Hello

two scsi 73gb in bay 0 as raid 0

Could you restate the information you provided. Are you having issues with the drives being detected or are you having issues importing a set of RAID 0 drives onto a different controller? Are the drives showing up in the physical disk list of the controller?

is this a bad hdd that is bad or backpanel board

I can't say for sure based on the information.

Thanks

When i have hdd id 0 it does nt shw up or power up but when i swap to id 1 it power up on both of them i dnt get nothing in id 0

I would suspect that it is an issue with the backplane if the drive works in slot 1 but not slot 0.
