1. Computer’s system time allowed
【Symptoms】 a compatible use for a long time, every time the system is started from January 1, 1998 when starting to
【Failure Analysis and Treatment】 usually BIOS can automatically charge, so there the main reason for this failure may be the CMOS battery is damaged, simply replace the CMOS battery, the fault will be excluded.
2. Floppy drives can not read and write
【Symptoms】 start a computer when the floppy into the floppy drive self-test light, but it prompted floppy drive not found. After the normal startup hard disk is not read / write the floppy drive.
【Failure Analysis and Treatment】 suspect that it was the first floppy drive is damaged, then remove the floppy on another computer has received the use of normal, replace the floppy drive to another well received in the computer, there is still the same failure. Also suspected of multi-function card is damaged, but the card got on the test but no other computer problems, with a good multi-function card for replacement, fault still exists. So he suspected the motherboard failure, and the most likely damage the BIOS chip, replace with substitution after the BIOS and found no damage to them, only to power on the motherboard CMOS battery removed, so the information in Canon NB-9L battery CMOS is lost completely after relevant information and then re-set, fully restored;
3. A drive boot prompt, B type of drive configuration error
【Symptoms】 A drive one, B drive are used in computers, A floppy disk drive 1.44MB floppy drive for use, B invulnerable to use 1. 2MB floppy disk in the floppy drive. Configuration in the CMOS entirely correct, but the boot drive was prompted to A, B type of drive configuration error.
【Failure Analysis and Treatment】 repeatedly checking the contents of CMOS configuration not found any problems, replace the floppy disk drive and multi-function card is also no problem, then suspected infections each CMOS, will reconfigure the board after discharge and did not solve the problem. Configuration information will then try to type to two other types of floppy disk drive, floppy drive when the two are into 360KB floppy, the boot floppy will not prompt an error, this may be due to the communication line connected floppy drive problem After re-for-one communication line failure,
4. Failure does not recognize the floppy disk in the floppy drive to use
【Symptoms】 a computer in the course of the floppy disk read / write operations, the following tips:
General Failure Reading Drive A: Abort, Retry, Fail?
【Failure Analysis】 belonging to an error in equipment, if you choose A, said exit, R to try again, F is failure turned to another drive, have caused the error has the following main reasons:
Capacity of floppy disks are not compatible with floppy drive
With the DOS command read / write floppy disk, the need to take into account the compatibility of floppy disks and floppy drive. If it is 720KB floppy, and 1.44MB floppy disk into the message will appear above the 3.5-inch 1.44MB floppy drive, but can be properly read / write two kinds of 720KB and 1.44MB floppy disk. Similarly, 1.2MB 5.25 inch floppy drive can properly read and write both 360KB and 1.2MB floppy disks, the will not be allowed back;
Floppy boot sector damage
Improper operation due to a virus or other boot sector of floppy disks destroyed in the read / write disk read error occurs, the software tools available on the floppy disk repair;
No software to format the floppy disk
To giving and receiving for NIKON EN-EL14 battery DOS disk format is divided into several sectors of the disk is not formatted floppy disk can not be read / write operations. Floppy disk is not formatted for read / write operations when prompted. As long as DOS, or system to format the disk and then read / write operations can be;
Floppy drive type set incorrectly in CMOS
Stored in the CMOS when the computer work to set the parameters of each device, if the parameters in the CMOS settings wrong, will also appear in the operation of the device the above problem, if it is 1.44MB floppy drive, and was set in the CMOS or 360KB 720Kb and so on, read / write 1.44MB floppy disk, that will appear above error;
Tip: in the floppy drive in the CMOS set to “NOT INSTALLED”, then into the read / write disk, there will be no floppy disk in the tips, as long as the settings in the CMOS parameter settings to restore normal floppy drive, this problem does not occur ;
5. Floppy drive is not detected when you start your computer
【Symptoms】 start the computer, the display “floppy disk (s) fail (40)” error message;
【Failure Analysis and Treatment】appear “floppy disk (s) fail (40)” or the A: drive error in the message, have not checked that the motherboard BIOS the floppy hardware, floppy drive most of this situation due to hardware failure, The specific solutions are as follows:
Check the floppy drive connector on the motherboard and the floppy drive data cable and power lines, if not found the problem, you can access other computers on the floppy drive test to check if the floppy drive using the normal CMOS settings on the floppy, check the CMOS of the “integrated Peripherals “,” onboard Fdc Controller “item is set to the” Disabled “, if it is set to change this situation” Enadled “to troubleshoot problems;
6. Floppy drive light stays off
【Symptoms】 after boot, there “Floppydisk (s) fail (40)”, and the floppy drive light stays off, changing some Sony NP-BN1 battery BIOS settings did not help. The floppy drive somewhere else to normal use, the new floppy drive on this computer is also light does not.
【Failure Analysis and Treatment】reproduce this failure was mainly due to CMOS settings wrong, floppy drive power cable does not work. The solution is: Boot, press [Del】 key to enter the BIOS setup program to set “INTEGRATED PERIPHERALS”,, “Onboard FDC Controiler”, this option is set to “Enabled” then.
7. Can not write data to the floppy disk
【Symptoms】 floppy disk for the protection of mouth is open, still can not write data to floppy
【Failure Analysis and Treatment】correctly read data because, there is a hard format floppy drive can be ruled out the possibility of failure. In the system boot into the CMOS settings, check the “Floppy access Contrl” (floppy drive access control) is set to “Read-only”, if so it certainly is “Read-Write” after troubleshooting.
8. CMOS setting error caused by hard disk failure
【Failure Analysis and Treatment】CMOS drive type in the correct or not directly affect the normal use of the hard disk, and now the computer can not support the “IDE Auto Detect” feature that can automatically detect the hard disk type. When the hard disk type error, there will not start the system or the occurrence of read / write errors. Such as hard drive type in CMOS is less than the actual hard disk capacity, the hard drive behind the sector will be unable to read / write, if it is more a state of the individual district competition area will be lost.
In addition, because the IDE has support logical argument types, the hard disk can be Normal \ LBA \ large, etc., if the installation of three-mode-like data, but CMOS in abundance for other models will occur Hard workshops / Write error because the mapping has changed, and will not be able to read the original location of the correct hard drive.
9. CMOS stretch power failures caused by hard disk
【Symptoms】computer boot prompt appears on the screen “Device error” prompt.
【Failure Analysis and Treatment】This is mainly caused by the CMOS power stretch from the abundance of information loss. The right way to deal with in accordance with the following: First open the Casio NP-120 battery case, observe the battery is loose. If so, will be fixed and then boot; If not, you may have a battery failure, a good battery for the block, re-set the CMOS parameters, can be a normal hard drive started.
Tip: If you can not start properly, it should be reversed because the data lines caused.
10. Type parameter error caused the old hard disk failure
【Symptoms】 host starts, the internal self-test is completed, “beep” horn ring twice, the screen appears: “C: Drive error” and other erroneous translation of films, with a floppy boot disk does not start successfully, tried to enter the hard drive, appear: “Invalid media type reading drive c Abort, Retry, Fail?” error message.
【Failure Analysis and Treatment】: This occurs because the hard disk parameter values do not match due to Type, Type meeting is a characteristic sign of the hard disk, hard disk capacity on behalf of the size, number of heads, heads, and the equivalent number of sectors. If the Type value set incorrectly, the drive will not start, the solution is to re-set the hard disk of the Type value.
After the boot to be self-starting, press 【DEL】 【key or press the ALT + CTRL + ESC】 key combination to enter the host parameter table, DriveC: (drive C:) part of the “Type” item, Type the value you can enter the correct
11. Suddenly can not boot the hard disk
【Symptoms】 one compatible with the 3-year, when a sudden start: “Disk boot failurt, Insert system disk and press enter” prompt can not boot the CANON BP-511A Battery system.
