Should really the household ever hear such a sentence: ten vehicle accidents and nine quick, as well

Under, let's take a look at the standard failures and repair approaches in the really hard disk:

1. Why does the BIOS not detect the really hard disk?

If the BIOS can not automatically detect the really hard disk, there are ordinarily the following 4 causes:

◆ The hard disk will not be installed appropriately. At this time, the very first thing we really need to do will be to verify whether or not the information cable and power cable in the difficult disk are installed correctly? Under typical circumstances, it may be caused by the fact that it has been inserted into the corresponding position, however it isn't correctly placed. At this time, needless to say, the challenging disk cannot be detected.

◆ Jumper (jumper) will not be set properly. In case your personal computer is equipped with dual difficult drives, you'll want to set certainly one of them as the master challenging drive (Master) and the other because the slave hard drive (Slave), if both are set as master challenging drives or each are set as slave tough drives , You connect the two hard disks for the IDE slot with the motherboard with a information cable, then the BIOS cannot detect your difficult disk data properly. It's very best to work with two information cables to connect for the two IDE slots from the motherboard, in order that you'll be able to guarantee stable operation even if your difficult disk interface rate is diverse.

◆ The tough disk and CD-ROM are connected towards the exact same IDE interface. Normally, as long as we set it correctly, connecting the difficult disk and the CD-ROM towards the similar IDE interface are going to be okay, but there could be some new CD-ROMs that could conflict with the old hard disk, so it truly is safer to connect them separately.

◆ Physical harm for the difficult disk or IDE interface. In the event the really hard disk has been installed appropriately, and also the jumper is set properly, as well as the CD-ROM is not connected towards the very same IDE interface as the challenging disk, however the BIOS nevertheless can't detect the hard disk, then the biggest possibility is that the IDE interface may be faulty, you are able to try Try one more IDE interface. If it still does not perform, then I'm afraid that your difficult disk has a problem. You need to connect it to a further personal computer to attempt it. If diskgetor data recovery free download can be correctly identified, then the IDE interface is faulty. If it nonetheless can't be recognized, It indicates that there is certainly an issue with the tough disk; you could also install it in your personal computer with yet another new really hard disk or a working hard disk. In the event the BIOS can't recognize it, it suggests that the IDE interface with the laptop is faulty. If it may be identified, it suggests that the original difficult disk does malfunction.

two. Recognize common really hard disk failure facts guidelines

We can comprehend the common difficult disk failure info by means of the following table, so that we can possess a clear heart when judging!

The fault message prompts the specific which means, causes, solutions

Nopartitionbootable No partition table The really hard disk is not partitioned or the partition table information and facts is lost (could be brought on by a virus). Antivirus first, after which use FDOS to re-partition soon after executing FDISK command.

NOROMBASIC or PRESSKEYTOREBOOT can not locate the boot technique with no setting the active partition (setactivepartition), do not rule out the cause from the virus, initially kill the virus, and after that re-run FDISK and set the active partition.

Missingoperationsystem can not obtain the boot system tough disk is not formatted or lost three major file systems Formatc: / s or sysc:

Non-systemdiskordisk Non-system disk or disk error Use non-system disk to boot Eliminate the floppy disk to boot together with the difficult disk or insert the technique disk.

Badormissingcommandinterpreter or command.comisbadcommand.com file reading error or missing command.com file was deleted as a consequence of misuse, or virus damage. Copy the command.com file to the challenging disk, or simply make use of the SYSC: command to transfer the file. You'll be able to also use tools including NDD to repair.

CannotloadCommand.com, systemhalted failed to load command.com file is damaged or the version of command.com file just isn't compatible with boot system. Recopy the file for the challenging disk, but from time to time antivirus is essential. DISKBOOTFAILURE tough disk boot failure has many causes. best data recovery software might be that the hard disk includes a issue. Take the hard disk to another machine and try it. If every thing is regular, it implies that the motherboard IDE interface is faulty. three. The challenging disk can not start off devoid of any error message

Encountering this circumstance is the most annoying factor, for the reason that it is hard to judge the fault. We typically use the replacement approach, initial use the DOS system disk to start from A :, right after A: \\, sort C: \\ to switch to C: disk, if there is certainly an Invaliddrivespecification error message, it signifies that the hard disk MBR (master boot record) failure; InvalidmediatypereadingdriveC: error message appears soon after DIR: the DBR (DOS boot record) failure in the hard disk; when the file name, size, date and other info may be displayed correctly soon after working with the DIR command, indicating that the file is regular, please transfer the file within the really hard disk right away , And then repartition and format it.

four. http://bathexpert32.mystrikingly.com/ of crossed drive letters right after installing dual challenging drives

Good friends who set up dual difficult drives generally encounter the problem of drive letter crossover after entering Windows 98, specifically when each tough drives have a master boot partition. At this time, you will discover that Windows 98 is the main boot partition on both really hard drives. Placing them collectively, and ordering other partitions in order, this causes the phenomenon that the drive letters are misaligned, causing inconvenience to our operation. This really is mainly because Windows 98 doesn't officially assistance dual challenging drives (Windows 2000 can be well supported, it is recommended that pals upgrade). The easiest technique to resolve this challenge will be to enter the BIOS setup system, set the second difficult disk to NONE, then enter Windows98 once more, you'll discover that the drive letter is misaligned, we are able to successfully access the two challenging disks, make use of the sources in it, Of course, the author thinks that the ideal way is usually to use Windows2000 program, let it automatically handle dual tough drives, that is definitely worry-free and secure.

five. UltraATA / 66 tough disk can not select DMA selection

That is actually not a really hard fault, but can only be mentioned to become a soft fault, but the author often encountered several buddies asking me for tips that the UltraATA / 66 mode couldn't be turned on, which produced the advanced hard disk interface technologies unusable, which was a fantastic waste. technique resource.

Right here, we are able to discuss it in two instances: one is always to use the Windows 2000 operating program. If a tough drive that supports UltraATA / 66 is installed within the method, it's going to automatically use the UltraATA / 66 mode without having any settings (the method has The default settings are set, provided that you enter the device manager window, double-click PrimaryIDEchannel below the IDEATA / ATAPI controller item to enter the property setting window, set the difficult disk device variety to automatic detection inside the advanced settings tab, and set the transfer mode to DMA (If available), set the SecondaryIDEchannel once again, and then restart it.); But should you are using Windows98, since Windows98 doesn't assistance UltraATA / 66, it's essential to set up a patch (this patch is usually in In your motherboard driver CD), you are able to turn on DMA right after installation. But in http://listyellow41.iktogo.com/post/the-software-program-is-heredefragmentation--tough-disk-repair--data-recovery-1-defragmentation-tool are employing a motherboard with By means of chipset, the installation of By way of four-in-one driver is inevitable. Buddies can download the latest Via four-in-one in the driver house http://www.mydrivers.com A driver package, the most recent version is now four.26, immediately after downloading can be a compressed file in ZIP format, unzip it and come across Setup.exe in it to install. Having said that, the installation of this four-in-one driver is quite difficult, which entails the issue of custom installation settings along with the separate installation of your IDEBUSMaster bus. In the event the installed program meets the following two situations, it can be said that the UltraATA / 66 mode has been turned on:

◆ The tough disk information in Device Manager has been correctly identified.

◆ The DMA check box in the device manager is no longer visible. Furthermore, you can set regardless of whether to open or close UltraATA / 66 from the VIADMATool plan. The VIADMATOOL program has taken over the UDMA device in the system.

Generally, data recovery software for windows 7 are normally not prone to failures, but after they appear, they are incalculable losses. For that reason, I hope my buddies still spend consideration to the backup and maintenance of your technique, and at the exact same time strengthen the virus monitoring to ensure the stability in the challenging disk towards the greatest extent.
