Hello,
i have a linux machine. After installation it in not reading pen drive and cd drive. After some googling for pen drive i tried this as follows:

[root@arnab]# dmesg | tail -100

The output is as follows,

my /etc/fstab file is as follows:


/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
/dev/sdd /mnt/pen auto user,noauto,rw 0 1



i can now mount my pen drive by,
mount /dev/sdd1 /mnt/pen/
but only after using this command i can see a disk photo comes in desktop as pen drive. Each and every time i need to use this command to access the pen drive. Why it is not auto detected by the machine? Also for cd drive i am in still dark. please help me out




Thanks in advance

Depending on the version of KDE and file manager you are using, there is a simpler route to accessing drives (if they are not being automounted). In Konqueror there is a panel on the right side, a thin panel that is further to the right than the folder panel. The last button on that panel, labelled system, is useful. Click it and you will find an entry called Storage devices, which you can select and refresh (F5) and you will see all newly plugged storage devices. Double click any and they will be accessible, under media. KDE4 the dumbest desktop manager ever has castrated Konqueror in many respects, and even added an even impotent dolphin for this job, so all the above applies to Konq used in KDE3.5 or less.

More technically, automounting is controlled by the autofs service, which is probably disabled. Check for the services that are started at boot time by visiting the control panel (it is there somewhere).
