What if the flash drive is not detected?
We are all used to the idea that revolutions are somethingmeaningful, which, by definition, can not go unnoticed. But that's exactly what happened in the field of computer technology: very few time passed between the first messages on the forums about compact storage devices and the massive appearance of affordable flash drives. Perhaps the regulars of computer stores watched this process personally, but for most computer owners it was "like snow on my head". Some still can not realize that the CDs that served by faith and truth, in fact, are experiencing their sunset.
Talk about the benefits of flash drives can be a long time. This is, indeed, a breakthrough in the field of information storage technologies. It's even more surprising to see once that the operating system does not display a USB flash drive working normally. Everything happens as usual: a USB flash drive is inserted into the free USB port ... and something unusual happens. There are two options for further developments. The first - the flash drive is not detected. There is a sound signaling the connection, but the Windows system happily reports that the USB device can not be recognized. Accordingly, no drive letter appears. The second - the letter is assigned, but the explorer does not open the USB flash drive. It looks like it's working with a blank CD. The approach to recovery is identical, so we will not distinguish "symptoms". Further user actions depend on the availability of free time and the desire to restore the performance of the USB flash drive. All can be divided into three groups. If the flash drive is not detected, then the representatives of the first group get a new, good, the prices for flash drives are falling every day. Users of the second group try to restore the device in standard ways and if the result is negative, they also buy a new one. Well and the third do their best. By the way, the expression "flash drive is not determined" and "device place in the trash can" are not identical. In 90% of cases it is possible to return the flash drive to life.
So, consider the order of actions. First of all, if the flash drive is seen by the system, you can try to format it. To do this, open the "My Computer", on the letter of the flash drive we press the right mouse button and follow in the "Formatting". It remains only to run it. If it does not help, then try the special program HP USB Format Tool. If the result is negative, it remains to resort to flashing the microcontroller built into the device. He manages the work of the flash drive and requires careful handling. For example, the safe extraction function of the device is not in vain integrated by Microsoft into its system, and its ignoring just leads to such results. Forgot to close the cap? Static electricity does not sleep!
So, the flash drive is not detected. With the help of the program CheckUDisk we define PID, VID and Vendor. After that on the Russian site flashboot on the obtained data we search for the necessary file in the base iFlash. In the resulting list, select the model you want (if it is not, then we are guided by PID and VID), copy the name to the buffer from the "Utility" column and in the "Files" section we search for the copied name. In the downloaded archive there is always a detailed instruction for recovery. Careful adherence to it almost certainly guarantees the restoration of the device's performance.
Sometimes it is not possible to find the values of PID and VIDit is possible: when you run the program CheckUDisk nothing happens. The process is in memory, loads the CPU, but does not display any messages. In this case, you can use alternative software solutions, such as ChipGenius or UsbIDCheck.
After the flashing has been completed, you can try using the appropriate programs to restore some of the information on the flash drive.
A few tips: if the flash drive is heated, then the chances of recovering it are small - in garbage. Before formatting or reflashing, you should try to connect it to another USB connector.
