7. How to use HUTIL Program
Write Head: All heads are progressed to write at the last cylinder (ID region). If it is fail to write due to cylinder error, progress again in the next inner cylinder. Record failure status to the corresponding head after progress error check to all 10 cylinders.( e.g.: Head 0 Fail, Head 1 Pass. ) remark "failure" if error occurred in Read Head: Seek 100 cylinders per OD, MD, ID regions
3 times per region. ( Judge failure by reading not the whole cylinder but servo sector only because it is apt to mistake failure to head failure due to scratch) PES Check (PES, RCO, Mechanism) : Compare PES value from the first cylinder starting OD(except MC ),MD,ID region to the 3rd

cylinder. (Check 30 times per 1 cylinder) 3 times per 1 cylinder.
Remark "failure" when error occurred more than
Maintenance Cylinder Check(M/C): Read Maintenance cylinder from the number of 0 to the last. In case of "MC", remark "failure" when error happened in one time. Media Check : Read from OD to ID region same as the existing read test function and progress "D/F" whenever defect occurred. Auto Defect Free: Reading along OD to ID region, progress "D/F" promptly if defect occurred. Read the next sector if no defect occurred and progress D/F if defect occurred. When we don't have any more cylinder space for D/F, stop progressing D/F and then remark defect status for the next 30 defects occurred from the D/F stopping location. Remark failure: - If the number of defects are same in OD,MD,ID region remark failure in order of OD > MD > ID. - If the number of defects are different in OD,MD,ID region remark failure in region have the most defects among OD,MD,ID region continuousness: Continuous scratch more than 15 cylinders divergence: Divergent scratch less than 15 cylinders Test OK: Remark "Test OK" if no problem occurred when test done. If it passed due to D/F, remark "Defect free by pass~" and show the corresponding failure region in the below. At this time, input the code of failure region shown and the control code 'is a "Defect controlled". Display Read time with checking during Read test, (Stop reading if expecting read time exceeded +10 when 50 % tested.)

Revised interface in IDE way, new specification to improve the existing method has problem of low speed. Embedded Servo: Arrange servo signal(timing,location control signal) to data and data track in parallel. Dedicated Servo: Mechanism of dedicated surface of disk have timing and positioning information only. Encoding is a data transferring method before recording data pattern to disk and Decoding is on the contrary. To read recorded data more easily and accurately, Encoding and Decoding should be needed. Coding methods are MFM.(2.7)RLL.(1.7)RLL.

Order of sector arranged within track. For example, interleave factor is 3:1 then arranged by 3 sectors for sector interval, that is, it is possible to read sector2 after reading sector1 by leaping over 2sector. We need 3 rotations to read all data of track. Now days, Most interleave is 1:1. Incoming quality control. Inspection process for import.
Device in type of hardware, it decide HDD connecting status (Master/Slave etc.) A small parts enable to choose drive running mode.(Master/Slave) KB = Kilo Byte, MB = Mega Byte, GB = Giga Byte. K,M,G have double meanings. First, K=1000, M=1000000, G=1000000000, second K=2^10=1024, M=2^20=1048576, G=2^30=1073741824. The second one is more accurate mean on HDD capacity, but we usually we use by the first one.

KB/MB/GB

Both of them means the landing location of head when spindle motor stopping. This zone used Landing for protecting the risk of data damage caused from the contact between head and disk, this Zone/Parking zone is not stored. Recently most drives using VCM are designed head should be landed in Zone landing Zone automatically. Latch LATCH SCREW Parts enable to hold ARM putting on head in constant power. HEAD is located in parking zone on off, at this time latch screw connected in parking magnetic and make head fixing. (latch force is determined by magnetic power )

Waiting time until target sector seek time after Read/Write Head arriving at the target track. Latency/Rota (Generally, 1/2 of spindle cycle ). One cycle time of disk is 16.7ms in case of spin speed is tional 3600rpm, then average waiting time should be 8.3ms. This Latency is a one of most factor for latency drive efficiency, transferring speed is better getting shorter waiting time.

To protect a sudden data damage, connect HDD in parallel and diverge data , that is high speed back-up device enable to improve data preservation and low speed access for tape the problem of the current back-up device. Random access Memory. Semiconductor memory enable to input and search,we have DRAM and SRAM. Look-ahead method is not only reading data requested from host but also reading- ahead continuous data to buffer sequentially, We improve data transferring speed because we don't need to read again in time host request information pre-read by applying for file's sequential saving method. Order of reading all data from HDD, read sector occur interrupt per every sector transferring, read multiple occur interrupt per designated sector number by set multiple order. Also read DMA occur interrupt only one time after transferring data from host request. For example, 4 is chosen by set multiple and host need 10 sectors then the below picture draw how to occur Interrupt.

Value Added Re-seller. Vendor sell the existing product after making higher value added. Voice Coil Motor: Stable and high speed motor applying speaker system, make move head in proportion to magnetic strength. Motor used voice coil has fewer components than step motor so it is strong for stress and abrasion and move head in high speed. They divided Rectangular and Flat coil type of VCM according to shape and Linear and Rotary type according to rotation method. Recently flat coil type and rotation type is general. Trapezoid shaping parts connected to ARM with winding coated write in 250 times. Disk drive same as fixed Disk and hard Disk. Winchester was the of developing model at that time by IBM, establish fixed magnetic disk within airtight space then head rise on connecting disk, we apply to all kind of hard disk drive now days. Make hole so head for servo write to write locational information could enter inside of HDD. Pin hole to enter HDA. Write cache improve system capacity, i.e. make possible to work while recording information on disk and this is risk to loose data when off but PC use write cache within operating system like smart drive to prevent that risk. The existing thin film head have 2 ABS and adding one more ABS, head is designed to be profitable to low flying height. Produced by SAE, ReadRite company.
