Disk inspection, partition tools and image workflows in one native window. DiskSalv is still in development.

disks.overviewLists every physical and virtual disk, including unmounted partitions and synthesized APFS containers. Live auto-refresh, capacity bars, device paths.core

smart.monitorS.M.A.R.T. health and temperature via diskutil + optional smartmontools: SATA and NVMe, with critical-warning escalation for failing drives.health

ext4.readerNative read-only ext4 browser: traverse directories and extract files from Linux partitions without mounting. Extent-tree and 64-bit filesystem aware.no mount

partitions.manageCreate, delete, format, resize, rename and repair supported GPT and MBR partitions. Destructive operations show a typed confirmation in the app.GPT · MBR

images.toolsCreate DMG images, convert supported image formats and restore images. Source checksum verification is available for supported image formats when selected.DMG · ISO

files.browserBrowse mounted partitions with copy, delete and rename. The browser treats symbolic links as links instead of opening their targets as folders.files

/ safety.md

A disk tool that can reshape hardware has to be careful. DiskSalv treats your data as the thing worth protecting.

Startup disk lockout

DiskSalv checks the target against the startup disk before destructive disk operations and refuses the operation when it cannot verify the target.

Typed confirmations

Destructive disk dialogs require typed confirmation before their action buttons unlock. Check the selected device and keep a backup before changing partitions.

Optional image verification

For supported disk images, you can request source checksum verification before restoration. This check does not replace a backup or post-restore validation.

Read-only where it matters

The ext4 reader and hex viewer default to read-only. NTFS and ext4 are never written blindly, and the browser refuses to follow a symlink out of its volume.

Audit log

Disk operations are recorded in a local log under ~/Library/Logs/DiskSalv/ for later review.

Controlled command execution

DiskSalv calls system utilities with validated device identifiers and structured arguments.
