I'm developing a system info application. I've Searched all over internet and only found code for Free Hard Disk space, but not Total hard disk space.
The code should calculate the Total space of all the drives.
how to write a null bytes onto unused hard disk spaces? I understand that files deleted are still existed on hard disk, I am thinking of may be if I write the null bytes to every single unused bytes so that the unused hard disk space would be become all null bytes, and unused space would no longer contain of those deleted files.

View 2 RepliesI have a program that must copy a file to 3 locations, the local hard disk, a USB drive, and a network location. I have the file (about 70mb) loaded into a byte array. My quesion is, since I'm not actively modifying the byte array, can I impliment a form of multithreading where all 3 threads read the same byte array at the same time?
View 1 RepliesI am working with VB 2008. I want to be able to run this program say in N: and it will show me in an excel sheet the following:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
where clients contains subfolders and files and the size is the total of all those files within each folder and the count is the total within each folder also.
This works fine as it is but i have to select one by one the top level folders and some of them are huge so it takes forever to give me an answer.
1) I would like to see in my spreadsheet the following by only select the network drive n:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
N:Software 10.7 15430
N:Billing 0.98 105
2) I would also like to know if this is the faster method.
3) I tried adding a progress bar so that the user can have an idea of how much this will take but i had to remove because it was not working.
4) I would like to see the folder name, size of folder and count of files in the listview.

The drive is connected via USB and the problem I'm having is that, periodically, while my code is executing, the usb drive seems to disconnect and reconnect. (Nothing to do with the program, but the drive itself).I want to find a way to prevent these temporary drive reconnects from interrupting my code. IE, i want to insure that whatever read or write that is requested is actually executed even in the case of a temporary drive interruption.
