1, may be the U disk virus In this case, the likelihood of the virus is very high, so first ghost Win7 system user to check their own USB stick device security problem, see if there is no virus file hidden in it, if any, timely delete these virus files, if not eradicate the words, Then you need to format the USB drive device to solve this problem. 2, u disk format problem If the USB

I encountered a problem when I recently completed the configuration. The previous idea was too naive. It may be a bit difficult to implement the pre-defined function. I have to write a filter driver, but I have never touched on the driver before, I don't have the confidence to figure it out in a short time, so it's just like other methods. Later I thought about it. I only had to change my mind, I thought of hiding the icon of the USB flash

Now use a USB flash drive to start the installation system is very common, and the boot file of the U disk is generally installed in the hidden partition of the U disk, you can prevent the virus intrusion. Let's take a look at this hidden partition of the U disk in detail now. In fact, the hidden partition of the U disk is also called UD file system, UD file system is relatively simple. Developers often de

When the USB flash drive is started and rhel5.8 is installed, the following error message is displayed: "your boot partition is on a disk using GPT partitioning scheme but this machine cannot boot using GPT", unable to continue the installation. Here, http://www.beckdim.cn/archives/209 Cause of error: the hard disk format was changed to GPT partition when vmware-vmvisor was installed on the machine. Solu

The flashback table, in effect, is to quickly restore the data in the table to a previous point in time or to the system change number SCN. To implement the flash back of the table, you need to use Undo information related to the Undo tablespace, which can be learned through the show PARAMETER Undo command. User modifi

First, add the environment variable devmgr_shownonpresent_devices to the system, the value is 1 Second, run the Device Manager and open the view hidden device. Expand the disk drive, storage Volume two, and the USB flash drive related to kill off. Third, open the Computer Management, the Removable Storage related to delete
