[Solved] Seagate ST3000DM001-9YN166: Load Cycle Count

This is the list of known S.M.A.R.T. attributes supported by IDE and Serial ATA hard disks.
Note: some manufacturers may use the attributes for different purposes also.
Attributes not listed here are "vendor specific" attributes (their purpose is not known)

Raw Read Error Rate - Errors occured while reading raw data from a disk
Indicate problem with the disk surface or the read/write heads.
Critical attribute

Indicate problem with the disk surface or the read/write heads.
Critical attribute

Command Timeout - Indicates a number of aborted operations due to hard disk timeout
Critical attribute

Read Channel Margin - Margin of a channel while reading data
The exact function of this attribute is not specified.
