First FAT Offset
Offset for the first FAT table on the volume. Together with the Size of One Fat Table
property, is a most important property for a FAT volume. If this property is incorrect,
many files (especially fragmented ones) may be incorrectly recovered.
Size of One FAT
Table
Size of one FAT table on the volume.
Sector Size
Sector size of the hard drive. This property is read from the boot sector of the FAT
volume and does not affect R-Studio operation.
Number of FAT
Copies
Number of FAT copies on the FAT volume.
Active FAT copy
Active FAT table number for the FAT volume. Can be set to Disabled, Auto, 1, or 2. If
it is Disabled, R-Studio processes the volume as there is no FAT table present. This
may be useful if the volume has been reformatted and thus a new FAT table is created
and the old one is deleted. In this case, it is reasonable to recover files from the
previous volume without processing the new and irrelevant FAT table. All files will be
recovered as continuous byte chains beginning from their start cluster. Unfragmented
files will be recovered successfully. If it is 1 or 2, R-Studio uses the first or second
FAT table copy, respectively. If it is Auto, R-Studio uses both FAT table copies and
decides, which FAT table copy should be used for a particular FAT table sector. This
may be useful when both FAT tables are partially damaged.
Major version
FAT version.
Minor version
FAT minor version.
Volume size
Size of the volume.

Block Size
Block size of Ext2FS file system. A block in the Ext2/3/4FS file system is similar to a
cluster in the FAT file system.
First SuperBlock
Offset
Offset of the first SuperBlock from the start of the Ext2/3/4FS volume.
Blocks Per Volume
Number of blocks in the Ext2/3/4FS volume.
INodes Per Volume
Number of inodes on the Ext2/3/4FS volume. An inode is a record describing file's
size, attributes, position on an Ext2F/3/4S volume - all information about a file, except
its name, which is stored separately. Therefore, the INodes Per Volume parameter is
equal to the maximum number of files on an Ext2/3/4FS volume.
Creator OS
The OS that created this Ext2/3/4FS volume. May be Linux, Hurd, Masix, FreeBSD,
Lites.
Major version
Ext2/3/4FS version. Usually 1.
