Last week in doing the expansion of the log machine, found that yun-dimensional students will be a hard disk mount point is not consistent with the previous log machine, considering this will bring trouble to future maintenance, and then try to modify, at the same time, review the log machine before the Mount configuration, found that there is a chance to drop the pit at any time ... As for what pits, I wil
was hundreds of MB, and now a game is a few gigabytes. If you are partitioning on the basis of the averaging principle, the storage of these mega files will be in trouble when you want to save two of HDTV movies. Therefore, for a large amount of hard disk, it is very necessary to separate a capacity of more than 100GB partition for the storage of mega files.

Diskgenius is a very useful partition tool, however, in addition to the computer, hard disk partition, Diskgenius function There are many, for example, to help the hard drive to find the missing partition. So how did Diskgenius do it? Let's take a look at today's use of Diskgenius to find a way to lose space on the hard

The command is as follows:Tune2fs-J/dev/hda6After converting the hda6 partition to the ext3 file system, a message is displayed. In this way, data in the original partition will not be lost;6. view the current status of the file systemDumpe2fs-H/dev/hda6Display the hda6 partition information. This command has been described
I. Raid Definition
RAID (Redundant Array of independent disk independent redundant disk array) technology is the University of California, Berkeley, 1987
It was initially proposed to combine small and low-cost disks to replace large and expensive disks. At the same time, it was hoped that access to data would not be damaged when the disk fails.

, the last shutdown is not a normal shutdown, the system will check the data on the hard disk, so that time will be very long; in Ext3, which is the journal mechanism, The system checks the journal data at boot time to see if there is an error, so it is much faster; (5) Tune2fs–j/dev/hda6 convert ext2 to ext3 2, There are three journal modes in the Ext3: (
The easy way is to: on the U disk icon right click on the-> Property-> tool-> start checking-> check automatically fix file system error-> start, and soon the repair is complete. We can try, hehe. It seems to work the machine.
Some experience is: the general printing of the local virus is very much, so it is best to set the U

You can use DEBUG to read data from the zero-cylinder, zero-head, and one-sector disks on the hard disk as follows:

Hard disk is the important medium of storing information, when the hard disk fails, it is a very important work to find out the cause of failure quickly, and the failure analysis of the virus is as follows, for reference:
HDD controller failure (hard drive control failure)
As one of the core components in the computer, hard disk plays an irreplaceable role in the work. Especially now the integrity of large data age, hard disk storage of various data information, hard disk life is particularly import

What is S. m. a. r. t. SMART is a disk self-analysis and detection technology. as early as the end of 1990s, SMART was widely used when every hard disk (including IDE and SCSI) was running, several parameters of the hard disk are recorded, including the model, capacity, temp

User @ Ubuntu :~ $ Ls/dev/SD */Dev/SDA/dev/sda1
The results show that the hard disk and primary partition are found, but the extended partition is not recognized.
2. Install testdisk
User @ Ubuntu :~ $ Sudo apt-Get install testdisk

Operation Steps:
The computer's nominal hard disk capacity differs from the hard disk capacity shown by the operating system, for example: a nominal 40GB hard drive is less than 40GB in the operating system, which is not an error
or formatted hard drive. The software can recover a hard disk larger than 8.4GB. Supports long file names. Damaged hard drive like missing boot record, bios parameter data block, partition table; FAT table, which can be recovered by the boot area. This version uses the new data recovery engine and is able to
programs, thereby reducing user action steps. However, this feature also has a big problem: it will turn off the hard drive before the automatic reboot, and then turn on the hard drive power when the machine is restarted! As a result, the hard drive in less than 10 seconds of time interval, by the current two shocks, it is likely to occur a sudden "death" of the
