[Plugin] Disk Viewer

Disk Viewer puts every disk on the server in one grid on the dashboard: array, cache, pools, boot device and unassigned drives, grouped by section. Each row shows spin state, filesystem, size, free, used with a bar, current read and write speed with direction, temperature and SMART health. It replaces the per-pool widgets Unraid ships, which stop being useful once you have more than a handful of disks.

What you get:

- A full table under Tools > Disk Viewer: everything from the widget plus lifetime writes, errors, age, reallocated and pending sectors, CRC errors, SATA link speed with a cable warning when a drive negotiates below what it supports, a verdict per disk, last and next scrub.

- Spin a disk up or down from its row, or a whole section from its header.

- Sleeping disks are never woken for a reading. A background task reads SMART only from disks that are already awake, so the table keeps showing a sleeping disk's counters. Temperature says sleep until it spins up.

- A badge in the WebGUI top bar with the worst current state across all disks: errors, temperature, SMART, usage. Visible from any page.

- Warning and critical colours for temperature and usage, taken from Unraid's own Display thresholds or set your own.

- Hide the disks you do not care about, pick columns, set the refresh interval, separately for the widget and the Tools page. Drag the widget footer to show more rows.

- Follows the Unraid theme (black, white, azure, gray) and works on the responsive 7.2+ WebGUI, phones included.

Requirements: Unraid 7.2.0 or newer for the dashboard tile; older versions get a plain fallback layout. The Unassigned Devices plugin is optional: unassigned drives are listed either way, their usage shows once they are mounted with it.

Install from Community Applications, search for Disk Viewer.

Support is on GitHub only. Bug reports, questions and requests go to GitHub Issues, not this thread. I do not follow forum threads for support, and a problem buried on page 14 of a thread helps nobody. One issue per problem, with the plugin version and your Unraid version, and I will answer there.

Two notes:

1. If you remember my earlier threads for this and the other plugins: I set them to hidden while I was fixing a few things, and a bug in the forum software made them disappear for good instead of hiding them. I could not get them back, so I am reposting them one at a time.

2. All my plugins are written with the help of AI. The design, the decisions, the testing on my own server and the responsibility for what ships are mine. I say it up front so nobody finds out later and feels misled.
