Appendix D Solid-state Drive
Installation Use caution when installing or handling a solid-state drive. You must handle the
drive with care to prevent possible electrostatic discharge (ESD) damage.
Follow these guidelines when installing or handling a solid-state drive:
• Ground yourself whenever possible before handling the solid-state drive.
• Handle the drive by its case.
• Leave the product in a protective ESD bag until the time of installation.
• Align the CompactFlash card properly during installation to make sure the
pins do not bend.
• Install the screw to hold the CompactFlash card in the slot.
Operation The solid-state drive appears to the system host as a standard rotating hard disk
drive when powered up. The system host identifies the solid-state drive during
bootup and sets the IDE bus speed to reflect the capability of the drive.
Do not remove power abruptly. Always use the proper power down procedure as
required by your operating system, such as the Shut Down function in the Start
menu. Whenever possible, use an uninterruptible power source (UPS) or other
power conditioning device to perform a proper shutdown during unexpected
power interruptions.
The controller on the solid-state drive uses an error correcting code (ECC) and
cyclic redundancy check (CRC) to check for data errors.
Data correction algorithms can prevent data corruption on the drive. However,
they cannot prevent operating system (OS) file type errors when the OS breaks
large files into smaller (multiple) file transfers. This results in the host receiving
only part of the transfer.
IMPORTANT Always protect your system against unexpected power interruptions.
