Attributes (continued) ID 192 193 194 195 196 ATTRIBUTE NAME Power-off Retract Count Load/Unload Cycle Temperature Hardware ECC Recovered Reallocation Event Count Current Pending Sector Count BETTER DESCRIPTION Low Low Low High Low This is how many times the heads are loaded off the media. This is the number of load and unload cycles into head landing zone position. This is the hard drive's internal temperature. This is the time between ECC (Error Correction Code)-corrected errors. This is the total number of reallocation (remap) operations. The raw value is the total attempts to move data from reallocated sectors to a spare area. Successful and unsuccessful attempts are both included. This is the number of unstable sectors awaiting reallocation. If the sector is later successfully written or read, this value decreases and reallocation is not performed. Only failed write attempts cause a reallocation, not read errors. This can be difficult to test since only direct I/O writes to the disk cause reallocations, not cached writes. This is the number of errors reading or writing a sector that were not correctable. An increase in this value is an indicator of disk surface defects or mechanical subsystem problems. This is the number of data transfer errors through the interface cable according to the ICRC (Interface Cyclic Redundancy Check). This is the total number of errors in writing sectors. 197 Low 198 Uncorrectable Sector Count UltraDMA CRC Error Count Write Error Rate / Multi-Zone Error Rate Soft Read Error Rate Data Address Mark Errors Run Out Cancel Soft ECC Correction Thermal Asperity Rate (TAR) Flying Height Spin High Current Spin Buzz Low 199 200 Low Low 201 202 203 204 205 Low Low Low Low Low This is the number of read/write head off-track errors. If the value is not zero, make a backup. This is the number of data address mark errors. This could also be a different, manufacturer-specific attribute. This is the number of ECC (Error Correction Code) errors. This is the number of errors corrected by software ECC (Error Correction Code). This is the number of thermal asperity errors.
