为什么fdisk会有W95 Ext'd (LBA)这种文件格式?

以上是安装后fdisk结果
w95 ext'd是windows文件格式吗?Sample Text

Nope. It simply states that your 4th partition is an extended partition instead of a primary partition. The partition info in stored in MBR. However, the MBR can only store four partition entries. If you want more than four partitions, you will have to create an extended parition and with in which you can create more. In your case partition 5,6,7,8

wildlily980

您的意思:>4 partion就会有这个吗?
看起来像windows95 扩展分区的意思.

briangao

That is correct. If you want more than 4 partitions, you must have an extended partition first and then "sub-partitions" inside it.

不是文件格式。我认为应该称作分区表中的 分区 ID

这仅仅是分区的一个识别符。具体如何识别，取决于操作系统。

谢谢两位。
