Running an EX4100 4x6TB Raid 0 and have just seen a Bad Disk warning for disk 1.
I have just upgraded to OS5 but I am assuming it is an actual hardware issue.
I have essential data backed up elsewhere and will backup the remainder.
If I buy a replacement 6TB drive from the compatibility list is there anything else I need to know before swapping the disk? I have searched for instructions on disk replacement without sucess.
Can I run different disk sizes or do I have to use a 6TB drive or swap all 4 (something I am considering as they are all around 4 years old.)
Thanks for any assistance or pointers to threads I have missed in my search.
