how to restore formatted hard disk

platter has two sides, the number of the face from the fit side of the disc start, facing up on the side of the label is 0, the downward side of the label is 1. The 2nd disc faces up with a label of 2, faces down to 3, and so on. The hard disk has an electromagnetic read and write head on each side of each platter. 1, magnetic surface (Side) The magnetic surface of a

The primary boot sector of a hard disk is a sensitive area. Its security directly determines whether the hard disk can be used normally. In-depth understanding and flexible use of the primary Boot Sector of the hard disk will help

After successfully creating a virtual

, it will automatically hide the Bad Sectors of your hard disk and partition them. However, you can pick up four blocks and use them to ask if you agree. You can choose "Y ", it is equivalent to fdisk once, but it must be formatted after the computer is restarted. (Note: when there are many bad sectors on the hard

don't have to worry about it. The data is still stored on the hard disk, after the drive C is formatted, unformat in nu8.0 can be restored. If you have used the mirror in the doscommand or the image program in nu8.0 to create an image file for the hard disk, the

used, use the Swapon command to specify the swap file to be enabled;(6) You can use Swapon-s to check the usage of swap;Example 1 is as follows:(1) Use partition as swap·Fdisk/dev/hda· Input N; create a new partition. If the previous example is used, the hard disk should have space left. Here, create a m partition;· Input t; then input 7 (the new partition here is hda7, which can be viewed by P); input 82

/HDA6 Data sets the volume label of this partition as data;Note: In here do not modify the HDA1~HDA5 volume label, may cause the inability to boot, and then do the instructions.Vii. Introduction Mount instruction Mount partition1, the concept of mount: When you want to use a device, for example, to read a formatted partition on the hard disk, CD-ROM or software a

partition. It has a very convenient graphic interface tool in Windows NT/2000/XP, the location is slightly different in different Windows versions (for example, control panel, management tools, computer management, and disk management in 2000 ). In Linux, fdisk can be used for partitioning, or a graphic interface program with the same functions. Each primary partition and logical partition are stored with additional information that identifies the fi

partitioned and formatted. We can boot the system through bootable discs, such as the win98/me boot CD, or floppy disks with bootable features. If your system does not yet support this startup mode, go to the BIOS setup program and modify the first boot Device to either the ATAPI CD-ROM Drive (CD drive boot) or floppy Devices (floppy boot). Use the Fdisk command to partition with CD or floppy boot system, into a DOS state, run the "Fdisk" command, t

disk is actually a VHD file, which is merged into the VHD file regardless of how many files the user stores to the virtual hard disk). )。 The virtual disk format is divided into dynamic extensions (the size of the VHD file automatically expands as the file is stored inside) "Fixed size" (limiting the size of the stora

operation is performed on this hard disk" Type: M "list fdisk help" Here we want to add a new partition, which will be scaled out into a new partition, so that it can be identified by the operating system mounting. Type: N "command n to add a new partition" At this time, fdisk will let you choose to add as a logical partition (number starting from 5) or primary partition (Number 1 to 4 ). Select the primar

" under the main menu, in the dialog box that appears, select the storage location of the recovered file. In this case, you can restore the deleted file by mistake in Win9x/Me. 2. Solutions in WinNT/2000 In other words, how to restore a deleted file in the NTFS partition. For this relatively simple requirement, File Scavenger (http://www.quetek.com/) is fully qualified. Of course, File Scavenger is very targeted-it can only be used in WinNT/2000 systems (at the same time, it must log on to the s
