Show pretty HDD/SSD list

Long time ago when I've switched from Solaris to Linux, I missed "hd" utility. In Linux "hd" command is used for a hex dump, in Solaris it displayed a pretty table with HDD info.

I wrote "shd" shell script with a similar functionality. Now I rewrote it in Python, added options and pretty colors, and releasing it to public.

Installation

Install smartmontools, then:

python3 -m pip install shd

Usage

Tool should be started under root, to obtain S.M.A.R.T. info

shd [-h] [--temp-warn TEMP] [--temp-crit TEMP] [-R] [-y] [-e] [-s] [-J]

  --temp-warn TEMP  Warning temperature, default: 40 C
  --temp-crit TEMP  Critical temperature, default: 45 C
  --fh, --fahrenheit  Temperature in Fahrenheit
  -R, --raw         Suppress colors
  -y, --full        Display full disk info
  -e, --errors      Display only disks with errors / critical temperature
  -s, --no-header   Suppress header
  -J, --json        Output as JSON

Exit codes

• 1 critical temperature
• 2 errors detected

The tool considers drive has an errors, if the following S.M.A.R.T. fields are greater than zero:

• End-to-End_Error
• Seek_Error_Rate
• Raw_Read_Error_Rate
• UDMA_CRC_Error_Count
