Hard Disk Failure Messages.

If you attempt to start your computer or access a hard drive and the computer gives you any of the following messages you most likely have a hdd hardware failure. In this case you should try to run a diagnostic tool to identify the exact problem of the failure.

SCSI Hard Drive Failure Messages:

• 096xxxx SCSI adapter with cache (32-bit) errors
• 112xxxx SCSI adapter (16-bit without cache) errors
• 113xxxx System board SCSI adapter (16-bit) errors
• 210xxxx SCSI fixed disk errors

Here's some background information explaining what causes such errors:

When your system is turned on, your computer BIOS performs a power-on self test (POST). It does this to verify that everything is working properly on your PC. When the BIOS boots your system to the point that it gains access to its video subsystem, it displays the information about the PC during the booting process. It uses the video system to communicate error messages like those above.

Different parts of your system can launch an error message, depending upon how far the booting process has progressed. Most error messages originate from the system BIOS because it is responsible for most of the functions for booting up. Still, other physical errors can be relayed to the Operating System. Those error messages are usually related to your Operating System.

One reason you receive such an error message is that the BIOS cannot find the drive, or one of the drives was not specified in the CMOS setup. Make sure that all the floppy boot drives have been removed from your system because this could be the cause for the error message.

If you experience this kind of disk error failure, you should be very careful about how you react because you could permanently lose important data. After determining that the problem is the result of a disk drive, try to run some diagnostic tools as was mentioned above or contact a professional data-recovery specialist.
