Make sure that:
1.) The IDE cable in the enclosure is firmly connected to the hard drive.
2.) The USB cable is firmly connected to both the enclosure and computer. If it's a desktop, connect the USB cable to a USB port on the back of the PC.
3.) The power cable is connected and plugged in.
4.) The on/off switch on the enclosure has been flipped on.
Also, touch the hard drive and see if it is spinning once turned on.
Post the results and we'll go from there.
P.S. Your sister's OS is not a factor in this issue.
I have a laptop Dell Latitude D600 and either my hard drive is bad or it has a virus and I need to fix that. I was told that I could use a External Hard Drive Case to retrive files from that hard drive and could have the hard drive repaired or replaced.
I went and bought a Speed Metal external hard drive case because it was $15. It had no intructions only a mini disk which the sales people told me I would not need because it was not software. I learned how to connect the hard dirve to it, althought the aluminum case does not fit over the hard drive. But it connected. I tried to use my PC to connect the drive but I believe this PC to be to OLd(its a 1989 Micron brand) to use the USB port because the USB ports never really work except for mouses and pin drives.
So I tried to use my sisters PC. It is newer and is a Dell. It still did not work. She has Windows Vista and I beleive this could be the problem but I am unsure.
I am not a tech guy. I am somewhat stupid when it comes to computers but I try to do what I can. I need help anyone can give me as to what I nned to do because I need the files from that hard drive and do not have the money to pay the $200+ I was told it would cost me to fix the problem.
Can anyone help me.
