Raid 1 Data Recovery
1. Raid 1 Data Recovery FAQ
Q: What is the definition of a “RAID 1″ volume?
A: “RAID 1″ refers to a “Redundant Array of Inexpensive (or Independent) Disks” that have been established in a Level 1, or mirrored, drive set. A RAID 1 volume is a set of disk drives that are configured for data to be written to 2 volumes simultaneously. This configuration provides complete data redundancy in the event of a drive failure.
Q: What is meant by the term “mirroring”?
A: Within a mirroring (RAID 1) volume, the exact same information that is written to one disk is also written to a second disk, creating a “mirror image”, or clone, of the orginal hard drive.
Q:…
Hard drives are usually nearly silent but some do make a muted clicking sound when they’re being accessed – this is normal. On the other hand, if you start hearing noises only occasionally or noises that you’ve never heard before – like clicking, grinding or squealing – your hard drive may be failing.
Hitachi Drive Fitness Test is free hard drive diagnostic software available for use on most drives available today.
