Logs report errors such as... | |||
* [RAID5 Disk Volume: Drive 1 2 3 4] RAID device in degraded mode. | |||
* [RAID5 Disk Volume: Drive 1 2 3 4] Drive 4 removed. | |||

* [RAID5 Disk Volume: Drive 1 2 3 4] RAID device in degraded mode. | |||
This can mean a failed drive, however it can occur as a false error, whereby the disk fails to respond as quickly as the NAS expects. Search Google for similar errors for your specific disk model to ascertain if its likely to be a recoverable problem. | |||
To recover... | |||
