1 Raw_Read_Error_Rate PO-R-- 062 062 062 NOW 572391424
You also have 3 logged crc errors with the sector number given (
ABRT at LBA = 0x6e44b467 = 1849996391), but perhaps they all occurred at the same time due to mechanical or electrical disturbance, and may not be associated with the failure.
The read error rate however suggests that many blocks are having to be read several times by this drive until it gets a good crc that means the data was read ok.
What you can do is run a short or long non-destructive selftest that will try to read each cylinder or sector and provide statistics on how successful it was. Do
smartctl -t short /dev/sda or
smartctl -t long /dev/sda and it will say something like
Please wait 180 seconds for test to complete. After this time, redo the
smartctl -a to see the result and any new information it provides.
