smartmontools has more features and also understands rare setups with e.g. RAID controllers, early USB enclosures or vendor-specific (usually undocumented) parameters. It also comes with smartd to monitor drives continously. For plain SATA drives atactl is fine. It can also pass SMART commands to most USB drives that attach as sdX.
I was lucky - in my case, atactl is apparently sufficient for the basics. Not so lucky, but also no surprise, is the result of the self-test:
```
saturn$ doas atactl wd2 smart selftest-log
SMART supported, SMART enabled
Log entry: 21
Name: Off-line
Status: No error
Log entry: 0
Name: Short off-line
Status: Read element of test failed
LBA first error: 1375756400
saturn$
```
I will overwrite the disk with zeros once as a test. According to the
S.M.A.R.T. values, the number of "pending" sectors has already decreased
- from 18 to 15.
``` 197 200 0 no online positive Current pending sector 15 ``` Kind regards Matthias
