How can I detect another Hard Disk in linux?

[tanmoy_rajguru2005]

Hi. I have attached another HD (in slave mode). Its NTFS file System with 5 partitions.one with windows xp installed with it. it was automatically detected by Xp. but with PCQ linux 2004 I cant find that HD. in my own HD one partition is NTFS. the linux is alright with it. so whats the problem with the other HD?

Check the output of fdisk -l . It's small L not big i.

su
fdisk -l

this is the out put

there you go. /dev/hdb is the other drive. Try

fdisk -l /dev/hdb

 

[tanmoy_rajguru2005]

ok I got it. but my problem how can I get the files like songs videos in the second hard disk and play them. in which folder thery are?

 

[mehulved]

Do this

su
mkdir /mnt/windows
gedit /etc/fstab

FIrst line will create folder named windows in /mnt/ folder. You can replace windows with any word of your liking. And instead of /mnt you can also use /media directory to create that folder
Second line will open up fstab file in gedit text editor. Replace gedit with kate in the command if you have kde running. Then add the following line

/dev/hdb  /mnt/windows   ntfs  defualts   0 0

Then give the following command

mount -a

Is your whole of 2nd hard drive as one ntfs partition?

 

[tanmoy_rajguru2005]

nope.
part of my second hard drive is FAT32

total list is here

[root@localhost root]# fdisk -l /dev/hdb

255 heads, 63 sectors/track, 9729 cylinders

/dev/hdb7 7542 9729 17575078+ b Win95 FAT32
[root@localhost root]#



and i am getting this after mount -a

[root@localhost root]# mount -a
mount: wrong fs type, bad option, bad superblock on /dev/hdb,
or too many mounted file systems
__________
after gedit /etc/fstab this i got the following and added the last line

LABEL=/ / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0

/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

yeah it wont work as you didn't give me proper partition layout.
Now replace hdb with hdb1
Similarly for hdb5 just change the dir name
For hdb2,6,7 replace ntfs with vfat
ntfs partition are read onlt by default. Install some software like ntfs-3g to enable writing to ntfs

 

[tanmoy_rajguru2005]

thank you. I made it for the first drive and then trying for the others. thnx again

BTW how can i unmount them all

 

[QwertyManiac]

Use the umount <mount_device> command. [Not unmount, but umount].

 

[gary4gar]

try

man umount

for mor details

 

[tanmoy_rajguru2005]

so for every new hardware (HD or CD writer) I attach I have to mount it before i can use it?

 

[mehulved]

Yes but if you have autofs, which I guess is there in many distros, then it will be automatically mounted, if it is detected.

 

[QwertyManiac]

Also you can create an entry under /etc/fstab which'll automount your specified devices on boot up automatically.
