This is the first of three sections that describe how to format and copy files from a PCMCIA memory card to a hard disk or from a hard disk to a PCMCIA memory card.
See the man pages for further information on how to use the cpio or the dump/restore commands.
This section describes the following tasks:
Formatting a PCMCIA Memory Card
Displaying file names
Copying files
Before you can use a PCMCIA memory card, you may need to format it. The fdformat utility allows you to format both diskettes and PCMCIA memory cards.
Formatting deletes any data that may already be resident on a PCMCIA memory card.
To format a PCMCIA memory card:
Type:
% fdformat option device_name |
The format utility cannot be used with PCMCIA memory cards. Only the fdformat utility will work.
Table G-1 lists the available options for the fdformat utility.
Table G-1 fdformat Utility Options
Option |
Description |
---|---|
Unmounts the PCMCIA memory card |
|
Installs an MS-DOS file system (UNIX file system is the default) |
|
Does not display confirmation messages before starting to format |
|
Disables print status messages |
|
Installs a Solaris label or an MS-DOS file system; it does not format the PCMCIA memory card |
|
Specifies a UNIX or MS-DOS label on a PCMCIA memory card |
|
Installs an MS-DOS file system (UNIX file system is the default) |
|
Installs a special boot loader |
There is no option in the fdformat utility for installing a NEC-DOS file system on a PCMCIA memory card.
If you want to format a PCMCIA memory card, you must specify a device name for the PCMCIA memory card. Otherwise, the fdformat utility automatically specifies the diskette drive as the default device.
The format for a device name of a PCMCIA memory card is
/dev/rdsk/cntndnsn
or
/dev/dsk/cntndnsn.
For example, the device name /dev/dsk/c1t6d0s2
represents a PCMCIA SRAM memory card with a logical socket controller
number 1, a technology number 6, and
a slice number 2.
Table G-2 list the available device name options for the fdformat utility.
Table G-2 fdformat Utility Device Name Options
You may want to display the file names that are resident on a PCMCIA memory card.
Table G-3 tar Command Options to Display Filenames
Option |
Description |
---|---|
-t |
lists or displays files that are resident on the PCMCIA memory card |
-v |
specifies a verbose listing |
-f |
To copy a file or directory from a PCMCIA memory card to a hard disk or from a hard disk to a PCMCIA memory card, you must have already formatted the PCMCIA memory card (see "G.3.1 Formatting a PCMCIA Memory Card"). In addition, you must have write permission for the destination directory on the hard disk.
If you use the following procedure to copy a file or directory, you preserve the owner, permissions, group, and modification time of the file or directory.
If you use the tar command to copy files to a PCMCIA memory card, you must use the tar command to extract or copy files from the PCMCIA memory card.
Type:
% cd directory |
where directory is the name of the directory in which the files that you want to copy are located.
For example, to copy the file /home/samples/design, type:
% cd /home/samples |
Type:
% tar cvf device_name filename |
Table G-4 tar Command Options to Copy Files to a PCMCIA Memory Card
Option |
Description |
---|---|
creates a backup archive |
|
displays a verbose listing |
|
specifies an input device name |
For example, to copy the file ./design located
on your hard disk to a PCMCIA memory card that has the device name /dev/rdsk/c1t6d0s2
, type:
% tar cvf /dev/rdsk/c1t6d0s2 ./design |
Type:
% cd directory |
where directory is the name of the directory in which the files that you want to copy are located. In this case, the directory is located on the PCMCIA memory card.
For example, to copy the file /home/samples/design, type:
% cd /home/samples |
Type:
% tar xvfp device_name filename |
Table G-5 tar Command Options to Copy Files from a PCMCIA Memory Card
Option |
Description |
---|---|
extracts a backup archive |
|
displays a verbose listing |
|
specifies an input device name |
|
preserves the original modes of the file |
If a file or directory with the same name as the one being copied already exists in the working directory, it is automatically overwritten.
For example, to copy the file ./design from a PCMCIA
memory card with an address /dev/rdsk/c1t6d0s2
to the working directory on your hard disk, type:
% tar xvfp /dev/rdsk/c1t6d0s2 ./design |
