Home / Extras / ZAR 8.4 Manual / General usage / Analysis run

Analysis run

This page displays status and progress of the automated analysis. The analysis typically involves the following steps:

  • Raw disk scan, when objects of interest like file or filesystem fragments are identified.
  • Volume parameters detection, mostly computational process deriving several key volume boot sector entries from the data collected during raw scan. Note that even if boot sector is present on the volume, the values will be computed anew anyway. Generally, we do not put much trust into the single data structure on the damaged  volume, for doing so will make the process prone to "single point of failure" errors.
  • Parsing the filesystem, during which the final results are generated: file and directory lists are collected and sorted to reconstruct the directory tree.

Please avoid making estimations about the time of processing based on the information displayed, for the following considerations:

  • Presence and location of the bad blocks has an immense effect on the raw scan speed, even if the bad block avoidance is configured in bad sector processing options.
  • Some recovery steps may be computationally and/or memory intensive. ZAR solves quite sophisticated equations to achieve proper recovery. The complexity of these equations depends upon the state of the volume being recovered and the time needed to solve them is thus hardly predictable.

Note that it may take some time to abort the analysis run (either by pressing "<<Back" button or by exiting the application). Delay of up to five seconds even on a decent machine does not indicate a malfunction. The internal state of the software is quite complex and may take quite a long time to clean it up and relinquish any unneeded resources.

I tried a couple of programs to recover images from a "broken" SD card and this one was the only one to recover all the images intact. Every case is different of course but you lose nothing as it is free. Wouldn't be without it now. I have no connection with ZAR btw, just a happy user of the software. HTH
