fetch DriveGetDrive to array

[autoitxp]

       Global $RemDL
       Global $dt[0]

    $RemDL = DriveGetDrive($DT_FIXED)
    If  NOT @error Then 
    For $i = 0 To UBound($RemDL) - 1
        ReDim $dt[$i + 1]
        $dt[$i] = StringReplace(StringReplace(StringUpper($RemDL[$i]), "C:", ""), "F:", "")
        If $dt[$i] = "" Then ReDim $dt[$i - 1]
   Next

    _ArrayDisplay($dt)

endif

Trying to get fix drives as array in proper manner got 4 drives (c: d: e: f:) but getting  5 rows as array which i want to display as 2 drives (2 rows) only d: and e:

Not really sure what you're trying to achieve, but maybe something like:

#include <Array.au3>
Global $RemDL
Global $dt[0]
$RemDL = DriveGetDrive($DT_FIXED)
If @error Then Exit
For $i = 0 To UBound($RemDL) - 1
    If $RemDL[$i] = "C:" Or $RemDL[$i] = "F:" Then ContinueLoop
    _ArrayAdd($dt, $RemDL[$i])
Next
_ArrayDisplay($dt)

Thanks ! 

#include <Array.au3>

Global $RemDL
Global $dt[0]

Func _DriveR()
    $RemDL = DriveGetDrive($DT_ALL)
    If @error Then Return SetError(-1)
    For $i = 1 To UBound($RemDL) - 1
        If $RemDL[$i] = "A:" Or $RemDL[$i] = "B:" Then ContinueLoop
        _ArrayAdd($dt, $RemDL[$i])
        If @error Then Return SetError(-1)
    Next
    If UBound($dt) = 0 Then Return SetError(-1)
    Return $dt
EndFunc   ;==>_DriveR

Subz 
what if i don't need to use _arrayadd as _arrayadd use redim in loop  any other way to delete array and fetch correct array on call 

[Subz]

Number of ways, _ArrayDelete and ReDim

#include <Array.au3>

Global $aAllDrives = _Example1()
_ArrayDisplay($aAllDrives)

Func _Example1()
    Local $aAllDrives = DriveGetDrive($DT_ALL)
        If @error Then Return SetError(-1)
    _ArrayDelete($aAllDrives, 0) ;~ Remove the first row
    For $i = UBound($aAllDrives) - 1 To 0 Step - 1
        If $aAllDrives[$i] = "A:" Or $aAllDrives[$i] = "B:" Then _ArrayDelete($aAllDrives, $i)
    Next
    Return $aAllDrives
EndFunc

#include <Array.au3>

Global $dt = _Example2()
_ArrayDisplay($dt)

Func _Example2()
    Local $RemDL = DriveGetDrive($DT_ALL)
    Local $aDT[0]
        If @error Then Return SetError(-1)
    For $i = 1 To UBound($RemDL) - 1
        If $RemDL[$i] = "A:" Or $RemDL[$i] = "B:" Then ContinueLoop
        ReDim $aDT[UBound($aDT) + 1]
        $aDT[UBound($aDT) - 1] = $RemDL[$i]
    Next
    If UBound($aDT) = 0 Then Return SetError(-1)
    Return $aDT
EndFunc   ;==>_Example2

@Subz First example is good as not using redim in loop thanks 

[BrewManNH]

_arraydelete uses ReDim internally. Almost any array UDF that resizes an array, by adding or deleting some row/column will use it.

There are better ways to do it, namely by copying the array to another array, and not copying the parts you don't want. Then return the copied array.

if you can put  code here by using @Subz _example1(). 

[BrewManNH]

Why? How many drives do you have that would affect the speed of your code that much such  that any reduction in speed by using ReDim would shave off nanoseconds?

[autoitxp]

its loop to check fixed drives and fixed labels  almost 500.  drives keep coming online and going my I am trying to get array of drives at gr8 speed as possible some of drives also need to block from displaying as above example A: AND B:
