I have a Hitachi 1Tb hdd and when I plug it into my Hp laptop for windows 8 it doesn t show up. Before it was working fine and I don t have that much data on there. Yesterday, before it stopped showing up completely on my computer it said cyclic redundancy check error. I looked some solutions and figured I try to do it today, however its just not even being recognized. The power is on and I hear it running whenever I plug it up and its getting frustrating. Plz help.

Have you tried this drive with another computer. Also, Plug the drive in and restart your computer, now, Press DEL, F2 or F10 to boot into the BIOS (( The key for booting into the BIOS will vary according to your Computer )). Locate the information section and locate the hard disk drive information. Check if your External Hard disk is listed there. if its listed there, it means that your hard disk is ok and there is some problem with Windows.

After reading all the issues I do not have a very good feeling after buying this new laptop with windows 8 on it. I want to get some information off the old hard drive and want to know what adaptor to buy, but from the sound of it, nothing is going to work. I need some way to get the information off the OLD hard drive and onto the NEW computer, has windows 8 made this impossible? It not what cables should I buy?

I feel like I have been dooped buying this computer with windows 8 on it.
Please help.

It depends on what type of Hard disk your old computer was using. Is your old computer a desktop or a laptop. The best way is to take it to a computer store and buy an external enclosure for it.

Remember two things :
1. is it a 2.5 or 3.5 drive ?
2. Sata or IDE ?

Hi, i have problem with my external hard disk. This is the thing. When i try to copy files on Hard disk everything is normall, but when i try to get them back, they will not be copied. I tried to copy on another pc, its all the same. But there is one catch, when I put to copy smaller files up to 400 MB then all works. Im confused, obviously my hard is working, but i dont understand why cant copy big files, like more then 400 Mb, can you help me with this?

Hi, I think this is related to the file system. somehow your file system is following the older Fat file system architecture. Can u confirm that you are using NTFS file system. Also share the capacity / make and model of your drive.

Yeah, im using NTFS(Deafault) system, my Hard disk is Toshiba, with 320GB capacity What should i do? Thanks in front.
