2.6.2 ATA Cards
Once an ATA flash disk or hard-drive PC card is formatted (using the Disk Format /pccard command),
the card can be used the same as the on-board Flash disk. Files on the card can be references as “/pccard1/
directory/filename.”
Note: The SCS does not support PC card hot-swapping. Any time you insert a PC card
into an SCS PC card slot, you must reboot the SCS.
The Disk commands described above and on page 12-5 can also be used for file management on the flash
card. For example, to back up a Flash disk file (data.txt) to an ATA card, use the following commands to
create a backups folder on the card and to copy the desired file into that folder:
Figure 2-35: Backing Up Files To a Flash Card
The maximum number of files and directories (total sum) that can fit on the card is a function of the size of
the card: divide the size of the card by 5k (5120 bytes). This assumes that the average size of all the files
that will fill up the card will be smaller than 5k.
Data can be corrupted if power is lost in the middle of a write (for example, if the cord is pulled). If the Disk
Sync command is issued and power is removed after the command is completed, data will be stored
correctly on the card. Likewise, there should be no problems with data integrity if the Initialize Server
Delay 0 command is used to reboot the unit.
