今天我尝试将旧的希捷^(Seagate)外置驱动器连接到我的Windows电脑，但发现我无法访问它。当我连接它时，在计算机^(Computer)文件夹中，绿色条一直在加载，当我尝试右键单击这个驱动器号时，圆圈一直在旋转。我觉得我可以再次开始使用外部驱动器的唯一方法是检查它是否存在磁盘错误并在需要时对其进行格式化。

外置硬盘无法访问

如果您遇到这种情况，发现您的USB或外部硬盘驱动器无法访问，那么本教程将为您提供帮助，因为它展示了如何使用CMD或命令提示符^{(Command Prompt)}检查磁盘是否有错误并格式化它，并希望成功地重新访问它。

使用 CMD 运行检查磁盘

使用Windows 8中的WinX 菜单^{(WinX Menu)}，打开提升的命令提示符窗口并键入以下内容：

chkdsk /f E:

这里 E 是USB或外部驱动器的盘符 - 或任何驱动器 - 您想要扫描错误并在发现错误时修复错误。因此，请确保将其替换为您的情况下的正确字母，小心谨慎，然后按 Enter^(Enter)。

检查磁盘^{(Check Disk)}操作将在驱动器上启动，它还将修复可能发现的任何错误。

在我的外部驱动器^(Drive)上成功完成检查磁盘^{(Check Disk)}后，我发现我能够访问它。

使用 CMD 格式化驱动器

然后我备份了数据^{(backed up the data)}并决定对其进行格式化。要使用CMD^(CMD)格式化驱动器，请键入以下命令，然后按 Enter^(Enter)：

format E: /fs:ntfs

同样，这里的 E 是您要格式化的USB或外部驱动器的字母。^(USB)因此，请确保在您的情况下小心地将其替换为正确的字母。确定后，按 Enter^(Enter)。您也可能会被要求输入磁盘标签^{(Disk Label)}。键入它并再次按 Enter^(Enter)。

磁盘格式化将开始。

CHKDSK 停止响应

如果您遇到CHKDSK停止响应并且无法从文件损坏中恢复的情况，当您在Windows中运行^(Windows)CHKDSK /SCAN命令时，您可以运行系统文件检查器^{(System File Checker)}并查看它是否有帮助。或者，您可以从KB2906994下载修补程序并将其应用到您的Windows计算机。

附加信息：命令行检查磁盘选项^{(Command Line Check Disk Options)}。

希望有一天这对你有所帮助。^{(Hope this helps you someday.)}

External hard drive inaccessible? Format or run Check Disk using CMD

Today I tried to connect my оld Seagаte external drіve to my Windоws PC after a long time and found that I was just unable to аccess it. When I connected it, in the Computer folder, the green bar just kept loading, and when I tried to right-click on this drive letter, the circle just kept whirling round and round. The only way I felt I could start using the external drive again was to check it for disk errors and format it if required.

External hard drive inaccessible

If you face such a situation, where you find that your USB or external hard drive has become inaccessible, then this tutorial will help you as it shows how you can check the disk for errors and format it too, using CMD or the Command Prompt, and hopefully, succeed in getting back access to it.

Run Check Disk using CMD

Using the WinX Menu in Windows 8, open an elevated command prompt windows and type the following:

chkdsk /f E:

Here E is the letter of the USB or external drive – or any drive for that matter – where you would like to scan for errors and repair the errors if found. So make sure you replace it with the correct letter in your case, carefully, and hit Enter.

The Check Disk operation will start on the drive, and it will also repair any errors which may be found.

Once Check Disk completed successfully on my External Drive, I found that I was able to access it.

Format Drive using CMD

I then backed up the data and decided to format it. To format a drive using CMD, type the following command, and hit Enter:

format E: /fs:ntfs

Again, here E is the letter of the USB or external drive which you want to format. So make sure you replace it with the correct letter in your case, carefully. Once you are sure, hit Enter. You may be asked to enter the Disk Label too. Type it and hit Enter again.

Disk formatting will commence.

CHKDSK stops responding

If you face a situation, where CHKDSK stops responding and cannot recover from file corruption, when you run the CHKDSK /SCAN command in Windows, you may Run System File Checker and see if it helps. Or else you could download hotfix from KB2906994 and apply it to your Windows computer.

Hope this helps you someday.
