ReadyNas NV+ Dead Drive

I have a 4 drive ReadyNAS NV+ and a drive in slot 2 reported it was dead. I have subsequently replaced the drive with a drive of the same size but the model had been superseded. Every time I insert the new disk, it is recognised but then an message comes up saying "The disk attached to channel 2 could not be used. The most common reasons are RAID resync in progress, faulty drives, and disks that are too small to be added to the array."

The status viewer shows the new drive as being recognised with the same size attribute but cannot add this to the array.

Rebooting does not work when the new drive is plugged in. I can reboot it without the new drive.

Any ideas on how to get the new drive accepted into the array?

    If the new disk is one byte smaller in capacity than your other disks it would be rejected (this has been discussed elsewhere on the forums).

    Is the new disk you added, a blank unformatted disk with no partitions on it?

    Did you check to make sure the replacement disk was healthy before adding it (e.g. hooking a SeaGate disk up to an internal SATA port in a PC and checking it using SeaTools - or similar tools for other brand disks)?
  • The new drive was received today and I did not check it before plugging it in. I can check with the SeaTools, but how am I supposed to see if the drive size is incorrect?

    Hook the drive up to a PC, check it (e.g. For a SeaGate disk use SeaTools) delete any partitions on the disk using "disk management" (I think) and then try adding the disk to the NAS again.

    Likely it won't have any partitions, however it is worth checking.

    Right-click on "computer", and select "manage". Disk Management appears under storage (left pane). The disks will be listed on the right. If there are any partitions, right-click on them and delete them.
