Instructions

Save information on your hard drive. If this information is sensitive, remember that simply hiding a folder is often not enough. Archive such information in an archive with a multi-digit password to prevent accidental or malicious access.

Burn information onto CDs and DVDs. Computers tend to break down sometimes, and this can lead to the loss of all the information they contain. After recording to a disc, handle it carefully - store it in a special case or in a disc box.

Use removable media such as external hard drives and high-capacity flash drives. These devices support , meaning you can put a password on them that will prevent other people from accessing it. But it is advisable to install an additional security measure, similar to the case with storage on a computer.

Use online document storage services. Keep in mind that when using services such as Google Docs, you should archive all information and set a password before uploading files to the server. This method is considered the most reliable compared to storing files on physical media.

Video on the topic

Hard drives come in different purposes and capacities. Due to the increased need to store large amounts of information, disks have become necessary attributes of life. However, these storage media sometimes become unusable. To prevent this from happening, you need to treat them with care and precision and be able to store these devices correctly.

You will need

• -special box;
• -program for measuring hard drive temperature;
• - a computer with Internet access.

Instructions

Beware of dropped or impacted hard drives. The gyroscopic moment that occurs when a hard drive operates enhances the effect and effect of the impact, as a result of which the drive can completely stop working.

If the hard drive is an external device, pay attention to the conditions for turning off the drive and its subsequent placement. It is strictly prohibited by any hard drive manufacturer to turn the connector on or off while the computer is on, since current pulses can seriously damage the hard drive mechanics and electronics.

After disassembling the external drive box, do not touch the conductors and metal chips. The charge of static electricity, which can accumulate on the human body, pierces the thin semiconductor chips of the disk. To resolve this issue, first touch the drive housing.

The disc storage location should not be located near devices such as disposable lighters with a piezoelectric crystal. Such high-voltage devices create pulses with a voltage of 10-20 kilovolts, which is very harmful to the condition of hard drives.

When installing for storage, do not disassemble the disk; damage to the heads and platter surfaces may occur. In principle, disassembling the hard drive should be left to a specialist. Disc parts can be scratched very easily. This will not add durability and reliability to it, but the warranty service may well make claims.

Create an optimal temperature in the place where the discs are stored, and do not expose the discs to direct sunlight. Carefully wipe the air intakes of the ventilation holes with slightly damp cloths, clearing them of dust.

The Internet provides us with more and more new opportunities, making life easier. For example, new technologies make it possible to use the Internet to store important documents, including personal ones.

When traveling abroad, many are afraid of losing their documents and being stuck there until all the formalities are cleared up. If you lose your documents at home, there is nothing pleasant either. It's good that technology exists to get around this problem. As for abroad, it is still better to carry photocopies of documents certified by a notary with you. This way the originals will be safer.

However, if someone is afraid of a “total” loss of documents, then it is best to turn to the Internet, where there are universal services for storing any files, including personal documents. The names of these services: Dropbox, Google Drive, Yandex Disk. Cloud technologies allow you to access these services from any device.

All that remains is to scan the document and save it on any of the services, and after that you can view it from your computer, laptop, or smartphone. Moreover, this can be done from anywhere in the world where there is Internet. And it doesn’t matter if your computer or smartphone is broken - all information on such sites is reliably protected. Access the service from any Internet cafe or library and print documents if necessary.

It remains only to take into account a few nuances:

You will need to register on the site by creating a name and password to log in. It is better not to use your last name, first name and patronymic for this purpose; it is wiser to come up with something that is not related to you. And it’s better to have a separate email account.
- It seems that you need to scan and attach documents certified by a notary to such a service. Because no matter how securely your documents are stored, it is still not the original, but a copy. As a rule, copies are not valid without certification. These documents will also not have a real notary seal, but a scanned one. However, this is more reliable for communicating with bureaucrats.
- there is a possibility that your account will be hacked, and then the documents will become available to attackers. To avoid this, you need to come up with a strong password that is not used anywhere else. It should be long and consist of letters and numbers interspersed with each other. Dates of birth are the weakest passwords that can be deciphered very quickly.
- figure out where you will store the password so as not to forget or lose it, otherwise the whole idea of ​​​​storing documents may go to waste. In order to be able to recover your password, you need to record all the actions that were performed during registration on the service. Now even young people do not rely on their memory, not to mention the rest of the population. Also keep all records in a safe place.
