SAMSUNG HARD DISK DRIVE << Major components of HDD >> HDD is formed by major components as follows: Base, Cover, ARM(E-Block), Latch, Crash Stop, Pivot Bearing, Breather Filter, Window Clock, Window Push Pin, Jump Pin, Spindle Motor, Actuator, Magnetic Head, Magnetic Disk, PCBA 1 Base Base could be a basic frames for HDD assembly. Spindle motor, ARM, VCM, cover and PCBA are assembled on it, and other components are sub-assembled on those configuration.
SAMSUNG HARD DISK DRIVE 6 Pivot Bearing Pivot bearing is a roll bearing fixed the center of gyration of ARM. Inner Race is fixed by screw after being connected to Base pivot and outer Race is fixed by retaining ring after being connected by ARM's hole and make the ARM's revolving movement actively. 7 Breather Filter In the interior of HDD, air flow is formed by the spinning disk in high speed and pressure distribution occurred.
SAMSUNG HARD DISK DRIVE put power on and no matter what HDD read or write data,spindle motor always revolve. Besides accurate reading from the media point of view is possible when maintain the constant speed within 0.1%,rotation error. The control circuit of spindle motor receive the index data from the spindle motor or media at every spin and check whether constant speed persists or not then revise the speed. Spindle motor is applied to DC brushless motor.

SAMSUNG HARD DISK DRIVE 9. Caution ※ Hard disks are very fragile electro-mechanical devices, which are very sensitive to external shock and vibration, therefore be careful when you use not to be impacted and broken by static electricity. 1) Handling Damage example from impact ① If you move HDD while it is running: Spindle motor of the interior in HDD start to spinning at high speed as soon as power on.
SAMSUNG HARD DISK DRIVE Attachment 1. The basic information related HDD ※ 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. The tracks are divided into spaces regularly. The number of tracks is different according to the size and capacity of disk.
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. If boot record is vanished, the disk is useless entirely. The physical information mean, for example, the number of FAT, capacity of disk something like that.
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. The size of partition from dos 4.0 isn't restricted, hard disk over 32MB(to DOS 3.3) must be treated as a independent drive each diving two more partitions. ⑦ Transfer Rate: The mass of controller is transferred a data from hard disk.
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. ●Buffer: The RAM where executed data between HDD and host computer is stored in RAM temporary.
SAMSUNG HARD DISK DRIVE Attachment 2. Explanation of HDD terms Access Read, write, or update inforamtion on some storage medium such as a disk. Access time The interval between the time a request for data is made by the system and the time the data is available from the drive.Access time includes the actual seek time, rotational latency and command processing overhead time.
SAMSUNG HARD DISK DRIVE BEARING Abbreviation of pivot bearing, Mediator of Arm and Base which is located in the center of ARM 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. BIOS Basic Input/Output system: Control program/sub-program can control computer and around device.
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. Tracks are divided to k/Sector sector and it organized ID information and data and ECC. ID information is a sort of address information to seek data sector requested from host computer.
SAMSUNG HARD DISK DRIVE Enhanced IDE The existing IDE specification enable to adhere only 2 drives and transferring speed was low. But HDD efficiency are resulted to low the whole capacity according to getting system efficiency higher. Enhanced IDE has specification of revised IDE-AT interface by current BIOS and 528Mb barrier and we settled the low speed problem with this new spec. Same as Fast-IDE Interface or Local Bus IDE-AT Interface. EOL End of Life. EPROM Erasable programmable read only memory.
SAMSUNG HARD DISK DRIVE HDD 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) Head Crash The damages of read/write and media cause a sudden contact between head and disk surface, they are also occurred because of dust,particles or other contamination within HDA. Head Stack Status ARM and HGA assembled.
SAMSUNG HARD DISK DRIVE LBA mode Logical block allocation. DOS mode to resolve 528MB capacity restriction. LED 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. Low-level formatting Operating system make sector on disk enable to access in proper region in order to create file structure. Master HDD become booting when put Jumper control & CMOS setup) 2 more IDE drives.
SAMSUNG HARD DISK DRIVE Overhead Time to perform the real order for controller, host adaptor and drive. the faster performing time. The faster overhead is, Overwrite Recorded data erased by overlapping the existing data. Parking Zone = Landing Zone Partition When we use one HDD for multi ones dividing section logically, every memory section is partition, For example, 2.5GB HDD can be used for one 2.1GB computer and one 400MB. PCBA Printed Circuit Board Assembly.
SAMSUNG HARD DISK DRIVE RETAINER RING Component could fix bearing when inserted to ARM. RLL Encoding method "run length limited data" to magnetic pulse. It can store data 50% more than MFM(Modified Frequency Modulation) method. RMA Return Material Authorization ROM Searching only memory. memory would not erase during off, so we use this to program or data need not change in PC. Mask ROM input contents when it's manufactured and PROM recorded program by user.
SAMSUNG HARD DISK DRIVE Transfer rate Data transferring speed among PC and other devices of HDD. Tri-pad head 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. Unformatted capacity HDD capacity before formatting. USB Universal Serial Bus.
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. The main occurring cause of physical bad sector are particle,impact,vibration.
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. If internal stack overflow error occurred on the basis of MS-DOS system (MS-DOS, MS-WINDOWS95), increase the number of internal stacks of CONFIG.SYS file and the usages are as follows.
