0:00:02.820000 --> 0:00:06.660000
 In this video, we will go through the
 process of creating a simple disk

0:00:06.660000 --> 0:00:10.680000
 for testing file systems and file system
 behavior, which is very beneficial

0:00:10.680000 --> 0:00:15.220000
 and important when you want to test a
 new file system or study its behavior.

0:00:15.220000 --> 0:00:19.500000
 Rather than using a true disk or using
 a USB for such testing purposes,

0:00:19.500000 --> 0:00:23.740000
 we could benefit from using a virtual
 machine to do that, while use a

0:00:23.740000 --> 0:00:28.300000
 Windows 8.1 system and we'll create
 a virtual disk that we can use.

0:00:28.300000 --> 0:00:34.180000
 Let's go to Settings, Storage, and
 click the controller we want to add

0:00:34.180000 --> 0:00:40.340000
 the disk to. Now, let's click on this
 icon, which gives us the following

0:00:40.340000 --> 0:00:46.280000
 options. Create new disk, choose
 existing disk or Cancel.

0:00:46.280000 --> 0:00:49.940000
 Since we don't have an existing disk
 to select, we'll be creating a new

0:00:49.940000 --> 0:00:55.140000
 one. Let's also leave the default as
 it is, a VDI virtual disk image,

0:00:55.140000 --> 0:01:00.840000
 and next, we can make it a dynamic
 located or just a fixed size.

0:01:00.840000 --> 0:01:03.740000
 Let's leave the default setting as
 it won't actually make a difference

0:01:03.740000 --> 0:01:07.820000
 from inside. Next, let's name it.

0:01:07.820000 --> 0:01:10.340000
 I'm calling it Testing
 File System.

0:01:10.340000 --> 0:01:18.440000
 I'm also giving it 250 megabytes.

0:01:18.440000 --> 0:01:21.080000
 Make sure you change this
 one to megabytes.

0:01:21.080000 --> 0:01:23.660000
 You can, however, choose
 whatever size you like.

0:01:23.660000 --> 0:01:27.400000
 I chose this size as we're making a small
 disk, making it easier to track

0:01:27.400000 --> 0:01:32.140000
 and analyze. Let's go ahead
 and click Create.

0:01:32.140000 --> 0:01:36.120000
 Now that everything is properly set,
 let's click OK and we can now start

0:01:36.120000 --> 0:01:37.780000
 the virtual machine.

0:01:37.780000 --> 0:01:43.160000
 Again, this is extremely useful for
 testing purposes, especially if you

0:01:43.160000 --> 0:01:47.420000
 want to start copying files to study
 and understand file system behavior.

0:01:47.420000 --> 0:01:55.260000
 Let's now go to Manage
 and Format Our Disk.

0:01:55.260000 --> 0:01:58.360000
 Please note that this may take a little
 bit of time depending on the specs

0:01:58.360000 --> 0:02:00.000000
 of your computer.

0:02:00.000000 --> 0:02:04.100000
 Now, let's go to Disk Management.

0:02:04.100000 --> 0:02:07.980000
 Here we'll find a message notifying
 us that we have a new disk.

0:02:07.980000 --> 0:02:12.300000
 Let's leave it as an MBR disk since we're
 already using such a small disk,

0:02:12.300000 --> 0:02:16.740000
 so it's OK to leave it as is.

0:02:16.740000 --> 0:02:19.520000
 Here we have an unallocated disk.

0:02:19.520000 --> 0:02:22.460000
 Let's right-click and select
 New Sample Volume.

0:02:22.460000 --> 0:02:24.960000
 Let's leave everything as it is.

0:02:24.960000 --> 0:02:27.960000
 Now, let's choose a drive letter.

0:02:27.960000 --> 0:02:31.400000
 We need to make sure that this drive
 is not being used by something else.

0:02:31.400000 --> 0:02:36.880000
 Let's use A. Here we can name it.

0:02:36.880000 --> 0:02:38.700000
 I'll name mine Testing.

0:02:38.700000 --> 0:02:42.960000
 Let's also make sure that we're running
 a 4096, as this is the one that

0:02:42.960000 --> 0:02:47.660000
 I want to use. Let's also make sure
 we're not running a quick format,

0:02:47.660000 --> 0:02:50.360000
 as there should not be
 any data on this disk.

0:02:50.360000 --> 0:02:54.700000
 So, let's uncheck it, and now we can
 click the next button, and now we're

0:02:54.700000 --> 0:03:01.240000
 finished. As you can see, the disk is
 being formatted and now it is ready,

0:03:01.240000 --> 0:03:05.320000
 as we see here. Now we can start copying
 files and using this disk for

0:03:05.320000 --> 0:03:10.120000
 testing purposes, especially
 for an NTFS disk.

0:03:10.120000 --> 0:03:13.200000
 Should you want to change the
 file system, you can do so.

0:03:13.200000 --> 0:03:17.840000
 Simply go to Format, here I'll
 enter FAT32 as an example.

0:03:17.840000 --> 0:03:21.700000
 Now, we can go ahead and format and
 use the cluster size you want.

0:03:21.700000 --> 0:03:24.440000
 Now we can test that one, etc.

0:03:24.440000 --> 0:03:28.380000
 As you can see, using a virtual machine
 and creating a virtual disk is

0:03:28.380000 --> 0:03:32.620000
 very useful when we're using and testing
 NTFS file systems or even other

0:03:32.620000 --> 0:03:39.140000
 file systems. And this concludes our
 video lesson on creating testing

0:03:39.140000 --> 0:03:43.120000
 file systems. We'll have a chance to
 use what we learned here soon, as

0:03:43.120000 --> 0:03:47.060000
 we will be depending on this type
 of activity in upcoming videos.

0:03:47.060000 --> 0:03:47.880000
 Thanks for joining us.
