read error

(computer science)
A condition in which the content of a storage device cannot be electronically identified.

read error

A failure to read the data on a storage or memory device. Although it is not a routine phenomenon, magnetic and optical recording surfaces can become contaminated with dust or dirt or be physically damaged, and cells in memory chips can malfunction.

When a read error occurs, the program will allow you to bypass it and move on to the next set of data, or it will end, depending on the operating system. However, if the damaged part of a disk contains control information, the rest of the file may be unreadable. In such cases, a recovery program must be used to retrieve the remaining data if there is no backup.

Infinite Warfare 's Sabotage DLC launched at the end of January with a slew of minor bugs and disc read errors. Hopefully those kinks will be worked out for the title's forthcoming additions.
On the diversity side, a major concern arises through the potential for NGS error rates to lead to an overestimation of diversity; that is, some of the variant sequences reported and used for calculation really just arise through PCR or sequence read errors. Increases in accuracy of NGS methods, as well as methodological approaches including incorporation of spiked control sequences monitored for "misread" rates, can help to minimize this source of error.
Overtime, dirt and dust can soil the laser lens of your CD-ROM drive, causing mistracking, signal skips and data read errors. Clean the lens with a CD-ROM drive lens cleaner, NSN 7045-01-450-4369 *.
Increase the speed and lifetime of data along with the most secure encryption on the planet, and the proprietary RAISE technology that virtually eliminates unrecoverable read errors makes the SuperNova the ideal choice.
Multi-level Phase Change Memory Breakthrough To achieve this breakthrough demonstration, IBM scientists in Zurich used advanced modulation coding techniques to mitigate the problem of short-term drift in multi-bit PCM, which causes the stored resistance levels to shift over time, which in turn creates read errors. Up to now, reliable retention of data has only been shown for single bit-per-cell PCM, whereas no such results on multi-bit PCM have been reported.
However changing parts of the chip into the amorphous phase creates a problem of continual resistance increases, called resistance drift, which eventual lead to read errors. To combat the problem, IBM developed an advanced modulation-coding technique, or software that can pick out and correct for drift-based errors.
If this split becomes excessive, read errors are induced.
It would take about 55 hours of continuous operation (assuming no read errors) to transfer the content of 50 DLT tapes containing 500 gigabytes of electronic records.
The higher the depth of read coverage, the better statistical strength this consensus sequence has, as correct reads at any individual position increasingly outnumber individual read errors.
For example, a tape written using a HP Ultrium drive was not readable or produced an unacceptable number of read errors when inserted in a Seagate drive.
