Drive Issues

Q:
Can I add a drive to a FastTrak100 RAID array via hot-swap and
dynamically adjust the array size/configuration?
A:
No. The FastTrak100 system does not support dynamically adjustable RAID
size/configurations.
Q:
Do the HDDs on the FastTrak100 have to be the same siz e?
A:
The HDDs that you use with the FastTrak100 do not have to be the same size. If
the sizes differ, the FastTrak100 will "adjust" the HDDs so that they are
compatible. Basically, it will truncate the bigger HDD so the sizes match. Any
unused space that results from this is unusable, so don't use HDDs that differ
too much. It'll work, but it's a waste.
Q:
I already have an array on an older FastTrak controller. Can I move that
array to my new FastTrak100 TX/LP series controller?
A:
Yes. All FastTrak controllers read the arrays the same way and can be moved
from controller to controller.
Q:
Can I take a drive used in a FastTrak100 array and access it directly
with a different controller, such as the one integrated on the
motherboard?
A:
Yes, but only under certain configurations. The following array configurations
will allow the drive(s) to be accessed individually on another controller: mirror
(RAID 0), single drive striped (RAID 1), or single drive spanned (JBOD). Multiple
drives striped or spanned will not work. Also, the controller must address the
drives as LBA, not CHS.
Q:
If I have a problem with one of the drives on the FastTrak100, how can I
low level format it to correct the problem?
A:
Do NOT do this. Low -level formatting IDE drives is unnecessary and generally
does not correct problems that might be experienced during use. Errors such as
bad sectors or ECC/CRC failure are best remedied by completely replacing the
drive. For this reason, drives attached to the FastTrak100 controller should NOT
be low level formatted.
Q:
Do I have to install disk management software on my array in order to
access the full storage capacity of drives?
A:
No! Disk management software would only complicate things. The array should
be fully addressable by your O/S as it is. Remember that some operating
systems have varying limits on the sizes of partitions and logical drives that can
be defined. Consult your O/S documentation about partitioning larger drives.
Q:
What system BIOS CMOS settings do I use for the drives on the
FastTrak100 controller?
