最近真的感覺到XP的不行了,做很多事情都越來越沒有效率,因此把他升級到WIN7

別懷疑就是在2020年我再升級WIN7 

 

安裝完成後竟然發現我的外接硬碟在磁碟管理能看到,但是就沒有磁碟代號

如果強制安裝磁碟代號給它,系統就會說: "這項操作無法完成 因為磁碟管理主控台檢視不是最新的........"

 

搞了兩三天了,最後竟然是WIN7的問題,

節錄如下

Simple volumes may become inaccessible if a power loss occurs shortly after creation


This issue occurs because the configuration information for the new volume was not written to disk by the time the power loss occurred.

Cause


 
 

Symptoms


 

Consider the follow scenario.  In Windows 7, you create a new simple volume in Disk Management or DiskPart.exe on a non-removable disk.  If your Windows 7 system experiences a sudden power loss within a few minutes of volume creation, you may notice the volume you created before the power loss is inaccessible and is not assigned a drive letter when you power the system back on.

Additionally, in Disk Management the volume may not have a status (for example, "Healthy") or a file system type listed.  If you try to modify the volume in Disk Management, you may receive the following error message:

The operation failed to complete because the Disk Management console view is not up-to-date.  Refresh the view by using the refresh task.  If the problem persists close the Disk Management Console, then restart Disk Management or restart the computer.

 
 
 
 
 
 
 
 
 

微軟的解決方法節錄如下,簡單來說就是去「裝置管理員」磁碟機的分項,把無法掛載的磁碟機點選右鍵=>解除安裝,接下來就重新整理,

系統會重新發現你的磁碟機,然後就突然的可以用了!!!

If you are experiencing the issue described in the "Symptoms" section, reinstalling the volume will resolve the issue.  Please follow these steps to reinstall the volume.

  1. Open Device Manager.  You can access Device Manager by typing "Device Manager" or "devmgmt.msc" in the Start Search box.
  2. Once Device Manager is open, click on "Storage Volumes" to expand the Storage Volumes portion of the device tree.
  3. Under Storage Volumes, you should notice a volume listed as "Unknown device."  Right click on this device and choose "Uninstall."  When asked to confirm, choose OK.
  4. Restart the system if you are prompted to do so.  The volume should be accessible once the system finishes restarting.  If you are not prompted to restart the system, right click in Device Manager and choose "Scan for hardware changes."  Once the scan is complete and installation of the volume completes, you will be able to access the volume.

Note: If the power loss occurs within a few seconds of volume creation, in rare circumstances you may be prompted to format the volume after you follow the above steps.  If this occurs, the file system configuration was not written by the time the power loss occurred.  You may need to reformat or recreate the volume.
