The following video explains the functionality provided by this add-on and shows how it works on a few real cases.
The Data Acquisition Add-on is a firmware upgrade which adds three extra features:
The standard RapidSpar device recovers data sector by sector, making an exact copy of the Source drive. With the Data Acquisition Add-on, recovered data can be optionally written to a raw DD image file on the Target drive.
In this mode the host computer is connected to RapidSpar over USB3, while RapidSpar has a direct SATA connection to Source and Target drives. The RapidSpar device employs a drive emulation system to present itself exactly as the original Source drive to the host computer. Here is how it works:
If the Source drive gets stuck processing a bad block of sectors, the RapidSpar device will:
The host computer maintains a problem-free, uninterrupted connection to the emulated Source drive at all times, even while the real Source is being repowered! This ensures that the computer will never freeze, crash, restart, or drop the connection due to problems with the Source drive. Bad sector processing will be from 5 to 25+ times faster and safer in comparison with using software directly on the Source drive.
All of this functionality is provided entirely by the standalone RapidSpar device with no software or hardware requirements for the host computer.
RapidSpar maintains a live sector map within its project metadata saved on the built-in SSD inside the RapidSpar device. With the Data Acquisition Add-on, this sector map can be parsed to create a .csv file which shows a file listing with the exact number of good and bad sectors within each recovered file. This information is usually used to communicate the results of the recovery to the customer to increase transparency and prevent conflicts.
