What is seagate backup plus ?

Hello there,

Seagate Backup plus is available as Desktop and Portable Hard drives. If you don’t know the difference between them, check out my previous post – Difference between External Desktop hard drive and External Portable hard drive.

Unlike other external devices, Seagate Portable plus is not just a storage medium, but it is a back up drive. So what makes Seagate Backup Plus distinct is its software which they call it as “Preloaded Seagate Dashboard”. Seagate Backup Plus comes with inbuilt software which aids the users to take backups from local as well as from internet. That means you can expect “Backup Plus Hard Drive” to take back ups from your desktop/laptop as well as from social networking sites such as Facebook and Flickr.

Hello there,

So, both are actually External and both appears as portable, so what could be the difference between  External Desktop hard drive and External Portable hard drive ?

The difference lies in the power and data transfers.

The External Desktop hard drive makes use of two cables – one for the data transfer ( USB cable ) and the other for power transfer ( POWER cable). The portable Hard drive makes use of ONLY ONE cable which acts as both power as well as data transmitters.

Though both are portables, the Desktop hard drive is actually an EXPANSION drive, while the other as its name implies – it is a portable hard drive.

“airmom-ng start wlan0” does not create mon0 for intel wifi link 1000 bgn – Solution

Operating System Back Track 5 R1
Trouble Airmon-ng not responding for Intel wifi link 1000 bgn card
Cause Older version of Aircrack

Aircrack-ng supports Intel wifi link 1000 bgn card. But the trouble is with the older versions of Aircrack-ng.

Back Track 5 R1 comes with pre-installed Aircrack-ng version 1.1-bt9 which actually doesn’t seems to support Intel Wifi 1000 bgn model cards.

With this older version of Aircrack installed, if you try to execute the command “airmon-ng start <interface>”, it doesn’t creates mon0 instead it just hangs. Refer the screenshot below.

airmon-ng not responding

The solution is to simply upgrading Aircrack-ng to the latest version. ( When this post is published , the latest version is 1.2-bt9 1.2-bt1 )

To upgrade perform the following commands ,

STEP 1:

First ensure that your trouble is with older version of aircrack. To check what version of aircrack is installed perform this command from the Terminal.

# dpkg -s aircrack-ng

If this displays the version as 1.1-bt9, then proceed further.

STEP 2:

Update the repository lists. You need to have internet enabled for this.

# apt-get update

Wait till all the lists are updated without any error.

STEP 3:

Now update the aircrack-ng to the latest version. The following command will update the Aircrack to the latest version.

# apt-get install aircrack-ng

STEP 4:

If your installation gets completed without any errors, you should be able to start the monitor. Execute the following command to check whether airmon-ng works.

# airmon-ng start <interface> 

Thats it.

Now you should be able to see it working, it would appear something like in the image below.
