My acomdata just clicks and is not recognized by my computer as even being connected. How can I get it to work.

Sorry to inform you, that once your hard drive clicks, it's already dead and unusable. It is called the "Click of Death" for hard drives.

You may want to try bringing your HD to the nearest data recovery center and see if they could recover the files from the HD to another media.

Thank you and good luck!

be safe
go on line to acomdata web site and down load the driver from there

Try a different cable between the computer and the drive.

Disassemble the casing, and remove the "internal" disk-drive.
If the USB-to-disk-drive adapter has "died", it's possible that the
disk-drive itself is intact, and your data will be intact.

Connect the "internal" disk-drive as a "slave" drive in a desktop computer, and see if it can be detected.

If it's dead, and it's still under warranty, then exercise the warranty.

I would say take the drive out and if you have SATA connectors on your motherboard, connect it directly to you computer and see if the computer will recognize it.  If it does, your enclosure is bad.

Sounds like the drive has seized spindle... Not good news.
Is it buzzing similar to any of these noises: http://datacent.com/hard_drive_sounds.php ?
What you should do is remove the internal drive from the enclosure and connect it directly to the computer. If still buzzing then it's a real mechanical problem...

Try checking your power cord adapter.
I found the same problem was with the cord.
Luckily, I had another Acomdata HD cord to check the problem.

you should check that the connecting cables are connected properly to the mother board.

Check your USB Cable connected possible lost contact problem or the power supply of your optical drive.
