VERY annoying Floppy problem in Slackware... :-/

MuD · 02-26-2005, 02:43 PM

My dad wants to access his Floppy with some important files on it (files made on Winbloze - where he works they're still using that crap). So anyway, I mount the floppy for him, and everything goes smooth. The PC can read the Word files and opens them in OO.o. No problems so far. But when we try to save the changes to the file, Slackware spits out an error message. "General Input/Output Error". WTF?! I know the Matrix isn't real, but that's scary...

This is what is included in /etc/fstab:

Code:

/dev/hda5        swap             swap        defaults         0   0
/dev/hda2        /                reiserfs    defaults         1   1
/dev/cdrom       /mnt/cdrom       iso9660     noauto,user      0   0
/dev/fd0         /mnt/floppy      auto        noauto,user      0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0

The only way we can save the file on the Floppy is to save it on the PC first, then copy that file back to the Floppy (we can't erase or overwrite the old file on the Floppy) as Root. Anyone know what the problem could be? Because I can't figure it out and I'm still a...

Modify the config to be

Code:

/dev/fd0         /mnt/floppy      auto        noauto,user,umask=0      0   0

It's permission problem. This should allow other users to write the floppy.

Thanks Mara! That did the trick!

On a related note, Slackware detects my current CD-RW/DVD-ROM but I couldn't find a way to mount it. Someone suggested that I should type in Konsole:

# mkdir /mnt/hdd (create the mount point)
# mount /dev/hdd /mnt/hdd

So I did that, but now when I insert a blank CD-RW, it says:

"Error Kio_devices_mounthelper"

Code:

mount: block device /dev/hdd is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdd,
missing codepage or other error
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
In some cases useful info is found in syslog - try
dmesg | tail or so
Please check that the disk is entered correctly.

The /etc/fstab file is as follows:

/dev/hda5 swap swap defaults 0 0
/dev/hda2 / reiserfs defaults 1 1
/dev/hdd /mnt/hdd iso9660 noauto,user 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,user 0 0
/dev/fd0 /mnt/floppy auto noauto,user,umask=0 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

The emphasis (bold) is what I added for the CD-RW/DVD-ROM to be recognized. Any idea what could be missing/wrong?

You can't mount blank media or audio CDs. To write to a CD, either use a GUI like K3B, or use the CLI 'cdrecord' or 'mkisofs' (K3B is just a front end for these anyway)

MuD · 02-26-2005, 06:58 PM

Oh I see, so I should just insert the blank CD-RW, start K3B and burn away? If so, then that's cool.

MuD · 02-27-2005, 09:35 AM

Now I installed K3B, but when I started the program this is what I get:

Code:

Unable to find cdrecord executable
K3b uses cdrecord to actually write CDs.
Solution: Install the cdrtools package which contains cdrecord.
Unable to find cdrdao executable
K3b uses cdrdao to actually write CDs.
Solution: Install the cdrdao package.

WTH does that mean?

DaHammer · 02-27-2005, 01:52 PM

Exactly what it says. Install cdrecord and cdrdao.

MuD · 02-27-2005, 04:38 PM

Uhm, I'm on Slackware...any idea where I can find "cdrecord" and "cdrdao"?

Tino27 · 02-27-2005, 04:42 PM

DaHammer · 02-27-2005, 05:31 PM

On the CD, they are both in the ap directory:

slackware/ap/cdrdao-1.1.9-i486-1.tgz
slackware/ap/cdrtools-2.01-i486-1.tgz

You can find a complete list of all available packages that come with Slackware in the PACKAGES.TXT file. You can also find a complete list of every file on a complete slackware system in the slackware/MANIFEST.bz2 file.

MuD · 02-27-2005, 05:39 PM

Thanks, I've got them installed.

But now I've got another problem...

Code:

cdrecord does not run with root privileges
It is highly recommended to configure cdrecord to run with root privileges. Only then cdrecord runs with high priority which increases the overall stability of the burning process. Apart from that it allows changing the size of the used burning buffer. A lot of user problems could be solved this way. This is also true when using SuSE's resmgr.
Solution: Use K3bSetup to solve this problem.
cdrdao does not run with root privileges
It is highly recommended to configure cdrdao to run with root privileges to increase the overall stability of the burning process.
Solution: Use K3bSetup to solve this problem.

So I started the K3bSetup, but I don't know how to change the permission. This is what I get:

Anyone know how to change the permission?

Tino27 · 02-28-2005, 07:33 AM

Click "OK".

MuD · 02-28-2005, 05:48 PM

I did that, but now when I try to burn data on a blank CD-RW, it says:

Code:

K3b did not find a suitable writer.
You will only be able to create an image.

It's one problem after another... sigh...

Tino27 · 02-28-2005, 07:05 PM

Since we're both running Slack 10.1, I feel it okay to share this bit of info with you. I checked out the permissions of the various devices in the previous screenshot you linked to. The cdrdao and cdrecord permissions were identical to mine. The devices, however, differed slightly. On my system (which I have only a CD-RW hanging off /dev/hdb) the permission were of the following:

/dev/hdb is owned by root.cdrom, not root.disk. Also, the permissions on /dev/hdb are rw / rw / none for owner / group / others. Your devices were marked 666 with means rw for everyone. If it were me, and the standard disclaimer applies here, I would try reassigning the owner of one of the drives to root:cdrom using the "chown" command (you'll have to be root to do this). If this fixes the problem, then change the other one as well. If it doesn't fix the problem (or it makes it worse), just change the owner back to root:disk.

Hey Tino27,

Thank you sooo much for your help. I can finally burn CD's again! Woohoo! This O.S. is kick-ass!!!

All I had to do was login as root, go to Devices (in Konqueror) and right-click on the CD-RW icon. There I just set the permission so that "others" could read/write too. That's it! I'm a happy camper. Thanks again for your invaluable help.
