Abstract

Provided are a method, system, and article of manufacture for providing removable storage management services using removable storage error information. Read/write error information is obtained for at least one removable storage by interfacing with the removable storage manager. The obtained read/write error information for the at least one removable storage is processed to determine read/write error rates for the at least one removable storage. A determination is made as to whether the determined read/write error rates for the at least one removable storage exceed at least one read/write error threshold. At least one message is sent to the removable storage manager to replace the at least one removable storage having read/write error rates that exceed the at least one read/write error threshold.

8. The method of claim 1, further comprising:

billing a customer periodically for replacing the at least one removable storage having read/write error rates that exceed the at least one read/write error threshold.

9. A system in communication with a removable storage manager managing access to at least one removable storage, comprising:

a processor; and

a computer readable medium having a removable storage service provider executed by the processor to perform operations comprising;

interfacing with the removable storage manager to obtain read/write error information for the at least one removable storage;

processing the obtained read/write error information for the at least one removable storage to determine read/write error rates for the at least one removable storage;

determining whether the determined read/write error rates for the at least one removable storage exceed at least one read/write error threshold; and

sending at least one message to the removable storage manager to replace the at least one removable storage having read/write error rates that exceed the at least one read/write error threshold.
