Toshiba e-Studio 2010AC

Overview

This mode enables you to operate the HDD partition, formatting SRAM data, delete the HDD/SRAM data and backup/restore the encryption key and license.

Operation procedure

1. Perform [HS-73] by pressing [73 Firmware Assist].
2. Press the icon to operate.

Functions

[A] Clearing update error flag (Clear Software Update Error Flag)

Even if the firmware downloading has been completed normally, the Recovery Mode may accidentally start up and an F600 error occurs when the power is turned ON again. In this case, clear the Update Error flags used in the download process with this function. (Normally, the flags are automatically cleared in the download process.) Also in the case the Recovery Mode accidentally starts up after the replacement of SRAM, the flags are cleared with this function.

[B] Formatting data storage partition (Format Root Partition)

When a defect occurs on the UI data, etc. which are stored in the HDD, the partition with the stored UI data, etc. is formatted with this function. Do not use this function since it is not normally necessary. HDD data must be installed after performing this function.

[C] Creating HDD partition (Format HDD)

When the HDD is replaced or UI data, etc. are downloaded using the USB storage, it is necessary to format a partition in the HDD before downloading. In this case, the partition is created in the HDD with this function.

Notes:

• Perform the HDD partition formatting only when a new HDD is installed since all data in the current HDD are erased by this operation.
• When this operation has been done, do not perform SRAM data formatting (Clear SRAM) before the normal start-up.

[D] Backing up/restoring encryption key and license (Key Backup Restore)

When the SRAM or the SYS board is replaced or initialized, the encryption key and license are erased. Therefore, they need to be backed up or restored with this function.

[E] Erasing HDD securely (Erase HDD Securely)

This function is used when installing Data Overwrite Enabler (GP-1070) or before discarding the HDD. It overwrites all the used areas on the HDD with the selected data, and makes it unusable. After selecting this function, specify the level below to be overwritten. This setting is the overwriting method complying with DoD 5220.22-M.

• LOW (Normally use this setting.) This is the standard overwriting method. “00-FF-Random-Verify” Once
• MEDIUM This overwriting method is more secure than LOW. The erasing time is between LOW and HIGH. “00-FF-Random” three times repeatedly -Verify
• HIGH This is the most secure overwriting method. It takes the longest time to erase data. “00-FF-Random” five times repeatedly -Verify
• SIMPLE This is the simple overwriting method. It takes the shortest time to erase data. Overwrite the Random data onc

The reconfirmation screen is displayed when the icon is pressed. Press [OK]: Processing starts. Press [Back]: The screen returns to the previous one.
Notes: When this operation has been done, do not perform SRAM data formatting (Clear SRAM) before the normal start-up.

[F] Formatting SRAM data (Clear SRAM)

When SRAM is replaced with a new one, abnormal values may be written in the new SRAM. SRAM data must be formatted with this function for such case.

Notes:

• This function is required only when a new SRAM is installed.
• Do not perform this function in cases other than the installation of a new SRAM because all data in the SRAM will be deleted with this function.
• When this operation has been done, do not perform HDD partition creation (Format HDD) before the normal start-up.

[G] Erasing SRAM securely (Erase SRAM Securely)

This function is used before discarding the SRAM. It overwrites all the used areas on the SRAM with the selected data, and makes it unusable. Immediately after selecting this function, the processing starts and is completed.

[H] Clearing service password (Clear Service Tech Password)

This function is needed after the HDD is replaced. When the HDD is replaced, the service password stored in the new one is set as a blank. Therefore, its service password is copied to the SRAM so that both passwords become the same with this function. The setting is enabled when the equipment is started up in the normal mode after performing this function.

[I] Disable Fast boot

This function disables faster start (*). Therefore, this can be operated while faster start is enabled.

* Faster start: The start-up method which can shorten the time for starting by approx. 5 seconds by starting up the equipment in the normal mode or while selecting the menu from the exclusive file. (There is no effect on the recovery from hibernation.)

Once the power is turned ON while the [HOME], [RESET] and [START] buttons are pressed simultaneously, a file for faster start is created and it becomes available. It will take approx. 3 minutes to create a file for faster start. When the file creation is completed, the equipment will automatically start in the normal mode.

Faster start can also be disabled by the following operations.

• Firmware update
• HS-73 → [Format HDD]
• Data Overwrite Enabler (GP-1070) installation or settings change
• Security level change
• HS-75 → [Initialize HDD]
• HS-59 → [Restore SRAM Data from USB]

[I-1] Restoring HDD Data (HDD Data Restore)

This function performs formatting, backup data restoring and firmware upgrading in series.

Notes:

• Perform this function only after the HDD is replaced or when there will be no problem even if all the information in the HDD is erased.
• Perform this function only when a USB storage device (*), in which the backup data and the firmware standard package are stored, is prepared. * It is available even if these 2 files are stored in different USB storage devices separately.

1. Install the USB storage device with the backup data stored in the equipment.
2. Perform this function.
   • Format the HDD and restore the backup data.
   • If the firmware standard package is stored in this USB storage device, continuously upgrade the firmware.
   • If the firmware standard package is not stored in this USB storage device, an error appears. In such a case, install the USB storage device with the firmware standard package stored in the equipment and press [OK]. Firmware upgrading will start.
   • After upgrading is completed, reboot the equipment.
