OWC Mercury Elite-AL Pro Qx2 Chapter 5 - Appendix
5.1 FAQ
Q: How do I format my storage solution?
A: OWC has detailed instructions online for most popular operating systems, located
at: http://www.macsales.com/format
Q: What le system should I choose when formatting my drive?
A: This will depend on how you want to use the drive, but in general, we recommend:
• Mac OS X - HFS + (Mac OS Extended)
• Windows 2000/XP/Vista
• For cross-platform compatibility, FAT32 is compatible, but single le sizes are limited
to 4GB. Other options using 3rd party software exist but are not covered here.
Q: Why does my solution not show up on my computer when using Windows 2000 /
XP?
A: Since Windows 2000 and XP 32 bit use Master Boot Record, the operating system
limits you to a maximum of 2TB . You need to set the switch on the back of the solution
to “B” to restrict the size to 2TB.
Q: How many drives can fail before I lose my data?
A: This depends on the RAID mode. For RAID 0 and SPAN, any drive failure will result
in the data being lost. For RAID 1, RAID 5, and RAID 10, the failure of two or more hard
drives at the same time will mean that data cannot be recovered.
Q: Will the hard drives spin down when my computer goes into to sleep or stand-by
mode?
A: Yes, they will spin down to save energy. It will take about 30 seconds to access your
data after being in sleep or stand-by mode.
Q: Why does the LED indicator for some of the drives light up red?
A: If one of the HDD LEDs lights up red and at the same time the Rebuild LED lights
up orange, the drive is defective. If less than 4 drives are installed and the Rebuild LED
does not light up at the same time, there is no drive installed in that bay.
5.2 About Data Backup
To ensure that your les are protected and to prevent the loss of your data, we strongly
suggest that you keep two copies of your data: One copy on your OWC Mercury Elite-
AL Pro Qx2 and a second copy on either your internal hard drive or another storage
medium, such as an optical backup, or on a second external hard drive. Any data loss
or corruption while using the OWC Mercury Elite-AL Pro Qx2 is the sole responsibility
of the user, and under no circumstances will Other World Computing be held liable for
compensation or the recovery of any lost data.
