SMART Error Log Version: 1
Number of ATA errors: 100 (the device log contains only the five most recent errors)
CR = order register [HEX]
        FR = Feature Registration [HEX]
        SC = sector count register [HEX]

Powered_Up_Time is measured upon power up and printed as follows:
DDd + hh: mm: SS.sss where DD = days, hh = hours, mm = minutes,
SS = s and sss = millisec. It "wraps" after 49,710 days.

Error 100 during the lifetime of the disk: 43262 hours (1802 days + 14 hours)

Selective self-test indicators (0x0):
After analyzing the selected tracks, DO NOT read / analyze the rest of the disc.
If the Selective Self Test is waiting at power up, resume it after a 0 minute delay.

This is the first time I receive this email and I am seeing problems. The other disk sda seems to be good.
