Need to the loved ones ever hear such a sentence: ten auto accidents and nine quick, and also the pc

Below, let's check out the standard failures and repair strategies with the really hard disk:

1. Why does the BIOS not detect the difficult disk?

In the event the BIOS can not automatically detect the challenging disk, you can find normally the following four motives:

◆ The challenging disk is not installed properly. At this time, the first factor we have to do will be to verify regardless of whether the data cable and energy cable from the tough disk are installed appropriately? Under regular circumstances, it might be brought on by the truth that it has been inserted into the corresponding position, however it just isn't properly placed. At this time, certainly, the difficult disk cannot be detected.

◆ Jumper (jumper) will not be set appropriately. If your laptop is equipped with dual hard drives, you'll want to set among them as the master hard drive (Master) and also the other because the slave difficult drive (Slave), if both are set as master hard drives or both are set as slave challenging drives , You connect the two hard disks towards the IDE slot of the motherboard using a information cable, then the BIOS can't detect your really hard disk details properly. It is ideal to work with two data cables to connect to the two IDE slots in the motherboard, so that you are able to make sure stable operation even if your hard disk interface price is unique.

◆ The hard disk and CD-ROM are connected to the exact same IDE interface. Normally, provided that we set it properly, connecting the difficult disk plus the CD-ROM to the same IDE interface might be okay, but there can be some new CD-ROMs that should conflict with the old really hard disk, so it's safer to connect them separately.

◆ Physical harm towards the challenging disk or IDE interface. In the event the hard disk has been installed correctly, along with the jumper is set appropriately, and the CD-ROM is not connected to the very same IDE interface because the hard disk, however the BIOS nonetheless can't detect the difficult disk, then the greatest possibility is that the IDE interface may be faulty, you are able to try Attempt an additional IDE interface. If it still doesn't operate, then I'm afraid that your hard disk features a dilemma. You should connect it to a different laptop or computer to attempt it. If it can be appropriately identified, then the IDE interface is faulty. If it nevertheless cannot be recognized, It indicates that there's an issue together with the tough disk; it is possible to also install it on your personal computer with a further new difficult disk or perhaps a operating really hard disk. If the BIOS can't recognize it, it implies that the IDE interface of your computer system is faulty. If it may be identified, it means that the original hard disk does malfunction.

two. Realize popular really hard disk failure information recommendations

We are able to understand the frequent tough disk failure facts by way of the following table, to ensure that we are able to have a clear heart when judging!

The fault message prompts the specific meaning, causes, solutions

Nopartitionbootable No partition table The challenging disk will not be partitioned or the partition table data is lost (could be attributable to a virus). Antivirus initially, after which use FDOS to re-partition soon after executing FDISK command.

NOROMBASIC or PRESSKEYTOREBOOT can't come across the boot technique with no setting the active partition (setactivepartition), usually do not rule out the result in with the virus, first kill the virus, after which re-run FDISK and set the active partition.

Missingoperationsystem can not find the boot system really hard disk just isn't formatted or lost 3 big file systems Formatc: / s or sysc:

Non-systemdiskordisk Non-system disk or disk error Use non-system disk to boot Remove the floppy disk to boot with the hard disk or insert the technique disk.

Badormissingcommandinterpreter or command.comisbadcommand.com file reading error or missing command.com file was deleted on account of misuse, or virus damage. Copy the command.com file for the really hard disk, or just use the SYSC: command to transfer the file. You could also use tools which include NDD to repair.

CannotloadCommand.com, systemhalted failed to load command.com file is broken or the version of command.com file will not be compatible with boot system. Recopy the file for the difficult disk, but often antivirus is required. DISKBOOTFAILURE difficult disk boot failure has a lot of reasons. It might be that the hard disk has a difficulty. Take the tough disk to yet another machine and try it. If everything is regular, it means that the motherboard IDE interface is faulty. 3. The hard disk can't start with out any error message

Encountering this circumstance will be the most annoying point, for the reason that it is hard to judge the fault. We usually use the replacement approach, initially make use of the DOS system disk to start from A :, just after A: \\, variety C: \\ to switch to C: disk, if there's an Invaliddrivespecification error message, it indicates that the hard disk MBR (master boot record) failure; InvalidmediatypereadingdriveC: error message appears after DIR: the DBR (DOS boot record) failure from the difficult disk; in the event the file name, size, date and also other details can be displayed correctly soon after employing the DIR command, indicating that the file is normal, please transfer the file inside the tough disk straight away , Then repartition and format it.

four. The issue of crossed drive letters soon after installing dual really hard drives

Friends who set up dual really hard drives frequently encounter the issue of drive letter crossover following getting into Windows 98, especially when each hard drives possess a master boot partition. At this time, you will discover that Windows 98 is definitely the main boot partition on both really hard drives. Putting them collectively, and ordering other partitions in order, this causes the phenomenon that the drive letters are misaligned, causing inconvenience to our operation. That is due to the fact Windows 98 will not officially support dual tough drives (Windows 2000 could be well supported, it truly is encouraged that mates upgrade). The easiest strategy to resolve this problem should be to enter the BIOS setup system, set the second difficult disk to NONE, and after that enter Windows98 again, you'll find that the drive letter is misaligned, we can effectively access the two tough disks, use the sources in it, Certainly, the author thinks that the most beneficial way is always to use Windows2000 technique, let it automatically handle dual hard drives, which is worry-free and protected.

5. UltraATA / 66 really hard disk can not select DMA option

This really is basically not a hard fault, but can only be said to be a soft fault, but the author normally encountered numerous friends asking me for suggestions that the UltraATA / 66 mode couldn't be turned on, which created the advanced challenging disk interface technology unusable, which was a great waste. system resource.

Right here, we can go over it in two circumstances: one is usually to use the Windows 2000 operating method. If a challenging drive that supports UltraATA / 66 is installed in the method, it's going to automatically make use of the UltraATA / 66 mode without any settings (the method has The default settings are set, as long as you enter the device manager window, double-click PrimaryIDEchannel under the IDEATA / ATAPI controller item to enter the property setting window, set the tough disk device sort to automatic detection inside the sophisticated settings tab, and set the transfer mode to DMA (If readily available), set the SecondaryIDEchannel once more, after which restart it.); But in the event you are utilizing Windows98, due to the fact Windows98 does not assistance UltraATA / 66, you need to install a patch (this patch is frequently in On your motherboard driver CD), you may turn on DMA following installation. But when you are employing a motherboard with By way of chipset, the installation of Via four-in-one driver is inevitable. more info can download the newest By way of four-in-one in the driver home http://www.mydrivers.com A driver package, the latest version is now four.26, just after downloading is a compressed file in ZIP format, unzip it and uncover Setup.exe in it to set up. On the other hand, the installation of this four-in-one driver is very tricky, which involves the issue of custom installation settings plus the separate installation of your IDEBUSMaster bus. When the installed program meets the following two conditions, it can be said that the UltraATA / 66 mode has been turned on:

◆ The really hard disk information and facts in Device Manager has been appropriately identified.

◆ The DMA check box in the device manager is no longer visible. In data recovery software free download , you could set whether or not to open or close UltraATA / 66 from the VIADMATool system. The VIADMATOOL plan has taken over the UDMA device inside the method.

Generally, tough drives are generally not prone to failures, but as soon as they seem, they're incalculable losses. Hence, data recovery software hope my good friends nevertheless spend attention for the backup and upkeep of the method, and in the exact same time strengthen the virus monitoring to make sure the stability on the difficult disk to the greatest extent.
