Practical examples from the world of IT and data recovery, across all types of media including HDD, SSD, RAID, mobiles, memory cards, and more.

Sometimes it takes very little for important data to teeter on the brink of being lost forever, sending its owner close to a heart attack. Most data recovery cases then become a task for an experienced specialist. Even a seasoned expert could be stumped in many cases without the availability of advanced technologies. This article discusses a modern 4TB hard drive from WD, where the absence of certain technologies could have severely complicated, if not made impossible, the data recovery process.

A damaged mobile phone and a desperate user is a scene we encounter frequently. Regardless of the reason for the mobile phone's failure, data recovery can be a complex task not only for the technician but also for his assistant, capable of peering into the silicon heart of the mobile. Data recovery demands expertise, technological know-how, finesse in handling the hardware, and in many cases, also PC-3000 Mobile - hardware and software from Acelab's laboratories.

Repairing hard drives according to "guaranteed guides" from the internet. How valuable is your data?
A hard drive can, after a fall, a collision, or even spontaneous failure, get into a state that can give a curious user with a sharp ear the impression that they can access the inaccessible data themselves. After a while of researching on the internet, loosening those strange screws, and a bit of prying with a screwdriver, "stuck read heads" appear. If the user hasn't destroyed the disk by this point, they're certainly well on their way, if they progress to the next level of the data experiment.

We received an interesting challenge: to work with an IBM IC35L020AVVA07 hard drive, featuring a 20.5 GB capacity and manufactured in 2002. The drive was used in an industrial machine since its production year. After years of reliable performance, the drive started to malfunction, causing issues with the operating system and the machine's tasks. Our mission was to create a binary copy of the disk and attempt to recover the data, enabling the operating system to be restarted.

Systémový disk a hlavní datové úložiště v notebooku tvořil pevný disk Hitachi s kapacitou 1TB. Dříve zcela běžná výbava a kapacita i dnes dostačující pro běžného uživatele.

A hard drive with shingled magnetic recording (SMR) is suitable for data backup. In case of failure of read heads or data platters, data recovery from such an HDD can be complicated. Obstacles include the way data is written and read. Furthermore, modern hard drive electronics (PCB) do not allow access to service data in the usual way and also encrypt user data on the disk. You can use a hard drive with shingled recording without even realizing it. And when it fails, it's a backup drive and you have data stored in another place. Or not?

Selhání datových ploten a/nebo čtecích hlav je u pevných disků všech značek častá vada. Pád či náraz, někdy vada materiálu a problém je na světě.
