查询词典 target disk

The main related design are on the following: Using RS232 to realize the target of communication links between host computer and target machines, and to test the PC serial; to make target machine startup disk; to design the Interface of target Machine ; to develop a device driver program module against remote data acquisition and control system ADAM5000 using the technical framework of xPC; and to realize Data Acquisition and controlling according to using ADAM5000 device driver program module against an actual water level in the block diagram of PID processing control system, the generation of real-time control procedures at the scene Debugging was expected to controlling effect.

本课题主要做了以下相关设计：利用RS232实现宿主机与目标机之间通信连接及对PC机串口的检测、制作目标机启动盘、设计目标机界面及在xPC技术框架下针对远端数据采集与控制系统ADAM5000开发了设备驱动程序模块，并以一个实际水箱液位为背景，在已有的PID液位过程控制系统算法框图中应用该设备驱动程序模块实现对现场设备的数据采集和控制，所生成的实时控制程序在现场调试中获得了预期的控制效果。

One magnetic suction cup, is the production of ordinary electromagnetic sucker, permanent magnet disk, circular disk, the disk and professional powerful multifunction disk a total of five series of more than 150 varieties of specifications, in addition to permanent magnet lifting device, frame-type high-performance back demagnetizer , rectifier controllers and other products.

其一磁力吸盘，现生产普通电磁吸盘、永磁磁盘、圆形磁盘、多功能强力磁盘和专业用磁盘共五大系列150多个规格品种，此外还有永磁起重器、框式高效退磁器、硅整流控制器等产品。

Since the motherboard with the soft, hard disk, such as the use of DMA operations between the peripheral, DMA operation of the response process is as follows (AST386 in the floppy disk to DMA as an example): floppy disk drive made by DREQ2 signal to the DMA controller (82C206), and DMA controller to the CPU (80386) issued HRQ signal, CPU end the current bus cycle after HLDA response signal to the DMA controller, DMA controller issued a final response signal DMA to the floppy disk drive DACK2 allow its data into the system bus.

由于主板与软、硬盘等外设之间采用DMA操作，DMA操作的应答过程如下(以AST386中软盘DMA为例)：先由软盘驱动器发DREQ2信号给DMA控制器(82C206)，然后DMA控制器向CPU(80386)发HRQ信号，CPU结束当前总线周期后发响应信号HLDA给DMA控制器，最后DMA控制器发DMA响应信号DACK2给软盘驱动器允许其数据进入系统总线。

Cluster of disk space is allocated for the unit, as the disk is a disk cluster distribution, release, read out the smallest spatial unit, even if only one byte of the documents have to occupy a whole cluster of disk storage space.

磁盘空间是以簇为单位进行分配的，由于磁盘簇是磁盘进行分配、释放、读出的最小空间单位，即使只有一个字节的文件也要占用整整一个簇的磁盘存储空间。

For example, hard disk 1gb only sub-district, then the cluster size is 32kb, that is to say, even if a file is only 1 byte long, 32kb storage must also account for the hard disk space, and the remaining space will be where all the idle, so has led to great waste of disk space. greater support fat16 partition, the disk capacity of each cluster is also greater, resulting in greater waste.

例如1gb的硬盘若只分一个区，那么簇的大小是32kb，也就是说，即使一个文件只有1字节长，存储时也要占32kb的硬盘空间，剩余的空间便全部闲置在那里，这样就导致了磁盘空间的极大浪费。fat16支持的分区越大，磁盘上每个簇的容量也越大，造成的浪费也越大。

Hard work in time to avoid the shock of it, because the distance between head and disk very close to, if clustering was head of the shock will lead to knock disk may be scratched disk heads, but also may lead to the total head count of the bad, the entire hard disk can not be used.

在硬盘工作的时候要尽量避免它的震荡，因为，磁头与磁片的距离非常近，如果遭到聚类的震荡会导致磁头敲打磁片，有可能磁头会划伤磁片，也可能会导致磁头的彻底算坏，使整个硬盘无法使用。

In my opinion, the simplest approach is: Normally, the hard drive to back up a partition table (not, to find a model with the same hard disk partition table can be), the event was to get rid of a hard disk, floppy disk with both fixed, it can be hard in the bios will set none, to start after the backup to restore the partition table back to the hard disk and then change the settings back from the new start, fdisk it.

我认为，最简单的办法是：在平时，将硬盘的分区表备份一个（没有的话，找一个与之相同型号的硬盘的分区表也可以），万一硬盘被干掉了，用软盘都起不动的话，可以在bios里将硬盘设为none，启动后，将分区表的备份恢复回去，然后将硬盘的设置改回来，从新启动，fdisk就可以了。

This process is usually performed by the disk's manufacturer , resulting in what are known as formatted disks. Most computer systems can also perform this task. Thus, if the format information on a disk is damaged, the disk can be reformatted, although this process destroys all the information that was previously recorded on the disk.

轨道和扇区的位置不是磁盘的物理结构的固定部分，它是是经由过程称为磁盘格式化或初始化形成的，它通常是由磁盘的厂家完成的，如许的盘称为格式化盘，大多数的计较机系统也能执行这一个任务。

As the root user, when you use the format utility and select a disk to partition, a copy of the disk's partition table is read from the label on the disk into memory and is displayed as the current disk partition table.

当你使用format命令时，format将读取这个文件(/etc/format.dat )。这个文件是一个可用磁盘类型的表和一个预先定义的分区表的集合，你能用它来快速分区磁盘。
