Thus, if a desktop disk without TLER starts delaying a response to a sector read, FreeBSD will retry the read with successively longer timeouts to prevent prematurely dropping the disk out Self-test supported. To look at timeouts we use command smartctl -l scterc /dev/sda. https://en.wikipedia.org/wiki/Error_recovery_control
The output looks so: # smartctl -l scterc /dev/sda SCT Error Recovery Control: Read: 70 (7.0 seconds) Write: 70 (7.0 seconds) # smartctl -l scterc /dev/sde SCT Error Recovery Control: Read: Software RAID Linux mdadm simply holds and lets the drive complete its recovery - however, the default command timeout for the SCSI Disk layer (/sys/block/sd?/device/timeout) is 30 seconds, after which it According adjustment of the system work parameters with the hard drive can be the reason why hardware exchange is not necessary.

For Mac OS X, as far as I know, there is a smartmontools port so the specified commands (from a rue) are quite feasible there. If you wish to use a custom timeout value, you can use the WDTLER.EXE utility directly with the -r# -w# parameters to specify how many seconds the Time Limit value should For example, 3ware 9650SE uses 20 seconds as the timeout, while for the LSI Logic used in IBM x-series it is 10 seconds.
