and write the hard disk after the drive or the Drive boot system. You can use fdisk to reset the active partition for repair.
If a partition type is incorrect, the loss of a partition may occur. The fourth byte of the partition table is the partition type value. Normally, the basic DOS partition value larger than 32 MB is 06, and the extended DOS partition val
. If the program is damaged, it cannot be booted from the hard disk, but the hard disk can be read and written after being started from the soft drive or optical drive. The solution to this fault is relatively simple. It is most convenient to use the FDISK of the higher DOS version. When the FDISK with parameters/mbr i

Normally, the basic DOS partition value larger than 32 MB is 06, and the extended DOS partition value is 05. Many people use this type of value to encrypt a single partition and restore the
good news is that hard disk manufacturers are beginning to provide hard disks with built-in full disk encryption. The Momentus 5400 FDE.2 hard drive manufactured by Seagate is a leader in this field. Compared with ATA Hard Disk locks and software
The tendency of moving hard disks to be smaller and more bulky makes more and more sensitive data stored on them, so how to better protect the security of these data becomes a very urgent problem.
When Windows Vista was first launched, Microsoft said a very large security feature added to the operating system was BitLocker, a hard drive encryption designed to pr
In this article, I wowould like to cover a basic howto installing a second hard drive to explain and your storage needs.
It's been about a year since I purchased my new Linux system and I feel my 80 GB internal hard drive is running out of space already. so I 've decided to
the F drive. boot partition Very simple, the partition that holds the operating system file, for example you installed 2 system: Win7+linux then you are 2 boot partition. If you have windows, look at the Windows folder (system32 file) in that area, which is your boot partition, the default is C drive, you can also install F disk and so on. If you have
selected to start with the second hard disk). The result is that there is only one vertex and one cursor in the upper left corner of the screen, this method failed (only my computer has failed like this. If some netizens have succeeded like this, you can try it );
Then I checked the information on the Internet and asked a netizen, So I installed an EasyBCD in win7,
Then restart the computer and you will see NeoSmart

In addition to this method, you can also set a "mount point" when "Partitioning" (in fact, the function is equivalent to setting up a special place to store special things ")
There are many others. I will not elaborate on them one by one. The following figure

Step 2: confirm that the folder/USB has been created under the directory/mnt. If not, enter the command: Md/mnt/USBAfter the operation is successful, proceed to the next step.
Step 3: load the U disk with the following command:Mount-T vfat/dev/SDA/mnt/usb_diskAfter success, you can use the U disk, and the file is under the directory/mnt/USB.
Step 4: uninstall the USB flash driveAfter using the USB flash drive, you must first press the USB
Article title: Dual Hard Drive multi-system guidance for in-depth exploration. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
When Linux
in the specified position can not read the correct information and multiple positioning caused by. If the hard drive has an abnormal sound, you should turn off the power immediately. Do not blindly repeated power to try to avoid deformation of the magnetic head on the disk surface formation scratches, resulting in irreparable loss. In this case, the disk cavity must be opened in a clean room, and a good se
formatted hard drive. The software can recover a hard disk larger than 8.4GB and supports long file names. Damaged hard drives like missing boot records, BIOS parameter blocks, partition tables, FAT tables, boot areas, and so on can be recovered by it.
Software evaluation
The software scans the
Test hard drive Bad Sectors in CentOS
Hard Disk status testing tools: smartctl, Badblocks, hdparm
You can quickly see whether the hard disk is healthy by using smartctl. The command is as follows:
[Root @ qy ~] # Yum installsmartmontools-y
Start SMART
# Smartctl -- smart = on -- offlineauto = on -- saveauto = on/dev/sd
In the day when we surf the Internet, the computer hard disk has many important or non-public privacy or files, such as private photos or customer information, or anything! You can easily be hacked by hackers to steal your files, to solve this problem is to encrypt the file, I will tell you some easy to operate the small method:
The first method is useful for a typical user, such encryption.
Use the Group
disk, but it failed and the partition was successful. In the partition tool of Window7, right-click "computer"?> "Management") I use more than 200 GB. This is my score. First, format all. Then, use 40 GB of memory to format it into the FAT32 format (note that it cannot be NTFS format. Microsoft, you know .) In this case, the G disk can be used in Linux and Windows 7.
If you are afraid that the disk cannot be used due to a partition error, you can

RW = read indicates random reading, BS = 4 K indicates 4 K reading each time, and filename indicates the corresponding partition. Here I am/dev/sda6, direct = 1 indicates traversing the Linux Cache
We will test the sequential read, random read, sequential write, and random write speeds of SATA hard disks, SAS hard disks, and SSD
extensible firmware Interface). It is a new type of BIOS. In addition to supporting MBR partitions, this BIOS supports GPT partitioning.
Therefore, to use a 3TB hard drive must be a UEFI bios and GPT partition.
In the operating system, the 64-bit WIN7 and Vista,linux and Mac OS X1.6 support GPT booting, so you have to install 64-bit WIN7 or Vista, or
