hard error

[′härd ′er·ər]
(computer science)
Any error that results from malfunctioning of hardware, including storage devices and data transmission equipment.

hard error

(1) A permanent, unrecoverable error such as a disk read error or circuit malfunction. Contrast with soft error.

(2) A category of errors that requires user intervention, including disk read errors, disk not ready (no disk in drive) and printer not ready (out of paper).

Integrated IBM-compatible cross parity error detection is combined with comprehensive error correction coding to produce a hard error rate of less than 1 in 10-to-the-13th power bytes of data.
These features produce an unequalled hard error rate specification of 1 error in 10 to the 17th bits-the best data specification for any tape drive available today.
Level-Six ECC for Data Integrity: An interleaved level-six RS-ECC (Reed-Solomon Error Correction Code) is used to achieve a hard error rate of less than 10 to the -15.
Second, the level-six Reed-Solomon error correction code (RS ECC) is used to deliver a hard error rate of less than one in 10 to the 15th power.
ECC (Error Correction Coding) protection against soft and hard errors on both DRAM and L2 Cache memories dramatically improves the Mean-Time-Between-Failures for enhanced reliability.
Most enterprises perform tape backup, and will most likely continue to do so in the foreseeable future because it plays an important role in data archiving for legal and other purposes such as data warehousing, transporting data to a new location, and/or as a second line of defense against hard errors in addition to methods of disk-based backup, mirroring, and/or replication.
It looks for soft and hard errors on the hard disk, notes where the error occurs and how significant the problem is, and takes corrective action if necessary.
With the FalconStor solution, customers can experience an enhanced application and data availability as well as storage management capabilities, providing our mutual customers with a backup, restore, and recovery regime that helps protect their data against soft and hard errors.
Durability is measured by the avoidance of hard errors to the tape media as sections of tape are cycled over the drive head for a set number of passes.
