My main backup drive seems to have failed - I've only had the thing 5 months! It's a Lacie USB3 2TB one, nice drive I thought with a metal chassis and very quiet. I use it to share and backup files from my Mac and Windows laptop so it was NTFS formatted (on Mac I use the Paragon NTFS driver which is supposed to be safe), but now on the Mac it won't mount at all and on Windows it is showing in the Disk manager but can't be read and shows up as RAW (but it also says it's healthy). I ran a disk error checker (HD Tune) on it and it also showed no errors physically but it just doesn't seem to have any data on it any more (it had over a TB of backups - luckily most are dupes of stuff I have on other drives apart from a few recent downloads that I hopefully can do again)

Any way to fix it? I could of course return it to the shop I suppose as it's in warranty but I want my data if possible.

Lacie have had very bad press on KVR. Seems that the PSUs/Interfaces are prone to fail. The drive should work as normal if you remove it and put in another box or the PC.

i'd just take it to a computer repair shop to see if they can salvage the data, is it still under warranty?

If I do that it loses the warranty - is this an internal psu or do I just need to change to a new power adapter?

Yes it has a 2 year warranty but I'm not sure if the shop (PC world) would honour that or expect Lacie to fix it

I thought Lacie were supposed to be good. My older drive is a seagate and it constantly clicks so I was afraid it was dying and bought the Lacie to back that up. That one is still working though. is there any brand that is reliable?

Seagate/ Western Digital. Look out for drives that have over 1 year warranty. Anything you get above that is a bonus, they all fail.
