PC-3000 DE. Overview of PC-3000 Data Extractor reports

Sometimes data recovery engineer need to prepare a report for customer. We are going to overview what kind of reports can be provided by PC-3000.

Good and bad files

Most frequent task. It can be used to demonstrate customer positive result before payment or to ask which files are most critical if drive is going to dead.

To prepare such report you need to create a snapshot (virtual filesystem) firstly:

After that you have three options:

• Make shapshot use legend
• Make snapshot use metadata
• Make snapshot use map

To create a report based on reading status you need to use “Make snapshot use legend”. Then if you want to select only COMPLETELY good files (with ALL green sectors) you need to select “EXCLUDING the legend” and mark all types of bad reading legend (black, red, green, dark green and orange):

Please note, that if you choose only “Sector was read successfully” legend (green sectors) and “Including the legend” parameter Data Extractor will put in report files which have at least one green sector, but it doesn’t mean that file is readible.

For example we have a three image files, one is fully readed, second is readed partially and third is placed only on BAD sectors:

If you selected “Excluding legend” and all types of bad reading legend – you will get in resulted snapshot only 1.png. If you selected “Including the legend” and only green legend – you will get in result 1.png and 2.png.

After that snapshots with good and bad files can be exported to *.acerep file and sent to customer for inspection using DEViewer:

*.acerep file format is opened – it’s just sqlite database compressed by zlib:

So if functionality of DEViewer isn’t enough you can create your own personal cabinet and web application for customers based on huge number of opensource libraries like pako, jsTree etc.

DEViewer reports doesn’t contain any data about legend. If you need to provide customer two reports, one with good files and one with bad – you need to create two separate reports.

General report about errors in selected files

This type of report convenient to use when you need quickly estimate total size of all selected files and selected files which have problems. Result will looks like:

CSV report

This type of report is helpfull when you need to calculate MD5 and SHA1 hashes. Check more details by this link.
