Disk notations:
• S0,S1, ..., S[x] - every disk with S notation is one of SATA / JBOD / RAID units.
• H0,H1, ..., H[x] - units with H letter are IDE units.
• MD0,MD1, ..., MD[x] - this way are softRAIDs denoted.
If the unit is already added, it can not be removed it in Web management. Units that are
already used in a volume group can be made available again by using function Delete content
of units under console (Ctrl+alt+x). Be aware that this will remove all data from a Unit! You can
only use units with capacity greater than 5 GB, smaller units are not supported.
Function: Drive identifier
This function helps find disks in the cage of your NAS server. In case of hardware RAID
installed, the whole RAID array is shown as a single drive. In this case you may not be able to
determine which drive unit is which disk when using S.M.A.R.T. tool or hardware RAID
management tool (depends on manufacturer of RAID controller).
