We recover your data professionally and are very experienced with defective write/read heads.


If the write/read heads crash onto the ferromagnetic surface of a hard drive it's called "headcrash". This often happens after a fall or concussion, but wear or temperature fluctuations are also a possible cause. Attingo has long-standing experience with saving data from defective hard drives after a headcrash.

Attingo helps with headcrash

Attingo recovers for more than 20 data from hard disks, that are damaged by a headcrash.

  • Cleaning contaminated surfaces in the cleanroom laboratory

  • Swapping defective heads

  • Swapping defective bearings

  • Manipulation of damaged firmware caused by a headcrash

Clicking? Buzzing? Indication of a headcrash

  • Rhythmical clattering of the write/read heads

  • Humming or grinding noises from the inside of the hard drive

  • Hard drive starts, clatters a few times and then winds down again

  • Directories or files are incomplete or can't be opened anymore

  • I/O Errors

In over 98% of cases we are able to reconstruct the data after a headcrash.

Common causes for a headcrash

  • External hard drive falls down

  • Notebook cover was slammed shut

  • Concussion of the notebook or PC

  • Temperature fluctuation or altering barometric pressure

  • Material wear

Be careful after a headcrash

Since the heads crash onto the data carrier discs, you have to be extra careful. We recommend to refrain from trying to safe the data on your own, because that may minimize the chances of a successful data rescue later on.

  • Very important: don't turn the hard drive on again. Defective write/read heads may cause fatal damage induced by the headcrash and in the worst case a data rescue becomes impossible.

  • Don't manipulate the data carrier. The finest dust particles inside a hard drive may cause a headcrash. Therefore defective heads should always be exchanged in a clean room laboratory. Experience shows that self-experiments almost always worsen the damage. Attingo has in-house clean room laboratories .

  • We advise you on our diagnosis services and the process of the data rescue. If you need an express data rescue, our staff is there for you all around the clock.

  • Take a look at our packaging tips so that your data carrier arrives in our laboratories safely.

General information about headcrashes

A headcrash may cause fatal surface damage on the magnetic layer inside the hard drive, if it isn't detected timely or if self-experiments are made. The heads are floating on an air cushion only a few nanometres above the magnetic surface with 15.000 revolutions per minute. If the air cushion is damaged - e.g. spots on the discs induced by a headcrash - the heads may start swinging and crash onto the magnetic layer of the hard drive, causing consequential damage. Defective write/read heads may also damage the hard drive.

Unter Umständen eine frühere Bekanntgabe einer auftretenden Zeitverzögerung (in dem Fall bestellte Teile zur defekten Festplatte), wobei wir durchaus davon ausgehen, dass wir die Informationen erhielten, sobald diese zur Verfügung standen.
