RAID config with simple volumes

[Guest]

I am attempting to do a software raid partition on my two SATA drives. I
converted them to dynamic drives, howevre they both appearred as simple
volumes (one drive has an 8Mb unallocated sector???) and won't allow me to
partition them or create a striped raid volume. Is there any way to fix this
so I can create a RAID 0 area across about half of both drives?

Thanks
Glen

Is your (does your) BIOS set for this?

You need to have unallocated space on both drives. With two drives you can
make a striped volume double the size of the smallest unallocated space. If
one of the drives is your system volume created during the install you will
not be able to resize it with the built in tools. You will need 3rd pary
software. If you are trying to increase performance software RAID is not the
way to go. Also RAID 0 is not fault tolerant. If one of the drives fail you
lose all the data on the striped volume. Striped volumes are normally set up
with SCSI bus mastering controllers in servers where backups of data are
done regularly and there are multiple redundant servers. They are used for
swap files and high performance databases with 1,000's of accesses at a
time. IDE drives even SATA have too much overhead to use this method to
increase performance by a noticable amount. A lot of the time performance is
decreased.
