Explanation

I received an error message on my NAS LS421DE, it indicated that the disk 2 was defective
I bought another disk of the same value as the defective 5Tb

I changed the disk to try to rebuild the raid (it did not work) but I realized that I am in raid0 so
I can not rebuild my raid0. (read on google) and,
I unfortunately umount array raid0 error in Web Application LinkStation

My question, is it possible to put my original disk 2 and recreate  raid0
and rebuild raid0

Currently I have this configuration of my NAS Buffalo LS421DE

Disk 1    Unformatted   TOSHIBA DT01ABA3    2779.8 GB
Disk 2    Unformatted   ST5000DM000-IFK1   4642.4 GB
I did not do any format Disk

Do you have solution? Need help please.

Sorry for my english !

If the disk is faulty then the data and the RAID is gone, mdadm won't resolve this.
PM me for TFTP / Boot Images / Recovery files  LSRecovery.exe file.
Having network issues? Drop me an email: info@interwebsireland.com and we will get it fixed!

Have i helped you? Buy me a coffee as a thanks!

RAID 0 has no redundancy and cannot be rebuilt.
