Abstract: Computer-based methods, techniques, and systems for automatically protecting a storage device from unwanted alterations are provided. Example embodiments provide a Disk Access Redirection System, which includes a Redirection Driver, an Available Space Table (“AST”), a Protected Space Redirection Table (“PSRT”), and optionally an Unprotected Space Table (“UST”). The Redirection Driver is installed and registered with the computer operating system so that it can intercept storage device access requests (such as a disk read/write). When a storage access request for a read or write is sent, the request is intercepted by the Redirection Driver, transparent to the code that invokes the storage access request.

When a storage access request for a read or a write is sent, the request is intercepted by the Redirection Driver, transparent to the code that invokes the storage access request. Upon intercepting a write request, the Redirection Driver determines whether the target location is protected (using the PSRT and UST). If so, the Redirection Driver writes to a redirected data area, allocating more space to the redirected data area as needed.
