Professional data recovery from all types of hard drives
DataHelp has over 35 years of experience recovering data from all major hard drive manufacturers — Seagate, Western Digital, Samsung, Toshiba, Hitachi (HGST), Fujitsu, Maxtor, Quantum, Transcend, IBM, HP, Intel and Dell. Our founder has been active in professional data recovery since 1990, and the DataHelp laboratory has operated continuously since 1999. We handle desktop, laptop, enterprise and server drives from 1GB historical IDE models up to the latest 20TB+ SATA and SAS drives.
Hard drive damage is most commonly caused by a drop or physical impact, power surges, mechanical component wear, or manufacturing defects. Typical symptoms include unusual sounds (clicking, squealing, grinding), system slowdowns, disappearing files, or complete boot failure. If you notice any of these, it is critical to disconnect the drive immediately and hand it over to specialists — every further power cycle reduces the chance of recovery.
Our laboratory in Prague operates ISO Class 5 laminar flow boxes that provide a controlled environment for safe disk opening and internal component work without dust contamination. We maintain a warehouse of over 10,000 catalogued donor drives for read head, motor and PCB replacements across most models. Every recovery is performed with original ACE Lab PC-3000 tools and firmware-level diagnostic equipment.
Diagnostics are free of charge and the entire process is transparent — we quote a fixed price upfront and recovery only starts after your written approval. If recovery fails, you pay nothing.

If the disk makes unusual sounds (clicking, squealing), disconnect it from power immediately.
Contact specialists as soon as possible — every further attempt reduces recovery chances.
Entrust the disk to a specialised laboratory with laminar flow box equipment and donor parts in stock.
Document the original behaviour (sounds, messages, symptoms) — it helps us prioritise diagnostics.
Don't attempt DIY repairs - you risk permanent data loss
Don't run disk repair tools (CHKDSK, fsck) on physically damaged disks
Don't open the disk - laminar flow box environment required
Don't shake or tap the disk hoping to 'fix' it
It is important to distinguish between data recovery and drive repair. Data recovery focuses on retrieving your files from a damaged or non-functional disk, while drive repair means restoring the disk to a fully functional state for continued use.
Mechanically damaged drives are not normally repaired due to the high cost of the repair and the limited reliability of any repaired drive. In some cases — firmware corruption or service area damage — the drive can be technically repaired, but this process requires complete reinitialisation and service area recalibration, which destroys all stored data.
For these reasons DataHelp does not offer drive repair. Our specialisation is data recovery, even from mechanical damage, firmware failures or service area corruption. After recovery we return your data on a new, verified medium — the original drive is never reused.
If your system starts behaving unusually — failing to boot, showing a Windows blue screen, or the computer not recognising the drive at all — the cause may be drive failure. Any further write attempt on a failing drive can overwrite sectors where your data still resides, dramatically reducing the chance of a successful recovery.
We therefore strongly recommend turning the computer off immediately and contacting us. The fewer interventions on a damaged drive, the higher the chance of recovering your data intact. Do not run CHKDSK, fsck or any third-party recovery software on a physically failing drive — these tools assume a healthy device and will accelerate degradation.
HDD data recovery is a highly specialised, technically demanding process that depends on the type and extent of damage. For mechanical problems such as a broken read head or platter damage, the work must be performed inside a laminar flow box to minimise the risk of dust contamination. Head replacement is one of the most demanding procedures — incorrect handling can cause permanent data loss.
Another common cause of hard drive failure is faulty internal electronics, which can prevent data access or cause complete drive failure. Repeatedly powering on a drive in this state often leads to irreversible platter damage, significantly reducing the chance of recovery.
By entrusting the drive to specialists, you ensure it is analysed and recovered using professional tools that minimise the risk of permanent data loss. Do not attempt self-repair — amateur interventions often cause further damage. Our team has over 35 years of combined industry experience, operates ISO Class 5 laminar flow boxes, and has immediate access to 10,000+ catalogued donor parts.
