SATA RAID HD's

    Right... here's the story. Have a laptop, in the laptop is 2 x 80gig SATA HD's. Used a utility provided with the computer to create a striped raid array (RAID 0). After migration the program (Via RAID tool) told me to restart to allow my system to access the whole (160Gig) volume. After I restarted my second hard drive had indeed dissappeared form "my computer" but my C drive was still only 80Gigs. I've checked device manager and It says I've only got the one now although the VIA RAID tool assures me i have two, arrayed and both working normally.

    If I break the array I'll have to re-format. Is there any setting I need to change in Windows (XP home SP2 by the way) to allow it to "see" the second disk in the array? Laptop is a Fujitsu Siemens Amilo 3438g

    Any and all help appreciated.

    You have created a raid array which means 2 discs act as one in case of a disc dying.

    http://en.wikipedia.org/wiki/Redundant_array_of_independent_disks

    If thats what you want you have it both HDs will show as one and if one buggeres up you lose no data.


    Assume you wanted to make them faster using the "striped" option?

    Striping is normally for performance rather than reliability. Are you sure that there's not just ~80gb unpartitioned space on the array? Check in disk management.

    Thats if they're in a raid 1 setup... I have them in a raid 0 setup which basically joins them together. It makes the second drive a "barebones" 80gig slave for performance.

    @ stephen. I actually wasn't aware of the MMC utility. Disk manager shows it as unallocated space. Any easy way to fix that?

    yup, right click the "unallocated space" and you can partition, format and mount if from there.
