About 6 months ago my laptop stoped detecting the hard disk. So thinking that the disk was faulty I brought a new disk, but not from the same brand or size. The laptop is an IBM thinkpad 310ed and the disk was 2.1 gb in size. The disk I brought was a western digital 10 GB disk. The guy in the store sayed it didnt matter and that all disks were compatible. However my laptops disk came in a cover with a connector that was connected to the pins, and the guy at the store adapted the cover and the connector to the new disk. I put the new disk in the laptop and tried to fdisk and I got a message saying that there was no fixed disk. I also went to the bios and the disk was not detected. So I thought that the disk might have not been adapted correctly to the cover and to the conector so is there a link were I can see pictures of how to to properly install the hard disk?
