I have three external hard drives and a secondary drive that I take out of my computer every time I send it in for repair. When I take it out I put it in an external hard drive case and use it in by backup computer. Recently HP sent me a new secondary drive. Thus, I replaced my 2007 120 GB secondary drive with a 2011 160 GB. This week was the first time I have had to send my computer in for repair since getting the new secondary drive. I found that my old external hard drive case would not read the new secondary drive in my old external hard drive case. On Tuesday, I ordered a new external hard drive case. They are somewhat similar but the new one uses a slightly different interface. The old one had a USB connection at the external drive end and a double USB connection at the main computer end. The new one has a mini USB conneciton at the external drive end and a double USB connection at the main computer end. Now, it reads on my backup laptop (2003 Dell Inspiron 8200 with USB 1.0 connections). It seems the connection is stronger with this new connection because one of my other external hard drives did not work on my backup laptop because I had a mini USB-USB connection cable that did not supply enough power from a USB 1.0 drive. It worked on a USB 2.0 with just the mini USB-USB connection. However, on the USB 1.0 drive it suddenly communicated with the mini USB-double USB connection. Can anyone offer an explanation?
