What to do if…
your computer warns of disk errors and offers a repair that could risk data loss

Short answer

Don’t run the repair yet — copy your most important files to another drive first. Disk repairs can change or remove damaged data, so “backup first” is the safest move.

Do not do these things

  • Don’t click “Repair/Fix” before you’ve copied what you can.
  • Don’t keep using the computer like normal (updates, installs, gaming, big downloads) — that adds new writes to a potentially failing disk.
  • Don’t run multiple “fix” utilities in a row (or repeat repairs over and over) hoping one will work.
  • Don’t defragment or run aggressive cleanup tools.
  • Don’t assume cloud-sync is a backup if files might already be corrupted or syncing deletions.

What to do now

  1. Stop new activity that writes to the disk. Save what’s open if you can, close apps, and leave the computer on stable power.
  2. Choose “Skip/Cancel/Not now” on the repair prompt. Your priority is a safe copy of data.
  3. Plug in an external drive (or use another computer/network location) as the backup destination. Avoid copying onto the same internal disk.
  4. Copy the irreplaceable data first, fast: documents, photos, passwords/2FA backup codes, financial/tax files, work/project folders.
    • If you hit errors, skip that item and keep going so you don’t lose time on one bad spot.
  5. If the machine slows drastically, freezes, or starts making unusual noises: reduce stress on the drive. Copy only the top-priority folders/files and stop repeated attempts.
  6. If you have a Mac and the warning involves Disk Utility “First Aid”: copy first if you can.
    • If you can’t boot normally, you may still be able to copy files to another Mac using Apple-supported transfer options before you run repairs (for example Share Disk from macOS Recovery on Apple silicon Macs, or Target Disk Mode on some Intel Macs).
  7. After you have a backup you trust, run one built-in repair pass (the tool the system is offering). If it can’t repair, or warnings return soon after, assume the disk is unreliable.
  8. Plan for replacement. If the system indicates the disk is failing, replacement is often required — file-system repairs can’t fix dying hardware.
  9. If the computer is under warranty or you bought it recently: once your files are safe, contact the seller/manufacturer support before doing anything that could complicate warranty service. Keep a simple timeline (what warning appeared, when, what you tried).
  10. If a shop or support agent offers “reset/erase as the first step”: pause and confirm you already have your files backed up. If you don’t, ask explicitly for a data-preserving option first.

What can wait

  • You don’t need to decide right now whether to wipe/reinstall the operating system.
  • You don’t need to fully diagnose the root cause (hardware vs software) before saving files.
  • You don’t need to optimize backups or clean up storage in the panic moment.

Important reassurance

A disk warning doesn’t mean you’ve already lost everything. The safest first move is simply to switch from “fixing” to “copying,” starting with the files you can’t replace.

Scope note

This is first steps only — once your files are safe, you can troubleshoot calmly, replace hardware, or use professional help if needed.

Important note

This is general information, not professional IT or legal advice. If the device holds business-critical or sensitive data, or you’re in a warranty/return window, consider using official support channels or a reputable data recovery professional rather than repeated repair attempts.
