External hard drive has lost all its data

 I only use that on the car motor.

For work on the computer, such as partitioning a hard drive, I prefer to use a saw.

Used it for larger files, mainly videos, a total of about 350GB

Had not used it for about 6 months.

Yesterday,I attached it to my Imac. When I opened it, the only thing showing was one folder; "BUDA"

As far as I'm aware it's unusual for a hard drive to suddenly delete everything.  That leads me to believe there is a software issue. That the files  are probably still there.

I also have a laptop, which runs Windows 10 and Linux Mint Cinnamon, as dual boot.. have also tried the Lacie drive on each OS. Same result.


Does anyone happen to know of any troubleshooting I can do?

I will not rehash the answers already given, but in a professional context, I have been that soldier. There exist professional companies that can retrieve data from dead HDDs. They are mostly successful, but they ain't cheap given that they do a clean room tear-down of the dodgy drive to the bare plattens if necessary.

I have twice had to engage such on behalf of clients. In both cases it was 100% successful and oddly also LACIE drives. In both cases it was horribly expensive, yet cheaper than a total loss. I am glad it wasn't on my dollar.

All fixed.

I really hate relying on computers. I usually buy a new one every three years. Probably not this time. Although expensive, the Imac
is proving to be the best computer I've ever had. I also prefer Mac and Linux to windows. 


Was pretty sure the problem was not hardware.  As far as I'm aware, a hard drive will simply not suddenly delete everything, that failure of the drive tends to be gradual. .Turned our it wasn't the drive.

   I found a free app called "Disk Drill" .  It took a few hours, but it found EVERYTHING on that drive. That meant approving each file I wanted recovered. That was then saved to a folder. I was actually quite surprise at how few files I needed to recover. I had most of those files backed up on my Imac

After getting everything I wanted, I formatted the drive and have added  another folder, with video files totalling just over 100 GB. I  will monitor that and see what happens. I suspect the hard drive is on its way out---I couldn't find a new hard drive using external power, so bought this one second hand. Last time I'll do that.

I don't suppose external SSD are available at a reasonable price ?

Thank you for your reply.

Available? Sure. Reasonable price? Not yet but it will happen.

Still does not protect against catastrophic failure unfortunately.

 No computer device is perfect. Perhaps I'm being naive to think that  a drive with no moving parts should last a lot longer

m.2 SSDs have really dropped in price as I understand it. Get a m.2 USB adapter and you're gold.

I've seen external SSDs (via USB port) at Best Buy for less than $50 bucks.

 OK , thanks.

Best Buy? There isn't one in my state.

Checked on Ebay: around $50 for 120GB. $100 for 250 GB, which isn't really cheap against an external HDD. They are around  $100 for 2TB, which is what I would be replacing..  Currently have 1TB drive for Imac Time Machine (back ups) and a  2TB HDD for movies.

Saw a (new) Seagate 8TB external HDD for  $260, with  3 year warrantee.

I'd say external SSD are cheaper than they were, but still expensive when compared with HDD. I already have a couple of 132GB flash drives., so I think I'll stick with what I  I have for the time being.

Thank you for your interest.

bestbuy.com Or Amazon.com. Comparison shopping always recommended.

Indeed, Although I have found Ebay to be a pretty accurate price guide for most things..

I prefer not to shop at Amazon because I don't like the way they treat their employees.


Addendum; I checked. bestbuy.com is not available in  Oz.
