如何在C＃4.0中区分硬盘模型

Question

I am currently using a WMI query to return the manufacturer name of all hard disks connected to a computer. Unfortunately this doesn't specifically return "Intel" or "Western Digital" so I am using string.Contains() to compare who the manufacturer is. My code in simple form is:

        //*** Declare Management Class
        ManagementClass clsMgtClass = new ManagementClass("Win32_DiskDrive");
        ManagementObjectCollection colMgtObjCol = clsMgtClass.GetInstances();

        //*** Loop Over Objects

        foreach (ManagementObject objMgtObj in colMgtObjCol)
        {
            MessageBox.Show(objMgtObj.Properties["Manufacturer"].Value.ToString());
        }

This works maybe 60% of the time, because it relies on the WMI to return the whole name. So for example my hard drive is returned as "SanDisk SDSSDX240GG25 ATA Device" which is fine because I can locate "SanDisk" quite easily. Likewise, Western Digital products will show up as "WD3000USB" or something like that, where I can clearly find "WD". However on another computer using a Seagate drive, it has SE1000GXB blah blah and doesn't have any real indication of the manufacturer. So my question is, how could I reliably find out the hard drive manufacturer, and be able to easily differentiate between manufacturers without having to go to all the trouble of querying model numbers through a google script or database. Thanks. Another edit: using the member "Caption", it will return the examples above. Using the member "Manufacturer" will simply return "(Standard Disk Drives)"

Answer 1

ST - seagate

You could download a list of model number prefixes from each of the now merged hard disk companies and make a table out of the models, this table could contain the actual capacities as well if you wished.

Model numbers typically have enough information in them, serial numbers on disk devices after 1986 typically contain model information in them.

Bottom line, you may have to create a table to lookup the information in a human friendly way.
