The card's BIOS does not detect the hard drive(s) or RAID array(s) attached to the RAID controller.
What can I do to correct this problem?

Make sure the power and IDE cables are securely attached to the hard disks.
Check the drive(s) jumper settings, and make sure they correspond with the drive's configuration.

If drives are configured as master/slave (sharing a single cable), try setting each drive to cable-select.

If only one drive is attached to an IDE cable, set the drive to master. Some drives may require a single-master setting (or master with no slave present).
Check the drive documentation or contact the manufacturer for more information.

I cannot update the RAID controller built into my motherboard using the BIOS updates posted on your website.
What am I doing wrong?

The BIOS updates we provide only work for PCI card host adapters - they are not capable of updating HPT controllers that are integrated into motherboards.
You will need to search for the motherboard BIOS update that includes the required HPT BIOS. Visit the manufacturer's website for the proper downloads.

My motherboard's standard IDE controller cannot support large hard drives. Does the RAID controller support drives larger than 137GB?

Yes, our RAID controllers support hard drives larger than 137GB in size.
Make sure the appropriate BIOS and driver versions are installed for the RAID controller. Visit the motherboard manufacturer's website for the latest updates.

1.21 or better is required for the HPT374.
2.1 or better is required for the HPT370, 370A, and HPT372.
1.2 or better is required for the HPT371

I have no need for RAID at this time. Can the RAID controller support single drive configurations?

Yes - RAID is optional, not required. The RAID controller is capable of supporting RAID and non-RAID drive configurations.

Can the RAID controller support multiple arrays, or single disk and RAID configurations simultaneously?

Yes. The RAID controller can support multiple RAID arrays, as long as enough free channels are available.
The controller will also support single drives configured alongside a RAID array.

My array is reported as broken every time the system reboots - I am forced to recreate the array. What can I do to solve this problem?

Aside from a physical hard disk problem, the most common cause of array loss are loose power or IDE cables.
Make sure all cables connected to the drives and Rocket card are secure. Change cables if necessary.

A failing or under-powered power supply can also lead to this problem. If the drives do not power on and "spin" up correctly during bootup, the RAID controller may not detect one or more of the drives - this may result in a broken array.

Every time I boot my system, the RAID controller reports that the mirror (RAID 1) or 0+1 array needs to be synchronized, or duplicated.
(even after successfully repairing my array using the BIOS or RAID software). What can I do to solve this problem?

Make sure the driver, BIOS, and RAID software revisions (if installed) match. Mismatched revisions have been known to cause this problem, which may be a false alarm.

Windows does not detect the hard drive(s) or RAID array(s) attached to the RAID controller.
The RAID controller's BIOS does detect the drives. What can I do to correct this problem?

Make sure the drive or array has been partitioned and formatted. Non-partitioned hard disks or RAID arrays are not assigned drive letters, and cannot be accessed or used by the operating system.
If you are using running a Win 9x system (95, 98 or ME), you can partition the drive or array using the FDISK utility.
If you are running NT, Win2k or XP, you can partition the drive or array using the Disk Management utility.
