My seagate 320 GB hard disk is not gettin detected

Hardware failure - the hard disk inside the case has died. Either replace the hard disk or buy a completely new unit.

i have one and what u need to do it open it the free agent cones with the software onit

It requires special hard ware tools to solve this problem. they are available with me and it just takes 20 minutes to get your data back. this is called LBA ZERO REPAIR, AND TRANSLATOR REGENERATION.

you have to FORMAT the hard drive you can only format a hard drive from another disk

Send your seagate back under warranty (RMA) they will send you a new one.

Download testdisk and run it to see if it recognised in the list. If so use the intel option to find a boot sector

You need to set one of the drives to be 'master' and the other to be 'slave'.
This is done by positioning jumpers on the back of the harddrives.
Pretty sure that on the drives is explained somewhere how to position the jumper, for several options.

Good luck,
Please post some feedback.

When your hard disk capacity says 320, that does not mean 320 GB fo free space, Total capacity is 320 GB, from this space required for the partition table, boot sector, etc will be taken, Dont worry only the available free space will be shown.

This is not a problem, so dont worry.
