Can you disable the mobile hard drive to play automatically by modifying the registry?

This is not a mobile hard disk problem, is windows in the detection of CD-ROM, mobile hard disk insertion, such as AutoPlay, you can close the registry.

Open Registry Editor, expand to the Hkey_current_user/software/microsoft\windows\currentversion\policies\exploer primary key, and in the right pane find the NoDriveTypeAutoRun ", that is, this key determines whether to perform CDROM or hard disk autorun functions.

Double-click "NoDriveTypeAutoRun", by default (that is, you have not banned Autorun function), you can see in the pop-up window "NoDriveTypeAutoRun" Default key value is 95,00,00,00. The first value, "95", is a 16-in value, which is the same as all of the devices that are prohibited from running automatically. Converting "95" to binary is 1001 01 01, where each

A bit represents a device, and different devices in Windows are represented by the following values:

Device name the number of device names means the device name meaning with the following values

Dkive_unknown 0101h Unrecognized device type

Drive_no_root_dir 1002h Drive without root (DRIVE without root directory)

drive_removable2104h removable drive (removable DRIVE)

drive_fixed3008h Fixed Drive (DRIVE)

Drive_remote 4110h Network Drive (Network DRIVE)

drive_cdrom5020h Optical Drive (CD-ROM)

Drive_ramdisk 6040h RAM diskette (RAM disk) retains 7180h unspecified drive type (not yet specified DRIVE disk)

The value "0" in the table listed above indicates that the device is running, and a value of "1" indicates that the device is not running (Windows prohibits 80h, 10h, 4h, 01h, by default, these devices run automatically, and these values add up to just 16 95h, so NoDriveTypeAutoRun "The default key value is 95,00,00,0 0."

It is easy to see from the above analysis that, by default, the devices that will automatically run are Drive_no_root_dir, drive_fixed, Drive_cdrom:, drive_ramdisk these 4 reserved devices, so you want to prevent the hard drive from automatically running Autorun. INF file, you must set the value of drive_fixed to 1 because the drive_fixed represents a fixed drive, that is, the hard drive. Thus, the original 1 00101 01 (In the Table "value" column from the bottom up) will become binary 10011101, to 16 into 9 d. Now, to change the key value of "No Drive Type AutoRun" to 9d,00,00,00, turn off Registry Editor and restart the computer to turn off the AutoRun function of the hard drive.

How do I disable the CD autorun function? In fact, the Drive_cdrom is set to 1 so that the first value in the "No Drive typeautorun" key value becomes 10110101, or 16 B5. When the first value is changed to B5, the Registry Editor is closed and the CDROM autorun function is turned off after restarting the computer. If only want to prohibit "BU software cd AutoRun function, but also retains the CD audio disk automatic playback ability, at this time simply" No Drive Type AutoRun "key value to: bd,00,00,00 can. If you want to restore the Autorun function of the hard drive or the optical drive, reverse: the direction of operation.
