Thread: RAID 1 on SATA 1.5Gb with SATA II HDs

    Default RAID 1 on SATA 1.5Gb with SATA II HDs

    I have just bought a new comp and wanted to create a second array with a Adaptec 1210SA SATA1 Raid card and two SATAII WD 250GB hard drives. When i create the array there are no issues, until i restart, boot to Win (XP), one of the hard drive fails and degrades the array.
    My question is:
    is it possible to have SATAII drive on SATA1 raid controller ?

    Is there a way to "dumb" down the drives, or is that done automatically ?

    The HDs works normally as JBOD or singles, they fail only when inside the array.

    Any hint would help, thanks.

    1- Yes, you should be able to use SATA2 drives on a SATA1 controller. The technology was purposely created to be backward compatible.

    2- It is often done automatically, but I have heard of some folks who had to move a jumper or change a BIOS setting. Check out the documentation for your controller and see if you might need to change something to make it work properly.

    great. I was hoping they were compatible. Afterall it was all possible with old ATA100xATA66, etc.

    I just want to make sure i dont return the drive because it might be faulty if the issue is a setting somewhere. I will definitelly check the settings, perhaps flash the firmware etc...

    thanks !
