On unix-like systems, you'd be able (only as root, most likely) to read the disk files /dev/{h,s}d* and write whatever byte sequence you want to them, including byte sequences that represent a, say, ext3 file system.
I don't know of any ext3 libraries in Java, though, so you might have to write it yourself. Or a library for the file format you care about.
This is probably not what you want, though, but you can settle for it :-)

这是非常特定于系统的，没有通用的方法来执行此操作。您的选择是
It is very system specific, there is no universal way to perform this. Your options are
不直接。您将需要调用操作系统特定的程序来为您完成实际工作。
Not directly. You will need to invoke a operating system specific program to do the actual work for you.
在类 Unix 系统上，您能够（最有可能仅以 root 身份）读取磁盘文件
/dev/{h,s}d*并写入您想要的任何字节序列，包括代表 ext3 文件系统的字节序列。不过，我不知道 Java 中有任何 ext3 库，所以你可能必须自己编写它。或者您关心的文件格式的库。
不过，这可能不是您想要的，但您可以接受:-)
