3.2.6 Action be taken when the hard disk crashes
The followings describe an action to be taken when the hard disk crashes at the customer site.
3.2.6.1 Crash of HDD
Crash of HDD is divided into the following two cases:
1) Hardware crash: Ultrasound scanner does not start up because the HDD cannot be driven
due to degradation of HDD hardware.
2) Software crash: The ultrasound scanner does not start because some file written in HDD
is broken.
These two crashes may not be simply identified. Incase of HDD crash, take the action for
hardware crash.
In either case, the action initializes user setting information. To prevent this initialization,
it is helpful to use "Backup data" of "Main Menu" to backup user setting information
periodically. By restoring this backup to the equipment after taking the action, user setting
information can be protected (Refer to 3.2.3 and 3.2.4 for details).
The action to be taken in the two cases mentioned above will be described in the following
subsections.
3.2.6.2 Preparation before the action
Prepare the following media supplemented to EUB-5500.
1) EUB-5500 System CD (CD-R)
Needs to start Recovery Medium and includes HDD recovery tools. Also, directly it can
run the ultrasound scanner in place of HDD. Hereafter described as CD-R.
2) EUB-5500 Authentic Disk (FD)
Required when the system is provided with any onerous option.
Required for releasing protection of onerous optional functions.
Hereafter described as A-Disk.
A set of these media is supplemented to a system and exclusive to it. If these media
supplemented to the system for which an action is to be taken cannot be prepared, stop HDD
recovery.
NOTE: If using any media of the other system, the unauthorized copy protection function
makes the media unusable after that.
