Description
The spinning drive is connected to QNAP TR-002.
Using the flag -x causes the data read/write transmission to freeze temporarily while the smart test is being performed, then just keeps running normally:
# time smartctl -x -d sat /dev/sdc | grep -i temperature 194 Temperature_Celsius -O---K 100 100 000 - 35 (Min/Max 14/52) real 1m1.655s user 0m0.041s sys 0m0.004s
dmesg complains about it every time the command is run:
[ 1462.569558] usb 2-5: reset SuperSpeed USB device number 3 using xhci_hcd
Using the -a flag does not cause that issue and is much faster:
# time smartctl -a -d sat /dev/sdc | grep -i temperature 194 Temperature_Celsius 0x0022 100 100 000 Old_age Always - 38 (Min/Max 14/52) real 0m0.113s user 0m0.026s sys 0m0.005s
Connecting the drive to StarTech.com SDOCKU33EF is much faster and does not raise any dmesg log even with -x flag:
# time smartctl -x -d sat /dev/sdc | grep -i temperature 194 Temperature_Celsius -O---K 100 100 000 - 40 (Min/Max 14/52) Current Temperature: 40 Celsius Power Cycle Min/Max Temperature: 35/40 Celsius Lifetime Min/Max Temperature: 14/52 Celsius Specified Max Operating Temperature: 55 Celsius Under/Over Temperature Limit Count: 0/0 SCT Temperature History Version: 2 Temperature Sampling Period: 1 minute Temperature Logging Interval: 1 minute Min/Max recommended Temperature: 5/55 Celsius Min/Max Temperature Limit: -40/70 Celsius Temperature History Size (Index): 478 (107) Index Estimated Time Temperature Celsius 0x05 ===== = = === == Temperature Statistics (rev 1) == 0x05 0x008 1 40 --- Current Temperature 0x05 0x010 1 36 N-- Average Short Term Temperature 0x05 0x018 1 - N-- Average Long Term Temperature 0x05 0x020 1 52 --- Highest Temperature 0x05 0x028 1 14 --- Lowest Temperature 0x05 0x030 1 46 N-- Highest Average Short Term Temperature 0x05 0x038 1 34 N-- Lowest Average Short Term Temperature 0x05 0x040 1 - N-- Highest Average Long Term Temperature 0x05 0x048 1 - N-- Lowest Average Long Term Temperature 0x05 0x050 4 0 --- Time in Over-Temperature 0x05 0x058 1 55 --- Specified Maximum Operating Temperature 0x05 0x060 4 0 --- Time in Under-Temperature 0x05 0x068 1 5 --- Specified Minimum Operating Temperature real 0m1.323s user 0m0.061s sys 0m0.004s

Happens also on Ubuntu 24.04 with kernel 6.8.0-45-generic x86_64:
time smartctl -x -d sat /dev/sdc | grep -i temperature 194 Temperature_Celsius -O---K 100 100 000 - 33 (Min/Max 14/52) real 1m1,728s user 0m0,033s sys 0m0,009s

-x is the same as:
-H -i -g all -g wcreorder -c -A -f brief -l xerror,error -l xselftest,selftest -l selective -l directory -l scttemp -l scterc -l devstat -l defects -l sataphy
Please try which of the options trigger the problem. The usual suspects are the commands using SCT protocol which requires WRITE SMART LOG: -g wcreorder -l scttemp -l scterc.

I've found that it's not even necessary to have any file transfer, the command just locks the terminal until the operation is performed, and can't be cancelled with control+c.
The culprit is only -l devstat:
