I needed to install a system on an old computer.
There was no CD-ROM in the computer, and it was not interesting to install my own, and for a long time I was interested in how to divide my 8 Gb flash drive into several sections. It was not possible to do this by conventional means, because after creation Windows partitions refused to see the second section. Found a description various methods installing additional drivers for the second partition, but this did not suit me, because. this needs to be installed on every PC you connect to for the first time.
Therefore, I decided to dedicate Saturday interesting business on the study of how flash drives are arranged.
I learned a lot about what chipsets are, what to do with a flash drive if it is not detected by the system, where to look for software recovery utilities, and how to put a flash drive into test mode by shorting the legs on the chip. But we will not delve into everything.
1) You need to find out the chipset manufacturer and values VID and PID.
This can be done by downloading and running the ChipGenius v3.0 utility
(be sure to write down or save the data that it will show, because in case of bad firmware, this will help you find the program you need)
2) Then go to the iFlash database page and enter VID or PID into the search bar.
We find which programs are designed to work with your flash drive. (my flash drive was with an SK6211 chip, and the SK6211_20090227_BA program came up to it)
3) If you have a different chip, not from skymedia, then you can not read further.
So:
a). Connect the flash drive to the USB port of the PC.
b). We launch SK6211_20090227_BA.exe
in). In the utility press --> Advanced-->in the window Password enter numbers 123456
and click on the Check button.
The windows will become active.
G). On the menu Code Bank ver. select the latest database. For some, the flash drive was defined in the program (it turned green, Ready) only after that.
e). Next - press Multi-Partition.
In this window: Upper left corner - tick Enable CD-ROM, if you need to split the rest of the CD-ROM, and split the part into 2 more sections (ie, make CD + flash + Flash), then move the slider - set the partition sizes.
Right top corner- put a tick Enable CD-Rom Booting(make the CD-ROM bootable) and set the path to the ISO image. The size of the CD-part is set automatically depending on the size of the image. I tried a 2.5 GB image, everything is fine.
e). Be sure to enter the parameter autorun counter- he is responsible for all the glitches associated with the disappearance of the flash CD after several downloads:
turns out autorun counter this is the number of times the flash CD will appear in the system.
If we write 10 (as stated in the instructions), then the flash CD will appear and work exactly 10 flash drive connections.
In order for the image to work indefinitely, you need to write 255 (==unlimited) in this field
source: http://www.mydigit.net/read.php?tid=58732&uid=35139
and). Lun0 and Lun1 are partitions that actually will be seen as a flash drive. If the engine (see above) was not touched, there will be a CD + 1 flash partition, otherwise - a CD and 2 flash drives (the volume of each depends on the position of the engine in the upper left corner).
Here we install:
format - ( Fat or Fat32)
section title - ( format label l).
The first Flash partition can be done - ( Fixed) (i.e. it will be defined not as a flash, but as an HDD),
and also block the partition from being overwritten - ( write protection), immediately writing to it necessary files, specifying the path to the folder with them (but I did not do this, because overwriting protection was not part of my needs).
Click OK and agree to the changes.
h). Further (in the previous window that appears after this, you can set VID and PID(if you want to change the name of the controller manufacturer and its type displayed in CHIP GENIUS - to determine the flash drive by the flashing utility in case of subsequent flashing it won't affect), Serial number flash drives (you can use any) and LED parameters ( LED) - flashing frequency and light intensity, parameter Curr leave equal 100 mA(It is better not to set more, as far as is known, this is the maximum current strength consumed by the USB flash drive).
It is better not to change all other parameters - I don’t know what they are responsible for.
and). Write down your profile name and click " Save" (save the profile), agree to the changes and close this window.
to). Firmware is only possible if the flash drive is in the database (see above).
In this case, it lights up green and it will be written " READY".
Select the profile we saved and click AUTO LLF(AUTO LowLevel Format).
flash drive flashes yellow BUSY"The overwriting process is in progress.
Its successful completion is indicated by the green color and " PASS". Congratulations!
Important Tips!!!
- If the color before starting the firmware (after selecting the last database of supported flash drives) is blue (NO Match) - then you are out of luck (the flash drive is not in the database), wait for the firmware update or look for it yourself, I found the right one the third time.
- If you need to overwrite a new image, be sure to first use the Recovery Disk utility (or the main utility to rewrite the controller firmware without creating a CD partition - clear the Enable CD-ROM and Enable CD-Rom Booting checkboxes, leave only the LUN0 (removeble) partition, and only then change it again, as you need, otherwise an error may occur when flashing)
Thanks for all the tips and tricks.
Domrachev Ivan,
AVP-720,
flashboot.ru website,
Chinese programmers who wrote programs for flashing.
For example, we used a Kingston DataTraveler 1Gb flash on a Phison PS2134 controller and the Phison UP13 UP14 UP12 V1.96 utility.
You can create additional partitions on almost any flash drive with other controllers using the appropriate utilities.
The utility allows you to create several options for flash partitions:
Mode 3 - standard mode. One partition - read/write;
Mode 4 - 2 sections. Floppy and standard drive;
Mode 7 - 2 sections. The system shows two independent flash drive;
Mode 8 - 2 sections. Hidden password-protected partition and standard drive;
Mode 14 - 3 sections. Standard storage, HDD (not visible in Windows XP) and CD partitions;
Mode 21 - 2 sections. Standard storage (read/write) and CD partition (read).
View of the flash from the side of the controller.
View from memory.
First you need to reflash the controller with standard settings. This is necessary if the flash already had a partition (hidden or CD-ROM).
If there were no additional sections, go to step 2.
Step 1.
Unpack the utility, for example, to the C:\Temp directory
Run ParamEdt-F1-v1.0.20.2.exe.
On the F1-PS223X tab, we don’t change anything, go to the F1-1 tab. Fill in the values as in the screenshot.
VID&PID - can be real or any value in 0x0000 format.
Fields Manufacturer, Product can be any. The value of Inquiry Revision is not changeable. By checking the Preformat checkbox we enable low-level formatting.
Set the values on the Controller tab as in the screenshot. Then save the settings Save As, for example PS2134_flash.ini
Close the configuration utility. Run F1_90_v196_00.exe and select the previously created file PS2134_flash.ini
We connect the flash to the computer. Click Start. The low-level formatting process will start.
Then a message will appear stating that formatting is complete.
We reconnect the flash, we are waiting for the definition of the flash in the system. The flash will be defined as USB DISK 28X USB Device.
The LED will flash intermittently during this time. Now click OK.
Formatting completed successfully.
Reconnect flash. Formatting with standard Windows tools.
Step 2
Create an additional CD-ROM partition.
Run ParamEdt-F1-v1.0.20.2.exe
Go to the F1-1 tab. Fill in the values as in the screenshot. Please note that the mode is set Mode 21 and take down the flag Preformat.
On the F1-2 tab, select the CD image, for example, select Windows image xp.
Set the values on the Controller tab as in the screenshot. Then we save the settings Save As under a name such as PS2134_flash_cd.ini
Run F1_90_v196_00.exe, select the created ini file PS2134_flash_cd.ini
Click Start. The process of testing and recording the image will start.
Format it, HPUSBDisk will do
Is it possible to format a flash drive in NTFS. As you know, the reliability and fault tolerance of the NTFS file system is beyond praise, see ...
How to format a flash drive in CDFS / UDF format?
The Compact Disc File System (CDFS) is. So it's hardly possible.
And unsubscribed - how to completely format the USB flash drive along with the CDFS partition, as well as ... the disk number of the USB flash drive, then you can format one of your other disks.
Give me an answer first. Why did such a question arise?
With the help of what program mono format a USB flash drive under CDFS?
CDFS is file system CDs, so I don't think so... than FAT does not suit?
Actually - tell me, please, how to make a flash drive ... ps. Source FS - CDFS zy. Can you elaborate on everything? I have never done this, I don’t know anything.
Secondly:
Let's start creating a bootable flash drive:
1. Unpack the archive
2. In the "USB_PREP8" folder, run usb_prep8.cmd. Press any key. In the "PeToUSB" window that appears, click "Start", nothing to me (just select your flash drive / SD card from the drop-down list). After formatting the flash drive (SD card), close only the "PeToUSB" window. Do not touch the "USB_PREP8" window.
3. Run command line, in it go to the folder where "Bootsect.exe" is located.
4. After you have reached the directory of the "Bootsect" program, write on the command line
bootsect.exe /nt52 X:
where X: is the letter of the flash drive. Note: during this operation, all windows / programs that display / work with a flash drive must be disabled. If everything went well, then the message "Bootcode was successfully updated on all targeted volumes" will appear in the window. Press any key.
5. Return to the window with "USB_PREP8", items marked with numbers should appear there, there is nothing complicated about this, here's what you need to do:
I. press 1 then Enter to select the installation directory Windows files, it must be a disk in the drive, or a mounted disk image (if there are no necessary files in the selected directory, the corresponding inscription will appear, repeat the step again);
II. press 2 and Enter and enter one letter of the Latin alphabet that does not correspond to any media on your computer (for example, W);
III. press 3 and Enter and write the drive letter of your flash drive;
IV. press 4 and Enter, this will start the process of creating a bootable USB flash drive;
This is just for booting from BIOS. CDFS won't start from BIOS.
What is needed for this:
1. USB Flash Drive >=1Gb
2. Windows disk or image
3. USB_PREP8, PeToUsb, Bootsect.exe (rar, 450Kb) http://5an.kz/flash.rar
Help with formatting
It is not formatted.
This is more likely not a virus .... your antivirus swears at the crack for the game
CD (and DVD) discs are not formatted. If the disc is a one-time use, just throw it away, and if it is rewritable, then select the "Empty Disk" operation in the disc burning program.
The antivirus swears at autorun, turn it off temporarily, install the game, and only then turn on the antivirus protection and don't worry about playing.
Help solve the problem: There is a flash drive (given by the boss), it is with the CDFS file system, is it possible to somehow convert it to FAT32
Good program for formatting flash drives HPUSBFW
The trick is that it is divided into two parts - the first computer is seen as a real CD-ROM, with the cdfs and readonly file system somewhere around 114 mb, and the remaining 11 can be formatted as a regular disk.
Flash drive in CDFS file system???
You are confusing something, dear.
The CDFS file system is a relatively simple format that was defined in 1988 as a read-only formatting standard for CD-ROM media.
What does the CD - DVD (that is, the drive) have to do with a flash drive ??
Please note that when formatting, all information will be deleted! And you can format without any extraneous programs in PAN. MANAGEMENT- ADMINISTRATION-COMP. -UPR.

RAW file system
Look at what you are recording, maybe RAW is in the settings
Format the flash drive first using the HDD Low Level Format Tool, and then use the HP USB Disk Storage Format Tool. Download links above...
The RAW file system is a type of file system (FS) of a logical disk determined by the operating system (and other programs) in case of partial destruction in the FS structure, such as FAT or NTFS, for example.
As a rule, this happens in the process of any failures of the operating system, the operation of various kinds of programs, incorrect termination Windows work or working with a flash drive, as well as the consequences of a virus attack. Then, when accessing the disk, a message appears asking you to format it.
The following main failures can be identified:
- incorrect values of the geometry of the logical partition in the partition table;
- partial destruction in boot sector file system;
- destruction in the area of the main file table MFT.
P.S: If you are faced with a situation where operating system detects a RAW FILE SYSTEM on your media, you can either try to recover the RAW file system yourself, or contact a specialized data recovery company.

How to format a flash drive - 5 ways. To improve the performance of the flash drive and adjust it to your needs, you need to format it.
Looks like the file system has crashed. Format to FAT32 or NTFS so that the computer can see it. Drop it, put it in. It is possible to be perverted still with CDFS to try.

USB Flash can be used not only in the traditional way "like a big floppy disk". There are more interesting and in some cases more useful options. This article will describe how to make a USB CD-ROM from a flash drive. Of course, the flash drive will remain a flash drive, but the computer will "see" it as a CD-ROM.
Such a trick may be needed, for example, in order to install Windows XP or 7 on a computer without CD-DVD drive. Of course, in such a case, there are other ways, but such a CD-ROM flash drive allows you to install Windows on a netbook without any problems and any extra gestures.
If you need to do installation flash drive Windows 7 there is another way, easier - Installing Windows 7 from a USB flash drive.
The first thing to do is to get the disk image as a file in ISO format. This can be an image of the Windows XP installation disk or any other CD or DVD disc. There are many programs that allow you to save content laser disc as an ISO file. For example, such as UltraISO, InfraRecorder, ImgBurn and many others.
Then, you need to find out exactly which controller is used in your flash drive. The fact is that even in the same model of flash drives there can be different controllers, and the programs with which you can make a CD-ROM from a flash drive are rigidly tied to the controllers, that is, each controller has its own program.
The most accurate results are given by the usbflashinfo program, by itself it gives out "crakozyabry", but they need to be sent to the author and he will send information about the controller of your flash drive. You can search for your model among the ready-made results in this forum.
After that, on the site flashboot.ru, find a program to work with the controller of your flash drive. Through this program, create a CD-ROM partition on a flash drive and upload your ISO file there.
The following will describe how to create a USB CD-ROM from an Apacer AH325 4 Gb flash drive. This flash drive uses a Phison 2251-60 controller. Programs for working with this controller are called Phison_MPALL. They come in different versions. This article will use version 3.20.0B2 as an example.
First you need to make sure that the usbflashinfo program did not make a mistake and that Phison is really inside, for this you need to run GetInfo.exe and enter the drive letter under which your flash drive was defined in Windows, and then click the "Read" button:
If there is a Phison controller inside the flash drive, then the program will display information about the flash drive:
The next step is to create configuration file for subsequent recording of the flash drive. To do this, run the MPParamEdit_F1.exe program:
and then specify the necessary options in it starting from the top, in the "CD-Rom Image" field you need to specify the path to the file and the ISO file itself:
Note.
It is possible to create two partitions on a flash drive, one will emulate a CD-ROM, and the second partition will regular flash drive or emulate a hard drive. In this case, the CD-ROM partition will be allocated as much as necessary for recording ISO image, and the rest of the space on the flash drive will be allocated to the removable/fixed HDD partition. However, if the flash drive will be used for booting and especially for installing Windows, I advise you to make only one partition - CD-ROM. You will "lose" part of the total capacity of the flash drive, but you will avoid compatibility problems on different versions BIOS.
In this program, you need to open the file that was created in the settings editor. If all the fields of the program are empty, then you need to click the "Update" button, after which an entry about your flash drive should appear in one of the fields. After that, you need to press the "Start" button and wait for the program to work:
The green color of the field means that everything is finished. You need to close the program, and then open the manager Windows processes(taskmgr.exe) and manually kill the MPALL program in it. The fact is that after closing the program window, its process remains in memory.
Now you can disconnect the flash drive through the "Safely Remove Devices" and pull it out of the USB connector. Then plug it back into the connector - but now Windows will detect it as a CD drive.
