ML330G3 raid 0 failure offline array AGAIN

[Darko_7]

Dear Sirs,

1. There are 3 disks in the system: one master IDE disk with the OS, and 2 IDE disks striped into RAID 0 configuration.
2. The master disk and one of the RAID 0 disks (the good one) are on the same IDE channel: the master disk is master, and the RAID disk is slave; the fault disk is master on the second IDE channel
3. In meantime we have inspected the disk and electronically is OK, we have made a byte-by-byte copy to another identical disk.
4. The raid controller is setuped by MegaRAID
5. The server can be booted and the OS is working ok with the master disk
6. In the boot sequence, all 3 disks are recognized, the raid controller puts the Array0 (the master disk) online, but the Array1 (two disks in raid0) offline.

So, the question is: what will happen if we reinitialize the array1 (will the data be lost?), OR can you state us any other solution (upgrade of the raid controller, ...)?

Thank you
