I have a external usb hard drive by HP, dvd550s-H03 8 which my dell XPS computer is not detecting. Seems like the hard drive does not need any drivers. So that is not an issue. Can someone help me a bit here ?
Please try connecting the USB drive into an alternative USB port and see if it helps. You may also try using an alternate USB device such as mouse, flash drive etc to verify the functionality of USB ports.
If the USB ports are not working properly, you may follow the steps below to uninstall USB root hubs and restart the system :
If the issue persists after refreshing USB root hubs, you may update the chipset drivers from Here -> Enter the Service Tag of system -> Click on Drivers and Downloads -> select the operating system installed on your computer -> Expand the 'chipset' category and download/install the drivers -> Restart the computer when prompted and check if the hard drive is getting detected.
If you have any questions, please share the system model along with the Operating system installed on computer. Will take it further from there.
I did all the above an my hdd is still not being recognized. My service tag is: 8m1vm32.
