Question

我正在创建一个批处理文件，以用真实数据完全填充USB驱动器，SD卡，Micro SD卡等上的剩余可用空间，以防止恢复以前删除的文件。设备。

背景：我有一个简单的PNY品牌的16GB SD卡，上面装有狩猎相机拍摄的静态照片。我使用Windows 8常规删除方法删除了照片。然后，我使用了Windows 8格式功能（取消选中“快速格式”选项），该功能应该可以安全地擦除数据。接下来，我在选择的驱动器上运行DiskDigger.exe程序，它检索了每张照片。然后，我运行Privazer.exe并在SD卡上执行了3 Pass DoD覆盖。尽管如此，DiskDigger仍检索了每张照片。再尝试几次将数据复制和粘贴到卡上，然后运行安全的擦除程序以删除数据，仍然可以检索照片。我无法获取照片的唯一方法是用一个128字节的文本文件覆盖SD卡上的最后一个字节，该文本文件会重复复制直到满。重新格式化驱动器后，照片将无法恢复。

很抱歉，但很详尽，但希望每个人都知道确切的问题。

我想要什么：

.bat文件覆盖媒体上可用的每个字节的可用空间
覆盖数据将来自同一DIR中包含的一组.txt文件
一旦执行，我根本不希望.bat文件提示用户
我不想将.bat文件运行到出现磁盘已满错误的地步
我希望它能够处理多达64GB的可移动驱动器

我所拥有的：

F：恰好是我特定的USB驱动器号
毫无疑问，这离高效有数百万英里之遥，但我当时正在用一种使事情起作用的方法。一直到我获得“达到的递归SETLOCAL限制”（但是，它已填满驱动器）
我首先使用.bat文件生成每个标准大小的.txt文件并使用我的覆盖.bat文件将它们加载到同一目录中。看来我无法使用批处理复制大于2GB的文件。因此，我创建了8个不同名称的2GB文本文件至少可以覆盖16GB的SD卡。我遇到的另一个问题是提示用户确认覆盖相同文件名的提示。一世还没有想出如何克服相同的文件名提示。
我必须放置所有SETLOCAL才可以将For语句准确读取剩余的可用空间。没有他们，自由空间变量在每次迭代中均保持不变。

我知道有更好的方法，但是请原谅，这就是我想要的帮助。有人可以

告诉我如何正确循环播放
如果可能，请告诉我如何在不提示用户的情况下强制重复文件名仍然进行复制。这样可以避免我不得不创建32个不同名称的2GB .txt文件来覆盖64GB驱动器。
我知道这很基本，但是是的，我希望批量生产它。

该.bat文件应该从驱动器中读取可用空间，复制将适合该空间的最大.txt文件，重新读取可用空间，复制最大的.txt文件，依此类推...直到完全填满无需用户输入即可将驱动器减小到128字节的空间，并且不会出错。

文件运行

Answer 1

我想出了一个可行的解决方案，可以完成用真实文本数据覆盖可移动媒体上的可用空间的任务。 .bat程序从头到尾在我的笔记本电脑上运行，没有用户输入或错误。

我通过USB卡适配器使用空白的16GB SD卡，再次比较了CCleaner的运行时间。

我的.bat文件花了33分钟的时间才用文本数据完全填充SD卡。
在“ 1次伪随机数据”上设置的CCleaner花费了32分钟。

与大型商业品牌的比较给我留下了深刻的印象。我知道这个.bat文件正在将数据写入驱动器上的每个可用空间；但是，我对1遍伪随机CCleaner所做的事情并不满意。我也可以放心，此.bat文件不会拨回家，收集用户数据或保留有关我的统计信息。这是我选择编写.bat文件而不是与他人的商业品牌一起使用的原因。没有广告，没有弹出窗口，没有隐藏的互联网连接，等等。

如果有人想实际使用该程序，我可以发布一个.bat文件的副本，该文件用于生成我的特定大小的.txt文件，这些文件用作填充数据。只是给我发消息，我会尽快与您联系。

以下是我的.bat程序。我尽我所能评论它。我仍然对缩小或精简它以提高效率的建议持开放态度。我不是专家，这就是我现在批量处理的地方。最后，时间计算不正确。我想您不能简单地从结束时间中减去开始时间。我会努力的。没错。
