# poormon
not SMART front end to smartctl(smartmontools)
- only show attributes 5, 187, 188, 197, 198 that picked from [Backblaze blog](https://www.backblaze.com/blog/what-smart-stats-indicate-hard-drive-failures/)
- show `devstat` if available
- show DWPD (Drive Write Per Day)
# examples
#### TOSHIBA Consumer Grade HDD
need `root` user or `disk` group
```
$ sudo ./poormon /dev/sdf
Device: TOSHIBA DT01ACA300 (~~)
Capacity: 2794.52 GiB (3000.59 GB)
Power On: 0.17 years (1504 hours, 62.7 days, power cycle 154)
SMART:
5: Reallocated Sectors Count : 0
197: Current Pending Sector Count : 0
198: Uncorrectable Sector Count : 0
Device stat:
Write: 7.94 TiB (2.91 drive write)
Read: 9.37 TiB
Read/Write Ratio: 1.18
Write per Year: 46.24 TiB/year
Write per Day: 129.72 GiB/day (0.046 DWPD)
Read per Year: 54.58 TiB/year
Read per Day: 153.11 GiB/day
Read Recovery: 0 corrected, 0 uncorrect
Interface CRC Errors: 0
Mechanical Start Failures: 6
```
this consumer grade drive support devstat(cool!).
but another one is ...
#### Seagate Consumer Grade HDD
```
Device: ST2000DL003-9VT166 (~~)
Capacity: 1863.02 GiB (2000.40 GB)
Power On: 2.25 years (19737 hours, 822.4 days, power cycle 2376)
SMART:
5: Reallocated Sectors Count : 0
187: Reported Uncorrectable Errors : 0
188: Command Timeout : 2
197: Current Pending Sector Count : 0
198: Uncorrectable Sector Count : 0
Device stat: not supported
```
this one isn't.
and `Command Timeout: 2`, I need to watch out.
#### TOSHIBA Consumer Grade SSD
```
Device: TOSHIBA THNSNJ256GCSU (~~)
Capacity: 238.47 GiB (256.06 GB)
Power On: 0.41 years (3597 hours, 149.9 days, power cycle 406)
SMART:
5: Reallocated Sectors Count : 0
197: Current Pending Sector Count : 0
Device stat:
Write: 1669.96 GiB (7.00 drive write)
Read: 1103.65 GiB
Read/Write Ratio: 0.66
Write per Year: 3.97 TiB/year
Write per Day: 11.14 GiB/day (0.047 DWPD)
Read per Year: 2.62 TiB/year
Read per Day: 7.36 GiB/day
Endurance Indicator: 1% used
Interface CRC Errors: 0
```
many of modern SSD supports `Endurance Indicator`.
T13 explain
> percentage of device life used based on the actual device usage and the manufacturer's prediction of device life.
#### HGST Enterprise Grade HDD (old)
```

SMART:
5: Reallocated Sectors Count : 0
197: Current Pending Sector Count : 0
198: Uncorrectable Sector Count : 0
Device stat:
Write: 7.06 TiB (7.76 drive write)
Read: 212.98 TiB
Read/Write Ratio: 30.15
Write per Year: 1.89 TiB/year
Write per Day: 5.31 GiB/day (0.006 DWPD)

Interface CRC Errors: 0
Mechanical Start Failures: 4294967295
```
this just about $25 at junk shop.
over 30000 hours, but still operational.
I need to be careful because of Mechanical-something looks wrong.
## TODO
- temperature stuff?
