Solution for unsecure deletion of mobile hard disks under win7

First, you must understand that the purpose of safely deleting hardware is to reset the hard disk head and stop reading and writing to protect the hard disk.

In XP, after the hard disk is safely deleted, the mobile hard disk will be stopped after power failure.

After Vista and win7 safely delete the hardware, they will not cut off the power connection, but will only disconnect the data. That is to say, the hard disk is still rotating, but it can be directly pulled.

What if the hardware cannot be safely deleted? (It indicates that some basic methods have been used, but they are still not masturbate ))

I will tell you the solution here. I will not talk about such methods as logout, standby, and shutdown, because most people will not do this.

(1) Use unlocker, a free right-click extension tool.

After installation, right-click the drive letter of the USB flash drive, select unlocker to unlock it, and delete it safely.

This is a non-basic approach. If not, skip to step 2.

When I used unlocker 1.9.0 to unlock the Mobile Disk, I found that the assumer.exe process was accessing the disk. So I unlocked all the disks. It is reasonable to say that the mobile hard disk can be safely deleted at this time, the system still prompts that the hard disk is in use and cannot be safely deleted.

(2) The other cause of unsecure deletion is that some software processes prevent the removal of mobile hard disks, such as some anti-virus software, win7 processes and QQ.

The specific solution is: Right-click "my computer" ---> "management" ---> "Event Viewer" ---> "Windows Log" ---> "system ", search for logs with yellow warnings.

I found:Applications with process ID 2468Program\ Device \ harddiskvolume1 \ windows \ system32 \ svchost.exe removes or pops up USB \ vid_1058 & pid_071a \ 575850314533304658433836 from the device.

There are more than 10 svchost.exe in the win7process. Our job is to find the svchost.exethat corresponds to the process ID 2468. then we can safely delete the hardware.

Of course, some people also see the following information:The application with process ID 1128 \ device \ harddiskvolume4 \ ProgramFiles \ Tencent \ QQ \ bin \ qq.exe stops the removal or pop-up of the USB \ vid_1058 & pid_071a \ 575850314533304658433836 device.

That is to say, this is caused by QQ. After exiting QQ, wait a few seconds and click "delete" to delete the mobile hard disk, which should also be safely deleted.
