Patent ID: 8780471

Claim:
A system for linking errors to a particular tape or a particular tape drive, the system comprising: a processor to execute stored instructions; and a memory device to store instructions, the memory device comprising processor-executable code, that when executed by the processor, is to: obtain tape and tape drive combinations within the system; detect a read error or a write error that occurs with each tape and tape drive combination; analyze the read error or the write error by determining a write margin result by applying a logarithmic calculation to the age of data at a particular data point and an amount of data written at each data point, wherein the data includes read errors and write errors, and wherein the data point represents data collected for a particular tape and tape drive combination; link the read error or the write error to a particular tape or a particular tape drive based on the write margin result; designate the particular tape or the particular tape drive linked to the read error or the write error as bad; and render a notification of the particular tape or the particular tape drive designated as bad.
