Solved computer hard drive adapter

Specs: Windows XP
I'm trying to use a USB To sata/ide adapter model ADA-2020-D. I have 2 hard drives from a HP laptop. they are both Toshiba hard drives. When I plug them into the adapter you can feel the drive spinning. But the computer does not show them. I've tried using vista and an XP operating sytems. Tried plugging in while running and tried booting with the adapter plugged in. thanks for any help.

You do know there are a lot of posts on that model and they have similar issues.

Might need an external power supply for them.

Edit Opps misread the boot deal.

✔ Best Answer
The USB port (or two ports) you plug the ADA-2020-D into MUST be able to actually supply 500 ma of current.
If you plug it into a port in an external USB mult-port hub, or a port in a mult-port USB hub up higher on the front of a desktop case, or one of the front ports lower down on the front of a desktop case, it may NOT be detected correctly.

The same things that apply (regarding USB ports) to external hard drives in the following also apply to the ADA-2020-D

Troubleshooting USB device problems including for flash drives, external drives, external memory card readers.
See Response 1:


When it IS plugged into a USB port (or two USB ports) that it does work with properly....

- If the computer has Windows 2000 or higher on it, the operating system will probably install generic drivers built into the operating system for the ADA-2020-D, automatically.

- If the computer has Windows ME or previous on it, you probably must install drivers for it BEFORE you first plug in it's USB connection.

For some desktop mboards you can have problems when an external hard drive is plugged into one of a pair of USB ports on the back of the case that are connected to the same USB controller, if there is another device plugged into the other USB port for the pair, because the pair can't actually supply 500 ma per port - they can only supply 500 ma in total. Usually those pairs of ports are one above the other, not beside each other. If you have two devices plugged into such a pair of ports, try plugging one of them in elsewhere on the back of the computer.

For MANY laptop and netbook mboards similar applies. The built in USB ports often cannot actually supply 500ma per port - they supply 500 ma in total for two ports that are close to each other. In that case, the ADA-2020-D should work fine if it's the ony thing plugged into the USB ports built into the laptop or netbook, or if you have more than two ports, the only thing plugged into two ports close to each other.

using my laptop I unplugged all usbs and only plugged in my adapter. I was able to find files on the HD. Turned off computer and went back later to retrieve more files, now it can't find a driver for it. Laptop is using vista. Thanks again.

Thanks for the thanks.

NO specific drivers are needed for external hard drives in XP or later versions of Windows, and probably 2000 too.

(When the external hard drive is being correctly detected by Windows, the P-n-P (Plug-n-Play) ID string provided by the external enclosure's circuits "tells" Windows which generic drivers Windows already has built into it to load, in order for Windows to recognize the external enclosure's circuits, and when Windows recognizes those external enclosure circuits, it recognizes the hard drive inside the external enclosure.)

However, if you unplug the external drive WHILE Windows IS RUNNING, WITHOUT clicking on the Safely Remove Hardware icon and choosing to STOP accessing the drive letter, or all the drive letters if the external drive has more than one, you can DAMAGE data on the drive, such that....

- the drive letter(s) for it DOES NOT show up in My Computer or Windows Explorer

- or the drive letter for it DOES show up in My Computer or Windows Explorer, BUT

- when you click on the drive letter you get a message indicating Windows doesn't detect it as having been formatted
- or - you can see files or folders on the drive but you can't access them when you click on one or more of them, or all of them.
- or - you can see files or folders on the drive but some of them that you know were there before are not listed

If you HAVE damaged data on the drive, you can probably fix any of those problems and get access to all of or most of your data back if you use certain prob grams to repair the data damage.

See the info at the link in response 2.

If you get "Access Denied" messages when you click on certain files or folders, or for all of them, that's a different subject.

NOTE: you probably have to reboot the computer before the settings you change actually take effect !
