Exploded View SpinPoint M40 Series... - Page 7 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.
- Page 8 SAMSUNG HARD DISK DRIVE 5 Crash Stop Crash stop is made of elastic material and weaken a impact of actuator in emergency condition, head getting out of data zone when it move to parking zone or seek. 6 Pivot Bearing Pivot bearing is a roll bearing fixed the center of gyration of ARM.
- Page 9 SAMSUNG HARD DISK DRIVE element (these are sensitive to voltage change). The magnetic disk of hard disk is running by DC Brushless direct drive motor directly. Brush has long life and high reliability because it doesn't have belt. Recently we use flat motor to be adopted to the request of minimizing.
- Page 10 SAMSUNG HARD DISK DRIVE 16. Ramp 2.5 inch drives usually adopt Load /Unload ramp system to prevent head slap for disk basically. Head is putted safely on the ramp which is located off disk-outer diameter at non-operating It makes head avoid to slap disk during the external shock. and play a major role to move to disk smoothly at loading and move smoothly and safely to itself to park head at power-off.

- Page 24 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 25 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 26 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 27 SAMSUNG HARD DISK DRIVE ⑬ ECC On-the-Fly: A region isn't able to read exist in media. When we find defect like this in manufacturing process, we replace with the normal region. Thus we can supply perfect drive to user. Defect magnet is a method can arrange the defects in read/write from the replaced sector.

- Page 29 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 30 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 31 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 32 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 33 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 34 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 35 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.

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 38 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.
