Possible Disk failure

[johnneyboy]

Hello,

I have noticed a number of oddities with my N2100, keeps dissapearing of the net, well it looks like I have either a driver or disk error. I only found it by looking at dmesg, see the output below. Has anyone else seen this. I'm more convinced it's a disk failure, however the SMART monitoring, says everything is OK... so is it driver...

John

Hello,

I have just swapped over the two drives in the enclosure, rebuilt the raid (1) retested... and so far all is OK. Maybe the drive was not seated properly, time will tell..

Well, the drive has failed! no driver issue, just a good old hardware problem.

For info....
/dev/sda is the drive closeset to the main board.
