Usage

NBL DiskDuplicator quickly reads the entire contents of any diskette into memory. The disk image can be saved as a file on your hard disk and reloaded at any time. Unlimited copies can be made from this disk image file without swapping back the original diskette. Copies are track-for-track identical to the original.

•	Benefits

•	Special Considerations


Who Uses NBL DiskDuplicator

Systems Administrators and MIS Managers

Manage your software licenses efficiently. Create install diskettes on demand for local users, or share disk images over networks and email for remote users.

Software Developers

Quickly master multiple disk sets for new software releases. Share disk image files over a network for faster and remote duplication on multiple machines. Duplicated diskettes are track for track identical to the original master diskettes, even the empty tracks are duplicated. Copies are formatted, duplicated and, optionally, verified in one pass across the diskette.

Individual Home and Business Users

Ever needed to reinstall your registered software, only to discover one of the diskettes is missing or corrupted? Software manufacturers recommend making backup copies of their install diskettes - with NBL DiskDuplicator you can do this quickly and easily. You can even store the backup diskette images on your hard disk and back them up onto other mass storage media like streaming tape or read/write optical drives for permanent archival.


Benefits

Makes an Exact Duplicate of any Diskette

NBL DiskDuplicator copies all of the data, including the volume label, serial number and even empty tracks. Strict data verification and checksums are performed to insure that duplicated diskettes are track-for-track identical to the original.

Keeps Working

NBL DiskDuplicator runs in the background without stopping your other applications - or your progress on other tasks.

Uses all of your Floppy Drives at the Same Time

You can run multiple instances of NBL DiskDuplicator on a single machine for faster duplication. All known floppy drives are supported: 5 1/4, 3 1/2 High Density, Low Density, even the latest 2.8 megabytes drives.

Saves Time and Money - Send Diskettes Electronically

No more excuses for lost or delayed packages.  Distribute software to any other NBL DiskDuplicator user via network or modem

Detects Bad Disks

NBL DiskDuplicator will ONLY DUPLICATE uncorrupted disk images onto uncorrupted diskettes so your data integrity is ensured.

Reading a Diskette into Memory

To read a diskette into memory, take the following steps.

1.	Insert the diskette from which you want to read in drive A or drive B.

2.	Click the drive in which the diskette sits, A or B.

3.	Click Read Master.

NBL DiskDuplicator does the following tasks.

A.	Shows a thermometer as it reads the diskette into memory.

B.	Displays the diskette label, if any, and format of the diskette read into memory.

C.	The contents of the diskette are now in memory. This is called a disk image. You can now make copies of the diskette and/or save the disk image on your hard drive so you can reload it again in the future.


Saving a Disk Image

Saving a disk image file is DISABLED in this shareware version.

To save a disk image so you can load and duplicate from hard disk or networks, take the following steps.

1.	Type a descriptive name, title, which is stored in the disk image file so you can uniquely identify this disk image.

2.	Click Save Image File.

The Save As dialog box appears.

3.	Select the existing filename or type a new name for the disk image file you want to save.

4.	Save the disk image to the current location or select another location.

5.	Choose OK.


Loading a Disk Image

To load a disk image file, take the following steps.

1.	Click Load Image File.

Note	If a disk image with unsaved changes is already loaded, you are asked if you want to save the current disk image.

The Open dialog box appears.

2.	View the disk image stored at the current location or select another location.

3.	Select the name of the disk image file you want to load.

Load moves a disk image into memory so you can begin duplicating.

4.	Choose OK.

Note	After the disk image file is loaded, NBL DiskDuplicator verifies the data is uncorrupted.

Note	NBL DiskDuplicator compares the format of the loaded disk image to your disk drives and automatically selects the Drive (A or B) that matches the disk image.


Duplicating a Disk Image

To duplicate a disk image file, take the following steps.

1.	Insert a blank diskette into the appropriate drive.

Before you can duplicate a disk image, you MUST currently have the disk image in memory, Read the Master, or Load a Disk Image.

2.	Select the correct drive (A or B).

3.	Click Duplicate.

4.	NBL DiskDuplicator asks if you want to overwrite the disk.

Note:	Before proceeding, be sure the correct diskette is in the drive. If you click OK, the previous contents of that diskette is overwritten.


Using the Shareware Version 1.1

The NBL DiskDuplicator shareware program is the same as the full retail version of the product except the Save Image File feature has been disabled. You can however use the sample disk image file (.DSK files) supplied to see how NBL DiskDuplicator duplicates diskettes from disk images.

To duplicate a disk image:

1.	Load a disk image file by clicking Load Image File and selecting one of the following disk images included with the shareware version. Although the disk images provided are lower density,  the disk images can be copied to low or higher density diskettes as long as 5.25 is copied to 5.25 or 3 1/2 is copied to 3 1/2.

File Name	File Capacity
360K525.DSK	Disk image of a 360K (low density) 5.25" floppy
720K35.DSK	Disk image of a 720K (low density) 3.5" floppy
2.	Insert a blank diskette with the appropriate capacity into the appropriate drive.

3.	Select the correct drive (A or B).

4.	Click Duplicate.

5.	NBL DiskDuplicator asks if you want to overwrite the diskette.

Note:	Before proceeding, be sure the correct diskette is in the drive. If you click OK, the previous contents of that diskette is overwritten.


Read/Write Workaround

If you do get READ ERROR (track0, head0) or WRITE ERROR (track0, head0) while reading or writing to a diskette that is otherwise fine, you may have a configuration related conflict due to some TSR or non-standard BIOS or some aggressive memory manager that affects the normal operation of NBL DiskDuplicator. This is a very rare occurrence and please proceed as follows to resolve this:

1.	Use NBL DiskDuplicator to copy the same diskette on another computer (try one or two different types of machines). If it works on another computer, you have the configuration conflict, go to step 3.

2.	On the computer on which you get the error:

a.	Place the diskette in the drive.

b.	View its contents with Window's File Manager

c.	Use NBL Disk Duplicator to read and write to the diskette. If it works after viewing the contents of the diskette with File Manager, you have the configuration conflict, go to step 3.

3.	Type WORKAROUND=1 in NBL.INI file in Windows directory. Default is = 0.

4.	Relaunch NBL DiskDuplicator and try to read or write to the diskette again.

Note:	 In many cases the speed of the application can be quite slow. We are working on the performance issue in the workaround option.

5.	To help us identify and solve this problem, please fax the following information:

1.	Hardware and Software Configuration

2.	If the workaround option worked ?

3.	If the performance was slow and how much ?

Save disk image to the hard drive to speed the duplicating process. It is faster to load a disk image and duplicate from the hard drive then reading the master diskette again. Typically loading a disk image from a hard drive takes 3-4 seconds, as opposed to 1 minute and 40 seconds loading from a 3 1/2 1.44 MB diskette.


Multitask  Duplication Tip
Simultaneous Duplication Tip

Launch several NBL DiskDuplicators at the same time so each can write to a different drive simultaneously.


Remote Duplication Tip

Save disk images on a network and distribute from any remote site that has NBL DiskDuplicator. You can duplicate whether onsite or offsite and produce an exact replica in real time.


Quality Duplication Tip
Quality Assurance Duplication Tip

For normal use Verify Copies, Compare to Image, and Always Format can be deselected since NBL DiskDuplicator has extensive internal error checking. When you are duplicating large sets of diskettes, you can use Verify Copies, Compare to Image, and Always Format on a random sampling of diskettes to validate quality control..
