Partitions and disk.

In this practice we have to get the name of the hard disk and its partitions in different computers: in a Raspberry Pi, in Linux and in Windows. Also we have to compare computers both x86 and x86-64 architecture. Every hard disk of each computer has different partitions from the rest.

 

32-BITS COMPUTER

Here we analyze a 32 bits computer of the class with the help of hirens boot cd and its tools that you will see.

1)Windows

To get here you only have to boot your computer with hirens boot (in this case mini windows xp) You can also do without hirens, with normal windows. Once you are in the computer start, you have to find the management tools and finally the disk management. Following these steps we will know our computer partitions: there are two partitions but one is unallocated, it is not in use. The other is a 29.27 GB one, with NTFS file system and in which there are only 2.04 GB free.

2)Linux

Now we have done the same with another tool of hirens boot cd: linux. Obviously we obtain the same information that with windows because it is the same computer. There are only one active partition called /dev/sda1 of 29.27 GiB.

3) Dos Programs

This information is obtained from Dos programs. The first partition does not have any memory. The second one of 127 KB is primary partition but unused. Finally, the third one is also primary and it is of 7,630,720 KB. This last partition fills 1.022 cylinders, 35 heads and 9 sectors.

 

64-BITS COMPUTER

We also analyze a 64 bits computer at home. Here we will saw you its different hard disk partitions from different ways.

1) Windows 

With windows, without booting the computer, we obtain this information.

64 bits
There are two partitions, but one of them is recovery, that is a partition that contains all the settings of your computer to leave it exactly as it comes from the factory if you want to format it. It has a sice of 11.93 GB with a NTFS file system. The other partition is a primary partition of 286.16 GB of which 109.93 GB are free.

But if we boot the computer with hirens boot and the option mini windows xp we get the same information:

2) Linux

To see the partitions of a hard disk in a Linux computer you have to use ubuntu or your hiren’s boot cd. Then you have to search the gparted  in the menu or applications and select accesories. Following these steps you will arrive to the partitions of your computer:

gpartedbuena
Here we can see that in this computer, the hard disk has two avaiable partitions of different sizes. There first one is of 286.16 GiB, but there are only in use 175.14 GiB. The other one is the recovery and it is a 11.93 GiB one, in which there are used 10.03 GiB. The other small partition is not avaiable.

 

3) Dos programs

We can also get this information through the hiren’s boot cd using the option of “Dos programs”. As we have said before check if you are looking in the right hard disk, if it’s wrong press F5 to change it.

The computer has a hard disk of 305,245 Mbytes numbered in 38,913 cylinders, 255 heads and 63 sectors. This memory is divided in 5 partitions. As you can see, the first one is the master boot record and it is only used for booting the operating system. The second one which is unused is of 1,023 KB; the third one is a NTFS and stores 300,057,000 KB; the fourth one is also a NTFS and keeps 12,509,184 KB; finally, the last one that is not used keeps 3,416 of memory. The first four partitions are primary.

This information is from other computer with x64 structure that has a hard disk of 476,940Mb and has 2 partitions but the first one is not used while the second partition stores 488,386,583 KB and it is a primary partition.

RASPBERRY PI COMPUTER

We have been looking in other types of computers with an arquitecture, that is ARM (Raspberry Pi).

To get the information from this PC you have to open terminal, type ‘gparted’ and press Enter. It will open, you have to check if it is the right disk because maybe you are looking your USB.

This computer has a first partition of 63.00 MiB only used forma booting, a second partition that is a extended one of 7.36 GiB where 5.70 are in used and 1.66 GiB are free. The last partition of 55.00 Mib has not a particular purpose, it is not defined.

To make a screenshot in a raspberry computer you have to type in the terminal:              scrot -c -d10 or the number of seconds that you want to take the image.

CONCLUSION

The conclusion that we can get of this practical is that each computer has a different hard disk, but the hard disk does not depend in the operating system because we can see that in the same computer, with linux, windows, or dos programs, we obtain the same partitions with the same información.
