Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am new to this site and to linux... I have a cipher M990 tape Drive, and had wanted to get it working on Windows, for experimentating with and to read old tapes, that I have... I was directed to Use Linux instead, and have had some good response from the drive... I don't have the MT command on my system, it is a Fedora but I don't know which version.. I am writing the post on a different machine (Laptop) than the one I have the tape connected to. I have it connected as an SCSI and not as Pertec, and when I try to mount the tape the tape moves and re-looks for BOT... but it won't mount it says it needs filetype.. I hope to get MT coppied from this machine to the other machine by jump drive as soon as I can find it on google.. so I can try out the different commands like erease, rewind, etc....
THANK YOU marty
Welcome to LinuxQuestions.
I agree it would be much easier on a linux vs windows PC.
It has been a number of years since I have played with a 9 track tape drive. Those were the days...
Never played with one on a linux computer.
You can install mt via yum. Try yum install mt-st (as root). If your version is no longer supported this will fail.
Tape drives are not mounted like a file system, instead they are read like a data stream (character vs block device) and can be opened like a file.
If the controller recognized the drive and all the modules are loaded you should have a /dev/st0 and /dev/nst0. The difference between st0 and nst0 is that nst0 will not automatically rewind the tape upon completion of a command.
Do you have any idea on what or how the tapes were created? You might want to start by reading a few bytes from the tape via the dd command.
dd if=/dev/st0 of=/some/where/test.dat count=1 bs=1024 (Change the count to read as many blocks as desired)
Thank you for your response..
I had Fedora ver 9, and I have today upgraded to Fedora 12, I didn't know about setting the Mt with yum so I will need to try and do so as I am not able to get permission to do anything with mt...
also , how do I get the # instead of the $ on terminal mode ??
THANK YOU Marty
Thank You for your help..
I got the tape to move and obey commands. I have upgraded to Fedora 14, since I thogh the problem was with fedora 12... Which it wasn't...
I would like to read a tape which is at 1600 bpi and see if it is or was , my other tape, since I was using a scratch tape, I don't know of its quality.. I have tried to use tar but it says it can't open the directory i had already created, which is at --- /home/marty/tape ...
So how do I get tar or some other program to read this tape ????? It may be characters or binary.. is is for a backup for a Nova MV compuer using Pcopy, so I think I should be able to read it.. I have lots of other tapes for various old computer systems, but most of them are at 65xx bpi.. and I have not tried to read them yet, as a 1600 bpi i am working on first...
THANK YOU Marty
I have run the tar programs and get the following error -- cannot read --Input/output error. ----
I have run the Diagnostics on the drive itself.
Does anyone have a manual or switch settings for the scsi interface -- cipher csc 100 ????????
THANK YOU Marty
I GOT it to work !!!!! I found out I had to write to the tape since I was using a blank scratch tape. so after many tries and attempts, not knowing what I was doing I got it to write to the tape and then tell and all the other commands work... SO THANK YOU !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
now HOW do I make directories and copy "test" files (text) and del these files as needed... I have copied the GPL liscence file to the tape as a test, but instead of typing /home/Marty/Downloads/GPL , I would like to create a directory /marty and copy the GPL text to that shorter location (less typing) but I go and do a gui copy but it won't let me create a directory /marty , nor copy to it ????????
THANK YOU Marty
Yes, that will get the file copied to the tape, and that is what I would like to do... but, I need to copy the file from home/Marty/Downloads/GPL to home/marty.. and I can't get it to do that.. before I copy it to tape I need a file to copy... but on another vein I am going to try to copy an unknown tape to that file and see what happens... So, THANK YOU.. I found out that cp is the copy program that I want, and it did what I needed to get done.. I have copied to tape with both Tar and Dd , so I now know that the tape drive works... and copied them to a different place on the drive..
I now need to delete files , I know how to delete directories, but not individual files... I also now know that I will need special software to read these old tapes that I have, I have a friend who has this software (He wrote it) to do just this... So for now I have done all I can with my old tapes... I will keep on experimenting with my tape drive and reading and writing.... THANK YOU
