3-16 Linux Setup and Operation
ACCESSING USB FDD
Access USB FDD after the device is mounted.
[How to mount]
# mount /media/floppy
TIPS:
If mount point is not automatically created, the service needs to be started again.
Run the following commands sequentially to start the service:
/etc/init.d/messagebus restart
/etc/init.d/haldaemon restart
Notes
When accessing USB FDD by directly specifying the sd device name as in the example
below, the device name may be changed if the system is disconnected or connected, and
the data on partitions of other disks may be corrupted unintentionally.
[Example]
When commands are run on USB FDD after connecting the system by using the same sd
device name as the one specified before it was disconnected, data on the partition of the
disk A may be corrupted.
How the sd device name changes:
Disk A USB FDD Disk B
Before disconnecting the system sda sdb sdc
After disconnecting the system none sda sdc
After connecting the system sdb sda sdc
1) Before disconnecting the system:
# tar cf /dev/sdb files

2) After connecting the system
# tar cf /dev/sdb files

CHECK:
It is a specification of the NEC Express5800/ft series to change the device name of the
device file when incorporating and disconnecting the system.
