Hi experts!

i have a Asus P4PE-GB.L.R, wich support Raid 0 and 1. i bougth 2 maxtor 120Gb 7200pm 8mb cache to make a raid 0 (the comp will be used for video editing). i enabled that promise controller in the bios and all. the problem is when configuring the raid setup, the promise controller only detect one HDD. all connector, cable and HDD work. what make me scared is that i found that on the asus web site about my motherboard:
RAID 0 supported by single Parallel ATA with single or dual Serial ATA connections,or dual Serial ATA connections alone.
RAID 1 supported by single Parallel ATA with single Serial ATA connection or dual Serial ATA connections alone.
so raid with dual P-ATA isn't possible and i have to change my HDD to the S-ATA version of it?
anyone got raid 0 working with 2 P-ATA drive?

thanks!

The answer lays actually in your question;
>RAID 0 supported by single Parallel ATA with single or dual Serial ATA connections,or dual Serial ATA connections alone

This means you need or a single ATA and a single SATA or both drives will be SATA.

You can purchase a new controller which will support both PATA drives but in my opinion, replace the drives both to SATA.

There were two ways you could initiate RAID. There use to be (as well as available now) boards that supports RAID via ATA (and the new ones may have both possibilities) or via SCSI controllers. Your abilities doing RAID through that kind of configuration is by design.

Below are two MB supports two methods of initiating RAID:
