解决硬盘引导型故障（Hard disk boot fault）

Hard disk boot type fault analysis and troubleshooting

The hard disk is an important medium for storing information.

When the hard disk fails, it is a very important task to quickly

identify the cause of the failure and eliminate it. Here is the

analysis of the fault outside the virus as follows:

1, HDD controller failure (hard disk drive control failure)

After the POST program sends a search command to the drive, the

driver causes a timeout error without completing the operation

within the specified time.

C:drive faiIure (hard disk C driver failed)

RUN SETUP UTTLITY (run setup function)

Pressto Resume (button restart)

This kind of fault is generally due to the type settings of the

hard disk, and the parameters do not match the parameters used

in the original format. The parameter setting of IDE hard disk

is the logic parameter, so in most cases by the floppy disk,

the C disk to read and write properly, just can't start.

2, fault information: lnvalid Drive Specification (invalid

drive specified)

This is the partition or logical drive that you want to operate,

and is not defined in the partition table at all. If a partition

or logical drive does not already exist in the partition table,

the partition or logical drive does not exist for the operating

system. The problem must first be found in the partition table.

The easiest way to fix this kind of failure is to backup the

partition tables in advance, such as using the Pctools9.0

Bootsafe tool, and of course, to recalculate the partition

tables based on the data in the BPB table, but it's more complex.

3, Ertor, Loading, Operation, System (load OS error)

This type of fault is indicated when reading the partition boot

sector (BOOT zone) error. The possible reasons are as follows:

first, the partition table indicates that the partition start

physical address is incorrect. For example, the partition table

is third bytes (starting sectornumber) changed from 1 to 0,

which indicates the starting address of the partition for the

specified indicator head, on the track of the zeroth sector (the

physical address, by the 1 sector began to read the disk 13H

INT), after the failure of this newspaper is wrong. Second 、

the track mark and sector ID of the track in the zone boot sector

are damaged, and the specified sector cannot be found. Third

driver read circuit fault. This is a rare situation, most of

which are random read errors, because system boot can be carried

out here, at least indicating that a master boot sector has been

correctly read out.

4, can not enter the system, if there is floppy drive, then drive

by A drive, display:

DRIVE NOT READY ERROR (device not ready)

Insert, Boot, Diskette, in, A: (insert boot disk to A drive)

Press any key when ready (press any key when you're ready)

After the BIOSPOST is finished, if it is booting by the hard

disk, the system will read the 0 sides of the hard disk, 0

sectors and 1 sectors, looking for the main boot program and

the partition table. Therefore, it is impossible for any

software to try to avoid the 0 or 0 channels of the hard disk

damage and successfully boot the operating system! Unless you

rewrite the instructions in the system BIOS INT 19H.

INT 19H reads the main boot sector failure for the following

reasons: first, the hard disk reads the circuit fault, causing

the read operation to fail,

A hardware fault; second, 0 and 0 track format sector ID logical

or physical damage, could not find the specified sector; third,

read the disk without error, but the read MBR tail marked as

"55AA" system that MBR is not correct, this is soft fault.

5, NonSystem Disk or Disk Ertor

Replace, And, press, any, key, when, ready (non system disk or

disk error, press any key after relocation)

After the bootloader in the DOS BOOT zone is executed, an error

is found, and this information is reported. Possible cause:

drive reset failed, root sector first sector address out of

bounds (after 544M), read disk error. Such failures are mostly

software failure, if the BPB table is damaged after the floppy

disk, hard disk cannot read or write, you can use the NDD repair;

if the BPB form intact, simply SYS C: transmission system boot

device, if failure is shown:

Disk Boot Failure (disk boot failure)

6, NO, ROM, BASIC (without curing BASIC)

SYSTEM HALT (system shutdown)

This is a fairly old machine that will show that the main

bootstrap function is to find an active partition (a

bootstrapped partition) in the four table entry of the

partitioned table. If none of the four table entries activate

the partition, the system does not know where to boot the

operating system, and can only execute INT 188H, calling the

solidified BASIC program, which will cause a crash if the BASIC

is not solidified. The easiest way to fix it is to specify a

bootstrapped partition with the second function of FDISK: Set,

activeparti, tion (setting activation partition).

7, display the Starting of MS-DOS and "

In the recovery of hard disk can guide the soft fault, a final

note, and in the executable file itself

has been damaged, the system crashes in the implementation of

this file, the screen prompts: "" And then

crash. The fault is very simple, but because there is no fault

information, it is easy for ordinary people to misjudge the

system files. When this phenomenon occurs, and make sure that

the file system is intact, take off the two files, or more

information on the screen, press the button or press the button

(fast interrupt installation and execution of

), or press the button (step command),

to find out the damaged file.

8, Invalid, Partition, table (invalid partition table)

Find the activation after the partition, the master boot

program will also determine the remaining three entry "boot

flag byte (the first byte) are 0, that is to confirm whether

there is only one active partition, if one is not 0 (normal value

only for 00H and 80H), the system error and crash.

9, Bad, or, missing, Command, Interpreter

Enter cortect, name, or, Command, Interpreter (command handler

error, please enter the correct file name)

The system cannot find the command handler in the root directory

and the specified directory. It asks the user to enter the

correct path and file name. You can enter it at the prompt,

For example: C:.

10, Invalid, Media, Type, Reading, Gnive, X

Abort Retry, Fail (read X drive media type is invalid)

This information is prompted for an invalid BPB table in the

DOS BOOT zone. The BPB table is the logical address used by DOS

to read and write the hard disk. The bridge that converts the

physical address to the BPB table is corrupted and will make

the DOS difficult to talk about the disk operation.

The boot type soft fault of the hard disk can be checked by the

sequence shown in the block diagram: the main boot program in

the main boot sector - the boot program in the partitioned BOOT

zone - the DOS system implicit file - CONFIG AUTOEXEC.

When the hard disk read and write (with no problem after the

floppy disk can read and write properly), not only guide system,

four local fault point must shown in the previous frame, check

the order of the master boot program, partition boot program,

DOS system, CON hidden files and . For the

main boot in the main boot sector, FDISKMBR can be forced to

write a correct backup. For boot and system implicit files in

partitioned BOOT, the SYS C: transport system can be used to

override the error data (provided that the BPB table is intact).

For hard disk read and write failures, there are only two

possible fault points: the partition table and the BPB table.

If you use the floppy disk, to be sure the C C: prompt, partition

table exists and is basically intact; if the C normal read and

write, BPB certainly is good. The reader may recover according

to the method described earlier or by other appropriate tools.

11, 17XX, Hard, Disk, Ertor

HDC controller fail (hard disk controller failed)

This type of fault is a hardware fault. After the POST program

issues a reset command to the controller, the controller does

not receive an interrupt response within a specified time,

possibly because of a controller damage or a cable failure. The

controller failed and the hard disk parameter settings are

correct
