Hi. I have come across a problem to get Hard disk serial number. I’m googling it from past one week without much joy. I found many solutions. None of them were perfect. The most common problem, which I faced, is that the Hard disk serial number couldn’t be taken without admin permission in Vista. In Microsoft website the api is given which will return the Drive volume serial number. The problem is that once we format the hard disk the drive volume serial number will change. The other option is to use SCSI back door. But it is not available in Vista. The only option remaining is using S.M.A.R.T.. The Smart api doesn’t work properly in VB without admin permission. But it is possible in an exe created in VC++, where they read the hard disk code without admin permission. Is there any other method in VB where the Hard disk serial number and model number can be read?
