Repeating the same questions is an excellent method of achieving quality.  It is called "auditing".  You audit the organization's ability to follow the defined processes.

If your computer keeps doing consistency checks, your hard drive may be going bad.  Have a technician check it out.  If the hard drive dies you run the risk of losing all of your information.

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 but aren't generally necessary for personal computers.\n\nThere are number of different RAID levels:\n# Level 0 -- Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple disk drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.\n# Level 1 -- Mirroring and Duplexing: Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.\n# Level 2 -- Error-Correcting Coding: Not a typical implementation and rarely used, Level 2 stripes data at the bit level rather than the block level.\n# Level 3 -- Bit-Interleaved Parity: Provides byte-level striping with a dedicated parity disk. Level 3, which cannot service simultaneous multiple requests, also is rarely used.\n# Level 4 -- Dedicated Parity Drive: A commonly used implementation of RAID, Level 4 provides block-level striping (like Level 0) with a parity disk. If a data disk fails, the parity data is used to create a replacement disk. A disadvantage to Level 4 is that the parity disk can create write bottlenecks.\n# Level 5 -- Block Interleaved Distributed Parity: Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of RAID.\n# Level 6 -- Independent Data Disks with Double Parity: Provides block-level striping with parity data distributed across all disks.\n# Level 0+1 – A Mirror of Stripes: Not one of the original RAID levels, two RAID 0 stripes are created, and a RAID 1 mirror is created over them. Used for both replicating and sharing data among disks.\n# Level 10 – A Stripe of Mirrors: Not one of the original RAID levels, multiple RAID 1 mirrors are created, and a RAID 0 stripe is created over these.\n# Level 7: A trademark of Storage Computer Corporation that adds caching to Levels 3 or 4.\n# RAID S: EMC Corporation's proprietary striped parity RAID system used in its Symmetrix storage systems.

Round Robin testing is done to ensure that different testing labs report similar results. The variations are sometimes used to certify labs, equipment and technicians. Similar results from various labs show that test methods are correctly applied at each location.

Redundancy in engineering is the duplication of critical components of a system with the intention of increasing reliability of the system, usually in the case of a backup or fail-safe.\n\nOr it is a system design that duplicates components to provide alternatives in case one component fails\nconfiguration, constellation - an arrangement of parts or elements; "the outcome depends on the configuration of influences at the time"\n\nIn many safety-critical systems, such as fly-by-wire aircraft, some parts of the control system may be triplicated. An error in one component may then be out-voted by the other two. In a triply redundant system, the system has three sub components, all three of which must fail before the system fails. Since each one rarely fails, and the sub components are expected to fail independently, the probability of all three failing is calculated to be extremely small. Redundancy may also be known by the terms "Majority voting systems" or "voting logic".

A general rule of thumb I have heard in engineering is "the fewer moving parts the more reliable" (another conflicting rule is "if it ain't broke, it doesn't have enough features yet").\n\nI would say it depends on the application.  I know hard-drives inside computers or MP3 players are very sensitive mechanical components.  Then again, electrical hardware is prone to overheating.

here you go...\n(it'll work with up to 255 different disks, if you need more, you'll have to replace chars with ints)\n\nm1(char *a,b) {memove(b+1,b,strlen(b)+1); *b=*a; memmove(a+1,a, strlen(a);}\nm(char *a,b,c) {if (*a)  {m(a+1,b,c);m1(a,c);m(b,c,a);}

A residual current device (RCD), or residual current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the flow of current is not balanced between the phase ("hot") conductor and the neutral conductor. The presumption is that such an imbalance may represent current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A shock, possibly lethal, is likely to result from these conditions; RCDs are designed to disconnect quickly enough to prevent such shocks.
