Hey, I just got my custom built pc in the mail TODAY and I want to transfer music and files from my old HDD to the new one. I have  a Seagate 1TB Goflex External HDD that I have disassembled. I am trying to use the usb connector of the external and attach it to the internal hdd that is mounted in a bracket outside of my pc. The connector shows it is getting power, but is not being read from my pc. Any help or suggestions are appreciated Is windows running on this new computer when you CONNECT the USB cable to introduce this old hard drive? With windows running, it should detect this drive as an external if the old drive is healthy and if the external USB/SATA guts are good.Im not using the actual external HDD. Just the connector piece that is attached to the case, to which the usb cable connects to the external. Im using it to go from Internal to InternalWhy not just simply hook up the old drive internally as a slave in the new PC ? ?The way that the BRACKETS are inside I would have to disassemble a lot of the PC just to mount it. I just went old school and tossed it back in the old pc and am using a spare 1tb external to transfer.Also... if the external hard drive is one that normally houses a 2.5" Laptop type HDD and you attach a 3.5" Desktop type HDD to it, you will run into troubles as for there are different power requirements between 2.5" and 3.5" HDD's.

If the drive that came in the external is the same size in dimensions as the drive you are attaching to it then this shouldnt be the cause.

If it is a 3.5" desktop type hard drive that the external houses, then you also have to have the power supply connected to this setup, the same as how it would be powered normally as an external 3.5" drive. The 2.5" external drives are powered off of USB power on most of them. Quote from: reaper2191 on OCTOBER 02, 2013, 07:58:33 AM
