HARD DISK ERROR

HARD DISK ERROR





4. Two hard disk have been installed in a computer but only one is working.

·     If both the hard disks are connected by the same interface cable, then one of the two should be made master and the other one should be made slave. And which jumper will make the disk, it is also written on the top cover of the hard disk. If this information is not available then trial & error method should be adopted.

·      Both the hard disks are connected to the same cable and the master disk is working, but the second disk which is the slave is not working, even if the  slave is not detected, then its cable connection, power connection and slave should jumper setting. Detect the check by making master and master as slave, if still the disk made slave is not being detected, then try replacing the data cable. If detection is not happening even after replacing the cable, then it means that both the hard disk will not work by a single cable, the are getting mismatched, so connect them by different cables and the one who wants to make c drive is called pri from IDe and d: drive to sec.connect to the IDE.

·       ON connecting two drives, the hard disk which is not working, get it detected once independently by making single drive (by disconnecting the other hard disk), even then if it is not being detected then hat hard disk itself is bad.

·    When two hard disk are connected in the same cable as master/ slave, then hard disk mismatch can also happen due to different brand and capacity of hard disk, in which case only one hard disk will work, or one hard disk will work. Disk will become master only. To overcome this problem, both the hard disks should be connected by separate cable.

·    272 MB when Seagate’s hard disk is detected in BIOS, it may not work in LBA mole, so get it detected in normal mode. Maintenance of hard disk.

·    Hard disks are mainly available from Seagate brand only and hard disk of this of this brand can be available in scrap or defective. In such a situation, if Seagate’s hard disk crashes and its electronic circuit is damaged, then its circuit can be repaired by replacing it with another disk of the same brand and size touch.

·       Hard disk should be handled very carefully. Before touching it, the static should be discharged from the body by touching the wall itself.

·   To carry the hard disk anywhere, only the antistatic plastic case available for it should be used, in this it remains completely safe.

·  The hard disk should not be taken anywhere by keeping it in the trunk of the vehicle, otherwise it will crash with a little jerk or bad sectors will be formed in it turn on.

·   After doing all the connection to the to the hard disk, power on the hard disk by keeping it on a non-conducting material, always check its circuit side by keeping it upwards.

·    While putting the hard disk in the cabinet, tighten all its screws so that there is no jerk in it.

·     If the hard disk LED continues to glow after turning on the system, then it means that there is a problem with the hard disk, when the hard disk is fixed, the HDD LED should turn on and turn off in a few seconds as soon as the system is turned on. A proper hard disk makes less noise while working. But the hard disk whose media had bad sectors makes more noise while reading/writing.

·       Some old and low capacity hard disks also make more noise.

·     Currently voice coil is used to move the head of hard disk which make less noise. Older hard disks used to have stepper motors which used to make a lot of noise in doing R/W.

·  A maximum of 20GB hard disk can be installed in Pentium. Some hard disk mismatch with some motherboard, they will not be detected in CMOS or will show wrong size when detected and will not boot.

·    The power connector that is giving power to the hard disk should not be loose at all, otherwise it will often be off/on In the middle of doing work and bad sectors will be formed in it.

·   The main reason for the crash of hard disk is not getting constant power to the system. Always run the system from UPS, in this case HDD is very safe. Always do proper shut down, do not keep copying files of movies and songs in hard disk itself. To play them, the head of the hard disk requires more movement, this reduces the life time of the hard disk.

·   Do not forget to run the system with automatic stabilizer with relay switch, it increases the chances of crashing the hard disk.

·    Never open a correct hard disk out of curiosity, do not try to repair the hard disk which had bad sectors but is working by opening it at all. There is only replaceable electronics circuit in the hard disk, which can be easily replaced without opening the mechanism of the high disk. Otherwise repairable hard disk can be repaired only with diagnostic/utility tools software.

·     To know at which place there are bad sectors in hard disk, make its entire space c drive by Fdisk and format by format command. The percentage ar which the counting stops for some time or the message of “trying to remove file allocation unit” start coming, at the same time the base sector should be understood. In such a situation, after knowing how many percent of the hard disk is bad sector, partition should be done again by Fdisk and in a separate drive of the area with bad sector and connect area should be selected in a separate drive.

·      Hard disk cannot be formatted in the first time after partition, but if the hard disk is made a slave and connected with another hard disk containing windows OS, then the hard disk can be quickly formatted when windows boots. Can be done. by this method a hard disk with a bad sector can also be easily formatted.

·   Partition the hard disk which contains the necessary data only after taking a data backup because the data is lost when the partition is erased.

·        If the partition (primary dos) of the hard disk has not been activated, then the hard disk cannot be made bootable.

·      Partition the hard disk of more than 2GB capacity through FAT 32, this feature is in the fdisk of win98. Otherwise the entire space of the hard disk cannot to be used.
