Show current disk status



If you select "Show current disk status", the following screen will be displayed.

List of connected disks

The model number, capacity, firmware revision, and disk serial number of the disk recognized by the "Green Pepper PRO" system are listed.
* For a single disk, it is a physical disk unit, and for a RAID configuration, it is a logical disk unit.
* For RAID disk or others, revision, and serial number may not be displayed.

As shown below, if the message "NO supported disk" is displayed even though the disk is connected, the disk is not recognized.
* There may be a disk failure.

        
MEMO  ***  If the disk does not appear in the list
Check the disk hardware
・ First, check that the disk is recognized on the BIOS screen of the PC.
To display the BIOS screen, see "Setting the boot environment on BIOS/UEFI". Information about the disk is displayed in this screen.
・ If Windows works, make sure that Windows recognizes the disk.

Check if it is supported by "Green Pepper PRO"
・ If the interface is not supported by "Green Pepper PRO", the disk will not be displayed.
・ Please let us know the contents of "Disk Interface" displayed in "Show current disk status"

* You can save the screen image to the FD / USB flash drive /Net share with "Utility" / "Save screenshot (FD / USBmem/Net)" displayed by ALT + F5.
Or
* Use "Write hardware information to FD / USBmem / Net" in "Utility" displayed by ALT + F5, save the PC information to USB flash drive / FD, and send the file (HWINFO.TXT) to us.
   
MEMO
The beginning of the line is
[1] (parentheses) are ATA (IDE, SATA) disks.
<3> (parentheses) are SAS / SCSI / RAID connections.

 ! 1 xxxxxxxx
Those with "!" Displayed are IDE disk interfaces that do not support high-speed mode (DMA) in the hardware / driver.
The access is low-speed mode (PIO mode), and the processing speed is very slow.
   
MEMO - about eMMC drive
On eMMC drives, you will often see multiple drives as shown below.
This is because one eMMC drive is divided into multiple drives.
Among them, (boot0) (boot1) is the boot partition. (rpmb) is a security partition called "Replay Protected Memory Block". Both are normally not writable and cannot be erased.
  

Detailed information of the disk

Select the disk using the [up] and [down] keys in the list, and press [enter].
Detailed information about the disk is displayed as shown below.

Display for ATA (IDE, SATA), SCSI, SAS, etc.
-----------------------------------------------------------------------------------------------------------


* The following information is available only if it can be obtained. The correct value will not be displayed on disks and interfaces that do not support data acquisition.

HDD/SSD,Flash
For hard disks, "[HDD]" is displayed, and for Flash drive/ SSDs, etc., "[SSD, Flash]" is displayed.
If it is not sure, "[HDD/SSD]" will be displayed.

Current Size

The currently accessible disk size is displayed in terms of the number of sectors.
This number of sectors x 512 bytes (logical sector size) is the disk capacity (bytes).

PowerOnHours, PowerCycl

Shows how long the disk has been used and how many times it has been turned on.

Reallocated Sectors
Displays the number of sectors that have been detached and reallocated.
1 sector = 512 bytes. The area of detached sector x 512 bytes is inaccessible.
This number is used to indicate how damaged the disk is and to determine the need for "Secure erase/Sanitize".
See "About Secure Erase/Sanitize","Points to consider about erasing method".

Physical Sector
Shows the physical sector size of the disk. Usually 512 or 4096.

W/C
Shows the status of Write Cache. [1]:ON, [0]:OFF. [-]not supported or undefined.
* Supports ATA(SATA,IDE) drives or SCSI (SAS) drives connected by compatible interfaces which does not have RAID function.

HPA/DCO(x512byte)
ATHPA and DCO is a standard for ATA disks that allows access only to the limited area.
Displays the disk size limitation status by HPA (Host Protected Area) and DCO (Device Configuration Overlay).
See "Points to consider about erasing method".

HPA disabled HPA is not set.
HPA enabled
HPA:All Sectors[xxxx]  
HPA is set. The total disk capacity is [xxxx] x512 bytes.
* Currently accessible area is the above "Current size".
HPA Unknown: error to get size Cannot get the correct HPA information.
HPA Unsupported A disk that does not support HPA.

DCO disabled DCO is not set.
DCO enabled
DCO:All Sectors[xxxx]  
DCO is set. The total disk capacity is [xxxx] x512 bytes.
* Currently accessible area is the above "Current size".
DCO Unknown: error to get size Cannot get the correct DCO information.
DCO Unsupported A disk that does not support DCO.
* The DCO setting is a higher level limit, and the HPA is set internally when the DCO is set.
* The total capacity displayed in the DCO settings is the total physical capacity of the disk.
