# BLOG - LABnotes

Notes from our laboratory on both common and less usual data recovery cases. You have the opportunity to glimpse into our daily work, which is often challenging and requires specialized technological procedures.

For many of us, the mobile phone has become an indispensable part of everyday life. Some phones are more resistant, others not, and so one of the common causes of mobile phone failure is oxidation of the motherboard, which results from the intrusion of moisture. Rain, a dip in the pond, or in the sea... there are many causes of oxidation. If there is a lot of moisture inside the phone, oxidation can seriously damage some parts of the phone.

Flash drives are not among the most reliable data media, and while they use a similar memory chip foundation as those found in SSDs and mobile phones, most flash drives are technologically inferior. When you add the frequently low quality of flash drive components, you end up with a data medium that should only be used to transfer data backed up elsewhere or to store non-essential data. We ultimately resolved this case successfully.

  ![Záchrana dat z externího disku. V boxu Axago až do pádu fungoval disk Seagate](https://www.exalab.cz/images/blog/EN2404292-zachrana-dat-z-Azago_Seagate-1200-fw.jpg)

##  [ Data Recovery from an External Drive. Seagate Drive Worked in Axagon Box Until It Fell ](https://www.exalab.cz/en/blog/from-practice/labnotes/data-recovery-from-an-external-drive-seagate-drive-worked-in-axago-box-until-it-fell)

After upgrading the notebook, this Seagate hard drive was placed in an external box and used as external storage. A fall proved to be its downfall; it was not completely destroyed, but it did not escape serious damage. The diagnosis of this disk was not very favorable, but a significant amount of data was still recovered.
