  • [アーティクル]

[Removable Storage Manager is no longer available as of Windows 7 and Windows Server 2008 R2.]

The following are the Removable Storage Manager functions.

Change Detection Functions

RSM does not detect inject and eject operations on standalone drives unless requested to do so by the application. Although some RSM functions automatically begin change detection of certain devices, applications that require current information on the presence or absence of media in standalone drives must use these functions to request RSM to detect the changes. With change detection enabled, an application can use database notification functions to be notified when media is injected and ejected. You can use the following functions:

Cleaner Management Functions

RSM can automatically clean tape drives that become dirty through use. Use the following functions to control drive cleaning:

Note

The Removable Storage Manager functions were defined when the technology was previously named NTMS. As a result, many function names contain the prefix "Ntms". Similarly, the "scratch" pool was renamed "free", and the "foreign" pool was renamed "unrecognized". The term "partition" was replaced with the term "side".
