I have an external hard drive made by RetailPlus with a 500GB Western Digital hard drive in it. I've tried it on 3 different pcs and each time it shows up in device manager but not in My Computer. Also none of the pcs would shut down until I unplugged the usb cord from the hard drive. I also took the hard drive out of the enclosure and plugged it into an external sata port on my friends pc and windows wouldn't startup until I took it out of the port, then once I plugged it back in while in windows it didnt show up anywhere. I tried a second time in windows through the ext sata port and received a BSOD. Thank you.
