This grinding can also happen if accidentally having a shortcut pointing to a file placed on A: or B: drive.I decided to write this article for everyone who wants to get advice on how to create an autorun USB flash drive. Note if having Autorun.inf checking enabled for floppy drives, then it might at random access the floppy drive and grind for a long time searching for the Autorun.inf. Note if one don’t want to enable autorun for a single CD-ROM, then instead just hold down the SHIFT key while inserting the CD-ROM. Media like Audio CDs will not be affected by the setting of these policies. Note these policies only work on media which are able to contain an Autorun.inf file. In the case of DRIVE_REMOVABLE, the action key is required. It is only supported for drives of type DRIVE_REMOVABLE and DRIVE_FIXED. The action key is only used in Microsoft Windows XP Service Pack 2 (SP2) or later. If you need to make a USB storage device perform Autorun, the device must not be marked as a removable media device. The Autorun capabilities are restricted to CD-ROM drives and fixed disk drives. Note there is a little confusion about autorun on USB drives, which have caused the creation of software like APO Usb Autorun:Īutorun.inf files are not supported under Microsoft Windows XP for drives that return DRIVE_REMOVABLE from GetDriveType.

Bitĭisables the checking for Autorun.inf on A: + C: One can configure what drive-letters shouldn’t be checked for Autorun.inf. If the media has changed then it checks if a file named Autorun.inf is placed in the root. Windows is by default configured to poll all devices every second to check if the media has changed since last poll.
