Hi,

I installed 2 identical WD hard drives in a single firewire enclosure. When I connected everything to my MBP and turned it on, Disk Utility saw it as one large hard drive (1TB, instead of 2 500GB). Is this normal?

Another question: why I can't I make a raid out of this?

Thanks

It's called disk spanning, and it may be a hardware RAID. It really depends on the enclosure - what kind is it?

I got it from FireWireDirect. I, somehow, didn't notice the following blurb on their site:
With transparent, built in FireWire800/1394b RAID-0 Array (not spanning or JBOD), the PRO Z-RAID was designed to immediately start helping digital video & audio content creators, graphic pro and prosumer as well as digital data storage solution. Based on the industry leading Oxford 912 chipset base w/ onboard RAID level-0, which appears to any Mac, PC or Linux workstation or laptop as a single big and faster FireWire800/1394b disk drive.
That would explain things

Thanks for the reply

No problem - RAID is a nice surprise, isn't it?
