Govibe Disk Power Management 1.8.1

A safe Ubuntu/Linux GUI to manage secondary disk power.

Features:
- Lists detected disks and protects system drives.
- Unmounts selected non system partitions.
- Sleeps HDDs with hdparm standby.
- Hard powers off selected drives with udisksctl.
- Saves hard powered-off drives as a persistent policy.
- When the app starts at login after reboot, saved drives are automatically unmounted and powered off again.
- Start on login support.
- Limited administrator helper with sudoers NOPASSWD for disk actions only.
- Real C ATA power probe for status lights.
- Green means the disk has power and answers the detector.
- Red means power off, offline, not detected, saved for power off, or stale/unusable device.
- Auto sleep after selected idle minutes.
- Auto wake / mount watch with bus rescan.
- Forget Saved Power-Off Policy button to stop automatic reboot/login power off for a selected drive.

Important:
Internal SATA hard power off can still require bus rescan or reboot depending on controller support.
The app does not store your Linux password. Persistent disk power policy is stored in the user state file, not in the system password store.
