最近有朋友跟小编说,在使用U盘的时候,提示u盘写保护。u盘写保护是什么意思呢?很多人都疑惑吧!其实U盘写保护相当于只读也就是说修改内容但不能保存。那么u盘写保护是什么原因呢?出现u盘写保护的情况,我们要怎么解决呢?下面,且听小编将娓娓道来!
一、U盘被写保护的原因:
U盘写保护是专门为防病毒而设计的,如果要解除写保护,上面一般有一个可以拨动的键,调试一下就行了。但是没有写保护开关,而你的U盘却提示写保护了,那就是你的U盘自身问题了。
二、解决写保护U盘的方法:
1、查看U盘存储的文件数目;
U盘通常格式的是256个,如果超过限定额度而导致U盘出现问题是有可能的。所以,查看该U盘的根目录下的文件数目是否达到最大值,是很有必要的。
2、查看U盘中是否有不正常的驱动程序;
选中我的电脑—属性—硬件—设备管理器—通用串行总线控制器,查看所有项目是否全部正常,如果有不正常,则需要更新驱动程序。
3、设置电脑
如果测试后发现U盘写保护只是在某特定电脑内显示,在其他电脑则是正常运行,这就说明U盘本身没有问题,是电脑的故障。具体步骤如下:
1.开始—运行—输入regedit—确定;
2.找到HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control和HKEY_LOCAL_
MACHINE\SYSTEM\ControlSet001\Control\这两项,在这两项里找到StorageDevicePolicies这个子项,设置WriteProtect值为0;
3.找到HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevice—Policies,新建一个DWord值,命名为WriteProtect,设置其值为0;
4.重启计算机,插入U盘即可恢复正常。
u盘写保护是什么?上述小编已经详细为大家解释介绍过了。u盘写保护原因及解决方法内容也提供给大家了,虽然U盘写保护是为了防病毒而设计,却也给很多用户带来了不便。如果遇到u盘写保护的情况的话,就按照上面的教程就解决吧,希望可以帮助到大家!
