Seagate Diagnostic Commands 

seagate-logo

Upon power up, the drive will respond to a set of diagnostic command send through serial port. Because of the number of commands supported, the commands are broken up into ‘Levels’. Many, the progress may be sent over the serial port for number of bits written and read, and command such as read, write, seek, and error log manipulation are available at several different levels. Diagnostic commands are used in place of ATI scripts to do testing. While the drive is running these diagnostic commandshard/soft error rates, a number indicating the test currently being performed, and various information for status of the current test. 
The firmware consists of 2 flash codes and numerous supporting files. The two flash codes are known as factory code and customer code. The factory code contains all the serial port diagnostics command but no AT interface command. The customer code contains all AT interface command but minimal set of serial port diagnostics command. 
In the ‘Availability’ column, a ‘F’, ‘C’ and ‘B’ indicate the command is available at ‘Factory Code’, ‘Customer Code’ and ‘Both codes’ respectively. 
The following is a short list of some of the serial port commands: 
Level T – Certification Tests. 
Download code 
Start manufacturing test 
Set drive ‘Age’ 
Commands to read cert logs, read error logs, write test data to flash, etc. 
Level 1 – Memory Control Commands. 
Commands to display buffer, display memory, set memory, copy buffer to flash, read 
sysvars from disk, etc. 
Level 2 – Drive Level Commands 
A command to configure the cylinders, heads for testing, gives option for random 
cylinder/head and random data patterns 
Commands to set data patterns, perform ECC tests, manipulate the error log, dump the 
sequencer ram. 
Commands to do physical to logical conversion, assign skips and alternates, etc. 
Commands to spinup, spindown, seek, read, write, read long, write long, read compare, 
sleep, set retries, etc. 
Level 3 – Seeking Commands

- Set actuator bias current 

Level 9 – Drive Level Command (Full-slipping Defect Management Mode) 
Beside the above nine levels of commands, there are two additional sets of commands, the On-line commands and Common commands. The main purpose of On-line command is to display varies type of status. Common command is use to ‘poke’ and ‘peek’ into memoery to allow access to registers, buffer memory and data memory. 
2.1 ON-LINE COMMANDS 
The On-Line commands may be initiated at any time. For the Interface-specific commands, the Interface code must be present in the current memory map for successful execution; the General commands are always available.

ASW WORD 
The Algorithm Selector Word (ASW) is a command to tell the flash upgrade routine to select the correct flash programming algorithm. It can be issued as a parameter in the SDLE.EXE software. The idea is to have single generic routine to cater for different flash memory programming algorithm. Typical flash programming involves ‘word programming’ and ‘sector programming’. If a new flash vendor is cut in, the firmware is not required to change. Just use the correct ASW will do.

Gran capacidad masiva – Los discos duros SATA Caviar Green de WD entregan hasta 3 TB de almacenamiento en un único disco.
WD satisface los desafíos tecnológicos de la implementación de discos duros SATA de 3 TB – Un solo disco duro SATA ahora puede almacenar hasta 3 TB de datos. WD está liderando el sector, proporcionando soluciones para la implementación de discos de 2,19 TB y mayores.

WESTERN-DIGITAL-ONRETRIEVALOnRetrieval-Tecnico-camara-limpia

Consumo de energía reducido – WD ha reducido el consumo de energía para ayudar a que los clientes conscientes de la importancia del ahorro de energía construyan sistemas con mayor capacidad y consigan el perfecto equilibrio entre el rendimiento del sistema, la fiabilidad garantizada y el ahorro de energía.
Frío y silencioso – Los discos con WD GreenPower Technology producen temperaturas operativas más bajas para coseguir una mayor fiabilidad y un nivel de ruido muy reducido para ordenadores y discos externos ultrasilenciosos.
Perfecto para discos externos – Los fabricantes de discos externos pueden eliminar la necesidad de incluir un ventilador en sus productos de gran capacidad si lo reemplazan por los discos duros WD Caviar Green silenciosos y de operación en frío.
IntelliPower – Un equilibrio adecuado entre velocidad de rotación, velocidad de transferencia y algoritmos de caché diseñado para contribuir al ahorro de energía y proporcionar un rendimiento uniforme. Adicionalmente, los discos WD Caviar Green consumen menos energía durante el arranque, lo que permite que las cargas de los sistemas sean menores en el momento de arrancar.
IntelliSeek -  Calcula las velocidades de búsqueda óptimas para reducir el consumo de energía, el ruido y las vibraciones.
Tecnología NoTouch con rampa para carga del cabezal – El cabezal de grabación nunca toca la superficie del disco, lo cual genera un desgaste significativamente menor del cabezal de grabación y del soporte, además de una mejor protección del disco cuando se transporta.
Formato avanzado – La tecnología que WD y otros fabricantes están adoptando es una de las muchas maneras en que continuamos aumentando la capacidad de nuestros discos duros. El formato avanzado (AF) es un formato multimedia eficiente que permite el aumento de densidades de área. (Sólo modelos RS y RSDTL)

Ideal para:

PC de sobremesa y almacenamiento externo que requieren un menor consumo de energía y un funcionamiento frío y silencioso.

Si tienes un problema con tu disco duro, si se te ha caido al suelo es muy probable que se halla roto alguna pieza mecanica (bloques de cabezas) o el eje de los platos este bloqueando el movimieto de los mismos.

OnRetrieval “empresa de recuperacion de datos” te recomienda que no lo enciendas mas, ya que podrias estar poniendo tu informacion en peligro, las cabezas al recibir un impacto se rompen y pueden rayar los platos, esta accion hace que la informacion se perderia o se corrompa.
