working with windows disk volumes

1- In windows disk management, I can see more than one volume C: F:, etc..
is there a way to tell from windows if those volume are on one physical drive or separate drives?
2- If a C: volume is dynamic, it is easy to extend it,but when it is basic it is not possible to extend it without third party tools. So what would be the inconvenient if we make all C: volumes dynamic from the get go?
3- There is also the option of Shrinking a disk, what s the size limit that a volume can be shrunk ? and when it is shrunk would it leave unallocated space so that we can create another volume?

Thank you very much!

1. You cannot tell the physical layout if there is a RAID controller since it may present any number of LUNs on any number of disks.

2. You can extend basic disks just as easily as dynamic disks if space is contiguous, you should avoid using dynamic disks wherever possible since it's just another level of complication.

3. The limit is often set by unmovable files such as the pagefile, shrinking is from the right, e.g. CCCCCDDDDD can become CCCCCDDDDF but it cannot become CCCCCFDDDD (F=free space created), this is often frustrating since one wants to shrink D: to increase C: into contiguous space. Third party tools will fix that of course, normally offline.

1.IControl Panel > Admininstrative tools > Computer Management you'll find Disk management which graphically displays physical disks and logical partitions and volumes allocated. Typically the question is also can we see physical drives that are part of a raid volume - only if they are part of a software based windows raid array (not recommended) hardware based e.g. raid 1  arrays will be presented as one physical disk  in disk management typically showing the array name given in the raid management software interface.
2. Diskpart is a builtin  command line tools which will allow you to expand even the c volume in Windows 7Windows 2008 R2 and later. You could argue disk sizing is easier with dynamic disks typically like to keep at the least the C volume on a primary partition as a basic disk - adequately sized at 130048 MB  (127 GB) which will still allow for fairly straight forward recovery should the need arise and at this time leaves server and workstations with ample room to grow as long as you move workload e.g exchange or SQL user databases to another volume.
3. Typically you can not shrink a disk smaller than the already occupied disk space.. On the other hand you can regain precious disk space by un-installing no longer needed programs or by compressing certain directories

Disk0, disk1, disk2 etc. Each disk can have 4 primary partitions or 3 primary + 1 extended. So it is easy to detect your harddrive configuration
2- If a C: volume is dynamic, it is easy to extend it,but when it is basic it is not possible to extend it without third party tools. So what would be the inconvenient if we make all C: volumes dynamic from the get go?
Do not use dynamic drives. Converting once the drive onto dynamic state sets you into trap. As you would need a special tool to convert it back to basic drive. Better to get a tool such as Hard Disk Manager 11 or Partition Manager 11 by Paragon www.paragon-software.com and handle all hard disk management tasks with it.
3- There is also the option of Shrinking a disk, what s the size limit that a volume can be shrunk ? and when it is shrunk would it leave unallocated space so that we can create another volume?
Shrink option takes 50% of available free space on partition you want to shrink. For example you have 150GB partition and only 50GB is used. Then during shrink you will get only 50GB unallocated space. Depending on fragmentation and data allocation on disk this space could be less.
Better to get one tool that can do backup copy partitioning etc and perform maintenance when it is needed.
