Frequently Asked Questions
Logical cases usually finish the same day. Physical disk damage takes 1–3 working days including cleanroom work. RAID and server arrays take 2–5 days depending on disk count. Emergency service can compress this significantly.
Logical recovery starts from a few hundred RMB; physical and RAID cases are quoted by fault severity and disk count. Diagnosis is always free, the quote is fixed in writing before work starts, and if we cannot recover your data you pay nothing.
Yes. Hong Kong and Macau clients can courier devices to our Shenzhen lab (declared as repair items, typically 1–2 days in transit), arrange handover at border crossings, or book on-site service in Hong Kong. PDPO-compliant handling and confidentiality agreements are available. See the Hong Kong service page.
In many cases, yes. We analyze the encryption implementation and recover data through unencrypted fragments, backups, shadow copies, or known weaknesses — without paying the ransom. A free assessment tells you which route applies to your strain.
Often yes. Stop all writes immediately and do not rebuild. We image every member disk, repair the failed ones, then virtually reassemble the array offline. Success depends on the second disk's damage and whether a rebuild was attempted.
All major server and storage brands — Dell, HPE, IBM, Huawei, Lenovo, Inspur, Sugon, EMC, NetApp — plus NAS (Synology, QNAP), databases (Oracle, SQL Server, MySQL, Dameng, Kingbase) and virtual platforms (VMware, Hyper-V).
