Description

Selector device of a hard disk of a Computer with several hard drives.

The present invention relates to a device  selector of a hard disk of a computer with several discs hard.

Background of the invention

Currently when several people use the same computer, can be produced in terms of security, various problems:

.

accidental deletion of files

.

improper use of non-proprietary information

.

pollution by computer viruses etc.

The installation of one or more hard drives for a theoretical separation of users, does not protect from problems mentioned above since, access is almost always possible and There is a possibility of virus contamination.

The most frequently used solution is the to physically change the hard drive accessed by the system computer by means of a removable (each user inserts his disk hard on the computer before initializing it), but this solution it also involves part of the problems indicated initially, as well such as the risk of physical damage of the removable hard drive itself, and It is uncomfortable for the user.

Description of the invention

The objective of the present invention is to solve the mentioned disadvantages, developing a device selector of a hard drive of a computer with several hard drives, that allows different users to use the same computer (not at the same time) without being able to access the information from one user to another, since the hard drives of the users that are not operating at that time are not accessible by the system and therefore cannot be contaminated with viruses computer and others.

According to this objective, the device selector of a hard drive of a computer with several hard drives, It is characterized by the fact that it comprises a means of selection that allow you to select the hard drive that belongs to one of the users and that user only access this disk Hard through an electronic circuit.

This fact allows to increase the comfort of the user to access your hard drive, reduce the risk of cause a failure, prevent the insertion of a hard drive that does not be yours, avoid accidental deletion of files, avoid improper use of non-proprietary information and avoid Computer virus contamination.

Advantageously, said device is characterized by the fact that said selection means are fed permanently through the power supply of the computer.

Additionally, said device is characterized by the fact that said selection means are push buttons that perform the function of the computer start / stop button.

The computer is started by operating the button corresponding to the hard disk or disk belonging to the same user, without having to press the button Start / stop the computer, since it is canceled.

Advantageously, said device is characterized due to the fact that said push buttons comprise an indicator LED of active user.

The LED indicates at all times which user is Connected to your hard drive.

Additionally, said device is characterized by the fact that said push buttons can be replaced by a rotary switch or similar.

Placing a rotary switch allows the button to start / stop being active.

Advantageously, said device is characterized due to the fact that the buttons can be complemented or replaced by a key for each user.

This allows to ensure confidentiality between users when necessary.

Brief description of the drawings

For greater understanding of how much has been exposed some drawings are accompanied in which, schematically and only to title of non-limiting examples, a case study is represented of realization.

In these drawings,

Figure 1 shows a scheme of how it is integrated  the device on the computer, and

Figure 2 shows a block diagram in the that shows the bottom of the circuit that feeds permanently through the power supply and the part top of the circuit that is fed through the connector of the source of hard drives.

Description of a preferred embodiment

Figure 1 shows a possible placement of the device in one of the compartments to put a CD ROM or a floppy drive of a computer. Assuming a specific application for 4 users, a panel with four push buttons 2 and its respective 3 LEDs or performance indicators. Said panel is connect to the electronic control circuit that is located directly behind. When one of the buttons 2 is pressed, They perform two functions:

.

The system

.

Only the disk or hard drives 5 belonging to that user

Said electronic circuit prevents them from activating at the same time two or more users, ignore subsequent presses performed on any button while initializing the system, or it stops when it has concluded the initialization

The buttons 2 of the invention replace physically and functionally to the start / stop button 4 of the computer, this one being canceled.

The invention can be installed externally, internally, as an expansion card or even incorporate it into the Computer motherboard during the manufacturing process.

There is no theoretical limit to the number of users, although for operational reasons it is recommended not to exceed six.

In cases where confidentiality is high, push buttons can be complemented or replaced by a key For each user.

The electronic circuit of the invention cannot Be influenced by computer programming.

The electronic circuit acts on the power of hard drives 5 although it could act at the same time or independently on the hard disk data bus 5.

Buttons 2 can be replaced by a rotary switch and thus take advantage of the button Start / stop 4 original.

The power of the electronic circuit is extracted from the power supply 6 of the computer, although It is also possible to do it using batteries or batteries.

Figure 2 shows in its lower part the part  of the electronic circuit that is fed permanently through of the power supply 6 consisting of buttons 2 for select the user, which put the entries high of flip-flop 7, but with the peculiarity that those levels only will pass to the exit, yes and only, if a single button is pressed, function exerted by logic circuit 8 in parallel with the outputs of the buttons 2, this one through an analog delay 9, activate the flip-flop clock input 7 and at the same time start the computer through a relay (on-board start button base).

The same figure 2 shows in its upper part, how once the computer is started, the top part of the diagram receives voltage through the power circuit 11 of the disks hard 5 of the source, allowing the second flip-flop 7 transfer the information from the first flip-flop 7 to the relays 10 that power hard drives 5, this second clock input flip-flop 7 receives the rising edge through another delay analog in order to ensure the non-influence of transients; to from here any press will not happen at the exit of the second flip-flop 7 since your clock input will always be at high level.
