We are equipped to deal with firmware problems like:
1)The BIOS detects the hard disk but reports an unusual model # or disk capacity. The operating system cannot access the data.
2)The BIOS detects the disk but reports 'SMART Status: Bad' backup data and replace hard disk immediately or a similar message. Or 'Primary HD failure, press F1 to resume'.
What happens if you have a hard disk which spins erratically, or the heads are making clicking noises, or maybe everything seems fine but the disk is just not recognized by the PC or any other tool? Since you don't have access to the disk you may conclude that it is due to the controller board failure or some mechanical or physical damage, and whatever you try to do to fix the drive is then driven simply by your intuition because you have no information about the status of a drive that is simply not recognized by your utilities.
But help is at hand, we usePC-3000 UDMA , a unique tool that can communicate with the drive in such situations by using vendor specific commands to switch the drive into kernel mode - the one that is used by the manufacturer to provide read/write access to the firmware on the controller board and firmware modules, such as Microcode Overlays, HDD Configuration Tables, Defects Tables, SMART Attributes, Security Subsystem, Adaptives, etc., stored at the disk system area (maintenance track) at negative cylinders. When the drive is not recognized by the PC, it basically means that the HDD cannot boot up properly due to electrical failure, mechanical/physical damage or corruption of the firmware modules on the controller or the disk system area (maintenance track)
By using PC-3000 UDMA drive can be diagnosed and can be determined exactly what is causing the failure. Furthermore, in our experience more than 50% of such failures (and for some particular HDD models over 90%) are due to firmware related problems that can be resolved using PC-3000 UDMA.
