      well hard disk can be dead

      1)Ensure that the drive is plugged in and the cables are not backwards
      2)Reset COS battery, configure CMOS

      3)Go into your BIOS and ensure that Autodetect is set for the I/O port the drive is on, or use the IDE hard drive detection utility.
      4)Check if your SATA controller is enabled in BIOS, turning on and off SATA in the bios
      5)update your BIOS
      6)

    When I followed the suggestion given by ha14, I found that the regular internal hard disk that is formatted as C: D: E: and F: is shown as Disk 0 and the External Disk is shown as Disk1. It does not show any identification letter etc. and the space is shown as unallocated. However, right now with the Windows XP that I have and with my limited skills, I am unable to find the right software for formatting or creating a partition that Fidelis has suggested. However, with this information, I am now reasonably confident that the disk can be retrieved by giving it to a service engineer. I was thinking that the Disk has gone kaput. I thank the friends who gave the valuable suggestions. Regards.

    Hello, create one partition on the drive by using disk management.  In the same box that pops up, make sure to give it a letter and choose NTFS.  You can also give it a name.  If after trying the suggestions it fails to show, you could try using the seagate tools to check your drive:

    Actually, the problem started after it got formatted by mistake - the loss of data itself is not a big problem (nothing really critical was there on it), but now the PC says the hard disk is working but the location is not coming up. Thanks for the suggestions - I will try them and get back to you. Regards.

    It may not be formatted - one helpful thing is to download the hard drive utility from whoever made the actual drive - these are free and can be a huge help.

    I would check under disk management in computer management to see if the drive is listed. It should be listed there

      This is exactly what ha14 is getting at.
