WD80EFAX-68LHPN0 drive permanently shows ATA Error

[TuxoHolic]

This disk suddenly got a permanent error entry:
199 UDMA_CRC_Error_Count 0x000a 200 200 000 Old_age Always - 1

SMART Error Log Version: 1
ATA Error Count: 1
Error 1 occurred at disk power-on lifetime: 1051 hours (43 days + 19 hours)

When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were:
ER ST SC SN CL CH DH
-- -- -- -- -- -- --
84 41 00 00 00 00 00 Error: ICRC, ABRT at LBA = 0x00000000 = 0

Commands leading to the command that caused the error were:
CR FR SC SN CL CH DH DC Powered_Up_Time Command/Feature_Name
-- -- -- -- -- -- -- -- ---------------- --------------------

It looks like a single data transmission (CRC) error bewtween disk and SATA controller.

Is it correct to assume that this does not really influence the probability of future errors?

Unfortunately running smartctl -ad sat /dev/sdb returns error status 0x4000 wich I could not find in the documentation. Could you please give a hint to documentation of high valued exist status.
Many thanks!

Please provide the output of smartctl -d sat -a -x /dev/sdb as an attachment(!) to this ticket. Add -q noserial if desired. Do not discard the very first output line as it contains important information about smartctl version and platform.

Such a single CRC error is usually harmless. But this error log may be incomplete because it is the legacy error log (-l error) which only supports 28-bit LBA. Also check the extended error log (-l xerror, included in -x but not in -a) instead.

Smartctl exits with 0x40 if the legacy error log is non-empty. This is usually returned as 0x4000 by POSIX functions like pclose() and waitpid() and should be converted back with WEXITSTATUS().

smartctl -d sat -a -x

Drive reports single CRC error in both error logs. Smartctl behaves as expected.
