Question: U disk space to 0, who is no better data recovery tool? (Note: not a virus)
best answer:
in turn open the Control Panel, Administrative Tools, Computer Management, storage, disk management, there will be a figure of the interface, the text " Disk 1 "on the right-click, choose" initialize disk ", directly click" OK. " Initialization is completed, U disk state into the "online" state.
attention at this time to U disk lock is turned on, otherwise it will appear the following prompt: "As the media by the write protection can not be completed required * to make."
the right The white box on the right-click, select "New Partition" to enter the New Partition Wizard, direct click Next, select the partition type (primary partition, extended partition or logical drive), you can usually select the main disk partition . (Note: the following dialog box appears in order, so do not give here a copy of their screen.)
Next - Select the disk space capacity: the general use of the default size. The next step - assign a drive letter (or not assign).
Next - Select "according to the following settings to format this partition" to set the form of formatted (file system type, allocation unit size, label) (do not select Quick Format).
Next - the successful completion of formatting wizard. Click Finish to complete you can wait for its format. Formatting is complete, U disk status shows as "good condition", that you're done.
this repair method can be generally U disk recovery. However, this repair method also has a disadvantage that can not recover the original U disk data (data are lost !!!)。 U disk if the original data is not very important, this method compare.
Annex 2: u disk drive Fault
U ~ Please disk into drive ~ related issues
Failure: The U tray transfer into the data, change the drive letter caused.
failure phenomena: Windows XP SP2 OS, U disk to Thunis OEM
1, insert U after-hours, "My Computer" to display the "Removable Disk (H:) ", but" double-click the "Display" Please insert the disk drives (H:) "
2, see the" Removable Disk (H:) "property," used space " and "free space" are 0 bytes
3, directly right "format", it says "no disk drive H Please insert a disk, and then try again"
4, in the "Computer Management" and "disk management", see above letter "H:", below you can see the "Removable Disk 1 No Media"
5 , re-install the driver, suggesting that "the wizard can not find your hardware than you have now installed the software more matching software"
6, with ManageX tool repair, the corresponding "format" and other features selected Gray items are not available; with Iformat tool format, the system can not recognize USB devices available
attached 3: U disk appears "Please insert the disk drive" approach
< br /> a friend sent the U disk bad new: the reason is unknown.
friends then to send back all the U disk. connected to the host before the first look at the system correctly identified by my computer after a "Removable Disk", but double-click the drive letter U to the surprise of a "Please insert the disk drive I" prompt, view the properties of U disk capacity was 0 (Figure: failure phenomenon). then try to format it, try a bit lower in the system, or prompted to "drive I in no disk. Please insert a disk, and then try again ": (. no alternative, downloading several U disk formatting tools, hey ~ still the same: (. Could it be interface issues: q: but the friend have tried using several machines, or holding Xiao Xing's mental Try it, change to the machine fro the USB interface, but the fault has not been solved. I thought the new U-disk is broken: q: (will not be so " flow "it: w:). was to find an empty one claiming to be U Disk Tools" EraseTools2.1 ", clear thinking and hard disk tool is the same principle it should be, the dawn finally appeared. software is simple to use (Figure: Clear tool), as long as connected to the U after-hours to install the software (if not connected to the U drive is not installed), run the software, then click "Start", click the YES button, the program can be U disk automatic recovery initialization state. The results of a test under, haha ~ U disk is risen (Figure: failure to lift). things have been resolved ...
Annex 4: U disk Please insert the disk drive solution
colleagues brought a U disk, insert after the USB jack, U disk indicator light, and my computer also shows the disk symbol, double-click it, but when prompted: Please Insert the disk drive. this disk is formatted the same when the prompt appears. a difficult jobs development.
efforts to find a solution, the solution is as follows:
1, right click My Computer, Management - Storage - Disk Manager, the interface in the right you can see a sign on behalf of the memory, click on it, select "Create a new partition", according to prompts to complete the formatting and other operations, the problem can be hope to solve.
2, download the "Star Shuttle low-level formatting tools," low-level format on flash memory.
U disk repair tool (PortFree Production Program 3.27) to use :
(1) Click the lower right corner of the software "OPTION", will appear the following window.
(2) Select "Others", select "Type" -> "Removable"
(3) Select "Capacity Adjust", here select your U disk capacity; if you want here is not the capacity, please click the "ADD", fill in your required capacity.
(4) Select "Flash Test", select "Low Level Format"; There are two parameters, one is All Blocks (it means low-format the entire disk) the other is Good Blocks (it means only low-formatted block, this parameter contains a bad area for U-disk)
(5) are good choices in accordance with the above method, after Please click "OK", save the settings, then U disk connected to your computer, click "RUN", start low format.
the two approaches, it seems very easy to use, but applied to the U disk that is not good when used.
1, upper right side of the interface can not see a sign on behalf of flash memory, lower part but can not hit stores, in vain;
2, press the "RUN" after my computer disk drive letter missing U, U disk of light does not flash, and low-level format can not be completed.
attached 5:
come across a lot of people called for data recovery clients, but he was not a clear way, following the example of the U disk to data recovery methods to explain several specific:
Case 1: there is a customer of the U disk data recovery capacity of 256M,, U disk access when customers bring any computer to reflect!
tray further asked about the amount of data U In the 80M or so, to advise customers of each of M data recovery 100, as used in engineering within the CAD drawing is very important so customers very readily agreed, thinking engineers conducted according to the following address:
1, split open U disk is encapsulated by one, the customer requirements as long as the data, so do not consider the case, apart and use the I5062 program against the current master as follows:
(1) Power Supply: Check main supply VCC normal power voltage (VCC = 3V power supply is the U disk is the key to the voltage)
(2) Clock: When Zhong Jingzhen by measuring around two feet with 0.8V voltage, the initial normal clock circuit judge using the substitution method is still replace crystal failure (master clock signal is a necessary condition of work)
(3) Communications: more than two points on the measurement of power supply and clock are preliminary judge normal, mainly the communication line is normal, check the D and D-lines are normal to the master!
(4) through the above points of measurement, can initially determine the working conditions of all the available host The remaining problem is the master. I believe we will replace the master to achieve the purpose of data recovery, but our years of experience tell you is wrong, because the main chip U Pan internal control procedures, when to replace an Xin The master is not the time to identify FLASH control, must be made through the production of the early tools can, but that it will be low-cell destruction of internal FLASH storage of data! based on our years of experience, master damage mostly because of the internal DC-DC converter leakage, to the internal power supply voltage and low on the master does not work caused by the situation, the solution is as follows: the U disk removed to 3V regulator, in its termination an external 3V output adjustable voltage power supply adjusted to 3V to 0.1V for ways to increase each voltage, when the U disk can be properly identified when the stop raising voltage, so the U disk, data can be read out. principle is to the Lord control the internal DC-DC converter leakage, so that the normal VCC = 3V voltage does not meet the master work, then you can artificially adjust its supply voltage to compensate for leakage losses! if I transferred to 3.4V voltage computer can correctly identify the time rapidly within the U disk to copy the data stored, 800 hand, and a simple bar, Oh, technology is the primary productive force right enough!
Case 2: A customer brought U disk, internal financial statements, due to home maintenance department too much no one dared to take this live, so customers directly to offer for 1000 yuan, the overall requirements for data recovery, U 盘 phenomenon can be considered for the plate, but when prompted to open the "Please format the disk U "! for the second question I believe we all feel very difficult, because you can completely determine U disk hardware no problem, most are software issues, but not on the U disk format, how do? specific solutions: First of all, our engineers FLASH to remove U disk to protect data, re-load a different type of FLASH, access to computer and still prompted to format because there is no data in the new-for-FLASH, the normal access to the data can be formatted, but replaced with FLASH will be prompted for the data format, so our approach is, do not install FLASH U disk access to the computer, the system prompts to format on the disk itself is formatted U see in the properties of capacity 16KB, into a data FLASH, access computer, the system does not prompt to format the internal data read out smoothly! repairs are completed,
