硬盘分区打不开,用PQ也不能格式化,提示"错误#45,CRC error in data...

这样吧：首先4分区都存在你下载HDTune-V2.50.exe百度下很多！检测下硬盘是否有坏道！
如果真的是物理损坏，估计用普通手段恢复的几率比较小（读盘机费用较贵）。

建议：

1.先备份坏盘的分区表

2.用数据恢复软件（如 FinalData 2.0和EasyRecovery Professional 6.10 之类），最好挂双硬盘

3.也可以用ghost之类的软件把坏盘进行克隆并存为文件，再进行恢复所要文件

硬盘坏了是小事 重要资料一定要救回来！

祝：节日愉快！

1，中毒，分区表信息被破坏了，
2，不正常关机度致数据丢失。
尝试用分区魔法师，将那个问题区删除后，再重新划分，
如果windows状态还是没办法处理，只有用XP盘在安装信息那里将问题分区删除再重新划分。
第二种方法，有可能会引致全硬盘数据丢失，小心。

答啦，给我上回一样，整个GHOST盘用上面的PQ全部再分区吧。不行的话，把你的硬盘挂别的机子上当从盘再整一定行。

坏道吧，用效率源修复吧

symantec的官方解答：
This problem is often caused by bad sectors on the hard drive.

To resolve the problem

1. Run ScanDisk (in Windows 9x/Me) or CHKDSK (in Windows NT/2000/XP) to perform a thorough surface scan of the disk.
This flags any bad sectors on the disk so that they cannot be used in the future.
2. Reinstall the software that you were using when you saw the error message to ensure that none of the program's files are corrupted.

If the error still occurs after you have done this, try any of the following:

* Update the product to the current version.
* If your computer has two IDE hard drives that share the same cable, try connecting the drives using separate cables.
* If the error is the result of a corrupted file, you can identify the affected file by running your program (PartitionMagic, DriveCopy, Drive Image, etc.) at a command prompt using the /dbg switch (debug) and sending the results to a text file. When the error occurs again, the name of the file that was being read at the time that the error occurred is written to the text file. After you have identified the corrupted file, replace it with a good backup copy of the file, if possible.
* If you were using DriveCopy when you saw the error, try rerunning DriveCopy at the command line using the /ire switch (Ignore Redundancy Errors).

问题原因可能是磁盘分区坏道
里面可以操作的几个方法：

1.尝试用chkdsk工具，修复受损分区，运行：chkdsk /f F:
2.如果你的计算机上是两个IDE设备共用一根数据线，可以把它们分开，分别接到主板上。（个人认为现在这条基本可以无视）
3.可以尝试用命令行方式运行PQ，加上参数/dbg,(即debug，我猜也可以用建立快捷方式，在快捷方式里添加参数的方法运行)，程序会查看是哪儿出了问题并写进一个txt文档里面，然后可以使用其他工具将有问题的文件删除
