Also i can't even paste a file in the USB. How do I solve this problem

1) First step is to find the file's inode number:

- take a terminal, navigate to the directory where you have this file
- find the inode number using the below command:

# ls -il filename

- Suppose you get the output like this:

777777 -rw-r--r-- 1 jaysunn jaysunn 0 2008-01-27 11:19 corrupted_file

Then 777777 is the inode number.

2) Delete the file using the inode number using the below command:

find . -inum [inode-number] -exec rm -i {} \;

for example, to delete the file in my example, give this command:

find . -inum 777777 -exec rm -i {} \;

It may be that the USB is mounted read-only. In that case, even the instructions given by jaysunn will/should not work. Execute the command 'mount' to see what the USB drive mount permissions. If it is read-only, then you need to unmount and remount it for read/write. Also, some USB drives are actually flash readers and if the flash card (I use them all the time) has its write-protect slide set to read-only, then you will not be able to modify the data on the device, resulting in the I/O errors you are seeing.

hey how do I make the read only into read and write .

I had a similar problem few months back - Check this
http://www.linuxforums.org/forum/ins...ing-linux.html

I deleted some files but unable to delete few others....so i just re-formated the drive after copying important data from it.

I tried the link provided by lakshmipathi but it didn't work out for me. Here's the o/p
-----------------------------------------------------------------------------------------------------------------
[root@localhost ~]# mount -t vfat /dev/sdb1 /media/sdb1 -o defaults,umask=0
mount: mount point /media/sdb1 does not exist
[root@localhost ~]# mount -t vfat /dev/sdb1 /media/sdb1 -o defaults,umask=0
mount: mount point /media/sdb1 does not exist
[root@localhost ~]# cd /media/
[root@localhost media]# mkdir sdb1
[root@localhost media]# mount -t vfat /dev/sdb1 /media/sdb1 -o defaults,umask=0
[root@localhost media]# ls

[root@localhost media]# cd
[root@localhost ~]# cd -

d????????? ? ? ? ? ? ejb
[root@localhost sdb1]# rm -rf ejb
rm: cannot remove `ejb': Input/output error
[root@localhost sdb1]#

# ls -il filename

here's the op for u'r code pal
---------------------------------------------------------------------------------------
[root@localhost sdb1]# ls -il ejb
ls: cannot access ejb: Input/output error
[root@localhost sdb1]# ll

Unplug USB and plug it again. Execute this in Terminal :

tail -s 3 -f /var/log/messages

Post output here.
