Troubleshooting Floppy Disk Drive or Hard Disk Possible damage Damage to the floppy disk drive ¬ The system displays the disk directory is not suitable ¬ The system can not be read from all drives ¬ wrong when reading floppy disks written on a PC the other Damage to the hard disk ¬ The system can not booting from the hard disk ¬ disk performance decreases Module 4 Repairs and Re-Setting System PC Melakukan perbaikan dan/ atau setting ulang sistem PC

42. Diagnostic procedures and trouble shooting floppy disk drive When reading the system disk in the floppy drive first, the information on the FAT and root directory will be copied to memory. A copy of this disegarkan akan reading the content of the diskette in the new. Replacement diskete line modifier resulted in changing the disk. If this type of problem occurs, check jumpers setting on the modifier line disk. Check the data cable and power (check the LED lights a flame in the drive) Head dirty drive (clean the drive head with the cleaning head) Possible damage to the series of logic drive (try to replace the drive with another) Possible damage to the controller (try to change the other controller) Due sesuainya not format the drive or disk is not appropriate. Try reading the other floppy disks. Module 4 Repairs and Re-Setting System PC Melakukan perbaikan dan/ atau setting ulang sistem PC

43. Diagnostic procedures and trouble shooting hard disk ¬ settings in the CMOS drive type does not match or lost (run SETUP and autodetect the hard disk type) ¬ corrupted boot track (re-install the boot track using the command SYS) ¬ BUFFERS in CONFIG.SYS is set too small (add / increase the value of BUFFERS in CONFIG.SYS) ¬ SCANDISK Run program to manage data in the hard disk. ¬ Interleave does not fit (do low-level format) Module 4 Repairs and Re-Setting System PC Melakukan perbaikan dan/ atau setting ulang sistem PC
