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

ÆFiles are written in USB FDD.

2)After connecting the system

#tar cf /dev/sdb files

Files are written into the disk A unintentionally Æ Partitions are corrupted

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.
