General Hard Disk Problems


-->
Problem
The new operating system installer does not identify the hard disk.



Remedy


Switch off the computer. Remove the power cable. Open the cabinet.


Check whether the hard disk power and data cables are connected properly.


Change the hard disk power cable and check if it is identified in the CMOS setup.


After confirming whether the hard disk is listed in the CMOS setup, boot the computer with the Disk manager bootable disk.


Using disk manager, create a partition and prepare the hard disk.


Now start the operating system installation.


The Operating system will now identify the hard disk.


Problem



Unable to delete or create partitions in a hard disk.

Remedy



Check whether the hard disk is identified by a disk utility like FDISK.


A Partition table virus may cause this kind of problem.


Boot with a clean boot floppy and scan the hard disk for a virus infection.


Even after this, if the partitions cannot be modified, use Disk Manager.


Using Disk Manager, you can edit the Partition table and create / delete partitions.


Check whether the hard disk is working or not, by using the disk manager software.




Problem

No display after connecting a new hard disk

Remedy



While fixing the hard disk, there is a chance that the power on switch connector wire from the front panel may be disconnected. Check whether it is disconnected.


The memory modules may be disturbed while installing the hard disk, this should be checked, if there are beeps while switching on the computer.


The IDE hard disk cable may be connected in reverse.


Remove the IDE cable and connect it correctly.


If this channel has not been used previously, try to connect the hard disk to another channel and check the display. Also change the IDE cable, if doubtful.


Now the hard disk will be detected and the system will function normally


Problem



After connecting a second hard disk in the primary channel (IDE0), no hard disk is detected.

Remedy



All new IDE hard disks are distributed with jumper settings for working as a master disk.


The previous hard disk may also be configured and working as a master disk.


If the new hard disk is connected to a cable where another master hard disk is connected, then both the hard disks will not be detected by the BIOS.


Remove the new hard disk and reconfigure the jumper to either make it as a slave or use the jumper settings for cable select.


Now connect and use BIOS to identify the master and slave hard disks.


Problem



Hard disk is not detected, even after changing the old one.

Remedy



Switch off the power and disconnect the power cable.


Open cabinet and check whether the power and data cables are connected properly.


Connect another power cable and a new data cable to check if it is identified.


If the hard disk is identified, then the problem is due to the data cable.


If the problem is not yet solved, then follow the next step.


Some old motherboards will not support hard disks with a large capacity.


If you have installed a new hard disk, then remove the hard disk and install it in another computer. Observe if it is working or not


If it is working in another computer check the motherboard manual /website for any available BIOS updates. Otherwise get a hard disk with a lower capacity and install.
