SMART Error Log Version: 1
ATA Error Count: 749 (device log contains only the most recent five errors)
CR = Command Register [HEX]
FR = Features Register [HEX]
SC = Sector Count Register [HEX]
SN = Sector Number Register [HEX]
CL = Cylinder Low Register [HEX]
CH = Cylinder High Register [HEX]
DH = Device/Head Register [HEX]

Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 749 occurred at disk power-on lifetime: 6972 hours (290 days + 12 hours)
When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were:

Haz el reemplazo si puedes.
Por otro lado, estos son 'solo' errores de lectura que no son tan malos. Si escribe en ese sector, solo puede estar seguro si tiene defectos.
Ejecutaría la utilidad de los proveedores para verificar (también realizan pruebas inteligentes) si tiene problemas. Por lo general, hacen disponibles los CD de arranque.
Puede y debe ejecutar una autocomprobación que puede hacer desde Linux emitiendo
Espere un par de horas (se mostrará una estimación). Luego verifique nuevamente con

Los errores de lectura pueden ser causados por algo tan simple como perder energía durante una operación de escritura. Solo, no sugieren ningún problema de hardware con la unidad.
