Before Windows Vista and Windows 7, you cannot shrink or extend partition in Disk Management, so you may convert a basic disk to dynamic to extend partition, but nowadays many people want to convert dynamic disk to basic.

When you add new disks, you may convert disk to dynamic mistakely. To convert dynamic disk to basic disk, Microsoft provides no method, it tells you to delete all dynamic volumes and then convert dynamic disk to basic disk, bad enough.

Fortunately, there are other methods to convert dynamic disk to basic without data losing.

Why convert dynamic disk to basic disk?

Although dynamic disks contains  many advantages than the basic disks, it also brings some problems as bellow:

1. If you converted basic disk to dynamic, you cannot delete these dynamic volumes and reinstall Microsoft Windows operating system with system CD/DVD.

2. You cannot convert dynamic disk to basic disk without data losing in Disk Management, as you need to delete all dynamic volume firstly before converting.

3. In most conditions the dynamic volume still cannot be extended, especially for the system and boot volume, many people would encounter this problem if they need to increase dynamic disk. But due to the limitation of Disk Management, only Simple Volume and Spanned Volume can be extended.

Nowadays, the hard drive price is lower and lower, you may purchase larger hard drive and hardware RAID card for high performance, you don't need dynamic disk again for higher computer performance.

Other problems you should know

  1. Though Windows Vista, Windows Server 2008 and Windows 7 can expand partitions, the precondition is that there is unallocated space behind the partition you want to expand. If there is no unallocated space there, you can still choose 'Extend' partition command, but Disk Management will convert basic disk to dynamic.
  2. On basic disk, you can create only 4 primary partitions or 3 primary partitions plus an extended partition, if you want to create more partitions in Windows Vista, Windows Server 2008 and Windows 7, you have to convert basic disk to dynamic.

No matter you are using dynamic disk originally or convert basic disk to dynamic mistakenly, there are still ways to convert dynamic disk to basic without data losing.

How to convert dynamic disk to basic

Convert dynamic disk to basic via dynamic disk converter, it is able to convert dynamic Simple Volume and Mirrored Volume directly to basic disk. To other dynamic disk volumes, you can copy to another basic disk.

Alternatively, you may keep using dynamic disk, when there is one volume running low, you can change the volume size with dynamic disk manager.

    My sons have an HP one year old laptop running Vista Home Premium 32 bit. Of course, just turned a year old two days ago and warranty is now up. There is not a lot of software on this thing. I installed ESET Nod32 and it runs well. I just scanned and there are no threats found. No popups are appearing in IE. There is no sign of a virus anywhere. There are multiple problems that I cannot figure out. When we try to shut the computer down, it gets stuck in Logging Off screen. I try Ctrl Alt Delete to bring up Task Manager but it will not appear. I get the Icon down in the lower right part of the screen, but cannot click on it to open it up. I tried to do a System Restore. I select it, but nothing happens. When I try doing it all over again, it says that it is already running, but it is not. I have tried uninstalling things they dont need but the uninstall freezes up also and when i hit cancel, it just remains cancelling without doing anything. I am usually pretty good at fixing things but this one has me stumped. If I could just do a restore, i feel like i could get it back to where it was before this started happening a couple of days ago,. Any help is appreciated.

    Did you try to enter safe mode to uninstall the application that cause this problem?
    Do you have Windows installation CD, you may try to repair it.
    HP has a partition for restoring, to run it normally, you should check whether you have changed the drive letter of this partition, then press ESC to restore.
    If you still cannot solve the problem, you may conact support@www.hdd-tool.com with detailed information and some screenshots.
