Off Retract Count 10 Load Cycle Count 29 Temperature Celsius 43 Reallocated Event Count 0 Current Pending Sector 0 Offline Uncorrectable 0 UDMA CRC Error Count 0 Multi Zone Error Rate 0 ATA Error Count 0
New drive:
Raw Read Error Rate 0 Spin Up Time 1200 Start Stop Count 8 Reallocated Sector Count 0 Seek Error Rate 0 Power On Hours 140 Spin Retry Count 0 Calibration Retry Count 0 Power Cycle Count 6 Power-Off Retract Count 5 Load Cycle Count 8 Temperature Celsius 33 Reallocated Event Count 0 Current Pending Sector 0 Offline Uncorrectable 0 UDMA CRC Error Count 0 Multi Zone Error Rate 0 ATA Error Count 0

I am wondering if the SATA port in the NAS itself has failed.
Can you try powering down/removing the existing drives. Then insert one of the new drives into the NAS into slot 1, and see if you get the same error?
If you do, power down again and try it with the drive in slot 2.

Drive 1 was already removed; system was in degraded mode for several days without drive 1 (drives 2-6 active).
Write full zeros to disk 1 (again) using WD Lifeguard Diagnostic for Windows. Good SMART / passed.Action completed on 01 Sep 2015:
Shutdown, insert disk 1, and power on.
Different behavior than shown above last week (Fri Aug 28). Odd:
Front panel showed this set of four messages sequentially several times:
Testing Disk 1
Disk 1 Passed
Disk 1 Failed
Volume C degraded
[repeat]
then finally:
Resync in progressAlthough I really didn't fix anything, the system appears normal again.
Thanks, gregb
