Before making changes
Start with safe, useful checks
- Record the hardware maker, exact model, operating system, and installed version.
- Confirm that a backup exists outside the server before updates or storage changes.
- Review disk-health alerts without immediately removing or reformatting a drive.
- Document shares, users, network settings, and encryption keys before configuration changes.
Do not install a BIOS or firmware file unless the exact model matches, the manufacturer’s instructions are clear, important data is backed up, and stable power is available. Interrupting firmware installation can leave a device unable to start.
