u盘写保护怎么办?U盘,现在最流行的移动存储设备,很多朋友都靠它在转移自己需要的资料信息,但有时也会带给我们一些烦恼,u盘写保护怎么办了,U盘不能修改内容,不能删除文件,其实关于u盘写保护删除是非常简单的,哪下面就让小编给大家介绍一下u盘写保护删除的解决方法。
1.到系统目录 C:\WINDOWS\system32\drivers 看有没有一个 sptd.sys 的文件。删除它,重新启动。问题解决!注意:这个sptd.sys不是微软Windows自带的。(可能是安装Daemon Tools装上的)
2.1. 系统里有映射的网络驱动器。导致该盘符不能分配给磁盘.
解决办法:断开映射的网络驱动器.
3.盘符被隐藏。
解决办法:进入注册表(regedit.exe),进入“HEKY-CURRENT-USER\Software\microsoft\windows\currentversion\policies\explorer"分支。找到该路径存在的键值“NOdrives”,将其删除。注销然后重新登陆。 (不是 NoDriveTypeAutoRun 键值).
4.磁盘不格式不正确
一般的U盘是使用HD(硬盘FAT16)格式,如果使用U盘启动程序更改,可能U盘格式不正确。请使用PQ、PPM等硬盘分区软件重新分区;
5.usb移动存储设备被禁用
请保证:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\usbehci] "start"=dword:00000004
6.U盘出问题
解决办法:重新格式化U盘。最好低级格式化,到网上找一个磁盘工具。
如果不能格式化,就需要低格或量产来解决了,方法如下:
一、下载U盘芯片检测工具"芯片无忧",得到问题U盘的芯片;
二、搜索该芯片的低格工具或量产工具,并下载;
三、低格或量产。
7.解决办法:右击“我的电脑”,在弹出的快捷菜单中选择“管理”命令,进入到“计算机管理”窗口,依次展开“存储/可移动存储”,单击“磁盘管理”一项,在窗口右侧,看到U盘运行状态为“良好”,这说明磁盘没问题。右击该窗口中的磁盘盘符,选择其快捷菜单的“更改驱动器名和路径”命令,在出现的对话框中,点击〔更改〕按钮,为其选择一个未被使用的盘符。确定之后退出。重新打开“我的电脑”,久违的磁盘盘符出现了。 www.upan.cc
还有两种可能!
第一。权限问题,您不是管理员用户(极有可能)
第二。服务及组策略里未开启!
