Controller and method of storage apparatus
View Patent ↗According to one embodiment, a controller for controlling a connected storage apparatus includes a storage unit and a control unit. The control unit acquires a password input by a user, judges whether or not the password is consistent with a password previously registered in the storage unit, cancels authentication data that is stored in the storage unit and enables reading and writing toward the storage apparatus of data and allows the formatting toward the storage apparatus in a condition that the password is consistent with the password previously registered in the storage unit, and disables reading and writing toward the storage apparatus of data and formatting toward the storage apparatus in a condition that the password is not consistent with the password previously registered in the storage unit.
1. A controller for controlling a connected storage apparatus, comprising:
a storage unit; and
a controller configured to
specify a type of the storage apparatus;
in response to a determination that the storage apparatus corresponds to the type specified by the controller unit:
carry out an authentication of the storage apparatus by using authentication data that is stored in the storage unit and that enables reading of data from and writing of data to the storage apparatus; and
prohibit reading of data from and writing of data to the storage apparatus and allow formatting of the storage apparatus in response to a determination that the authentication is not consistent;
in response to a determination that the storage apparatus does not correspond to the type specified by the controller unit:
acquire a first password as an input from a user,
judge whether or not the first password is consistent with a second password previously registered in the storage unit,
in response to a determination that the first password is consistent with the second password previously registered in the storage unit:
delete the authentication data, and
allow formatting toward the storage apparatus, and
in response to a determination that the first password is not consistent with the second password previously registered in the storage unit:
prohibit reading of data from, writing of data to, and formatting of the storage apparatus.
2. The controller according to claim 1 , wherein the controller is further configured to display a screen for inputting the first password on a display and acquire the password in response to the determination that the storage apparatus does not correspond to the type specified by the controller unit.
3. The controller according to claim 1 , wherein the controller is further configured to allow reading of data from and writing of data to the storage apparatus in response to the determination that the storage apparatus corresponds to the type specified by the controller unit and a determination that the authentication is consistent.
4. The controller according to claim 1 , wherein the storage apparatus is a storage apparatus of an image forming apparatus.
5. A method for controlling a storage apparatus connected with an apparatus that comprises a processor and a storage unit, comprising:
in response to determining that the storage apparatus corresponds to a predefined type of storage apparatus:
performing an authentication of the storage apparatus by using authentication data that is stored in the storage unit and that enables reading of data from and writing of data to the storage apparatus; and
prohibiting reading of data from and writing of data to the storage apparatus and allowing the formatting in response to a determination that the authentication is not consistent;
in response to determining that the storage apparatus does not correspond to the predefined type specified by the controller unit:
acquiring a first password as an input from a user;
judging whether or not the first password is consistent with a second password previously registered in the storage unit;
in response to determining that the first password is consistent with the second password previously registered in the storage unit:
deleting the authentication data, and
allowing formatting of the storage apparatus; and
in response to determining that the first password is not consistent with the second password previously registered in the storage unit:
prohibiting reading of data from, writing of data to, and formatting of the storage apparatus.
6. The method according to claim 5 , further comprising
in response to determining that the storage apparatus does not correspond to the predefined type, displaying a screen for inputting the first password on a display and acquiring the password.
7. The method according to claim 5 , further comprising allowing reading of data from and writing of data to the storage apparatus in response to the determination that the storage apparatus corresponds to the type specified by the controller unit and a determination that the authentication is consistent.
8. The method according to claim 5 , wherein the storage apparatus is a storage apparatus of an image forming apparatus.
