hi,

firstly, please refer link below:

event  58 – disk signature of disk n equal disk signature of disk n

http://www.sysadminsblog.com/microsoft/event-58-the-disk-signature-of-disk-n-is-equal-to-the-disk-signature-of-disk-n/

note: microsoft providing information convenience you. please make sure understand risk before retrieving suggestions above link.

besides, did you fully initialize disks in each striped volume? when initialize new disk, disk management make sure there no duplicate disk signatures.

in addition, can run “chkdsk” check if there are corrupted data on disk , run “chkdsk  chkdsk [volume letter]  /r” command repair corruption.

best regards.
