This section
shows available information on hard drives and logical disks. These
properties depend on the drive/disk type and appear only when
applicable. Under Windows NT/2000/XP/2003/Vista/2008/7, an IDE drive/disk may be represented as a SCSI
device, that is why the SCSI
Address section appears under
these OSes for those drives/disks.

Windows 9x/ME adds the following
properties:
|
Int13 Drive Number
|
128 for the first hard
drive accessible through Int13, 129 for the second one, etc.
0...128 for drives and other devices accessible through a Windows
9x/ME protected mode driver, if their Int13 device option is
disabled. R-Studio
can use Int13 disk access, and for some
drive types, like SCSI devices, Int13 access is preferable. You may
consider enabling the Int13 device option in the Windows Device
Manager for such devices.
|
Int13 Extension Version
|
Int13 Extension
Version Support for hard drives. Extended Int13 support is
necessary for large drives. If this property is zero, Extended
Int13 is not supported, otherwise, it shows Extended Int13 standard
version, the large, the better.
|
This section
shows properties that control access (read and write) to hard
drives and logical disks. They are set to their optimal values and
should be altered only if access problems appear.
More information...
Drive Control
|
|
Maximum transfer
|
Maximum data size that
can be read or written during a single access to the drive. If
there are problems with drive access, decrease the value of this
property
|
I/O Unit
|
Data size read or
written during a single access to the drive is a multiple value of
this property. If there are problems with drive access, decrease
the value of this property
|
Buffer Alignment
|
Drive data transfer
buffer is positioned at an address multiple value of this property.
If there are problems with drive access, increase the value of this
property.
|
These three properties
are set by OS drivers. If the drivers set incorrect values,
problems may appear during data transfer operations. You can alter
them until data transfer becomes stable.
|
I/O Tries
|
Number of read/write
tries during access to the drive. If there are bad sectors on the
drive, increase the value of this property. This may help to
successfully read those sectors. Sometimes, if the
I/O Tries parameter is set too large and there are some
unreadable sectors on the hard drive, the hard drive-controller
pair may refuse to perform any successive read/write operations
with the entire hard drive when it fails to read/write such
sectors. In this case, set this parameter to zero.
The default value is
specified on the Settings (Bad Sectors)
panel.
|
A
partition is a continuous area on a hard drive, characterized
by its offset and size. There are partitions on basic disks,
dynamic disks, and recognized volumes and partitions.
R-Studio treats s like partitions.
More information...
Partition Offset
|
Initial offset for the
partition.
|
Partition Size
|
Size of the
partition.
|
Partition Type
|
File system type for
the partition. If the record in the drive partition table is
incorrect, this property may differ from the actual file system
type for this partition. Still, R-Studio will process
this partition correctly, as it does not use this
property.
|
Partition number
|
Appears under Windows
NT/2000/XP/2003/Vista/2008/7 only. Shows the number of the
partition on the physical drive.
|
For s and recognized partitions,
Partition Offset and Partition Type
properties can be manually
corrected.
|
A
compound
volume is a union of several
partitions or other disk objects. Each union type has its own
rules, unique for each compound volume type. Among compound volumes
are: Volume Sets (RAIDs Level 0), Mirrors (RAIDs Level 1), RAIDs4/5/6 (RAIDs Level 4/5/6), both physical and created by
the user (Virtual Volume Sets, Virtual Stripe Sets, Virtual Mirrors, Virtual RAID5).
More information...
Main properties of
compound volumes are parents (disk
objects from which a compound volume is created) and their order.
These properties may be viewed in the Parents tab.
For user-created compound volumes these
properties may be altered.
|
Raid Block Size
|
Data block size for compound volumes of RAID
(Level 0-5) types
|
LDM disks and volumes are volumes controlled by Logical Disk Manager
(LDM). They are represented on a hard drive as a LDM database
rather than partition tables. Under Windows 2000/XP/2003/Vista/2008/7, LDM disks are also called Dynamic
Disks.
More information...
Offset of Logical
Disk
|
Initial offset of a
logical disk on a hard drive. For disks, initially formatted by
LDM, this value is often 31.5KB, for
converted disks, it may be larger.
|
Supposed Parents
Count
|
Supposed number of
parent partitions for compound LDM volumes. If the LDM database is
not damaged, the value of this property must be equal to the number
of parent objects in the Parents tab for the disk
object.
|

A
File System
(FS) volume is a disk object
where a certain, supported by R-Studio, file system
is present. There are two FS volume types: FS volume on a regular
disk object and a recognized volume, found by a scan process. FS
volume properties depend on volume's file system and
type.
7.1.NTFS Volume properties
These properties
are present for all NTFS volumes and represent their main
properties. For recognized volumes, these values can be altered.
More information...
NTFS Information
|
Regular volumes
|
Recognized NTFS
|
Recognized
volumes
|
Cluster Size
|
Cluster size for the
NTFS volume.
|
MFT record size
|
Size of one MFT record
describing one file on the NTFS volume. This is an important
property of any NTFS volume. Its common value is 1KB. If this
property has incorrect value, many files may be incorrectly
recovered.
|
Sector Size
|
Sector size for the
physical drive. This property is read from the boot sector of the
NTFS volume and does not affect R-Studio operation.
|
Index Block Size
|
Index block size for
the NTFS volume. This property determines binary trees used to
store NTFS folder structure. It does not affect R-Studio operation.
|
MFT position
|
MFT offset from the
start of the NTFS volume.
|
MFT Mirror Position
|
Second MFT copy offset
from the start of the NTFS volume.
|
Volume size
|
Size of the NTFS
volume. This property does not affect R-Studio operation.
|
7.2.FAT Volume properties
These properties
are present for all FAT volumes and represent their main
properties. For recognized volumes, these values can be altered.
More information...
FAT Information
|
Regular volumes
|
Recognized FAT
|
Recognized
volumes
|
FAT Bits (12,16,32)
|
FAT type. 12 for the
FAT12, 16 for the FAT16, 32 for the FAT32.
|
Cluster Size
|
Cluster size for the
FAT volume.
|
First Cluster Offset
|
Offset of the first
cluster from the start of the FAT volume.
|
Boot Directory Cluster
|
(For FAT32
only.) Cluster number where the root
directory starts on the FAT volume where the logical disk
resides.
|
Root Directory Offset
|
(For FAT12 and 16
only.) Root directory offset from
the start of the FAT volume.
|
Root Directory Length
|
(For FAT12 and 16
only.) Root directory length for the
FAT volume.
|
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

7.4.Recognized Volume properties
These properties
are present for all recognized volumes, regardless of their file system type. They
estimate how reliable those volumes are recognized. This is useful
for fast search for, and selection of, optimally recognized volume
to recover.
More information...
Parsed File Entries
|
Number of files
proving that this recognized volume existed. May have any
non-negative values. The main property characterizing the
reliability of volume recognition. The larger it, the higher
probability that this recognized volume has file system properties
that have been correctly found.
|
Parsed Boot Records
|
Number of boot records
proving that this recognized volume existed. May be
0 or
1. This is
the second important property characterizing the reliability of
volume recognition.
|
Estimated Size
|
Estimated size of the
recognized FS partition/volume. This property shows the most
probable size of the recognized FS partition/volume.
Alternatively, Size
and Partition
Size are set to the highest possible
values in order to recover the maximum number of files.
