u盘恢复工具（U disk recovery tools）

u盘恢复工具（U disk recovery tools） u盘恢复工具(U disk recovery tools) U disk repair tool Different from the U disk format tool, also known as production tools of production tools, mainly using chipgenius detection of U disk main control chip, and then download the corresponding production tool and the corresponding tutorial, the Internet has a lot of friends have successful experience, as long as the main control chip of U disk, the method is the same but the best is recommended. With the main control chip, with the capacity of different capacity I have not tested. U disk repair tool (PortFree Production Program) [1] finally made after the success of the U disk to form two separate parts, the first part is a read-only mode, the contents can not be removed by the common format, the content of the second part of the normal or U disk form. This one is the biggest advantage of the first part will not be affected by the virus, only the infestation, but also U disk guide (guide function main function is to have a disc image to boot), the startup mode and ordinary boot disk boot mode, making the U disk boot method online success rate is much higher than common U disk boot. I have already said, online common U disk boot mode is finally write the data in the normal reading and writing part. Instead of in a read-only mode. The read-only mode depends on the size of the production tools used in the production of CD image size. Edit the U disk repair tool set in this section U disk repair tools commonly used are: PPP (professional U disk repair tool) v3.27, Mformat (U disk repair tool) V1.0 Chinese version, PortFree Production Program (U disk repair tool) v3.27 Chinese version, universal U disk repair tools, Kingston disk repair tool etc.. Edit this section U disk repair instructions 1, only for the U disk formatting error to repair, can not repair the physical damage to the U disk. 2, only when the U disk can not be used normally, you can try to repair, in general, do not often use. [2] Edit this paragraph U disk repair skills At present, the use of U disk is very common, and people often use U disk to backup, carry and transfer files. However, if the U disk from port USB pull out before, forget the uninstall uninstall * *, or not completely, or due to incorrect operation, and directly to the U disk from USB mouth pulled out, there may cause damage to the U disk, sometimes leading to the computer can identify the U disk. If you haven't had any experience dealing with this situation before, you'll probably think that the U disk is no longer available and should be thrown into the bin, but it's too bad. Is there any way to restore the functionality of the U disk? The answer is yes, can be carried out in accordance with the following steps: open the control panel, management tools, management, computer storage, disk management, will appear as map interface, text in "disk 1" right click, select "initialize the disk", directly click ok". When initialization is complete, the status of the U disk becomes "online" state. Note that the lock on the U disk is open at this time, otherwise the following prompt will appear: "because the media is protected by writing, the requested" * "cannot be completed." Right click on the right side of the white box, select "new partition", enter the New Partition Wizard, click next, select the partition type (primary partitions, extended partition or logical drive), generally choose the primary disk partitions can be. (Note: the following dialog box will appear in sequence, so the screen copy is not here.) Next - select disk space capacity: generally use the default size. Next - assign a drive letter (or not). The next step - select the following settings format this partition settings form (file system type, allocation unit size, volume) (do not use fast format). Next - complete the formatting wizard successfully. Click Finish to wait for formatting to complete. When the formatting is complete, the U disk status is displayed as "in good condition", that is, done. This repair method can generally restore the U disk. However, there is a drawback to this method of repair, that is, it can not restore the original data on the U disk (all data is lost!!!). This method is relatively useful if the original data on the U disk is not very important. Edit this paragraph common U disk repair case 1.U disk, please insert the disk into the drive solution When a colleague brings an U disk and inserts the USB socket, the U disk indicator lights up and displays the disk symbol on my computer. However, when you double-click it, a prompt appears: "insert the disk into the drive.". The same hints appear when formatting this disk. Be nonplussed over sth. Efforts to seek solutions to solve methods are as follows: 1, right click my computer, storage management: - Disk Manager, in the right side of the interface can be seen on the logo, on behalf of the flash and click on it, select a partition, format and follow the prompts to complete the operation, is expected to solve the problem. 2. Download low-level formatting tools to format low-level flash memory. U disk repair tool (PortFree Production Program 3.27) usage: (1) click on the lower right corner of the software "OPTION", the window will appear as follows. (2) select the "Others", select "Type" - > "Removable" (3) select the "Capacity Adjust", select the U disk capacity you here; if you don't want the capacity here, please click the "ADD", you fill in the required capacity. (4) select the "Flash Test", select "Low Level Format"; there are two parameters, one is the All Blocks (which means low formatting of the entire disk), another is Good Blocks (it means only low formatted blocks, the parameters for the U disk containing bad area) (5) after all in accordance with the above methods, please click "OK" to save the settings, and then U disk to your computer, click the "RUN" format, low start. The two methods seem to work well, but they are not good enough when applied to this U disk. 1, on the right side of the interface part can not see the sign of the flash, the lower half store but not in vain; 2, click, click "RUN" after my computer U disk drive U disk disappeared, the lights do not flash, low-level formatting cannot be completed. 2.U disk access to the computer without any reflection There is a customer request for U disk data recovery capacity of 256M, when customers take the U disk access to the computer without any reflection! Step about the U disk data is about 80M, inform the customer every M data recovery 100 yuan, because of the internal CAD for engineering drawings is very important so the customer is very readily agreed, the Engineer in accordance with the following ideas were resolved: 1, open the U disk for package development, customer requirements as long as the data. So the shell does not need to consider, after opening the master now using the I5062 scheme as follows: (1): VCC main power supply voltage check (normal VCC=3V power supply is the key whether the working voltage of U disc) (2): by measuring the clock oscillator clock ends with voltage of about 0.8V, the preliminary judgment of the clock circuit is normal, the substitution replaced crystal fault still (clock signal is necessary to master work) (3): communication through measuring the two points above, preliminary judgment power and clock are normal, the main To check the communication line is normal, check the D+ and D- to the main control line is normal! (4) through the above measurements, we can make a preliminary judgment that all the work conditions of the master control are complete, and the rest is the master control problem. I believe everyone will replace the control to achieve the purpose of data recovery, but we have many years of experience tell you wrong, because the internal U disk main control chip control procedures, when replacing a new master is not identified in control of FLASH, must through the production tool initialization can, but it will damage the internal self stored data on FLASH! Based on our years of experience, The main damage mostly because of the internal DC-DC converter leakage, the main control of the internal power supply voltage caused by low does not work, the solution is as follows: U disk 3V voltage regulator tube removed, in its 3V output end is connected with an external adjustable power supply is adjusted to 3V voltage to each 0.1V system adjustable high voltage, when the U disk can properly identify the stop voltage, so you can put U disk data read out. The principle is that because the main internal DC-DC converter leakage, so that the normal VCC=3V voltage can not meet the main control work, then it can artificially adjust its supply voltage to compensate for leakage losses! When I transfer the voltage to 3.4V, the computer can identify correctly, and quickly copy and save the data in the U disk. 800 yuan has been gained. Simple, ha ha, technology is the primary productive force! 3. format the U disk, please A client for U disk, internal financial statements, due to excessive maintenance no one dare to take this live, so the direct customer offer 1000 yuan, the overall requirements for data recovery, U disk phenomenon can recognize the dish, but the open suggested "please format the disk U"! For sub problems, I believe we all feel very difficult, because you can completely judge the U disk hardware problems, mostly software problems, but can not be formatted on the U disk, what should I do? Specific solution: our engineers put the U disc FLASH removed to protect the data, reload a same FLASH, still need to format the prompt access to the computer, because no new data in the FLASH format, can access the data, but replace the data of FLASH will be prompted to format, so we the method is not installed FLASH U disk access to the computer system, suggesting that the U disk format, see the formatted capacity of 16KB itself in the property, load FLASH data to access the computer system to not prompt successfully read the internal data format! Repair completed,
