Table 17 equates the read and write retry count with the maximum possible recovery time for read and write

recovery of individual LBAs. The times given do not include time taken to perform reallocations. Reallocations

are performed when the ARRE bit (for reads) or AWRE bit (for writes) is one, the RC bit is zero, and the recov-

ery time limit for the command has not yet been met. Time needed to perform reallocation is not counted

against the recovery time limit.

When the RC bit is one, reallocations are disabled even if the ARRE or AWRE bits are one. The drive will still

perform data recovery actions within the limits defined by the Read Retry Count, Write Retry Count, and

Recovery Time Limit parameters. However, the drive does not report any unrecovered errors
