Replacing Faulty Hard Drive With New Larger One

I have a RN102 Currently there are 2 seagate drives in it 1, 1TB and 1, 2TB

The 1TB is Failing there is an increasing number of errors in the logs and ive noticed some performance degradation.

The Drives are Setup as 1 "RAID JBOD" Volume. what is the best way i can remove the older drive and insert my newer larger drive without loosing files.

    You need to copy off the old files, then delete the current volume.

    After that insert a new drive, and create a new volume (and restore the data).
  • There is about 1TB on the NAS i dont currently have a drive outside of the NAS to store this, is there anyway i can unlink the drives and copy all the media onto the good 2TB drive?
  • No there isn't. You will need to do what StephenB has written.
    You have encountered a problem that illustrates why a non raid volume across multiple disks can be risky.
    If the disk had or does does fail you would lose the entire volume's data.

    You should have a backup of any data on this setup unless you are happy to lose it all one day.

    Something is inconsistent here. JBOD means "just a bunch of disks". If you are set up as JBOD then you have 2 volumes, one per drive, and they are not linked.

    Can you clarify - do you have only one RAID volume? If so, is it RAID-1 or RAID-0?
