A few ways to fix the USB stick

The USB flash drive failed to format due to various reasons, such as "Windows cannot finish formatting". But this does not mean that the U disk will be discarded, try the following methods (but for the people who do not play the computer is a bit difficult ha):

Method One:

1. Point start-run-input Cmd-format f:/fs:fat32 (here F: refers to the drive letter of the USB stick)

2. Open Control Panel-Administrative Tools-Computer Management-Disk Management-Find the drive letter where the USB flash drive is located--right click--delete the disk partition (this option is gray, no way to choose)-Create a new disk partition-follow the prompts to complete the disk partition and then format the USB flash drive.

Method Two:

Download the Usboot tool (this tool is a classic ghost system disk with a large search on the Internet), using HDD format, which needs to follow the instructions to unplug and then insert the USB stick, and finally complete the boot disk production. At this point, you can double-click the drive letter to indicate if formatting is required ... Then click "Yes", finally see the long-Lost Format window, choose Fat format, everything goes smoothly, after completion, the USB stick can be used again, capacity without loss. Friends who have the same problem can try this way, of course, the situation of the USB stick cannot be formatted is very diverse, as long as it is not flawed, there is always a way to solve. Hope to be useful to everyone.

Method Three:

To the manufacturer of a USB flash drive chip corresponding to the production tool software (or online search and download), the use of production tools software format

Open the U disk, found that the chip is written "CBM2091", so in the online search "CBM2091", to find cbm2090cbm2091 production tools, run can detect the U disk, in the Flash disk settings, the scanning mode is set to low-level scanning, and check the need to format, need to aging, OK after select all start, so began to scan, format the U disk, look at the flash drive constantly, know that repair is no problem.

Method Four: (it is said that many people have succeeded in this way)

Find a ghost file of the right size, (or you can now do a. gho file), the size of the building is how big, ten or twenty M chant, and then use Ghost forcibly to the U disk to recover data, is Ghost "disk" –> "from image".

Attached: U disk mass production tools and related knowledge detailed

First article on production tools

1. What is a mass production tool and what is the role?

Volume refers to the meaning of batch, that is, the production tool can produce a lot of u disk, as long as your USB hole enough.

The production tool is a low-level software developed by the manufacturer for the operation of the main control chip of the U disk, and the role:

1) Low-grid u disk

2) Production of encryption disk

3) partition, can produce read-only partition, change USB drive media type (Removabel and fixed)

4) Volume output Usb-cdrom, this action can be done to start the disc.

2. Card reader composed of the U disk energy output CDROM?

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

3. Mobile HDD energy production?

At present, the core State is engaged, it is said next year will come out.

If such a tool is really coming out, Cddvd sales may be going down significantly.

4. Are all USB drives energy-producing?

It should be, to see if there is a suitable mass production tool to release. The main control companies must have.

5. How to determine the main control of U disk

1) The most accurate method-to remove the disk

2) According to the software vid & PID combination of known USB manufacturers list to judge the master. But the vid & PID can be changed at will, for inferior flash memory USB stick may not be allowed, also can use VMware to judge. See related posts.

6. What production tools are good

All the same, just look familiar and not proficient.

7. What to pay attention to using the mass production tool

1) do not be afraid, bold, u disk will not be bad, if there is scrap, please sell me low price, I accept.

2) Mass production also has a frequent error, such as the U disk becomes 8M, the same 1), again.

8. What can be the maximum number of CD-ROM output

Different versions, the brand is not the same, my 4G icreate can output 1G more points. This technical indicator developer does not disclose.

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

Not necessarily, it depends on the type of USB stick that supports you.

10. What is the CDROM start-up compatibility and speed of volume output?

The new motherboard almost can, old motherboard some HDD or zip is not possible, but CDROM can; if the motherboard supports USB2.0 and the "high speed" is turned on, the USB flash drive also supports USB2.0 this start-up is fast and is used to install XP as an example.

11. Why are different mass production tools not universal

The main difference is that the different manufacturers of the main control chip has its secret instructions and functions, can not be universal.

12. Why do some cdrom have to start 2 times before they can succeed

This, please have a master study

Speaking of this, the BIOS is involved in the content, different BIOS processing situation is not the same, we do not have such experts here. When Binbin and other crack Vista, the BIOS experts came forward to solve a lot of problems, of course, for the award, as for the AMI, there is no such public procedures. It would be nice to solve the problem of usbcdrom recognition from the BIOS level.

13. Where to get the mass production tool

1) from the U disk manufacturer's website, the general master control developers have given them the master control.

2) from the main control developer website.

3) search, including the web and here

4) Call or email to

MP3, MP4 and other equipment can make boot disk?

Hardware basically almost, all can.

15. How to use the remaining space after mass production into CDROM?

The remaining space will be recognized as a separate USB stick, which can be made into a fixed disk, further partitioned, or a removable disk. The remaining space can be used to start, or as a normal U disk storage files.

16. Can the production tools run under Vista?

Currently, there are a variety of errors under Vista.

17. What if the CDROM of the test volume output is successful?

A lot of people in mass production after the completion of a few machines can not be started, how to determine whether successful? very simple, with the virtual machine, the choice of CDROM first start on it, if the success of the production is not a problem.

18. A strange phenomenon (resolved)

Encountered a motherboard, the first usbcdrom boot no problem, but the second time, it is not, stopped, said what no system. The workaround is to reset the Usbcdrom to the first boot in the boot order of the BIOS and save the BIOS.

19. What if the mass production fails and cannot be remedied with software?

Short lead pin, restore to the factory status, related methods check my post.

The second USB drive starts

1. There are several ways to start a USB stick

There are currently several:

1) CDROM mode, this to use the production tools, start the compatibility of higher

2) HDD mode, the use rate is also high

3) Zip way, this looks like it's going to be eliminated.

4) FDD mode, this basic elimination

2. High success rate for which mode of start-up

As above, basically 1) > 2) > 3)

3. HDD mode or Zip mode to start PE, there are several methods

1) Ntldr+grldr

2) GRUB installed to MBR

3) Dos+grldr

4) LINUX (ETC) +grldr

5) NTLDR installed to MBR

2nd and 5th are recommended, with high success rates

4. Is the USB stick boot compatibility poor?

This is a misunderstanding, for the older motherboard, because of the BIOS and boot speed issues, the most critical is the standard does not unify the problem, startup is difficult, but the new motherboard, basic can be started with CDROM or HDD mode, and directly support USB2.0 Therefore, the installation system and so very fast.

5. What should you pay attention to when booting USB?

Carefully check your motherboard BIOS settings, whether the USB drive is set correctly for the first boot.

Some motherboards, the USB option has the "Full speed" and "high" points, to open the latter, so fast.

For CDROM and Hdd/zip dual-boot, if the motherboard does not recognize the HDD or ZIP, the grldr on the CDROM is also not available for HDD search.

Generally the main identification of CDROM or HDD, can start success.

6. What are the benefits of the USB flash drive production into CDROM mode?

This, all understand, CDROM standard unification, start success rate high, of course file is also safe. It is also critical that XP can be installed.

7. How slow the speed of the U disk

I am also solving this, but I found that my volume of output HDD can be changed quickly if it is resized by HDD.

8. What format should I use to move the hard disk?

Mobile hard disk should use HDD format, XP format and then set the main partition of mobile hard disk as activity

10. When the CDROM is started using the mass production tool, can the other USB drive partition be enabled?

Yes, you can use HPUSBFW, flashboot and other USB drives to start the format tool to achieve

11. Why does the USB flash drive load mirroring for a long time?

The time it takes for the PE mirror to load depends on your motherboard, and some motherboards take seven or eight minutes to load the image, perhaps dozens of seconds on the motherboard that supports USB2.0 boot

12. Can boot from USB stick, why can't mobile drive start

First verify that your mobile hard drive already has a PE file, and that the primary partition of the removable hard drive is activated (using PTDD to rebuild the MBR or perform fdisk/mbr),

Then in the case of plugging in the hard drive, open the hard drive entry in the BIOS, there should be two hard drives, the mobile hard drive up to the first bit (the default is the second bit).

The third USB Stick Hardware Foundation

1. What are the hardware components of U disk?

Master Chip + memory chip

The master chip stores information that controls the flash. Some USB stick is broken, by changing the main control, the content is not lost, as long as the flash is not bad.

Flash, is a foreign devil out of the current in China, the vast variety of u disk is mostly eliminated from the poor quality of flash memory made, so easy bad.

2. The main control has several

CBM (Chipsbank), Icreate, Guo, sandiks etc ....

3. A few of the flash beings

It is divided into SLC and MLC from storage, the latter is larger than the former, but the speed and life are shorter than the former.

Fourth DOS disk software &usb2.0 driver

1. What should I pay attention to when cloning software on disk partition?

If the motherboard BIOS does not recognize the output CDROM after the USB flash drive, Ghost and PQ and other software is not recognized, and therefore cannot be used.

2. How can I assign a drive letter to the HDD portion of a U disk that cdrom?

The new motherboard identifies the first partition of the USB drive HDD, so this part does not need to be driven.

For unrecognized, it can be resolved by loading Panasonic's Usbaspi.sys and Aspidisk.sys in Config.sys.

3. Why is a drive lost after loading Usbaspi.sys?

This is because the drive resets the USB device, and the contents of the IMG file on Usbcdrom are not available, and the solution is to load the IMG into memory, using the Grub4dos or Isolinux software.

4. What should I pay attention to when loading the USB2.0 driver?

Primarily compatibility issues, some motherboards may not be able to run grub4dos, some may not be able to load usbaspi.sys and so on, the solution is to try to use Iomega or Duse drivers.

5. How do I load drivers for usbcdrom?

This is a long-standing problem, I tried Panasonic Usbcd.sys (premise is to load Usbaspi.sys) regardless of use, tried the "Universal Drive" Eltorito.sys, the same can not, but this may be a case, or motherboard problems.

In my new version of "Peach Red PE" included these two batch names are Usbcd1.bat and Usbcd2.bat respectively.
