Free Hard Drive Repair ISO to Common Hard Drive Failures

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.
