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 BF41-00322A PCB…
Do two computers connected on the same Wi-Fi have the same IP address (for example, my dad’s computer and my computer, at home)? If so, how does the outside world distinguishes one computer with the other? (for example, when a server wants to send us back some data). Solution: You’re both seen as having the…
PC
Personal computer.
PRML (Partial Response Maximum Likelihood)
A read channel using sampled data, active equalization and Veterbi detection to accurately retrieve the user data off the disk.
Partition
A way to logically divide a hard drive so that an operating system treats each partition as a separate hard drive. Each partition has a unique drive letter.
Passive Termination
A termination architecture that is used to match the impedance at the end of the SCSI bus by using a voltage divider network of passive resistors.
Peripheral
A device that performs a function and is external to the system board. Peripherals include displays, disk drives, and printers.
Platform
A basic design from which a series of products is engineered and produced.
Platter
An actual metal (or other rigid material) disk that is mounted inside a fixed-disk drive. Many drives consist of multiple platters mounted on the spindle to provide more data storage surfaces. Each platter may use one or both surfaces to store data.
Port
A connection or socket on the motherboard or controller card. A motherboard may have one or two ports (primary and secondary). If your motherboard has only one port, you may need to add a controller card to create a secondary port.
Pre-fetch
Instructions that are loaded into a queue when the processor’s external bus is otherwise idle.
Primary Partition
The partition where the operating system files are stored. To start your operating system from a hard disk, it must have a primary partition. You must also make the primary partition active.
Product Road Map
A company’s plan for the introduction of new products.
Protocol
A convention of data transmission that defines timing, control format, and data representation.
Programmed I/O
In a disk drive with an AT interface, data transfers between the drive and host using programmed I/O (PIO). The host uses PIO to write to the Command Block Registers (CBRs) when transmitting control information, such as the location of a read command.
Proximity Recording
A recording technology that increases recording density by allowing the read/write head to come in close proximity to the disk surface.
Case:The customer first inquired and said that a good friend borrowed an Apple mobile hard disk to store data.When Ms. Liu used the mobile hard disk returned by her friend, she was surprised to find that the data stored in the mobile hard disk was all gone. She immediately asked her friends that the situation…
For some reason all of a sudden when I update cells in Excel, my equations are not being updated. For example, I have a simple equation =SUM(C4:C16). If I change any of the cells in C4-C16, the answer doesn’t get updated… I don’t know what happened I’ve never seen this fail before. Any ideas? Solution:…
PC3000 PCI version, this Pirated product will not perform or functions:
1). Product will run a while with limited functionality and after a while it will stop working due to DATE/TIME, hard disk with bad sectors, any changes to the G-LIST will make the card unusable.
2). Certain functions will not work properly, often hang or crashes, Hard disk that comes with PC3000 PCI cloned must be Maxtor 4D040H2 or 6Y080L types, imagine these drives have full potential of breaking down, they purposely use these type of HDD so they can sell more pirated PC3000 PCI cloned.
3). Windows operating system in Chinese language so guess what…it will drive you crazy.
4). Hard Disk must be cloned again once the PC3000 PCI is locked due to piracy prevention is detected (e.g. Asking for renew license key), cloning procedure is totally time wasting.
5). If something goes wrong, Chinese seller will deny and ask you to get F##CK!
6). PC3000 PCI is updated regularly meaning that once you bought the pirated ones you can’t update the software. The Chinese will ask you to buy a new one instead. (That’s the trick…they will keep asking to buy a new updated PCI claiming it is better than the previous version, e.g. PC3000 PCI version 1.1, 2.2, 2.XX and so on), after a while they will tell you a new system is added so you don’t have to clone if something goes wrong, guess what? they will ask you to buy a new one again because your old one can’t be updated.
7). Average pirated copy of PC3000 PCI selling for around US$400 – US$600, every few months there is a new version comes out, so you keep spending $600, over the course of 1 year you can buy the new original PC3000 PCI with free updates for 1 year.
8). New original PC3000 PCI can run on any motherboard, Windows Operating systems English or other language, any types of CPU, HDD etc.
Hope this article helps people in deciding whether or not it’s worth buying the clones PC3000.

I want to append new data in a file stored in SSD. dd if=/dev/shm/test of=/data/sdb/test bs=1G oflag=append But df -h shows the dd command always overwrite the test file, instead appends new data in the test file. I also tried dd if=/dev/shm/test of=/data/sdb/test bs=1G conv=notrunc It does not work, either. Solution: What about: dd if=/dev/shm/test…
