User preferences can be configured by selecting "Preferences..." from the "Edit" menu. The following preferences can be configured:
This value will be used as the default tape size when formatting a tape.
The hardware block size for the tape drive. For floppy tape drives this value should be 10240 bytes.
The full path to your tape device (usually /dev/tape). This path must point to the non-rewind version of you tape device.
The full path to the tar command on your system.
If enabled, before trying to mount a tape KDat will issue an "mt load" command to the tape drive. Some drives may require this before reading and writing the tape.
If enabled, whenever a tape is mounted by KDat, the tape drive will be asked to disable the eject button. This option may not work with all tape drives.
If enabled, whenever a tape is unmounted by KDat, the tape will automatically be ejected from the drive. Do not use this option with floppy tape drives.
If enabled, KDat will attempt to change the hardware block size used by the tape drive. Not all drives support variable block size. Whether this feature is enabled or not, you must tell KDat the block size that your tape drive uses (i.e. 10240 for ftape users).
