View Drive Information |
 |
|
|
|
|
 Shows
exactly how your BIOS recognizes the drive. Indicates drive size, total
sectors, drive geometry including cylinders, heads, and sectors, and whether the
drive can be accessed using extended Int13 calls or traditional Int13.
This is very useful to see if the
BIOS has recognized the hard drive properly. Incorrectly recognized hard
drives can cause serious problems when installing an operating system. |

 Scans
a drive to determine and report if any sectors are unreadable. Unreadable
sectors (also called bad sectors) can cause serious problems for operating
systems.Many modern drives have a
technique to mask unreadable sectors by reassigning them to a spare sector.
When an unreadable sector is reassigned, it appears that the unreadable sector
is no longer bad. Some drives require that the unreadable sector is
written to before the assign occurs which is why a drive that develops bad
sectors often needs to be erased to eliminate all the unreadable sectors.
If a drive keeps developing bad sectors, then it is likely that something
mechanical in the drive is at fault and the data on the drive is in serious
danger.
Use LDT to scan the entire drive on a regular
basis to make sure the data is safe! Errors can be printed on an attached
local printers. |

View or Edit Partition Table |
|
|
|
|
|
 Allows
complete Partition Table analysis and editing via easy menu driven dialogs.
The partition location is displayed on the
graph bar at the bottom.
Each partition is listed along with its
type, size, active status, and position within the partition table.
The partition order can be easy changed by
moving partitions up or down in the list.
|
 Choosing
Edit will drill down the partition level details and allow modification of
any values.The partition type,
active status, start LBA, number of sectors, size, CHS type, both actual and
stored starting and ending CHS values.
A change to the start LBA or number of
sectors will automatically adjust all the CHS values or vice versa. |

Copy Sectors |
|
|
|
|
|
 Copies
sectors from one part of a drive to another part, or from a source drive to a
target drive. The direction
of the copy is automatically selected to ensure that the copy is done properly
even when the source and target areas to be copied overlap.
Now LDT has a scripting feature that allows you to
automate more than one copy sectors task. You can copy from a floppy file
to hard disk, hard disk to file, hard disk to same hard disk, or hard disk to a
different hard disk. |

Erase Entire Drive |
|
|
|
|
|
 This
is VERY handy to have when selling or even throwing away that old
hard disk.
Erases
a drive using two methods. Which method is needed depends on the level of
security desired. Whether just making sure a virus is completely
destroyed, returning a drive to a factory fresh empty state, or erasing personal
or critical information before selling or throwing the drive away, this erase
function can handle the job!
Of course,
LDT always makes the user type the word 'yes' in and choose accept before any
data is erased.
|
 The
first method simply writes 0's to every accessible sector on the drive,
effectively erasing everything and returning the drive to a factory fresh empty
state.The second method is much more
secure in that it will write 7 random passes of data followed by a final pass of
all 0's to every accessible sector on the drive. This takes 8 times longer
than the first method, but is used when the data on the drive absolutely must be
destroyed. |

View, Search, or Edit Entire Drive |
|
|
|
|
|
 Allows
any sector on the drive to be viewed, searched, or edited.
Both the hexadecimal values and characters are
displayed simultaneously along with a graph bar of the current position on the
drive. Editing can be done
by entering the hexadecimal values or typing the actual characters.
Searching can be done by specifying the text to
search for, or the actual hexadecimal bytes to search for. Options to
ignore case, enable XOR, and enable unicode searching assist in locating data.
XOR mode supports flipping all the bits in the
sector to reveal the information if the sector was written as an XOR sector.
This is common among RAID5 arrays. XOR also supports editing mode. |

Analyze or Update Boot Sectors |
|
|
|
|
|
 Analyzes
a boot sector on a selected partition to determine if it is a recognized one and
reports what is found.Updates partition
boot sectors with any of 13 common boot sectors for FAT, FAT32, and NTFS file
systems. Automatically suggests which boot sector based on partition type,
but allows user to override and choose any boot sector if desired.
A special boot sector has also been included that
allows DOS users to boot DOS partitions up to the 7.8Gb limitation. Before
this boot sector was available, DOS partitions after 2Gb on a drive would not
boot properly even though DOS could access them fully. |

Blink Drive Light |
|
|
|
|
|
 Blinks the drive light or lights
to indicate which drive in the BIOS correlates to the actual physical drive or
drives.
Blink drive light also works with RAID arrays and
will actually blink all the members of the array. |
