Drive Issues

Q:Can I add a drive to a SuperTrak66 RAID array via hot-swap and dynamically adjust the array size/configuration?

A:No. The SuperTrak66 system does not support dynamically adjustable RAID size/configurations.

Q:Can I take a set of drives which make up an array created on one SuperTrak66 server and move it to another SuperTrak66 server?

A:Yes. All SuperTrak66 servers read the arrays the same way. Once the drives are all connected, you must restart the system for it to recognize the newly- inserted array configuration.

Q:Can I take a drive used in a SuperTrak66 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 1), single drive striped (RAID 0), or single drive spanned array. Multiple drives striped or spanned will not work. Also, the other controller must address the drives as LBA, not CHS.

Q:If I have a problem with one of the drives on the SuperTrak66, 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 which 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 SuperTrak66 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! The purpose of disk management software is to provide support for hard drives larger then 504MB to those systems which have no intrinsic support. Since the SuperTrak66 provides all the large disk support you need to access your array(s), this software is unnecessary, and in some cases may even cause accessibility problems.

Q:What system BIOS CMOS settings do I use for the drives on the SuperTrak66 controller?

A:None. The drives on the SuperTrak66 controller are supported by the SuperTr ak BIOS and/or O/S drivers, not by your system BIOS.
