PowerShell Lists all the disk space

Hi All,

I'm new to PowerShell and struggling to find a way forward with using the win32_logicaldisk class within my basic script.

I need all the disk results sent out to the body.
But the letter is received blank.
one disk is not the problem.
The results are as follows in mail.

磁碟機代碼：C:
磁碟機名稱：
磁碟機大小：231.6 GB
剩餘的空間：87.6 GB
已用的空間：143.9 GB
已用的比例：62%

Two disk errors.

Method invocation failed because [System.Object[]] doesn't contai
n a method named 'op_Division'.
At C:\Users\Administrator\Desktop\test.ps1:11 char:1
+ $body = "磁碟機代碼：{0}" -f $Disks.DeviceID + "`r`n"+
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (op_Division:Str 
   ing) [], RuntimeException
    + FullyQualifiedErrorId : MethodNotFound

Hope someone can help.
