Configuration:
- Two Seagate 1.5TB drives
- RAID1 configuration
- One volume (Volume_1)
- Firmware 1.09
Symptoms:
- In Oct & Nov, I received several automatic emails that a drive had failed but there were no failure lights on the front of the enclosure nor failure entry in the log.
- Disk Tools->Scan Disk reported "Volume_1 FAILED" after just a few seconds, but no indication as to which drive
- I ignored it for a couple months (but kept a good backup!)
- Last week I manually rebuilt the RAID; no changes except...
- The log now shows HDD2 has failed but there is still no failure light on the front of the drive; all lights continue to be blue
- Disk Tools->Scan Disk still reports "Volume_1 FAILED" after just a few seconds, but still no indication as to which drive has supposedly failed
- The NAS drive seems to be operating normally otherwise
Without a failure light or drive bay labels, I cannot tell which is the allegedly-failed drive. Which drive is HDD2? The drives are under warranty for almost another year.
I do not know what to do next. Please advise.
