Page 25: Attachment 1. The Basic Information
SAMSUNG HARD DISK DRIVE . The basic information related HDD Attachment 1 ※ The basic information of HDD 1) The logical elements constituted hard disk ① Track: The data inputted by computer was written at tracks on disk. The tracks, in spite of invisible,are the concentric circles from the center of disk to the outside. - Page 26 SAMSUNG HARD DISK DRIVE 2) The logical mechanism of hard disk Hard disk consists of boot record, FAT, root directory, data field. ① Boot Record: Boot record is consists of sector 1, track 0, side 0. Boot record is the one of most important parts. It has some information about the physical structure of disk.
- Page 27 SAMSUNG HARD DISK DRIVE ⓐ DOS PARTITION : This is to dos as system disk is to floppy disk and dos is run by this partition. ⓑ EXTENDED DOS PARTITION : The rest region of the disk was occupied by dos partition.
- Page 28 SAMSUNG HARD DISK DRIVE ⑮ Master/Slave/Cable Select: When we attached 2 IDE drive, one is master and the other is slave. Being a M/S whether or not of drive is determined by jump in drive or cable select. ● BPI: Abbreviation of bit per inch, recording density towards a circumference. Usually we decide the maximum diameter of track.
- Page 29 SAMSUNG HARD DISK DRIVE 2. Explanation of HDD terms Attachment Air Bearing Surface. Establish flat surface slantingly at the both sides of head to make head rise on disk by using air pressure. Access Read, write, or update information on some storage medium such as a disk.
- Page 30 SAMSUNG HARD DISK DRIVE Abbreviation of pivot bearing, Mediator of Arm and Base which is located in the center of ARM BEARING and it can rotate smoothly. Bezel A plastic panel that extends the face of a drive so that it covers a computer's drive bay opening.
- Page 31 SAMSUNG HARD DISK DRIVE Data is recorded on lots of circle in media in HDD, we call these circles track.. We record data at both sides of media and HDD has many media layers. so it has several tracks which have Cylinder/Trac the same radius, we call this concentric circle collection of track Cylinder.
- Page 32 Height more specified mechanical design. Form factor Industrial specification decided diameter of Disk. 3.5", 2.5" in case of Samsung. Recording the particular signal to divide track and sector and this information should be recorded Format on disk in first before user want to store data. Be careful because formatting erase all recorded information.
- Page 33 SAMSUNG HARD DISK DRIVE Hard Disk Drive, memory device by transferring data to permanent magnetic field rather than digital pulse. It organized HDA and PCBA. Head Read/write data on disk directly. (MIG, Thin film, MR,GMR) The damages of read/write and media cause a sudden contact between head and disk surface, Head Crash they are also occurred because of dust,particles or other contamination within HDA.
- Page 34 SAMSUNG HARD DISK DRIVE LBA mode Logical block allocation. DOS mode to resolve 528MB capacity restriction. Light Emitting Diode. Used for signal light to all kind of electric containing computer. Low profile One of standard height of HDD, the real height is 1 inch.
- Page 35 SAMSUNG HARD DISK DRIVE Time to perform the real order for controller, host adaptor and drive. The faster overhead is, Overhead the faster performing time. Overwrite Recorded data erased by overlapping the existing data. Parking = Landing Zone Zone When we use one HDD for multi ones dividing section logically, every memory section is Partition partition, For example, 2.5GB HDD can be used for one 2.1GB computer and one 400MB.
- Page 36 SAMSUNG HARD DISK DRIVE RETAINER Component could fix bearing when inserted to ARM. RING Encoding method "run length limited data" to magnetic pulse. It can store data 50% more than MFM(Modified Frequency Modulation) method. Return Material Authorization Searching only memory. memory would not erase during off, so we use this to program or data need not change in PC.
- Page 37 SAMSUNG HARD DISK DRIVE Transfer rate Data transferring speed among PC and other devices of HDD. The existing thin film head have 2 ABS and adding one more ABS, head is designed to be Tri-pad head profitable to low flying height. Produced by SAE, ReadRite company.
- Page 38 SAMSUNG HARD DISK DRIVE Attachment3. Q&A ※ Customer's Q&A 1) What is "Bad Sector"? Bad sector is divided physical Bad sector(Hard defect) and logical Bad sector(Soft defect). ① Physical Bad sector Visual defect occur in the surface of disk where is recorded data, it contain the minute defect could checking with electric microscope.
- Page 39 SAMSUNG HARD DISK DRIVE mode, and extend capacity by raising the number of cylinder. Currently most of hard disk is applied to LBA mode, so it set as LBA or AUTO in BIOS set-up. 4) PC is downed with the message of "Stack Over Flow" while HDD running or can't recognize HDD.
