dealing with RAID error on Linkstation

[alanr]

I have a Linkstation LS-W2.0TGL/R1-V3. A couple of days ago, it gave an error that an error in a RAID array had been found. I followed the instructions and restructured the disk, but I'm now getting the error again. If I restructure again, presumably the error will occur again - is there any more permanent solution? 

 

Thanks

replace the disk.

[alanr]

excuse my ignorance here, but can just one of the disks be replaced? and, if so, must it be replaced by an identical spec disk?

Same disk size and rotational speed as well as cache if possible
