HARD DISK DATA RECOVERY

Disk Data recovery is a process of salvaging data that is lost due to
a physical or a logical damage of any storage media such as hard
disks, memory sticks, USB drives, flash drives, and external zip
drives.

Scenarios of data loss

Common scenarios of data loss involve hard disk failure, human error,
and accidental deletion of data, software malfunction, and virus
attacks. Literally, the lost files / data are not erased immediately
after deletion, instead, references to those files in the directory
structure are removed, and the memory space occupied by them is made
available for overwriting.

Measures to be taken to avoid data loss

Data recovery is possible even if the disk is formatted, re-formatted
/ re-partitioned. When the disk is formatted all windows attributes
are set to default values and data is still available on the hard
drive. So, recovery is possible even after formatting the hard drive.
If a file is deleted by using shift + Del key, it bypasses the recycle
bin. Unfortunately, in this case recovery is beyond Windows. But it's
not beyond the abilities of any third-party recovery utilities.

So avoid using the computer to prevent overwriting of data, because
chances of recovery will decrease considerably.

Data loss due to logical damage

If the data lost is due to logical damage then, in majority of the
cases, the original data can be recovered by specialized data recovery
software, where, the end user gets an intuitive interface which guides
him in every single step of recovery.

Data loss due to physical damage

If the loss of data is due to physical damage then we can go for data
recovery services. If the damage to the disk is due to bad sectors the
disk may be cloned or imaged and recovery can be carried further. Once
the disk image is taken and stored in a safe location, the file system
may be reconstructed and recovery can be done, from the reconstructed
file system.

Recovery of data

Windows doesn't provide any in-built recovery utility to recover
deleted / lost data. Fortunately, there are many recovery utilities
provided by third-parties, and one of them is the recovery software.

3 addons for Firefox That Will Double Your Internet Browsing Speed

There are many people out there complaining about the Firefox RAM
Memory Bug. Lets get it straight. It's not a bug. It's part of the
cache feature. This 'feature' is how the pages are cached in a tabbed
environment.

To improve performance when navigating (studies show that 39% of all
page navigations are renavigations to pages visited less than 10 pages
ago, usually using the back button), Firefox implements a Back-Forward
cache that retains the rendered document for the last five session
history entries for each tab.

This is a lot of data. If you have a lot of tabs, Firefox's RAM memory
usage can climb dramatically. It's a trade-off. What you get out of it
is faster performance as you navigate the web.

Now a lot of us have found the 'secrets' on how to manipulate settings
in "about:config" to drop the memory usage as long as possible and to
increase the speed at which Firefox loads sites. Read on to find out
how to do this.

Remember: Firefox www.firefox.com is the best internet browser
available (in my opinion), and these tweaks below will make it even
greater and faster. So enjoy!
Reduce the amount of RAM Firefox uses for it's cache feature

Here's how to do it:
1. Type "about:config" (no quotes) in the adress bar in the browser.
2. Find "browser.sessionhistory.max_total_viewer"
3. Set it's value to "0";(Zero)
Increase the Speed in Which Firefox loads pages

1. Type "about:config" into the address bar and hit Enter.
(Normally the browser will make one request to a web page at a time.
When you enable pipelining it will make several at once, which really
speeds up page loading.)

2. Alter the entries as follows:
Set "network.http.pipelining" to "true"
Set "network.http.proxy.pipelining" to "true"
Set "network.http.pipelining.maxrequests" to some number like 10.

This means it will make 10 requests at once.

3. Lastly, right-click anywhere and select New-> Integer. Name it
"nglayout.initialpaint.delay" and set its value to "0";.(Zero)

This value is the amount of time the browser waits before it acts on
information it receives. If you're using a broadband connection you'll
load pages faster now.
Optionally (for even faster web browsing) here are some more options
for your about:config (you might have to create some of these entries
by Right Click –> New– > Interger or String

network.dns.disableIPv6: set "false"
"content.notify.backoffcount": set "5"; (Five)
"plugin.expose_full_path": set "true".
"ui.submenuDelay": set "0; (zero)
Reduce RAM usage to 10mb when Firefox is minimized:

This little hack will drop Firefox's RAM usage down to 10 Mb when minimized:

1. Open Firefox and go to the Address Bar. Type in about:config and
then press Enter.
2. Right Click in the page and select New -> Boolean.
3. In the box that pops up enter "config.trim_on_minimize". Press Enter.
4. Now select True and then press Enter.
5. Restart Firefox.

These simple tweaks will make your web browsing with Mozilla Firefox
2-3 times faster and easier. And I think they are fairly easy to
apply. Enjoy!
