Share a hard drive with everyone on your Wi-Fi network

Take advantage of your router's USB port with a little trick that lets you share a hard drive with anyone on your Wi-Fi network.

 

Cloud storage is expensive, but it's not the only way to share a bunch of files across many devices. Instead, you can use an external hard drive and your router to create networked storage accessible to anyone on your Wi-Fi network.

When it's set up, any files stored on that drive can be accessed by all devices on your network -- even phones and tablets. Here's how to set it up on Windows.

Step 1: Choose your drive

The drive you share can be as small as thumb drive, or as large as a 3TB external hard drive. Check your router's manual to find out if there are any storage limitations, since some routers have a storage cap.

Once you've chosen your drive, plug it in.

Step 2: Enable USB drive sharing

On any computer connected to your Wi-Fi network, launch a browser, and navigate to your router's IP address. You can find this on the back of the router, in the device manual, or by searching for it online. In most cases, it looks like 192.168.X.X.

When the page loads, you'll be asked to log in with your username and password. If you changed it, you should know it. If you didn't, it's probably still admin (username), and admin (password).
Those who fall into the latter category, please change your password as soon as you can, and before proceeding to the next step.

Every router's interface is different, but if yours has a USB port, you'll find a link entitled something like File Sharing under the Administrator settings. In this window, enable the file sharing server (also called SAMBA). Apply the settings, and exit.

 

Step 3: Access the drive

You're now ready to read and write to your attached hard drive. Open a file explorer window, and navigate to the Network folder in the left sidebar. Then, clear out the path at the top of the explorer window, and enter \\[your IP address]. So, for example, it might look like: \\192.168.1.1

With that, your drive will appear. Open it to access its contents, just like any other folder. If you're asked to log in, simply use your router's login credentials (the same one used to log into the Web interface.)
If you plan on leaving your hard drive attached, so that you can easily access it from any Explorer window. To do that, right-click the drive and select "Map network drive..." Give it a name, and the folder will appear in the sidebar.

To access the drive on other computers on the network, repeat step 3.

What is Dropbox and How Does it Work?

What is Dropbox and How Does it Work?

The latest storage destination for all your files is Dropbox. Not only does this feature allow you to store your data, it also allows you to share the same with others. Still wondering how is this sharing possible? Buzzle gives you the answer ...

Retrieve Deleted Files?
Dropbox will keep deleted files for 30 days before permanently deleting it. So, you will always have a month's time to restore those important, yet deleted files.

Dropbox is a one-stop destination for all your file needs. Though the Internet has been around for a while now, it was only after the advent of Cloud Storage that we could truly use the Internet to store data virtually. Drew Houston and Arash Ferdowsi are the brains behind the concept of Dropbox. The company is based in San Francisco and is funded by Sequoia Capital, Accel Partners, and Amidzad.

You can create an account on their website for free to get limited storage space (2 GB), or opt for a paid subscription if you wish to get more storage space (up to 100 GB). Let us get acquainted with this amazing way of storage and see how it works.

What is Dropbox?

Dropbox is an online storage facility that uses Cloud Storage to create backup facilities for all your files. You can share photos, docs, videos, and files using your Dropbox account. These files will be available on the computers, iPhones, iPads, and Android devices that have the Dropbox application, and are available on the Dropbox website as well. The concept of Dropbox is such that you can share files with others. The next time you create an important document, make sure you share it using Dropbox, so that you have a backup copy of the same. 256-bit AES encryption is used to secure the stored files. You can make changes to these files even after they are stored in Dropbox.

Technology Behind Dropbox

The software program (server and client) of Dropbox is written in Python. Python is a high-level programming language that allows users to write codes in a few lines as compared to other programming languages. On Windows, the py2exe utility is used for the source and application coding. On Linux, the bbfreeze utility is used for static linking the Python interpreter and the OpenSSL library.

Storing a File

When you store any file on Dropbox, here's what happens at the backend:

❶ You will drag-drop the file that you wish to store to the designated folder in your account, or copy-paste to the respective folder.

❷ Once the file is saved, it is synced to their online servers.

❸ These files are then encrypted and stored in Amazon's Simple Storage Service (S3) in different data centers across the United States. Amazon's S3 is a web service interface that provides storage for Internet users.

The network connection is peer-to-peer, but in case you want to share files with your friend, it is not mandatory that both of you be online. The Dropbox server will store the files with the relevant changes. These edited files will be automatically updated into individual folders.

Server Side Process

When you wish to upload a file which is 4 MB, here is what happens at the server side.

❶ Dropbox will check the size of the file. If it is <4 MB, it will continue with the process, but if it is >4 MB, the file needs to be broken into smaller units of 4MB. The reason being—Dropbox stores files in blocks of 4 MB.

❷ If the file fits into one block, the client side hashes the file. The hash function is an algorithm that will map data of variable length into a fixed length, which means the variable length file will be converted into a 256-byte string (in this case) and sent to the server.

❸ Once on the server, the cache will check if a file with the same hash function already exists. If the file exists, the cache will simply return its copy, but if the hash function doesn't exist, the file will be uploaded to a new location.

LAN Sync

In case of files accessed and shared on a local area network (LAN), the LAN sync technology is used. Here is how the sharing is performed:

❶ You have created a file and it is saved on your computer's Dropbox.

❷ When you make any change to the file, the syncing process is initiated.

❸ All the computers and shared folders that are linked to your computer will download this version of the file.

❹ However, with the LAN sync function enabled, the Dropbox will first check the LAN for any new file instead of checking for it on the central servers. Thus, the processing time reduces.

Getting Started

If you are new to the world of Dropbox, here's the process to get started with this 'feature' (as quoted by Steve Jobs).

To start using Dropbox, you will first need to download it on each device that you need to keep in sync with your account.
⇓
During the installation process, you will be prompted to enter a username and password. You have to create just one account, irrespective of the number of devices you want to keep in sync.
⇓
Once the installation process is completed, a Dropbox folder will be created on your hard drive.
⇓
You can drag-drop files in this folder, and they will automatically sync with other devices.
⇓
These files are now available on the website as well as on the shared devices' Dropbox folders.

The next time you think of buying a USB stick or hard drive to store your files, try Dropbox. You will be surprised to see how easy it is to share and access your files from mobile devices.
