May 4, 20179 yr These are drives I've used for a while, they have been tested earlier with other tools. I will also not be using a parity drive (most of the data on these is backed up, this is a new unRaid system I'm building, parity will be added later). I think unRaid at a minimum wants to write a 0 to every sector? I don't want or need a stress test. What's the fastest way to do this? Is the 'clear' in unRaid UI faster than the pre-clear script?
May 4, 20179 yr Take a Drive, put it in a PC, remove all partitions and erase the first 50-100GB (with zeros). Then connect it to unraid and let it make a partition (XFS prefered) - done Edited May 4, 20179 yr by Zonediver
May 4, 20179 yr Community Expert Clearing is only needed when there's parity, without it you just need to assign the disks and format them after starting the array.
May 4, 20179 yr Community Expert And even after you add parity, unRAID only requires a clear disk when ADDing a disk to a NEW slot. This is so parity will remain valid. A clear disk is all zeros and so has no effect on parity. When replacing a disk, unRAID does not require a clear disk, since it will be completely overwritten from the parity calculation.
