Broken Computers and Hard Drives

My computer is broken and I would like to retrieve all data, but especially photographs, from it. External USB Hardrive (WD 2TB Passport) fell off desk landing vertically on floor, connector side up. Now when plugged into my Mac, the drive makes a clicking noise and the light flashes. The drive doesn't show in Finder, but appears in Disk Utility, however the single partition is greyed out as if eject. If it makes any difference, the drive was plugged into my RAID server when it broke, however the data had started copying off the drive yet. The drive was about 1/3 to 1/2 full with data, with the majority of it being audio files.

I have and WD Exteranl HD giving a message " the request is failed due to a fatal device hardware error". It has a lot of very important backed up files which I'm desperate to get to as my laptop has been stolen. I wonder how much it cost to get the data off? How long it would take and if you are open next Monday

Failed/failing standalone hard disk. Host OS generates SATA errors (command failures, resets etc.) when trying to access the drive. SMART self tests fail with read errors. Drive is branded as a Samsung "Momentus" but is actually a Seagate ST1000LM024 2.5" 1 TB SATA (used as an external drive via USB). Would like to explore options for data recovery.

My Seagate expansion hard drive is not showing up on my Macbook. I've tried on my friends macbook and it doesn't turn up on disk utility either. There's no problem with the wire as I used it with another hard drive and it worked fine. There are sounds coming from the hard drive that are identical to my other hard drive when plugged in. I'm hoping you'll be able to help with this.

I have a G-Technology GDRIVE Ev ATC External hard drive. I have been using this on my mac book pro for the last 18 months no problem. I have just tried to use it but it is not showing up in the mac book finder. It is showing up on Disk Utility but the volume is greyed out and unmounted. The hard drive light switches on when plugged into the laptop and the hardrive is vibrating suggesting that it is on. But I desperately do not want to risk loosing the video files and video editing projects that are on the hard drive. Is there a way of opening the hard drive and saving the files somewhere else? I am leaving the country on Sunday so this is quite urgent!
