View Logical Sectors on Volume


BestCrypt Volume Encryption software is easy in use and does not require from the user any special knowledge of location of volumes (like C:\ or D:\) on physical disks.The user should only run encrypt operation once and then mount volume (i.e. open it for access) or dismount it (i.e. close access to volume).

But sometimes it may be interesting and useful to take a look how Windows places volumes on physical disks in real life, on your concrete computer. What volume sectors contain, how the sectors look in encrypted and decrypted state, what filesystem structures contain. Especially if the volume has parts on different dynamic physical disks. For example, if Striped Volume consists of two parts on two hard drives, first 128 sectors of the volume are on first hard drive, next 128 sectors are on the second drive, next 128 sectors are on the first drive again and so on.

Taking a look at the same sector in encrypted and decrypted form is useful if you want to analyze how BestCrypt Volume Encryption encrypts concrete sectors. For example, when an array of sectors is filled in by zeros. Using XTS Encryption Mode guarantees that contents of the sectors will be completely different, but probably you should look at the effect by your own eyes.

To view contents of the sectors belonging to some volume, select the volume in main window of the program and run Sectors->View sectors on selected volume command. The following window will appear:

View sector on volume

The window shows general information about the volume, like label and size in sectors. Sectors on physical disk(s) combo box contains list of physical disks where the volume resides. It can be one only physical disk if type of the volume is Simple or three and more disks if it is RAID-5 volume.

You can look at contents of any sector of the volume by entering its number in the Logical Sector Number edit box. The program will display corresponding physical disk and physical sector numbers. Besides of this, if the volume is encrypted, you can look at the sector contents both in encrypted and decrypted form by checking the View decrypted sectors checkbox.

Note that View sectors on selected volume command is enabled only for the user with Administrating privileges to avoid the case when ordinary user could look at contents of files belonging to other users.
