Bad Block/Sector
An area on the media that is damaged and thus not reliable (detected by ECC). Such areas are generally auto assigned to spare sectors
Binary
Means of storing data on media, using two digits, (i.e. 0 & 1)
Bit
Binary Digit (i.e. 0 or 1). The form in which computers process information
Block (also cluster)
A group of sectors accessed/stored as a logical unit
BIOS
(Basic Input/Output system, firmware that is permanently stored in the memory of the CPU). The BIOS ROM first performs test routines when a system is switched on. It searches for and loads the operating system from the disk and contains programs to access the system hardware
BPI

Buffer
A part of the HDD which temporary stores data. The buffer compensates for a difference in data transfer rates and data processing rates
Byte
a number of bits, considered a unit (8 bits = 1 byte)

Scanning
The most common practice of encoding real images into digital form Accomplished by use of a scanner which passes an image sensor across the original
Screen grabs
Common term for the capturing screen rasterization images and video stills to digital files. Can be preformed with software or hardware, but quality may vary between method used.
SCSI
Small Computer System Interface. The abbreviation is pronounced “scuzzy.” A connection that allows high-speed information transfer between the computer and any external devices at speeds in the range of 4 to 5 megabytes per second. This specification also allows multiple devices to be connected via addresses to a single port (receptacle).
SCSI-II
A specification developed to provide greater speed and performance. An SCSI-II connection provides transfer rates ranging from 10 to 40 megabytes per second.
Selection
The term for indicating the desired area to be effected by editing.
Sharpen
To increase contrast along object edges to improve image appearance.
SIMM
Single In-line Memory Module. A small narrow circuit board containing Random Access Memory Chips (the electronic devices that store data while your computer works with it). SIMMs plug into special slots inside the computer to give the computer extra memory.
Special effects
Digital image manipulation techniques for enhancing quality or creating unusual appearances. Can also be used to remove undesirable image attributes.
Spray
To paint with a diffused edge to simulate “air-brush” feathering
Storyboard
A method of planning the content of a presentation by drawing sketches of each screen with notes about what happens in that scene.
Substitution
the process of replacing colors in a image with colors or patterns on the pallet for the image. this is implemented during color format conversion and pallet correction
SyQuest
A manufacturer of SCSI removable cartridge hard drives. This drive specification has been widely used in pre-press and publishing situations.
I can create a collection of pictures giving a 360-degree view from a certain spot, just taking a bunch of photographs from the same spot but in a different direction. However, what software could I use (on Windows) to stitch these images together to get one big image? I prefer something that would stitch them…
Case:The HIS system of Wenzhou People’s Hospital uses two Dell R900 servers to share a dual -machine thermal preparation made of ROSE HA for MD3000 storage. The database file is stored on this MD3000 storage.On the 2nd of the 2nd on the 2nd, the hospital client could not log in to the HIS system. The…
If a drive has damaged data in the SA, for example in the firmware code module, it might become unusable. To repair these disks, the HDD can be switched to a so called ‘safe mode’, by setting specific jumpers on the drive. If the drive is operating in safe mode, it bypasses its own firmware. Instead, it wants the user to upload firmware to its ram. If the user uploads a correct ‘temporary’ firmware to RAM, it starts executing that firmware. If this uploaded RAM code (the ‘loader’) starts operating, the user can then start to issue ATA commands to the drive to modify the damaged modules.
Firmware files that you can find on a site like this contain a lot of files. First, there is the ‘loader’ file (*.LDR). This file is the ‘temporary’ firmware code, that’s being uploaded to the RAM (so, it’s not being written to disk). Then, there are a lot of ‘*.RPM’ files. These files represent the different modules, which can be written to the SA. The filenames consist of 8 numbers. The first 4 numbers specify the (hex) UBA and the second 4 numbers represent the hexadecimal module size in sectors (each sector normally contains 512 bytes, so for example, if a filename ends in 0002, then that module is 1024 bytes long). So, in short, after uploading the loader to RAM, the user can start replacing damaged modules by overwriting them with correct ones.
BTW, please note that the term ‘firmware’ for the packages on this site is not very well chosen, since these packages contain all needed modules to repair a HDD and not just the firmware (=code) module.
Anyway, if you’re looking for a specific firmware module, you can do 3 things:
1) rip the firmware modules from the SA of an identical HDD
2) get these modules from a friend (or for example, from the files section on this site: www.firmwarebase.com)
3) use a firmware update program from the vendor.
About this last option: firmware updates from vendors are pretty rare, since firmware code almost never needs to be replaced. However, Maxtor for example, had some problems with the firmware code on some Diamondmax HDD models. So, they issued a firmware update. This update consists of 2 files:
1) the executable file that issues the ATA ‘download microcode’ command to upload the firmware files to the HDD
2) The firmware code, consisting of the ‘main’ firmware code and ‘overlay’ code modules.
Case:Customers call says that their company currently has a set of HP RAID 5 array CRASH must be recovered. This array is listed as a database shared by the company’s hundreds of people.The storage volume is about 5.2TB. Customers first contact the data recovery company to inform the preparation of the data recovery company. Solution:After…
We first look at the following two pictures. Picture 1 is the “BIOS CHIP” of the circuit board. When we replace the PCB, we need to swap the “BIOS CHIP” with your original PCB. Picture 2 shows the “Board Number” of the board, and the “Board Number” must be the same! FAQs of 100815597 PCB…
