5. Frequently Asked Questions (FAQ)
Q:
What are HPA and DCO?
A:
A Host Protected Area (HPA) and Device Configuration Overlay (DCO) are reserved areas on a hard
drive that are not accessible by the BIOS or OS. Data can be hidden behind an HPA or DCO.
WiebeTech forensic devices will alert you if there is an HPA or DCO so that you are aware of it and can
take the necessary steps to retrieve the hidden data.
Q:
Why does my eSATA device appear as a Parallel SCSI device in System Profiler?
A:
The "Serial ATA" tab in System Profile shows devices attached to the internal SATA bus, but not
always devices attached to an eSATA host card. Sometimes these devices will appear under the heading
"Parallel SCSI" instead. This is entirely normal and does not indicate a problem with the device or its
drivers.
Q:
Why is it necessary to update the firmware of my WiebeTech forensic device?
A:
Firmware relates to the programs and data that control electronic products. Firmware is enhanced
over time, usually to add new features or increase compatibility. Updating firmware can improve the
functionality and dependability of your product. If your WiebeTech forensic device is using outdated
firmware, the WiebeTech Forensic Software Utility can recognize this and implement up-to-date firmware
on your device. See section 3.2 of this manual for more info.
Q:
My Forensic LabDock works great with SATA drives but I am having compatibility issues with
IDE/PATA drives. What should I do?
A:
First check to make sure the SATA power/data cable is unplugged from the SATA output port.
IDE/PATA drives cannot be recognized if a SATA connection is made with the SATA output. Next check
to make sure the 4-pin power cable is plugged into the IDE/PATA drive. If the power and host connection
are securely attached to the UltraDock, then the IDE cable may be faulty. Contact Technical Support for
further instructions.
Q:
How should I set my hard drive jumper settings?
A:
Note: This is only necessary for IDE/PATA drives (the type of drive that has a 40-pin data interface).
Try the MASTER setting first. This is the recommended setting for most WiebeTech products. Some hard
drives have two different MASTER settings: one for when there is a SLAVE drive present and one for
when there is NO SLAVE drive present. Choose the setting for NO SLAVE present. There may be some
drives that will not work with either of these settings. The next choice is CABLE SELECT. If this does not
work, try using NO jumpers. This may be the same as MASTER with NO SLAVE present.
If you're unsure how to change the jumper configuration, check the manual that came with your hard
drive, or the manufacturer's website. Some drives also have the information printed on the label.
