A computer readable storage medium having computer readable code embodied on the computer readable storage medium, the computer readable code comprising:

• (a) first code, for a driver of a data storage device, for querying a preceding access to said data storage device;
• and
• (b) second code, for said driver, for:
• if said querying indicates a failure of said preceding access, repeating said preceding access until said querying indicates a success of said preceding access;
• said first and second code being callable by an application program in a single call to said driver.

A computer readable storage medium having computer readable code embodied on the computer readable storage medium, the computer readable code comprising:

• (a) first code, for a driver of a data storage device, for querying a preceding access to said data storage device;
• and
• (b) second code, for said driver, for initiating a new access to said data storage device if said querying indicates a success of said preceding access;
• said first and second code being callable by an application program in a single call to said driver.

• (a) providing an access command in an API of a driver of the data storage device;
• (b) providing a verification command in said API of said driver;
• (c) issuing said access command to initiate an access of the data storage device by said driver;
• and
• (d) subsequent to said issuing of said access command, issuing said verification command to verify a success of said access.
