Before handing over the device
Customers should back up important files where possible, remove unnecessary personal files, and share passwords only when required for the specific service.
Repair work should be explained
The technician should explain whether the work needs Windows login, drive access, or only hardware inspection. Many hardware checks do not need personal file access.
Recovery-first handling
For missing files, clicking drives, or format prompts, avoid repeated attempts. Continued usage can overwrite recoverable data or worsen drive condition.
