Definition of USB flash disk Mass Production

The production software USB disk production tool (PDT) is a USB flash disk production tool. Unlike our players, USB flash drives are made up of one or two USB flash drives at a time. They are produced in batches. They are connected to USB hub using a computer and 8 to 16 (or more) USB flash drives at the same time, then, use PDT to write the same data to multiple USB flash drives to complete the final process of USB flash drive production. Therefore, PDT is named after the mass production software-that is, the specialized software for the factory to produce a large number of U disks.

After the mass production software enters the hands of players from the factory, we find that the function of the mass production software is to write the corresponding data to the U disk, so that the computer can correctly identify the U disk and make the U disk have some special features. The USB flash disk is composed of the Main Control Board + flash + shell. When the main control board is welded to the blank flash and then inserted into the computer, because there is no corresponding data, the computer can only identify the main control board, but cannot identify the flash, therefore, the USB flash drive letter is displayed on the computer, but the double-click drive letter shows that the USB flash drive is not inserted, just like inserting a blank card reader. In fact, at this time, the USB flash drive is almost a card reader. Therefore, to let the computer identify the blank flash card, it is necessary to write the corresponding data to the flash, which includes the size of the USB flash disk, the chip used (different chips, data Retention methods are also different), bad block addresses (like hard disks, Flash has bad blocks and must be blocked), and so on, the computer can correctly identify the USB flash drive. When the data is damaged, the computer cannot correctly identify the USB flash disk. Of course, sometimes it is artificial writing error data, such as when JS mass production U disk, change the flash capacity of 1 gb u disk to 8 GB, plug in the computer, the computer mistakenly thinks that the USB flash drive is 8 GB, which is the principle of JS manufacturing and resizing the disk.

After the computer correctly identifies the USB flash drive, the player also finds that PDT has other functions, which can be used to generate a USB flash drive for various special purposes. The partition function is commonly used, the 1 U disk into several mobile disk; boot function-enable U disk can simulate USB CD-ROM, USB-ZIP, this is currently the most used function, encryption function-specify a dedicated encryption partition.

The functions of the mass production software divide the application into two categories: USB Flash Disk Recovery (not data recovery, but underlying hardware information recovery ), the USB flash drive, which is unrecognizable by the computer due to damage to the underlying hardware information, is recognized by the computer again. It is like the restoration of the MP3 firmware .. So many people do not recognize the USB flash drive. This is what others call it for mass production. The second purpose is to simulate the USB-CDROM, this is the original djhcszdh said. Many people said that the mass production refers to the U disk to draw a dedicated space, simulation into a USB-CDROM, and then load their favorite ISO image, so maintenance and installation are more convenient than the use of the real disc. This is an advanced method of USB flash drive DIY. Now a lot of U disk support 3 drive 3 boot, that is, a U disk is divided into 3 areas, each area is simulated into a drive, like the author of The kingmax U-DRIVER 8g disk with sk6281 master, partitioning is divided into a USB-HDD, A USB-ZIP, A USB-CDROM, loading different boot images, choose the appropriate driver at startup to load the corresponding boot image, it is very convenient to include three different boot and shutdown disks.

To sum up, although mass production is a word, it refers to two different features-restoring a USB flash disk or DIY boot a USB flash disk. We can tell you what it means based on the actual situation.

It should be noted that the mass production software corresponds to the main control, and the main control of any type uses the mass production software. If the mass production software is selected incorrectly, the mass production software cannot be used or the mass production is incorrect. We 'd better use chipgenius to check the master control chip of the USB flash disk. If you have the conditions, we 'd better open the USB flash disk and check the master control model. Then download the corresponding production tools and relevant tutorials.

Basic mass production knowledge

1. What is a mass production tool?

Volume refers to the meaning of batch, that is, a mass production tool can produce a lot of U disks at a time, as long as you have enough USB holes.

The production tool is a low-layer software developed by the manufacturer for operating the USB flash drive master chip. Its function is as follows:

1) low-end USB flash drives

2) producing encrypted Disks

3) Partitions: Read-Only partitions can be produced and the USB flash drive media type (removabel and fixed) can be changed)

4) The amount of output USB-CDROM, which can be used to start the disc

The production tool can be abbreviated as the MP tool. For more details, it is the mass production tool, which represents a mass production tool and software.

2. Do USB flash drives made up of card readers generate CDROM?

No, maybe there will be such a card reader in the future.

3. Is mobile hard drive energy available?

Currently, this is not the case. The company is working on this. It is suggested that the annual meeting will be held.

If such a tool is used, sales of CD/DVD may be greatly reduced.

4. Can all USB flash drives be created in mass production?

Yes, it depends on whether there is a suitable mass production tool released. The master control vendors certainly do.

5. How to Determine the USB flash drive master?

1) Use the chipgenius software to detect

2) the most accurate method-disk Removal

6. What is the best production tool?

Almost all of them are not skilled.

7. What should I pay attention to when using mass production tools?

1) Don't be afraid. Make sure that the USB flash drive is not broken.

2) When there are also frequent errors in mass production, such as USB flash drives turning into 8 m, then proceed again.

8. The maximum amount of CD-ROM output can be big?

Different versions have different brands. My 4G icreate can generate more than 1 GB. Developers will not disclose this technical indicator.

Now some masters can produce DVDs, which can reach 4 GB.

9. Is the higher the production tool version, the better?

Not necessarily. Check whether your USB flash drive is supported.

10. What is the compatibility and speed of CDROM startup?

New motherboard almost all can, the old motherboard some USB-HDD or USB-ZIP are not good, but CDROM can; if the motherboard supports USB2.0 and open "high speed ", USB flash drives also support USB, which is fast to start. This is an example of how to install WINXP.

11. Why cannot different production tools be used in general?

The main difference is that the master control chips of different manufacturers all have their own confidential commands and functions, and they are not universal.

12. Why does some CDROM succeed after being started twice?

This involves BIOS content. Different BIOS processing conditions are different. We do not have such experts here. During crack Vista, such as Binbin, BIOS experts came forward to solve many problems. Of course, they are for award. As for AMI, there is no such public program. It would be nice to solve the problem of identifying usb cdrom from the BIOS level.

13. Where can I get the production tool?

1) from the U disk manufacturer's website, generally the master developer gives them the master.

2) download from the website of Digital Home. The update is fast and complete.

3) Search for networks, including networks and

4) call or send an email

14. Can MP3, MP4, and other devices be used as boot disks?

The hardware is almost the same. Generally can only do USB-HDD start

15. How can I use the remaining space after mass production is CDROM?

The remaining space is identified as an independent USB flash drive, which can be made into a Fixed Disk for Further partitioning, or a removable disk. The remaining space can be used for startup or as a general USB flash drive to store files.

16. Can the production tool run under Vista?

Currently, this is not acceptable. There will be various errors in Vista.

17. If the CDROM output by the test volume is successful?

After mass production is complete, a large number of people cannot start up with several machines. How can I determine whether it is successful? It's easy to use a virtual machine. when starting the machine, select CDROM to start it first. If it succeeds, there will be no problems with mass production.

18. A strange phenomenon (solved)

When you encounter a motherboard, there is no problem when usb cdrom is started for the first time, but the second time, it will not work and it will stop, saying there is no system. The solution is to reset usb cdrom to the first boot in the BIOS boot sequence and save the BIOS.

19. What should I do if I cannot use software to remedy the production failure?

Transient flash pin, restore to factory status!

Some solutions can be restored using corresponding tools.
