Data recovery from a formatted external hard drive is possible, but the success rate depends on several factors. It is important to stop using the device immediately after formatting to increase the chances of a successful recovery. Windows users can recover up to 500 MB of data for free with the right tool, while Mac users can use Time Machine's built-in backup and recovery application. To understand the hazards and follow the proper process for data recovery, read on. When it comes to recovering data from a formatted hard drive, it is important to understand that different types of devices store data differently.
This affects the viability of retrieving it after formatting. For less sensitive data, I recommend using the ATA secure erase function instead of something like DBAN, as it is faster and meets NIST standards for security. Recovering data from a formatted drive requires a lot of searching and confirming the integrity of the data to determine success. Unless you use a tool or method to write 0s to every bit of the drive, the data is potentially recoverable.
However, success decreases if more than just the operating system is reinstalled. To recover data from a laptop after formatting, you need to use a reliable data recovery tool. Windows users can use a free tool to recover up to 500 MB of data, while all trial versions of commercial solutions allow you to preview the data that can be recovered. It is important to take appropriate precautions to keep your data secure at all times and make data loss a distant problem. I personally physically destroy any drive that has sensitive data.
Additionally, both MacOS and Windows offer free backup and restore tools that you should use regularly.
