Does the notebook have two hidden partitions? For example, HP has an HP_Recovery and an HP_Tools. A disk can only have up to four primary partitions, and the rest must be logical partitions. The default partition of Vista and Windows7 is the primary partition. If the number of partitions exceeds four, the basic disk will be automatically converted into a basic disk. It is recommended not to convert, because this conversion is irreversible, just like converting FAT32 file system to NTFS file system. This is equivalent to upgrading, upgrading is easier than downgrading! If you want to convert it back, you must format the disk. If you want to convert a hard disk that has been converted into a dynamic disk into a basic disk, you must format the whole hard disk, which means that all your data will be lost.

Dynamic disk has its advantages-the capacity of each partition can be adjusted at will, but it also has its disadvantages-it can't be loaded with two systems or multiple systems.

If you only use one operating system, then the conversion doesn't matter. Some time ago, Windows7 was installed under Vista, and I want to assign a separate partition to Windows 7. I just checked when I didn't want Win7, but when I installed Vista, the engineer had assigned me four partitions, and I was in the same situation as you. Now I don't think it's necessary to make so many partitions. If it is too much, it will be in trouble. I advise you not to partition. It is enough to have two disks, one is the operating system and applications, and the other is to store personal data. It will also avoid moving files between different partitions in the future, which is too slow. It only takes a few seconds to move a file in the same partition, no matter how big it is. It's just that the partition was not well divided in the past, but now Win7 is installed in F drive, and there is a lot of data at the same time, which is troublesome!

As for your compressed unallocated space, it can also be extended to other partitions, usually from the compressed place, that is, your C drive.

Finally, whether to convert it into a disk depends on your own use. It is best not to switch, so as to avoid irreparable trouble in the future.
