MBR in GPT without loss of data

What are MBR or GPT?

MBR = master boot record

GPT = GUID partition table

MBR and GPT are "partion tables" or on Romanian systems or partitioning schemes.

These are small partitions that contain data about disk partitions, partition type, file system used, and more.

What is the difference between MBR and GPT?

MBR is the old system that has been used since 1983 and has compatibility and all the older operating systems.

It also has a number of drawbacks, notably that it does not support larger 2TB (with 512 sector) and is not compatible with UEFI and advanced UEFI features.

GPT is the new partitioning system that provides support for "the future", ie for all the functions that exist and will appear in UEFI and in future operating systems.

What should a bluetooth speaker be so perfect?

There are some features that we want to bluetooth speakers when we want to buy one

It measures the battery's autonomy, just talking about portable stuff. Dust, water and shocks, to stay calm the beach, the pool or the rain (IP rating). Playback capabilities other than Bluetooth (jack jack aux, micro SD card slot) Price is another extremely important factor

Tronsmart Element Force review - a very exciting boxer

The Tronsmart bluetooth box ticks all the important features and functions, and that at a very good price (Chinese magic)

Windows Sandbox saves you from malware infections

Windows Sandbox saves you from malware infections

What is a Windows Sandbox?

Sandbox is a virtual machine integrated into Windows 10 version 1903, which acts as a virtual operating system that you can "dirty" with any malware or suspicious program.

How to install Windows Sandbox?

First you need to make sure you have hardware virtualization enabled in BIOS.

If the bios hardware virtualization is enabled, we switch to installation, or rather, activating the Sandbox.

Enabling Windows Sandbox is made by "Turning Windows features on or off".

What can you use for Windows Sandbox?

This new feature in Windows 10 helps us run various dubious programs without putting our main operating system at risk.

Another use for windows sandbox is running trial programs, so we do not "dirty" the host OS anymore.

Why does not Sandbox appear to me?

Only this version of Windows 10 / 1903 has been introduced.

Older Windows did not have [...]

Get cheap SSD purchase tips

SSDs cheaper, but it's a trick!

The price of SSDs has fallen sharply lately, thanks to the production that has grown a lot, and the chip capacity is getting bigger. - Get cheap SSD purchase tips

Not only does it store multiple bits on the same cell, but also multiplies the number of layers. Practically put the layers of cells on top of each other.

SSDs are like homes!

A good analogy would be living spaces. A NAND memory is like a living space, where people in a building are the data.

Imagine that the first single-layer NAND SLC memories were like a studio in a one-storey building, and NAND QLC memory is a suite of rooms in a building with 96 floors.

Resistance or rewrite cycles!

Each time you write and erase, the cell on the SSD is worn out. Older generations, [...]

A partition from multiple disks .... for what it is

Even if you have the impression that this tutorial will not be used immediately, it's a good idea to understand how dynamic volumes work in Windows. It's good to know how to make a partition from multiple drives.

You will also understand how some configurations are made on the servers, where the volume space needs to be very large.

Why merge multiple drives into one partition?

A few days ago I installed Bitcoin Core on Windows. While installing, I realized it would take a long time, because it has to download the blockchain.

This blockchain has some 240 GB and is steadily growing.

During the download of the hard drive that I chose to place the blockchain, it was a load of 100% and the writing speed was a few KB / s.

It took some 3-4 days ....

Install NVMe SSD on older motherboards

Why install a NVMe SSD on an older motherboard?

There are many reasons, but mainly a SSM NVMe has higher speeds than a SATA, and the price is similar.

An SSM NVMe can reach 3500 MB / s, while a solid state drive SATA does not exceed 550 MB / s.

Why not buy a new motherboard with NVMe support?

The main reason is that a new motherboard involves very high costs. Even if you say, find the cheap motherboard, you still have to spend money on the DDR4 RAM, that old one does not work anymore. You also need to change the processor, because that's how it works.

Performance gains, on the other hand, will not be so great, because in the last 6-7 years there have been no high performance leaps, but rather [...]

The role of a laptop is to be a portable computer, and when we say portable we automatically think about the battery. so it is extremely important to know how to check battery health.

Technology has evolved over the last few years, but it seems like the batteries have gone a bit slower; Despite the higher capacities of LIPO batteries, they have remained the same number of Charge Cycle Counts.
