Hello admin! Got me new laptop with a UEFI BIOS, the owner complained that the laptop was very slow and freezing, and asked me to roll it back to factory settings. But nothing worked for me with the rollback, despite several attempts, the rollback process froze in the middle and I had to emergency reboot. Then I tried to simply reinstall the operating system, but I failed here too, at the very beginning of the process Windows installations 8.1 appears blue screen with an error INACCESSIBLE BOOT DEVICE 0x0000007B or other NTFS FILE SYSTEM. I decided to check the laptop’s hard drive with the Victoria program, but how to do this, because in order to boot a new laptop from a bootable flash drive with the Victoria program, you need to disable the AHCI option in the BIOS and enable IDE, but this laptop does not have the IDE option, but only AHCI?
In short, I couldn’t boot from the flash drive and I downloaded a couple of Live CDs with this program online, but I can’t boot the laptop from them either, I also get an error.
In principle, you can remove the hard drive from the laptop and connect it to to a simple computer, but it is not advisable to disassemble the laptop, because it is under warranty.
Hello friends! For such an occasion, we have prepared a special bootable USB flash drive Live CD AOMEI PE Builder 32-bit with hard drive diagnostic programs: Victoria, HDDScan, CrystalDiskInfo 6.7.4, DiskMark, HDTune and DMDE. Using this flash drive, you can diagnose any hard drive of a laptop or regular computer.
We will diagnose a laptop that a friend of mine was going to buy at a fabulous discount in a new online store. I was immediately alarmed by the fact that the online store existed for only two days. The seller claimed that the laptop was completely new and gave us one day to diagnose it. I refused the whole day and asked for a quick diagnosis of the laptop directly from the seller.The diagnostic result made us doubt the seller's sincerity.Details later in the article!
First of all, download Live CD AOMEI PE Builder 32-bit. Do not pay attention to 32-bit, from this flash drive you can boot any computer or laptop, and it doesn’t matter which one is installed on it operating system: 32-bit or 64-bit.
In the main window of the WinSetupFromUSB program, select the name of our flash drive.
Put a tick on the item Auto format it with FBinst and check the box for NTFS or FAT32, it doesn’t matter.
Check the box Vista/7/8/Server 2008/2012 based ISO and click on the button that opens the Explorer window.
Explorer opens, find it on the computer ISO image Live CD AOMEI PE Builder 32-bit and select it with the left mouse, click “Open”.
The creation of a bootable USB flash drive Live CD AOMEI PE Builder 32-bit begins.
The bootable USB flash drive is ready.
We connect our bootable USB flash drive to the laptop and reboot.
If you do not have a completely new laptop without a UEFI BIOS, then we immediately boot from the flash drive.
If you have a new laptop with a UEFI BIOS, then first enter the BIOS and, this is very easy to do.
We save the changes we made in the BIOS and reboot, enter boot menu laptop and select our flash drive from it to load.
Press “Enter” on the keyboard.
Select AOMEI PE Builder 32-bit from the Live CD menu and press “Enter”.
Click "OK"
Loading desktopLive CD AOMEI PE Builder 32-bit.
Go to the folder Integrated Tools.
The folder contains six of the most famous programs for diagnosing hard drives.
1. CrystalDiskInfo 6.7.4
2.DiskMark
6.Victoria
These programs are more than enough to accurately determine the technical condition of your HDD.
CrystalDiskInfo 6.7.4
Very simple program with support for the Russian language, it will show you in a clear and understandable form SMART hard laptop disk and other information, for example: temperature, current and supported hard drive transfer modes (SATA 3 Gb/s or SATA 6 Gb/s), with spindle rotation speed of the hard drive, h The number of times the hard drive is turned on and the total operating time, as well as other information: firmware, serial number etc.
Based on the results of diagnosing the HDD of this laptop, we can say that it worked for about two months (396 hours), although the seller claims that the laptop is completely new. The seller also said that the hard drive on this laptop has a spindle speed of 7200 rpm, but in fact it turned out 5400 rpm, that is, slower.
Victoria
Program Victoria is the best (in my opinion) hard drive diagnostic utility, which is used by professionals and regular users . With Victoria's help, you can find out the SMART (self-test result) of the hard drive, as well as the condition of the drive's surface.
On the start tab Standard, in the right part of the window, select the hard drive you need with your left mouse and immediately in the left part of the window the passport data of our hard drive will be displayed, then go to the tab SMART.
Click on the button SMART and all hard drive self-test indicators will open, if you want to understand these indicators, then read ours.
Go to the button Test. On the right side of the program window, check the box Ignore And Read andpress the button Start, a simple hard drive surface test will run without error correction. This test will not have negative or positive effects on the hard drive, but at the end of the test you will know what condition your hard drive is in.
This test will show how much is on your HDD sectors with good read latency of no more than 5 ms, 20 ms, 50 ms and not very good sectors with read latency 200 ms and 600 ms, the number of sectors in which information could not be read at all (bad blocks) will also be shown.
I want to say that this test of the hard drive surface can be run in a running Windows, but the test will not be ideal, because in a running system information is constantly being written to the hard drive and because of this, the test results will not give a real picture.
The HDD test result is clearly not excellent, but most likely satisfactory, as there are quite a lot of sectors with a delay of more than 200 ms, and two sectors were read in 600 ms
Read our section with detailed articles about the program .
DiskMark
CrystalDiskMark is the most famous utility that measures the speed of your hard drive, select only the desired drive letter (in our case C:) and press AII, the hard drive performance test will begin, shows the average speed of sequential reading and writing to the hard disk by various data blocks, in a few minutes we will get the result.
1. Test of sequential reading and writing of large blocks of data;
2. Test of random reading and writing in 512 KB blocks;
3. Test of random reading and writing in 4 KB blocks;
I want to say that we have a slow hard drive, a test of sequential reading and writing large blocks of data on a hard drive of the most modern interface (SATA 6 Gb/s) should be at least 120 MB/s, in our case the read speed is 99.49 MB/s and records 94.49 MB/s, that is, everything will obviously not fly on this laptop, it won’t even help powerful processor and a large amount of RAM. In the end you will have to.
HDDScan
This program in its capabilities it resembles Victoria, but of course it does not live up to it, despite this, many users like it.
Left-click on the hard drive icon in the middle of the program window and a menu will open in which you can select the diagnostic tool you need. Let's see for example SMART hard drive.
You can also choose to test the drive surface.
HDTune
HD Tune is the most famous program for working with hard drive, capable of showing the speed of the HDD, scanning for bad sectors (bad blocks), showing the health status of S.M.A.R.T.
Tab Info shows all supporting drive functions.
The lower part of the window displays the firmware version, serial number, etc.
To tab Benchmark You can measure the speed of your hard drive.
Tab Health- will show health status S.M.A.R.T.
On the Error Scan tab, you can scan your hard drive for the presence of bad sectors in a visual graphical representation. All green sectors are good sectors, if there are red ones, then such sectors are bad blocks.
DMDE
Very good program to search and recover deleted partitions and simply deleted files on your hard drive.
It is not possible to describe working with this program in a nutshell, so I suggest you read our detailed articles about.
How else can you use a Live CD?
Friends, this Live CD AOMEI PE Builder 32-bit is built on the basis of the Windows 8.1 Enterprise operating system and contains a lot more useful programs, For example.
Live CD is an operating system that can be booted from any type of media. Such a system is not installed on a hard drive. Most often, such disks are used to resuscitate a computer when the installed operating system refuses to boot.
It is important to consider that live SD can contain any operating system. Most often users use OS Windows family. To boot from a “live disk”, you need to restart the computer and install the system media.
Advantages
Live CD has a number of advantages over a conventional operating system. First of all, it should be noted that it is possible to boot on absolutely any computer, even if the installed OS is damaged. This makes it possible to copy or move important documents to a safe place.
A tool such as LiveCD allows you to revive an installed operating system. This importance comes from having built-in tools. For example, Acronis and similar programs. The only thing to keep in mind is that some tools require a learning curve and should not be used by inexperienced users.
Most life SD can be fully loaded into RAM. This increases the speed of the operating system and installed programs. For the operating system to load into RAM, its size must be small. In this case, the amount of RAM should be several times larger than the size of the Live CD. That's why on weak computers better load the operating room Windows system XP or 7.
Another advantage of LiveCD is the ability to work on a computer that does not have hard drive or a small hard drive. It should also be noted that with the help of one Liv disk you can boot on any machine without fear that the installed OS will be damaged. In addition, life SD automatically detects everything after loading installed devices, such as printers, modems, etc.
Ease of use can be considered another plus. The disc must be downloaded from the Internet and then burned to CD. After this, you can reboot the machine and boot from the LiveCD. It should be noted that the navigation of most “live disks” is Russian, so there will be no difficulties in managing it.
Flaws
Unfortunately, LiveCD has not only advantages, but also disadvantages. The main disadvantage is the storage of operating system settings and data written to disk. To save changes and settings you have to use additional media. For example, a USB drive.
Another serious drawback is the rapid wear of CDs or DVDs. Even with careful storage and use, scratches and cracks will sooner or later appear on the surface of the disc. If damaged, booting from the “live disk” will not work.
Many users consider LiveCD loading speed to be a disadvantage. This is due to the fact that the operating system written to the disk is loaded into RAM and also configures the configurations of the hardware used.
Burning an image to disk
Before booting from a live disk, users need to burn the image to a CD or DVD disc. It all depends on the size of the operating system. First, it is recommended to install a program that allows you to record images.
Despite the fact that there is a huge number free applications, it is recommended to consider Astroburn Lite. The utility can be downloaded for free from the website “http://www.astroburn.com/rus/home”. The advantage of this program is that it takes up virtually no disk space.
After starting the program, you need to go to the “Image” tab. When the tab opens, you must perform the following steps in sequence:
- Select LiveCD or LiveDVD image.
- Change the recording speed (it is best to choose the minimum speed).
- Select a device intended for recording discs.
- Press the button to record.
Once the disc has been burned and checked for errors, it is recommended to restart the computer and boot from the “live disc”.
Recording a "live disc" to a USB drive
Sometimes users encounter such a problem as the absence of a DVD-ROM in their computer. This means that on normal LiveCD It won't be possible to record. There's no need to be upset, because boot disk can be made from a USB drive.
To create a boot disk, you will need the WInSetupFromUSB program. It is best to download the program from the official website located at “http://www.winsetupfromusb.com/downloads/”.
After installing and launching the application, you must sequentially perform the following steps:
- Select a USB drive for recording a “live disc”.
- If you are creating a boot disk for the first time, you should check the box next to the “Auto format it with FBinst” field.
- Select the type of image to be written to the USB disk.
- Press the “GO” button to create the disc.
After this, a bootable USB flash drive will be created in a few minutes.
Loading a "live disk"
Before booting from the disk, you need to configure the BIOS. To do this, you need to enable the ability to boot from a disk or USB drive. This can be done by setting the appropriate changes. Each BIOS configures things differently. While booting from the disk, a window will appear in which you need to select the required action.
In a few minutes the operating system will load. It should be noted that externally it does not differ from the OS installed on the computer. The difference can only be in the system version. Users can boot from any existing Windows operating system.
It should be noted that the Live CD contains all the programs necessary for operation. After the system starts, you can enter the start menu, and then select the program of interest. All devices connected to the computer will be automatically detected by the system.
With Live Disk, users can work in the same way as on installed system. The only thing worth remembering is that all changes to settings and documents will have to be saved to an additional storage medium.
Conclusion
Booting from a live disk solves many problems. First of all, such systems are used to restore the functionality of a computer. It is enough to use the tools downloaded to the disk, and the operating system will be restored. In addition, thanks to live SD, you can explore the capabilities of any operating system.
It should be noted that there are a huge number of live CD and DVD builds. Therefore, you need to download the image according to your needs. It is worth noting that “live disks” can contain not only operating systems, but also specialized programs such as Acronis.
