pmpatrick Posted March 30, 2004 Report Share Posted March 30, 2004 (edited) The usb2.0 module is loaded but fstab looks to be a terrible mess. Make sure there is no zip disk in the drive and delete both of the zip entries as wll as this line: dev=/dev/scsi/host0/bus0/target0/lun0/part4,fs=ext2:vfat,--,umask=0,iocharset=iso8859-1,kudzu,codepage=850 0 0 Put this in their place assuming your zip disks are FAT32 formatted: /dev/sda4 /mnt/zip vfat umask=0,user,iocharset=iso8859-1,codepage=850,noauto,exec,quiet 0 0 Make a mounting icon on your desktop by right clicking on an open area and go to Create New>Device>Zip Device. A window will pop up for configuring the mounting icon. Click on the "Device" tab and tick the arrow next to the blank field and select /dev/sda4 then tick OK. Insert a zip disk in the drive and tick on your mounting icon. The drive should be automatically mounted and konqueror will come up displaying the contents of the disk. See if the transfer rates are any better. When done, close konqueror, right click on the mounting icon and select the "Unmount" option from the drop down menu.

william Posted March 30, 2004 Author Report Share Posted March 30, 2004 pmpatrick, thanks for your help, but unfortunately things didn't get better here. Despite of using enlightenemnt instead KDE, I succeeded in changing things in fstab through terminal. I deleted that those 2 lines (garbage and sda4) and inserted what you have suggested. Actually, that garbage line (recognizing my usb zip as a scsi ) appeared since I did an update in harddrake and afterwards, whenever I booted the computer the drakconf appeared suggesting that I new device was found and by mistake I should have accepted to write the "new" hardware in fstab. Going back to the point, after all the corrections in fstab, the problem seems to persist: [root@poseidon william]# hdparm -Tt /dev/sda /dev/sda: Timing buffer-cache reads: 1284 MB in 2.00 seconds = 640.50 MB/sec Timing buffered disk reads: 8 MB in 3.43 seconds = 2.33 MB/sec my fstab; [root@poseidon william]# cat /etc/fstab /dev/hda5 / ext3 noatime 1 1 none /dev/pts devpts mode=0620 0 0 none /mnt/cdrom supermount dev=/dev/hdc,fs=auto,ro,--,user,iocharset=iso8859-1,codepage=850,noauto,umask=0 0 0 none /mnt/flash supermount dev=/dev/sdb1,fs=ext2:vfat,--,iocharset=iso8859-1,kudzu,codepage=850 0 0 none /mnt/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,iocharset=iso8859-1,sync,codepage=850,umask=0 0 0 /dev/hda1 /mnt/windows ntfs nls=iso8859-1,ro,umask=0 0 0 none /proc proc defaults 0 0 /dev/hda3 swap swap defaults 0 0 /dev/sda4 /mnt/zip vfat umask=0,user,codepage=850,iocharset=iso8859-1,noauto,exec,quiet 0 0 Very strange, isn't it? That' s what makes Linux very exciting!!! Quote Link to comment Share on other sites More sharing options...
pmpatrick Posted March 30, 2004 Report Share Posted March 30, 2004 Just to see if it has any effect, try commenting out the /dev/sb1 line which I assume is your flash card reader. Having two mass storage devices on the usb bus might be causing some problems. Also, are you using the updated kernel? That has some usb fixes in it. I'm using the 2.6.3-7mdk updated kernel. You could also try a different usb port. Other than that, I'm fresh out of ideas. Quote Link to comment Share on other sites More sharing options...
william Posted March 31, 2004 Author Report Share Posted March 31, 2004 I installed yesterday the same kernel version you have, but the speed hasn't improved. Today I will comment out that line in the fstab and let you know if there was any success. thanks Quote Link to comment Share on other sites More sharing options...
aRTee Posted March 31, 2004 Report Share Posted March 31, 2004 (edited) Read my comment again. Read my review/website. This is a known issue. Mount the drive by hand (as root or with the correct line in your fstab as a user), you should get much better performance. If you don't understand what where or how, just ask - I've got some other stuff to do right now, will check back tomorrow.

william Posted March 31, 2004 Author Report Share Posted March 31, 2004 (edited) pmpatrick, I tried commenting the line for my flash card, but still no change in the speed. aRTee, I've already read and read and read your review, but what happens here is that whenever I delete the entry given by the system or edit it accordingly, as soon as I reboot the system, it insists in re-writing in the fstab the original entry. I've already checked if supermout was enabled in mcc (mount points session) and it was not. So, I think that I should be doing something wrong here.... Here, my fstab: [root@poseidon william]# cat /etc/fstab /dev/hda5 / ext3 noatime 1 1 none /dev/pts devpts mode=0620 0 0 none /mnt/cdrom supermount dev=/dev/hdc,fs=auto,ro,--,user,iocharset=iso8859-1,codepage=850,noauto,umask=0 0 0 #none /mnt/flash supermount dev=/dev/sdb1,fs=ext2:vfat,--,iocharset=iso8859-1,kudzu,codepage=850 0 0 none /mnt/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,iocharset=iso8859-1,sync,codepage=850,umask=0 0 0 /dev/hda1 /mnt/windows ntfs nls=iso8859-1,ro,umask=0 0 0 /dev/sda4 /mnt/zip auto iocharset=iso8859-15,codepage=850,kudzu 0 0 none /proc proc defaults 0 0 /dev/hda3 swap swap defaults 0 0 none /mnt/zip2 supermount dev=/dev/scsi/host0/bus0/target0/lun0/part4,fs=ext2:vfat,--,umask=0,iocharset=iso8859-1,kudzu,codepage=850 0 0 As you can see, the system is re-writing the "zip2" supermount and "dev/scsi" lines whenever I reboot the computer.

pmpatrick Posted March 31, 2004 Report Share Posted March 31, 2004 Try turning off harddrake in mcc>system>services. My theory is that your zip drive is being redetected by harddrake on boot and a new fstab entry is written for it. Then edit your fstab line and see if you get another fstab rewrite when you boot. If not, test with hdparm for any improvement. Quote Link to comment Share on other sites More sharing options...
william Posted March 31, 2004 Author Report Share Posted March 31, 2004 (edited) harddrake was already turned off, i had checked that before. edited: does hotplug have anything to do with that? Edited March 31, 2004 by william Quote Link to comment Share on other sites More sharing options...
pmpatrick Posted April 1, 2004 Report Share Posted April 1, 2004 My guess would be yes. But one way to find out; disable it and see if your fstab rewrites go away. Quote Link to comment Share on other sites More sharing options...
aRTee Posted April 1, 2004 Report Share Posted April 1, 2004 If you put a valid entry into the fstab, it should not try to make a new one. Deleting what is there then rebooting should create a new entry. Which did you do? Quote Link to comment Share on other sites More sharing options...
william Posted April 1, 2004 Author Report Share Posted April 1, 2004 I'm at work at this moment and: pmpatrick: I will check the hotplug aRTee: what I did was to put this entry here: /dev/sda4 /mnt/zip auto iocharset=iso8859-15,codepage=850,kudzu 0 0 none /proc proc defaults 0 0 and the system insists in writing this one: none /mnt/zip2 supermount dev=/dev/scsi/host0/bus0/target0/lun0/part4,fs=ext2:vfat,--,umask=0,iocharset=iso8859-1,kudzu,codepage=850 0 0 Note the iocharset is not the same in the entries, I've just copied what you put in your review, but I will change the first entry in order to make iocharset matchs what the system keeps writing. i.e.: iocharset=iso8859-1 instead iocharset=iso8859-15.

pmpatrick Posted April 1, 2004 Report Share Posted April 1, 2004 Delete this: /dev/sda4 /mnt/zip auto iocharset=iso8859-15,codepage=850,kudzu 0 0 and this: none /mnt/zip2 supermount dev=/dev/scsi/host0/bus0/target0/lun0/part4,fs=ext2:vfat,--,umask=0,iocharset=iso8859-1,kudzu,codepage=850 0 0 and insert this in their place: /dev/sda4 /mnt/zip vfat umask=0,user,codepage=850,iocharset=iso8859-1,noauto,exec,quiet 0 0 Your /dev/sda4 line is causing the problem because it has "kudzu" in it. That's for detecting new hardware IIRC. The line I gave you above should work. Afterwards, disable hotplug and reboot and see if fstab is rewritten. If not try hdparm test again. If there is improvement then try reenabling hotplug and see if fstab rewrites on reboot. If not, you can keep it enabled, otherwise disable hotplug and edit fstab again.

william Posted April 2, 2004 Author Report Share Posted April 2, 2004 (edited) pmpatrick, that's what I have in my fstab after copying and pasting what you suggested: /dev/hda5 / ext3 noatime 1 1 none /dev/pts devpts mode=0620 0 0 none /mnt/cdrom supermount dev=/dev/hdc,fs=auto,ro,--,user,iocharset=iso8859-1,codepage=850,noauto,umask=0 0 0 #none /mnt/flash supermount dev=/dev/sdb1,fs=ext2:vfat,--,iocharset=iso8859-1,kudzu,codepage=850 0 0 none /mnt/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,iocharset=iso8859-1,sync,codepage=850,umask=0 0 0 /dev/hda1 /mnt/windows ntfs nls=iso8859-1,ro,umask=0 0 0 /dev/hda3 swap swap defaults 0 0 /dev/sda4 /mnt/zip vfat umask=0,user,codepage=850,iocharset=iso8859-1,noauto,exec,quiet 0 0 none /mnt/zip2 supermount dev=/dev/scsi/host0/bus0/target0/lun0/part4,fs=ext2:vfat,--,umask=0,iocharset=iso8859-1,kudzu,codepage=850 0 0 . Unfortunately, It hasn't worked....during booting process the entry gets written again, despite hotplug is stopped. I've already spent a lot of time on it and so have you. I'll still have to put xmms to read my cd's, man. All the best, man! Edited April 2, 2004 by william Quote Link to comment Share on other sites More sharing options...
aRTee Posted April 2, 2004 Report Share Posted April 2, 2004 In that case, just use the device indication that supermount/kudzu/harddrake wants to create the fstab entry for: dev=/dev/scsi/host0/bus0/target0/lun0/part4 so instead of pmpatricks suggestion of this: /dev/sda4 /mnt/zip vfat umask=0,user,codepage=850,iocharset=iso8859-1,noauto,exec,quiet 0 0 try this: /dev/scsi/host0/bus0/target0/lun0/part4 /mnt/zip vfat umask=0,user,codepage=850,iocharset=iso8859-1,noauto,exec,quiet 0 0 Quote Link to comment Share on other sites More sharing options...
