Free hard drive repair iso to common hard drive failures as following:

1. Power caused the hard disk does not start properly.
Computer power supply output voltages are +5 V and +12 V. The hard disk starts need +12 V voltage and 4A current, hard work of the current 1.1A. Boot floppy disk only about +10 V voltage and 1.3A current, while the operating current of 0.5A. Computer power supply’s output voltage is less than +12 V, then the hard disk will not be able to start and work. To deal with such failures, it is necessary to return to the +12 V power supply output voltage.

2. Motherboard battery shortage caused the hard disk can not start.
The rechargeable battery on the motherboard (usually a lithium battery) is used to Save parameters which include the clock, date, number of floppy disk drive, type, drive number, type, display mode, memory capacity, expansion of capacity and other system parameters. When boot the Power On Self Test, BIOS automatically detects the CMOS parameters table, if not match, then the crash occurred. Lithium battery voltage of +3 V ~ +6 V. If the battery voltage is less than +3 V or battery failure, the hard disk can not be identified.

3. Parameter error caused the hard disk drive can not be started.
The hard disk parameters include hard disk capacity size, head number, track number, sector number and so on. Different manufacturers hard disk, its parameter values vary. If the hard disk parameter values are set incorrectly, then the hard disk can not be activated. At this time the hard drive heads need to re-set the number, track number, sector number equivalent. Method is: First, after the boot to be self starting, press the DEL key to enter CMOS SETUP to set the state. Then, the parameters set COMS: Select STANDARD CMOS SETUP section of the TYPE item TYPE fill in the correct values. The board generally has a hard drive self-test function. Enter the CMOS SETUP Settings menu, select “IDE HDD AUTO DETECTION” ok.

4. The the hard disk 0 track destroyed caused failures.
DOS operating system on the hard disk 0 track, if the hard disk 0 track is physical damaged, the hard disk will not work. Generally the repair method is: First, as far as possible backup the hard disk data and useful documents, if the hard disk 0 track damaged, the hard drive data, files can no longer as normal methods to back up, BIOS interrupts need to use a backup method according to each sector; and then format the entire hard disk, and then re-FDISK the hard drive partition, and finally logical FORMAT the hard disk, and install DOS operating system and related documents. If the above method is invalid, then first starts with the KV300 anti-virus, and then A: system disk to start, run SCANDISK scanning C disk, if it occurs in the first cluster with a red “B”, shows that the zero track damage. Then use DE on PCTOOLS 9.0 (the software can see the starting point of all partitions on your hard disk), run PCT90 directory DE. EXE, reports are now run in read-only mode, the election Op-tions Menu → Configuration, remove the Read Only by a space in front of √, save, then exit. Select the main menu Select → Drive; entered after the Drive type → Physical, according to spaces selected, and then TTab button to switch to Druves items, select the harddisk, and then select OK Enter. Then return to the main menu, open the Select menu will appear Partiton Table, select the drive that followed the partition table information. The partition is started from the hard disk 0 cylinder, then change the partition of the Beginning Cylinder 0 to 1, save and exit. Restart, press Delete key to enter the CMOS settings, to “IDE HDD AUTO DETECTIOND (also see the number of CYLS fewer)”, save, then exit at this time and then re-partition the hard drive, formatting, install the appropriate software.

External Hard Drive Repair Diagnostics

manyu — Tue, 19 Jan 2010 02:16:30 +0000

Hard drive has a problem, in need of repair, first of all what have to do is the hard disk diagnostic. Hard disk has bad track In addition to the quality of the hard disk itself, as well as the aging, usually not be able to treat the hard disk, such as too little memory caused application software frequently visit hard drive, too frequently defragmented, frequent partitions, formatting, improper over clocking, Power quality is not good, the temperature is too high, undesirable dust and vibration. Bad Track is divided into two kinds of logical bad sectors and physical bad sectors, the former for soft bad sectors, usually caused by improper operation or use of the software,
Software repair; the latter is a real physical bad sectors, it shows that the hard disk track generate a physical injury, only by changing the hard disk partition, the use of sector or to hide to resolve.

Here are hard drive diagnostic essentials.

1. Check whether the department have power supply
2. Connection (Cable) is connected correctly or not.
3. Check the settings. Disk Select Jumper(Master/Slave)。

4. Check the installation (set up) is correct or not.
5. Check spidle motor is rotating or not.

6. Check whether the head in the initialization process normally
Drive failures are divided into the following categories:

- PCB Fault
- Motor / Bearing Fault
- Kai / stop system failures
- Read / write head failure
- Failure and surface scratches head
- Bad Sector
- Part or all of the firmware data loss.

How to Repair Hard Drive

When we determine the hard disk has bad sectors, we can not determine it caused by logical bad sectors or physical injury in the end. We can only follow the steps from simple to complex to repair, the general logical bad sectors can be solved through a simple software fix, however, some physical bad sectors will need further repairs to ensure the hard disk data security and normal use. How to repair hard drive? Here is a detailed method.

1. Logical bad sectors Repair.

Under normal circumstances, a number of legitimate software will write some information on certain sectors of your hard disk, other software can not access this sector, in which case, the hard disk detection tools will also be mistaken for the sector had bad sectors, the general This situation without the need for repair,

There is another situation that is caused by improper use, for example, when the hard disk read data, in the accident it restart, there may have logical bad sectors, in serious cases can even produce physical bad sectors. At this point we can use the Windows own disk tools to scan the hard disk and automatically fix the error.

Specific steps are as follows (in Windows XP for example), in my computer select the drive letter and click the right mouse button, the pop-up drive in the Properties window, select “Tools → Check Now” and select “Automatically fix file system errors” and the “Scan for and recovery of bad sectors” and then click Start.

This method does not fundamentally solve the problem. More appropriate way is backup the hard drive data, and then re-format the hard disk partition, in general, if the hard disk failure is just the logical bad sectors, we can completely solve the problem. Of course, it is recommended, after carrying out re-partition and format, using DOS hard drive under the Scandisk again tested to ensure that the logical bad sectors hard drives are fully restored.

2. Repair physical bad sectors

If you follow the steps above to re-partition formatted, still find the hard disk has bad sectors, it is likely that a physical hard disk has bad sectors. In fact, in this case, Another software can be used for low-drive cells, carrying out re-format the partition, and some hard disk damage may also be resolved in this way.

(1). Low-level format the hard drive

There are two ways, one is through the tool which motherboard BIOS comes with, another is through software to low-level format.

(2). Shield Physical bad sectors

We hide the bad sectors into an unused partition, you can use the software, PQ Magic, this software has a DOS and Windows version, but we are usually discovered the hard disk still has a bad area after formatting, but this time did not install the Windows system, so recommended the use of DOS version of the PQ Magic.

If you can’t repair hard drive by yourself, the hard disk is still under warranty conditions, you can request the vendor maintenance, if not in warranty period, it is only to spend some money to give professionals repaired!

What should to do if OS does not recognize SATA drives

manyu — Sat, 02 Jan 2010 00:54:34 +0000

My computer’s motherboard chipset supports RAID function, fitted with a 60GB IDE hard drive, most recently in order to play games, upgraded a 160GB of SATA hard drive, but can not find the hard disk, Windows systems can not be properly installed.

In general, when install DOS/Win98/WinMe system, SATA drives do not need to load any drivers that can be used directly. Win2000/XP/2003 system is installed, if the motherboard Southbridge chip is not provided by the SATA controller set to RAID or RAID in the BIOS, shielded, they can find the hard disk drive; but the hard disk can not be found when open RAID function. RAID in the BIOS at this time will be turned off, and then in the process of installing WinXP, the bottom of the screen displays “Press F6 if you need to install a third party SCSI or RAID driver” prompt message, immediately press the “F6″ key, and follow the prompts to the system motherboard with the SATA driver floppy disk into the floppy drive, and then press the “S” key to load the necessary drivers.

Power On Self Test computer prompted “immediately back up the data stored in the hard drive and replace your computer’s hard drive, a failure will soon be occurring.” At this point you should do the following:
(1) Use the disk repair software (such as PQMagic) in DOS mode to check the hard drive, if it is damaged the data (such as the boot record is lost) and soft faults can be directly repaired, if the disk has bad sectors, you can use tools Bad Track software repaired or temporarily isolated.
(2) The subsequent re-partition and format the hard disk and reinstall the operating system operations.
(3) If the hard disk has bad sectors, re-zoning method of isolating the bad sectors are only temporary measure to deal with after the hard disk please send professional department maintenance (Prior to this, please back up important data to prevent loss).

When my hard drive read and write data, suddenly issued a number of abnormal sound and then crashes, and when the computer starts again, without any problems, but later found there has bad sectors, unfortunately I was a rookie, I am very worried about the rapid spread of these bad sectors, are there any simple way to isolate these bad sectors?

A: To simply solve this problem, can make use of the hard disk tools, here FBDISK recommend this software, it can have a bad track to automatically re-partition the hard disk will be bad track set to hidden partitions, and good track set is available partition will FBDISK software to copy a bootable floppy disk or U disk, use the boot disk to boot into DOS mode, the implementation of FBDISK.exe command will then display a prompt, press “Y” button after the software will search for hard disk damage, look after, FBDISK automatically Good sectors for partition, to confirm correct and directly choose “Y” to confirm. Restart the system, to format the partition, if the bad tracks are too scattered, and this creates many scattered available partition; limited to the zoning regulations could be established only four primary partitions, the program would choose the largest available set of four sub-partition, Others set to hidden partition

Operating System Can not Read Source File or Hard Disk

manyu — Mon, 14 Dec 2009 07:55:41 +0000

Operating System can not read source file or hard disk, this is frequently encountered problems using computers, Do not worry, we now have three ways to solve this problem:
Conventional solutions:
1, write-off or restart the computer, and then try to delete.
2, enter “Safe Mode to remove.”
3, in a pure DOS command line, use DEL, DELTREE and the RD command to remove it.
4, if there are more folders or files in subdirectories result can not be removed, they may first remove the folder in the subdirectories and files, and then delete the folder.
5, in the Task Manager end of the Explorer.exe process, and then delete the files in the command prompt window.
6, if you have installed ACDSee, FlashFXP, Nero, Total these software, you can try the software to delete these folders.
2, Advanced Solutions:
1, disk error
Run ScanDisk and scanned documents where the partition has been chosen before the scan to determine the fixed files and bad sectors, full scan all the options, scan and then delete the text of Ren.
2, pre-reading mechanisms:
Some media players suspended or are in the preview cause can not be removed. In the “Run” box, enter: REGSVR32/USHMEDIA.DLL, written off read-ahead feature. Or delete the following registry key: [HKEY_LOCAL_MACHINE \ SOFTWARE \ Classes \ CLSID \ (87D62D94-71B3-4b9a-9489-5FE6850DC73E) \ InProcServer32].
3, Firewall:
As the anti-virus software to check narcotics will be occupied by the file is being checked, resulting in prompt implementation of the deleted file is in use, when to try to temporarily close its real-time monitoring program, perhaps can be resolved.
4, OFFice, WPS Series Software:
OFFice can also cause the illegal closure of the file can not be deleted or renamed. Re-run the program, and then shut down properly, and then delete the file.
5, using WinRAR:
Right-click the folder you want to delete and select “Add to the compressed file.” In the pop-up dialog box select the “Delete source file after compression,” casually write a compressed package name, point to determine.
6, permissions problem:
If it is 2000 and xp systems, make sure whether there is permission to delete this file or folder.
7, executable Tou parts deleted:
If the image of the executable file or program called by the DLL dynamic-link library file is still in memory is not released when you will be prompted to delete the file is in use, the solution is to delete the system page file, Win98 is Win386.SWP, Win2000 / XP is the pagefile.sys. Note that the deletion in DOS.
8, file crushing method:
Use file shredders, such as FilePulverizer, you can completely remove some stubborn files.
Third, make a not delete the “File Safe”
Folder can not be deleted, is not necessarily a bad thing, if some important files on this directory, do not be avoided mistakenly delete it? A file name contains only spaces in the Windows folder is not allowed to create and delete, but they can be created under the DOS file name contains \ folder

“Replace Hard Drive; Failure Is Imminent”

Start computer pop”Replace Hard Drive; Failure Is Imminent“. May be the following questions

(1) a bad hard drive if the CMOS could not see the hard disk argument, try to re-insert the battery plugs look hard line and not act like a bad hard drive change

(2) If the hard disk is generally not a bad system or partition problem the case of system problems can be re-systems

(3) If the district does not resolve to a damaged, could be the next “easy, I Disk Doctor,” and do some (4) If the system does not resolve the district may be bad sectors, and may be the next DOS scan with MHDD look, in the case really has bad sectors, it was suggested to replace the hard disk .

Recommend a tool, Dformat, low-grid tool, look for how to use online, there will be a. Should be able to repair your hard drive, but time is very long, as long as your hard disk is not flawed, if flawed,only to change the hard disk.
