IBM server hard drive FAQ and troubleshooting (1)

The system BIOS does not correctly recognize the IDE hard disk.

If the system BIOS does not correctly identify the IDE hard disk, check whether all hardware devices, disks, data lines, or motherboard are working properly.

1. If a controller works properly on another motherboard, connect the hard disk to the Controller and check whether the hard disk can be identified in the BIOS.

2. Re-unplug the hard disk data and power connections. If possible, try other data and power cables.

3. Check the Jumper settings of the disk. Master, Slave or Cable Select)

-Some hard disk manufacturers have designed two simple jumper methods for hard disks, which can be set as Master and Slave hard disks.

-Some hard disk manufacturers have designed hard disks so that they can jump to a Single Master hard disk. The Master hard disk includes a Server Load balancer hard disk or a Server Load balancer hard disk. If a new hard disk is added to the system, make sure that the Jumper settings for the Master hard disk are correct. For details, refer to the hard disk user manual.

-In the new system, the jumper of the hard disk is usually set to Cable Select, which can be adjusted as needed. All devices connected to the channel must support the Cable Select function, and all devices connected to the channel must set the jumper to the Cable Select function.

4. If the hard disk uses sound insulation or shockproof insulator, use a taper or patch cord connection between the hard disk and the chassis to ensure that the hard disk is fully grounded.

5. Disconnect the two controllers from all the other IDE devices connected to them, set the hard drive jumper to Master, and connect to the primary controller.

6. Remove other adapters inserted on the motherboard.

7. check whether there are damaged pins on the motherboard IDE controller and hard disk.

8. check whether there are broken cables. Make sure that the connection cable does not interfere with the hard disk when the chassis is closed.

9. Check whether the hard disk is working on another machine.

10. Check whether other hard disks are working on this machine.

11. check whether there is any upgrade microcode for this hard disk.

Hard Disk with noise

If the hard disk emits abnormal friction or continuous tick noises, you usually need to replace the hard disk. There is no need to use PC Doctor for detection. However, the design of some hard disks determines that there is a bit of noise in use. Occasionally, there may be some hard disk noises caused by incorrect installation. Such noises are usually large, but do not replace the hard disk before the diagnosis program confirms that the hard disk is indeed faulty. The application software provided by IBM may prompt "imminet failure temporary error" during diagnosis. The hard disk with this information may be considered faulty and replaced.

The following information will help you diagnose your hard disk and determine whether it is damaged and whether it needs to be replaced. Follow these steps:

Hard Disk fault description

-Hard disks cannot be properly identified or detected in the system

-When the server is started, the message "Insert system diskette" is displayed.

-When the server is started, a blank screen with a blinking cursor appears after the ibm bios.

-When the server is started, the error message "Bad partition table" appears.

-When the server is started, it stops on the ibm bios screen.

-You cannot run the FDISK command or format the hard disk.

-When formatting the hard disk, the message "Bad cluster" is displayed.

-An error message is displayed when the. ZIP file is decompressed.

-Abnormal noises on the hard disk

-When the server is started, the hard disk indicator is on, but the system does not start properly.

-When the server is started, a POST error 1762 error occurs.
