• Bandlaufwerk versteht "End of Medium"-Anfragen: If No, the
archive device is not required to support end of medium ioctl
request, and the storage daemon will use the forward space file
function to find the end of the recorded data. If Yes, the archive
device must support the ioctl MTEOM call, which will position
the tape to the end of the recorded data. In addition, your SCSI
driver must keep track of the file number on the tape and report
it back correctly by the MTIOCGET ioctl. Note, some SCSI drivers
will correctly forward space to the end of the recorded data,
but they do not keep track of the file number. Default setting
for Hardware End of Medium is Yes. This function is used before
appending to a tape to ensure that no previously written data
is lost. We recommend if you have a non-standard or unusual
tape drive that you use the btape program to test your drive to
see whether or not it supports this function. All modern (after
1998) tape drives support this feature.
• Bandlaufwerk kann schnell vorspulen: If No, the archive device
is not required to support keeping track of the file number
(MTIOCGET ioctl) during forward space file. If Yes, the archive
device must support the ioctl MTFSF call, which virtually all
drivers support, but in addition, your SCSI driver must keep track
of the file number on the tape and report it back correctly by the
MTIOCGET ioctl. Note, some SCSI drivers will correctly forward
space, but they do not keep track of the file number or more
seriously, they do not report end of medium. Default setting for
Fast Forward Space File is Yes.

required to support keeping track of the file number and repor-
