This code is fine & there is no exception But " Supports Writing " is not showing . It shows only " Random Access " & " Supports Removable Media " both for my logical & virtual drive... Thanks for your long support :) But "Supports Writing" are still not showing... please... Thank you once again :)

Thanks for your support. I am using first time System.Management ; So I think i first read about this namespace, if you recommended any article ar link will help me & then I properly understand what is my mistake, & what is the way to solve this problem. I look this article which is written by Kirtan Pattel http://www.c-sharpcorner.com/UploadFile/kirtan007/2541/ but it is not working in my computer Is it need any special configuration? Thank you!

Perhaps CapabilityDescriptions does not always work; I don't know but it seems to not work for me either. So use "Capabilities" instead; it is an array of UInt16 numbers. Look in that array for the value 4, which indicates that the drive supports writing. If there is no 4, then the drive cannot write.

Sir if you have a little time for me, can you please put here a code. I am not able to do so that I want. Please Sir. Thank you in advance!

Sam Hobbs · Answer

This type of data is usually available using WMI so look at the System.Management Namespace; especially the ManagementClass Class. The online MSDN makes it difficult to find some things, but look for the "Win32_" WMI class for physical drives. The logical drive class might work.

Tanmay Sarkar · Answer

Sorry, you could not get my point. I want to check this property by C# coding not manually. Thanks for your post but it's not.....

Go to My computer -> right click and go to Manage -> computer Management will open -> there you go and click DEVICE MANAGER --> there you can find cd drive icon -> it is displaying DVD/CD - ROM DRIVES --> select this and open the tree --> if your cd drive has write permission means it will display like this -> CD ROM suppose it is displaying -> RW means your drive has both read and write
