Detectar unidades de disco duro
 

Saludos a todos.

Necesito de su ayuda para poder realizar una pequeña aplicación que detecte los diferentes discos duros que tenga una computadora o servidor, ya sea un solo disco duro o dos o tres o hasta cuatro en el caso de los servidores y que de arroje los datos básicos, como capacidad de cada disco duro, numero de serie, espacio utilizado y espacio libre, fabricante, tipo de partición, etc.

Alguien me podria decir como poder realizar dicha actividad.

Espero haberme explicado bien.

De antemano muchas gracias.

A ver si te sirve esto del compañero Neftali.

Si no deseas instalar componentes (que en este caso te facilitarán el trabajo) puedes usar directamente cósigo para acceder a WMI.

Creo que el ejemplo que hay en esta entrada es justo lo que necesitas.
https://neftali.clubdelphi.com/wmi-introduccion/

Ahí puedes obtener todos los datos que necesitas a través de WMI de la clase para discos duros Win32_DISKDRIVE;

Eso sí, debes modificarlo porque ahí sólo consulta el primero. Debes añadir un WHILE/FOR para que recorra todos los existentes.

Si usas los componentes eso ya lo tienes solucionado y el resultado ya lo puedes obtener como un objeto de una clase.

Código Delphi [-]

  TDiskDriveProperties = class(TPersistent)
