Why has my HP v250W pendrive stopped working?

I bought HP v250w 16gb pendrive in may 2012. It has worked properly for couple of months.
Now I don’t know what has happened, my pendrive is not appearing in Ubuntu.
And in windows XP pendrive will be detected and the name will be “Removable Disk(J:)” instead of my name.
And when we click on that my files won’t appear but the message comes as “IT’S NOT FORMATTED. WOULD YOU LIKE IT TO FORMAT IT NOW? (Y/N)”. If I format, I will lose all my data.
Why this problem has come?
How to overcome it in future?
Is HP company not good?
Or it’s fault of mine?
This is second time it’s giving me this problem.
Please help me.

    in a terminal window run 'sudo tailf /var/log/messages' then attach stick: now lines should appear talking about USB. Run 'sudo lsusb': this shows all USB device chip set names the system has recognized. Run 'sudo fdisk -l': this shows you all hard disk(-like) devices and their partitions. Posting the USB lines from syslog and the chip set and partition information should help indicate what's up with the stick.

      Hi,
      These are the commands which I have tried and below are the responses from the terminal.

      iimsc@ibm40:~$ sudo tailf/var/log/messages
      sudo: unable to resolve host ibm40
      [sudo] password for iimsc:
      iimsc is not in the sudoers file. This incident will be reported.
      iimsc@ibm40:~$

      Now what should I do?
      Please help me.
      Thanks.

        try this
        sudo mkdir /media/usbdisk
        Now mount /dev/sdb to that folder.
        sudo mount /dev/sdb /media/usbdisk
        or
        sudo mount /dev/sdb -t vfat /media/stick

          it should be
          sudo mount /dev/sdb -t vfat /media/usbstick

          Hi,
          I have tried what you've said and these are the responses I got in the terminal. They are :-

          ibm01@ibm40:~$ sudo mkdir /media/usbdisk
          sudo: unable to resolve host ibm40
          mkdir: cannot create directory `/media/usbdisk': File exists
          ibm01@ibm40:~$ sudo mount /dev/sdb /media/usbdisk
          sudo: unable to resolve host ibm40
          mount: you must specify the filesystem type
          ibm01@ibm40:~$ sudo mount /dev/sdb -t vfat /media/stick
          sudo: unable to resolve host ibm40
          mount: mount point /media/stick does not exist

          It's telling that stick does not exist!
          What should I do?
          Please help me.
          Thank you.

        assuming usb key is FAT32; If it's ext3 than change "vfat" for "ext3"
        mkdir /mnt/usbdrive
        mount -t vfat /dev/sdb /mnt/usbdisk (if usb still /dev/sdb)
        cd /mnt/usbdisk

    The volume is corrupted. Maybe you plug it out when it was still working before. Try scanning it for errors. HP Pendrive is usually good, but you might get a faulty one.Try formatting it to see if the issue is resolved that way.

      Once I formatted it, and it worked properly for few weeks. Again the problem is back!
      That too, in so many systems it's not being detected (this problem is there from beginning) and even in my laptop, at only ONE port this device is detected and not on any three other ports.
      As per my knowledge, I was consious about removing the pendrive and I never gave it to others.
      Are there any other reasons for this problem?

        That's complicated.
        I thought your ports might be faulty (in my PC, only one prt can be used because the other one is broken) but you said it's not detected in another system too. And you're being very careful. Perhaps you bought a lemon...not much to do if it's actually problematic from the beginning.

    Try data recovery software such as Pandora Recovery or MiniTool Power Data Recovery Free Edition.
