ARAID Questions & Answers PC BIOS setup
Q: What type of hard drive should be selected in the PC BIOS setup?
A: If you are using two identical hard drives (same manufacturer and model) in your ARAID,
select HDD TYPE of AUTO.
If you replace a failed hard drive with a new disk with the same brand, and the same model
series, but with a larger capacity, select HDD TYPE: AUTO, as well.
If the replacement drive is larger than the surviving drive, it is imperative that you place the
smaller (surviving) drive in the upper bay, then boot the computer. When the operating system
is booted, insert the new larger capacity disk in lower bay and launch auto rebuild.
Power failure while disk rebuild is in progress
Q: What should I do if the power fails while auto-rebuild is in progress?
A: Just turn on the PC again, the disk rebuild will restart and continue, regardless of whether
you are rebuilding from primary to secondary (upper bay to lower bay) or rebuilding from
secondary. To primary (lower bay to upper bay).
The PC will boot from the source disk, whether it is primary or secondary, then it will
automatically resume the disk rebuild sequence without further user intervention.
Preventing and recovering from an unexpected virus attack
Q: How can I prevent or recover from a virus attack by utilizing Mirror-On-Demand function
provided by ARAID? (for RAID 1 users only).
A: Prevention is the most important factor in preventing a virus attack. Accordance
recommends the use of commercial grade anti-virus software and a hardware firewall.
Remember to check with the AV and firewall manufacturer’s website frequently for the latest
updates to their products.
If you find that you are infected, run the AV software first to clean or quarantine the virus.
Here are some other recommendations you can optionally use.
Method 1: Generate a grandfather/father/son, multi-generation backup Use the ARAID
on-the-fly disk rebuild and disk hot swap function to duplicate a clone
periodically as you require. Keep the archive of your generated backup disks
in safe place. If both disks in an ARAID array are affected by a virus, remove
them and replace with the latest unaffected archive disk and rebuild a clean
disk array in just minutes.
Method 2: Use Accordance the mirror-on-demand function on the front panel operation
mode switch to initiate a disk duplication whenever you need. While the
system is clean and virus-free, make sure to generate clone disks and keep
them in safe place.
