RAID Disk RecoveryWritten by Brad Triggs
RAID is short for Redundant Array of Independent (or Inexpensive) Disks, a category of disk drives that employ two or more drives in combination for fault tolerance and performance. RAID disk drives are used frequently on servers and increasingly being employed on personal computers. Array is operative word, which also dictates what cure is going to be, when a RAID disk recovery situation arises.RAID disk repair, as you may expect is quite a complicated process. But good thing going for it is chances for retrieving lost data is higher than with most other types of disks because typical RAID architecture strategically distributes data randomly across array. What this sort of architecture demands of recovery professionals is to specialize in disk’s many different levels. In a nutshell, these are all levels that RAID disk recovery team is up against. RAID 0, 1, 0+1; RAID 3, 4; RAID 5; RAID 10; Hardware RAID including: AMI, Compaq, Dell, Adaptec, IBM, etc.; and, Software RAID including Mac OS; Windows Servers including 2K, XP, NT; Linux, Solaris, Novell, etc.

Blu-ray is an optical disc format which is set to rival HD-DVD in race to be de-facto standard storage medium for HDTV. The HD-DVD vs Blu-ray battle resembles that between Betamax and VHS and DVD+RW and DVD-RW.Currently, major Hollywood film studios are split evenly in their support fro Blu-ray and HD-DVD, but most of electronics industry is currently in Blu-ray camp. The key difference between Blu-ray disc players and recorders and current optical disc technology is that Blu-ray, as its name suggests, uses a blue-violet laser to read and write data rather than a red one. Blue light has a shorter wavelength than red light, and according to Blu-ray Disc Association (BDA), which is made up of, amongst others, Sony, Philips, Panasonic, and Pioneer, this means that laser spot can be focussed with greater precision.
