HP Z8 G4 Maintenance And Service Manual page 64

Can not write to the media card.
Cause
The media card is a read-only memory (ROM) card.
Media card is locked. Locking the media card is a safety feature that
prevents writing to and deleting from an SD/Memory Stick/PRO
card.
Unable to access data on the media card after inserting it into a slot.
Cause
The media card is not inserted properly, is inserted in the wrong
slot, or is not supported.
Do not know how to remove a media card correctly.
Cause
The computer's software is used to safely eject the card.
After installing the media card reader and booting to Windows, the reader and the inserted cards are not recognized by the computer.
Cause
The operating system needs time to recognize the device if
the reader was just installed into the computer and you are turning
the PC on for the first time.
After inserting a media card in the reader, the computer attempts to boot from the media card.
Cause
The inserted media card has boot capability.

Solution
Check the manufacturer's documentation included with your card to
see if it writable. Refer to the previous section for a list of
compatible cards.
If using an SD card, make sure that the lock tab located on the right
of the SD card is not in the locked position. If using a Memory
Stick/PRO card, make sure that the lock tab located on the bottom
of the Memory Stick/PRO card is not in the locked position.
Solution
Ensure that the card is inserted properly with the gold contact on
the correct side. The green LED will light if inserted properly.
Solution
Type file in the taskbar search box, and then select File Explorer
from the list of applications. In the left column, expand This PC,
right-click on the corresponding drive icon, and then select Eject.
Pull the card out of the slot.
NOTE: Never remove the card when the green LED is flashing
Solution
Wait a few seconds so that the operating system can recognize
the reader and the available ports, and then recognize the media
inserted in the reader.
Solution
1. If you do not want to boot from the media card, remove it
during boot or do not select the option to boot from
the inserted media card during the boot process.
2. During POST (Power On Self-Test), press
the boot menu.
3. Change the boot sequence in F10 Computer Setup.
