Operations that could very easily bring about logic failure:
01 --- Delete partition
02 --- format drive
03 --- Delete files or folders
04 --- Infected with virus
05 --- Unable to finish partition operation to get a lengthy time prior to reinstalling the operating system
06 --- When accessing the drive, the dialog box of 'Unformatted Drive' pops up
07 --- When employing GHOST causes data loss
08 --- When performing a CHKDSK scan will change the damaged file or folder extension to a .CHK file
09 --- When making use of recovery CD to lead to information corruption
10 --- When low-level formatting
It really is encouraged that customers really should shut down as soon as you possibly can right after a disaster to prevent other individuals from writing information for the region where information is lost devoid of knowing it, causing secondary damage and irrecoverable data. In addition, a lot of customers blindly listen for the misleading of some non-professional personnel when the above circumstance happens. Set up several recovery application or other operations around the failed disk. These are quite hazardous, and they may form many coverage of your original information and result in information. Unable to restore.
Format error
Typically brought on by man. Probably the most dangerous thing is: the original technique installed winxp or win2000, typically the technique disk is C drive, the file technique is NTFS format, along with the other partitions are FAT32 format. When the user wants to reinstall the technique, use the win98 boot disk to begin, run the FormatC: command, the format is actually not the C drive, for the reason that the original C drive is in NTFS format, the NTFS partition cannot be noticed beneath DOS, and DOS automatically puts the hard disk on the initially FAT32 partition is regarded as the C area, and this partition occurs to become the partition where the user stores data, formatted within the incorrect spot. Format the partition devoid of writing data for the formatted partition, the data might be recovered 100%. Note: Do not write information for the formatted partition any longer! Only within this way can we guarantee that it is going to not result in secondary damage to the data.
Miscloning (Ghost)
This predicament is much more typical, the cloning order is reversed, the cloning alternative is chosen wrong (for instance, the original partition ought to be partition to partition as well as the wrong partition is selected to the hard disk, and so on.). Note: Do not create data to the hard disk that was cloned by error! Only in this way can we assure that it can not trigger secondary harm towards the data.
Partition logic error
Typically the size with the partition is distinct from the actual size. For example, a 10GB partition is displayed as 120GB within the computer, or a 120GB partition is displayed as 10GB. Similarly, the size in the challenging disk itself often has such difficulties, from 60GB to 0GB. In
https://beautyrub64.livejournal.com/1550.html , the really hard disk information might be recovered 100%. Note: Don't reformat the abnormal partition or difficult disk. Only in this way can we guarantee that it is going to not result in secondary damage to the information.
Partition table is missing
That is also a very prevalent computer software failure. The functionality is as follows: All the original partitions or some partitions of the tough disk are gone. It is possible to see the unpartitioned tough disk or unpartitioned space inside the disk manager (winxpwin2000win2003). Note: Do not repartition and format the really hard disk. Only in this way can we ensure that it is going to not trigger secondary damage for the information.
Disk prompt to format
Adjust to RAW format, the volume label of the disk is gone, and it becomes 'local disk'. Double-click the drive letter to enter, and it prompts 'The disk is just not formatted, do you desire to format it now?', Right-click to view the E disk properties and display the file system In RAW format, the capacity becomes 0 bytes. Matters needing consideration: 1. Usually do not format; 2. Usually do not create information to the failed partition, so as to make sure that it will not cause secondary harm to the data.
PQ conversion error
During the procedure of FAT32-NTFS conversion or re-adjusting the partition size, a plan error or possibly a sudden power failure will result in the hard disk partition to be inaccessible, prompting details such as disk parameter errors. An additional situation is the fact that the conversion from FAT32 to NTFS is completed successfully, however the Chinese-named files and file additions come to be ???? or grow to be garbled. Matters needing attention: 1. Don't format the abnormal partition; 2. Usually do not write information for the faulty partition, so as to ensure that it's going to not lead to secondary damage towards the information.
Difficult disk logical lock
The performance is that regardless of which machine you hang this hard drive, the program won't perform, but the bios can detect that the challenging drive is good. Note: There is absolutely no ought to spend focus, for the reason that there is absolutely no strategy to perform any operation on the hard disk, except from this machine to that machine (that is typically uncomplicated to trigger hardware failure).
BOOT sector error
This is by far the most widespread challenging disk software program failure, typically manifested as: 1. The partition might be opened, and files and directories turn into garbled; 2. The partition cannot be opened. Clicking around the partition will prompt the user to say 'This partition will not be formatted. Do you need to Format initially. ' The causes of such failures are generally: abnormal shutdown, virus damage, sudden energy failure, and so forth. In the event the above symptoms are brought on by a single BOOT sector issue, the data within the challenging disk partition can be recovered. Matters needing focus: 1. Don't format the abnormal partition; 2. Do not create data to the faulty partition to make sure that it can not bring about secondary damage for the information.
Really hard disk logical bad sectors
Also known as soft and poor sectors, typically caused by improper operation or use of software program.

1. When you open, run or copy a file, the operation speed with the challenging disk slows down, and it may be unsuccessful to get a extended time, or it may show a long-term death 'biting' a particular region or the abnormal sound in the challenging disk reading. Or simply the Windows method prompts 'Unable to read or write to this file', these can indicate that a bad element of your really hard disk has appeared;
2. The Scandisk disk program runs automatically every single time you turn it on, which definitely indicates that there are actually essential errors in your difficult disk that must be repaired, such as poor sectors. If you cannot pass it smoothly when running the system, it indicates that the tough disk need to have poor sectors. Naturally, though the scan may also pass, the red 'B' mark seems, indicating that in addition, it has poor sectors;
3. The tough disk cannot be booted when the computer is started. Right after starting with a floppy disk or CD-ROM, it is possible to see the difficult disk drive letter, but you can not operate the location or the operation is wrong or you can't see the drive letter, which indicates that poor sectors might seem around the difficult disk. Specific functionality for example the 'Harddiskdrivefailure', 'Harddrivecontrollerfailure' or similar facts throughout the power-on self-test, could be judged as a hard drive or really hard disk controller hardware failure; when reading and writing the difficult disk, it prompts 'Sectornotfound' or 'GeneralerrorinreadingdriveC' , It indicates that the tough disk track has physical harm.
Of course, this situation may well also be brought on by physical bad sectors, please refer to (hard disk physical bad sectors)
Matters needing consideration: 1. Usually do not run the terrible track repair system (unless you don't want information); two. Usually do not run the Scandisk command. Only in this way can we ensure that it will not lead to secondary harm to the data.
Accidental deletion
Similar to the case of mis-partitioning and formatting, so long as you don't write information to the mis-operated partition, the recovery probability is above 95%. Accidental deletion recovery, accidental deletion information recovery, accidental reduce recovery, accidental cut information recovery. Note: Do not write data for the partition that was deleted by error! Only in this way can we assure that it can not trigger secondary harm to the information.
Use restore disc
The operating technique is just not normal, and working with the recovery disc to restore normally causes the original partition to be lost. Note: Do not write data for the hard disk any longer! Only in this way can we make certain that it's going to not lead to secondary harm for the information.
Virus infection
Virus damage, Trojan harm: I don't know I was infected using the virus, I discovered abnormal phenomena through use, as well as the partition table (PartitionTable) or some other element was damaged in the moment of browsing and remedy. Like the CIH virus (Virus), the difficult disk can't be read in the moment of infection. Note: Don't write data for the challenging disk any longer! Only within this way can we ensure that it can not cause secondary harm towards the information.
