exit code 121 - command smartctl

in flag

By using the command

sudo smartctl -t long /dev/sdb    

you can run a detailed test of the sdb drive. If I want to know during in the test how long it will last, you can use

sudo smartctl -c /dev/sdb | grep -A 1 "execution status".   

to get the "intermediate status". When I start the test of the sdb drive and then display the intermediate status, I always get the following message:

josef@antiphon:~$ sudo smartctl -c /dev/sdb | grep -A 1 "execution status" Self-test execution status: ( 121) The previous self-test completed having the read element of the test failed.    

Why is this? Should I worry about the disk?

Sry for my broken English.

You might get better information if you run `sudo smartctl -a /dev/sdb`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
