# ONE-CLICK REPAIR FINAL FIX

## Additional Issue Found

**Error:** "Cannot bind argument to parameter 'Path' because it is null"
**Root Cause:** Wrong parameter name used when calling `Test-DiskHealth`

### Problem
**FILE:** Helper/WinRepairGUI.ps1
**LINE:** 2998
**ERROR TYPE:** ParameterBindingException
**ERROR MESSAGE:** Cannot bind argument to parameter 'Path' because it is null
**ROOT CAUSE:** Function `Test-DiskHealth` expects parameter `-TargetDrive`, but was called with `-WindowsDrive`. This causes the parameter to not bind, leaving `$TargetDrive` null inside the function. When `Test-DiskHealth` then calls `Get-Volume -DriveLetter $TargetDrive`, the null value causes the error.
**CONFIDENCE LEVEL:** 100%

### Fix Applied
**Before:**
```powershell
$diskHealth = Test-DiskHealth -WindowsDrive $drive
```

**After:**
```powershell
$diskHealth = Test-DiskHealth -TargetDrive $drive
```

### Additional Fix
Also fixed the same issue in `Helper/MiracleBootPro.ps1` line 1504.
