How hard is to delete a file on your hard disk?
Jonathan Caceres, Oct 08, 02:02
Today an office worker has to deal with hundreds of files. But how hard is to
delete a file?
Most people could said in a tenageer way that this question is pretty obviously
to answer, just hit the delete key on your keyboard.
We can tell you that yes and no that answer is correct. The file you see on
your monitor or display is just a graphical representation of a physical
address on your hard disk.
That means the computer shows you a graphical simulation of an address location
on your hard disk, deleting the file from your monitor is what you can see but
in reality the file still sitting on your hard disk all the time.
But what really happens? the OS (operative system), renames the file that tells
this file is not longer visible for the system but still remaining on the physical
address on the hard disk.
But good news of bad news for some people, the file still there and can be recover
so that make so easy for law agencies to discover the undiscovered using
forensic tools to restore delete files, hidden files, or other form of hide
information deeply inside a files.
Delete a file could be harder than you think.
ToolsNorton Utilities Suite program WipeInfo
Overwrites over and over the hard disk location until is deleted any
source of information.

Lost your file in you USB device
Jonathan Caceres, Oct 08, 02:06
Problem: forgot to save or ejected properly
your USB external device memory or hard disk.
Trying to recover a file could be stressful task and critical when you whole work
depends on that. A backup file can not be found or your Ms Office suit
can not recover unsaved documents.
What I can do to recover my file from my USB memory stick or Hard disk?
This is what you can do
Use this command in your command prompt window. You know how to open that
1. Windows key and then the key r
2. type cmd
3. locate your usb drive letter normally E:, F:, G:, ..., Z:
4. you do this like cd\ enter then type cd E: and then enter
5. now you are here E:\ then
6. type attrip -r -a -s -h /s /d
something like that E:/attrip -r -a -s -h /s /d
7. then you probably can see again the file/s appear in the USB folder
Not enough free disk space UBUNTU Linux
Jonathan Caceres, Oct 08, 02:06
For several weeks my adorable PC has this pop up message every time the software updater were running.
Not enough free disk space
The upgrade needs a total of 126 M free space on disk '/boot'. Please free at least and
additional 33.3 M of disk space on '/boot'. You can remove old kernels using 'sudo apt autoremove',
and you could also set COMPRESS=xz in /etc/initramfs-tools/initramfs.conf to reduce
the size of your initramsfs."
However, it did not work with that suggestion so, the other way found it for that issue is the following;
First, I check which version is currently being used with this command. You might have
downloaded a new version but have not rebooted and are using the prior version. If you
need to reboot to activate the current version, do so before continuing.
_____uname -a
Example output:
Linux srv-ubuntu
4.4.0-112-generic #135-Ubuntu SMP Fri Jan 18 11:48:38 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
Next, I would list the kernels in /boot (mine all started with "vm" as a prefix
because I run in a virtual environment)
_____ls -l /boot/vm*
Example output:
_____-rw------- 1 root root 7104528 Jan 9 2018 /boot/vmlinuz-4.4.0-109-generic
_____-rw------- 1 root root 7110608 Jan 19 2018 /boot/vmlinuz-4.4.0-112-generic
Next, I would find the matching headers:
_____sudo apt-get purge linux-image-4.4.0-109-generic
_____ls -l /usr/src
Example output:
_____drwxr-xr-x 27 root root 4096 Jan 13 2018 linux-headers-4.4.0-109
_____drwxr-xr-x 7 root root 4096 Jan 13 2018 linux-headers-4.4.0-109-generic
_____drwxr-xr-x 27 root root 4096 Feb 2 2018 linux-headers-4.4.0-112
_____drwxr-xr-x 7 root root 4096 Feb 2 2018 linux-headers-4.4.0-112-generic
Then I would remove the matching headers with a command like this
(note, you do not need to include "-generic" at this point):
_____sudo apt-get purge linux-headers-4.4.0-109
