Show pretty HDD/SSD list

Show pretty HDD/SSD list

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

I had written "shd" shell script with a similar functionality. After I rewrote it in Python, added options and pretty colors. The current version 0.1 comes in Rust, as statically built binaries for x86_64 Linux, i686, ARM and AARCH64.

Installation

Install smartmontools (>=7.0), then download the appropriate binary from the releases page, chmod +x and enjoy.

Usage

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

  --temp-warn TEMP  Warning temperature, default: 40 C
  --temp-crit TEMP  Critical temperature, default: 45 C
  -f, --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

Exit codes

• 1 critical temperature
• 2 errors detected
• 3 smartctl error

The tool considers a drive has errors if its smart status is either not reported or reported as passed=false.

shd's Issues

Unable to get device /dev/nvme1 info

When invoking shd on my machine I get thrown the following error:

ewout@enthoo ~ % sudo shd -y
: /dev/nvme1Unable to get device /dev/nvme1 info: EOF while parsing a value at line 1 column 0
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: ()', src/main.rs:225:26
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

My machine uses the following disk layout:

/dev/sda property 'temperature' of 'Device' object has no setter

OS: Fedora 39

fix it by

            dev.temperature = c2f(dev.temperature, a.fh)
        except:
            pass

I know it's not a SATA SSD and the information you get from smartmontools have to be interpreted differently then, but maybe you could integrate that too?
