Re: Computer does not know external hd is there
How is this drive powered?
If it is through the USB, then disconnect all other devices so connected[except for mouse keyboard]
You may be make to much demand of the PSU.
If it is separately powered then do this
Start/Control panel/Ad min Tools/computer management/Storage/disk management
to see if the system recognises it.
Device manager to checkout the status of the USB.
Check also the Bios to ensure the USB devices are on.[only if no other USB devices are running

try it on another computer if that dosent work you should reformat your computer but first backup all your data by putting your another internal hardrive on your computer and move all your files you need to the empty hardrive and after that take the hardrive with all your stuff in it off the computer and then reformat the hardrive which the external hardrive does not work on and install a new operating system then put the other hardrive with all your stuff back on your computer and transfer your stuff into the hardrive with a operating system then try the external hardrive
OR you can burn all your stuff into a CD or a DVD OR you can put all your stuff into FlashDrives and then after you reformat the hardrive with an operating system put your stuff back into the computer and after that the external hardrive should work
May seem like a silly question you are not booting up computer with ext drive still plugged in are you?
i am assuming your operating system is on the internal drive.
if so don't have the external plugged in when you start up.
I would assume the dvd player encrypted the drive so you could not copy the movies from your dvd player to your computer, so you could not burn them to prevent piracy. If you wanted to use the hard drive in your computer you will need to format the drive.
put in your recovery disc and follow the instructions on it, you may need to reinstall the drivers and os....i just worked on a laptop with media center and thats what needed to be done, it was the same with the rebooting and video stuff, make sure not to activate the mcafee antivirus if it's out of date or subscription is up, it will not allow your puter to run properly, the other thing i discovered with that...hope this helps hun....shia
Most portable HDDs show up without drivers being required, so, assuming other drives or USB devices show up the general assumption is that either the circuit board in the enclosure has failed or the HDD has failed.
Assuming it doesn't work on other PCs and that other USB devices do, take the external drive to your local computer shop and ask to have the drive tested and moved into a new enclosure. If the drive is OK then the people at the computer store can simply transfer the drive into a new enclosure and it will work. If it fails testing you will likely need to send the drive to a Pro, I would recommend Armor-IT Data Recovery(listed in the FixYa directory).
You can swap the enclosures yourself if you have basic hand tools and are feeling handy but it might be nice to have the techs at the local shop test the drive.
If you need any further instructions add a comment on this post and included the make and model# of the failed external drive and I will offer further assistance.
If you really can not get it to work anymore, you could try opening it up and connecting the hdd directly on a IDE/SATA port in your computer. This will only work if you have a desktop, for a laptop you would need all kinds of converters.
