hard-disk-failure-and-repairCompared with physical data recovery, logical data recovery can be easier to handle. The following error messages displayed on your screen usually stand for some data corruption or hard disk failure. To understand what they mean helps us find the best method to clear such errors and failures and find our data back.

Error message 1: “Sector not found reading drive”

This message can appear during any DOS operation. Generally, it is caused either by fading or the loss of a sector ID.

Error message 2: “Data error reading drive”

This message can appear during any DOS operation. It is caused by failing the data check – CRC (Cyclic Redundancy Check) or ECC (Error Correction Code). This “Data check” refers to the mechanism used to check whether the data read from the disk is reliable.

Error message 3: “ 0 hard disk(s) found”

It is displayed if the hard disk is not detected by the BIOS of the computer. Check the power and data cable connections of the hard disk. If connections are all right, the problem may be due to some hardware error of hard disk.

Error message 4: “Hard Drive failure, press F1 to continue”

It is displayed if the hard disk is not detected by the BIOS of the computer. Check the power and data cable connections of the hard disk. If connections are all right, the problem may be due to some hardware error of hard disk.

Error message 5: “Invalid drive specification”

It is displayed in the condition when either the system does not recognize the hardware, or there is no partition information, or the device driver of the drive is missing.

Error message 6: “Invalid configuration press F1 to continue”

If the hard disk is available, Either the battery in the motherboard is dead, and the system has lost its configuration SETUP information or the disk is not responding.

Error message 7: “Invalid partition table”

This is the MBR error message. It is displayed when the partition table of the MBR does not have the valid partition information.

Error message 8: “Error loading operating system”

This is the MBR error message. It is displayed due to any type of MBR information corruption.

Error message 9: “Missing operating system”

This is the MBR error message. It is displayed due to any type of MBR information corruption.

Error message 10: “Disk boot failure”

It is the DBR error message. Normally, The Hard drive should be accessible if you boot from the floppy. Though it is not bootable but that should not affect the access to the data of the drive.

Error message 11 : “non system disk or disk error”
It is the DBR error message. Normally, The Hard drive should be accessible if you boot from the floppy. Though it is not bootable but that should not affect the access to the data of the drive.

Error message 12 : “Bad or missing command interpreter”

This message is displayed due to Bad or Missing Command Interpreter. For example if the operating do not find the command.com in current path or the command.com is corrupted.
