RPi 4 - hdparm let system crash

[bismosa]

Hello!

I am using a Raspberry 4 (2 + 4GB RAM) with Libreelec 9.2.1
(Linux Video 4.19.106 #1 SMP Tue Mar 3 15:40:36 EST 2020 armv7l GNU/Linux)

I have a script running to monitor the system status. There is a line:

Code: Select all

hdparm -C /dev/sda

to get the status active/ide/standby from the HDD.

Every few hours the system crashes. First the HDD is not responsible and some time later the rpi doesn't response.

In dmesg i have the folowing output:

Code: Select all

If i than try to read Data from the Drive i get

Code: Select all

[18066.724135] print_req_error: I/O error, dev sda, sector 976770944

What can i do to avoid this problems?
