According to the smartctl man page:
```
EXIT STATUS
The exit statuses of smartctl are defined by a bitmask. If all is well with the disk, the exit status (return value) of smartctl is 0 (all bits turned off). If a problem occurs, or an error, potential error, or fault is detected, then a non-zero status is
returned. In this case, the eight different bits in the exit status have the following meanings for ATA disks; some of these values may also be returned for SCSI disks.
Bit 0: Command line did not parse.
Bit 1: Device open failed, device did not return an IDENTIFY DEVICE structure, or device is in a low-power mode (see '-n' option above).
Bit 2: Some SMART or other ATA command to the disk failed, or there was a checksum error in a SMART data structure (see '-b' option above).
Bit 3: SMART status check returned "DISK FAILING".
Bit 4: We found prefail Attributes <= threshold.
Bit 5: SMART status check returned "DISK OK" but we found that some (usage or prefail) Attributes have been <= threshold at some time in the past.
Bit 6: The device error log contains records of errors.
Bit 7: The device self-test log contains records of errors. [ATA only] Failed self-tests outdated by a newer successful extended self-test are ignored.
```
BUG: 429028
Summary:
smartmontools 7.0 reports user capacity as an object that contains bytes and blocks value, instead of being an int that just contains bytes
This should fix incorrect calculation of bad blocks threshold and incorrect display of "Overall" status
Test Plan:
run partitionmanager on a system that has smartmontools 7, open smart status
overall status should be reported correctly
