FAQ

Frequently asked questions

What you most want to know about on-site service in Guangzhong

Why do you tell me not to keep powering it on?

Powering it on lets the head scratch the platter, spreads bad sectors and overwrites recoverable data. Power it off — the sooner we handle it, the higher the success rate.

How long does recovery take?

Logical recovery usually finishes the same day; cleanroom or RAID work takes 2–5 working days, and we give you an estimate when we take it on.

How do I avoid this happening again?

Set up automatic local plus off-site backups — a few hundred RMB covers most risks. We can configure it for you after recovery.

Can the drive still be used afterwards?

Most logical-fault drives can; clicking drives should be replaced and backed up first.

How do I avoid this again?

Set up automatic local plus off-site backups — a few hundred RMB covers most risks.

Do you fix desktops on-site or must I bring it in?

Most faults can be fixed on-site — our technician brings tools and common parts. If specialist equipment is needed, we'll explain and agree on a time.
