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 so-called when necessary, there are two, first, the factory hard drive, hard drive works on a low-level format the hard disk; the other is when the hard drive certain types of Bad Track, the use of low-level format to achieve a certain degree of the role of mitigation, or shielding.

而这个所谓的必要时候有两种，一是硬盘出厂前，硬盘厂会对硬盘进行一次低级格式化；另一个是当硬盘出现某种类型的坏道时，使用低级格式化能起到一定的缓解或者屏蔽作用。

Mobile hard disk can not move at will, mobile hard disk and lead plane jumper are general at least a few centimeters, a lot of people copy data at the same time actually, take at the same time in the hand, this is the error with the commonnest you, experience is fluky, your so harum-scarum behavior accumulative total has the possibility 10 times, 30, did not give a business on the spot, but hard disk of day of very possible abrupt some was hanged ahead of schedule, life of normal circumstance hard disk should be more than 35 years, be like what write above advertisement to have average time to failure, allegedly tens of thousands of hour, it is not quite clear that I am written down, when this plaything high speed runs, anyhow must place the platform that stabilizes in to go up.

移动硬盘并不能随意移动，移动硬盘和主机连接线一般至少几十厘米，很多人竟然一边拷贝数据，一边拿在手里，这是诸位最常见的错误，经验并不可靠，可能你这样鲁莽的行为累计有十次，三十次，从来都没当场出事情，但很有可能忽然某一天硬盘就提前挂了，正常情况硬盘寿命应该不止三五年，好象广告上面写的有平均无故障时间，据说几万个小时，我记不大清楚，总之这玩意儿高速运转的时候必须放置在一个稳定的平台上。

This paper examines the soil characteristic and liquefaction degree of hard shell seams at the subaqueous delta of the Yellow River. Four typical areas were chosen for measuring, testing and studying. The hard shell seam strength was measured by in-situ Proctor penetrometer. Undisturbed soil sample of 1 m long was excavated for laboratory soil property test. Sledge hammers were dropped down freely to hit the load board to simulate the wave force acted on the hard shell seam. The excess pore pressure and strength variation were observed. The liquefaction depth of the hard shell seams at four study areas under different wave storms were calculated by theory.

为揭示黄河口水下三角洲硬壳层的土性特征和风浪作用下的液化破坏状况，选择典型研究区，在现场利用普氏贯入仪测试硬壳层的强度特征，原位取1m原状样进行室内土工试验；利用重锤锤击荷载板的方式模拟波浪对硬壳层的动力作用，通过孔压探头和普氏贯入仪实时监测土体内孔压和振动前后强度的变化；通过理论计算研究硬壳层在不同风浪等级下的液化深度。

Zero once the damaged track will be the primary boot hard drive and the partition table information will be seriously damaged, resulting in the hard disk can not boot. 0 tracks damaged judge: System self-test pass, but the boot partition C disc lost or directory is missing, there are laws of the hard disk "... creak ... creak" seek the sound of running SCANDISK scanning C disk, in the first cluster a red "B", or can not find Fdisk the hard disk, DM died in the 0 track, the track such a situation that is zero damage!

零磁道一旦受损，将使硬盘的主引导程序和分区表信息将遭到严重破坏，从而导致硬盘无法引导。0磁道损坏判断：系统自检能通过，但启动时，分区丢失或者C盘目录丢失，硬盘出现有规律的"咯吱……咯吱"的寻道声，运行SCANDISK扫描C盘，在第一簇出现一个红色的"B"，或者Fdisk找不到硬盘、DM死在0磁道上，此种情况即为零磁道损坏！

To imagine such a situation, when you more than the amount of memory, and run a relatively large-scale process, will inevitably lead to a sharp reduction in the number of physical memory, and in this case the so-called "optimization software," the beginning of smart aleck, the data memory for paging to the hard drive, and the procedures needed for the operation of the data, which may have led to at the same time, the "optimization of software" tried to data paging to the hard disk, and the operating system attempts to read data from the hard disk into memory, a very large increase in hard drive read and write.

想象这种情况，当你内存数量不多，而又运行了比较大型的程序后，必然导致物理内存数急剧减少，而在这种情况下所谓的"优化软件"开始自作聪明，把占用内存的数据往硬盘上进行分页，而程序的运行需要这些数据，这可能导致了在同一时间内，"优化软件"试图将数据分页到硬盘，而操作系统试图将数据从硬盘读取到内存，极大增加了硬盘的读写。

At the same time, the hard disk will be issued by strange noises; startup hard disk can not boot system, boot with the floppy disk drive can be transferred to the hard disk, but can not access, use SYS command can not be successful conduction system; FORMAT the hard disk, to a certain progress does not stop before the last error, can not be completed; the implementation of the hard disk when FDISK, progress will be repeated to a retreat into advance and retreat.

与此同时，硬盘会发出异样的杂音；启动时不能通过硬盘引导系统，用软盘启动后可以转到硬盘盘符，但无法进入，用SYS命令传导系统也不能成功；FORMAT硬盘时，到某一进度停止不前，最后报错，无法完成；对硬盘执行FDISK时，到某一进度会反复进进退退。

Based on the relevant movement between hard shaper cutter and grinding wheel, the movements of grinding wheel are studied. The shaping grinding point and the shaping grinding edge are made up with. In order to easily compare when shaping errors and cutting edge"s angles are the most excellent, uniform expressions for convex curved rake face of hard shaping cutter and spatial cutting edge curve are separately developed. The distributions of new profiling cutter"s shaping errors and cutting edges angles are analyzed. The relevant grinding wheel and cam are designed. Due to this paper, a new profiling hard shaping cutter has been manufactured successfully. At last experiments are made to test the performance of hard shaping cutter and all kinds of precision of hard gear.
