Hi everyone,

I am trying to see if I can power up my old 500gig LACIE N2870.  The trouble is that I lost the power adaptor for it and it has been sitting, unused, for over a decade, but when it was still working when it was initially stored.  It's a square enclosure designed by Neil Poulton and there is no identification visible on the enclosure except for N2870 visible on one of the rubber feet, CR2S HD3.5S2 with a number on another foot,  LACIE printed on a third, and a square logo on the side of the enclosure.  

I contacted seagate and they recommended a 5v 2a power adaptor but when I used this adaptor, the drive would not power up.  No noise, no light, nothing at all. The internet says that this particular enclosure uses a 12v power adaptor so I am wondering if this is the problem, although the enclosure might be dead.  I don't see any visible damage anywhere and it has never been dropped to my knowledge, so I am confused and wondering if this is salvageable.

I was looking for some old projects and I thought they were on one of my PCs but I can't find them anywhere.  This is music I have written during my undergrad and masters.  I have hard copies of most of my undergrad scores but I don't think I have any for the masters music.  If worse comes to worse, I might have to contact my alma mater for the submitted hard copy of my thesis.  

The issue is that I kicked over my newer 4TB Phantom Drives external drive when it was operational and the header started rubbing on the disc so I think that drive is toast.  I had backed up the entire LACIE drive on this other drive so I had never managed to find a replacement power supply for this unit back then although I definitely should have!

I have one other option:  I'm asking my brother if he knows where all my old USB sticks are at my mom's house.  They also have a HDD from my old work PC I used for my masters and doctorate, so I'm going to get an external drive bay and see if I can power up that HDD as well.  I was so fastidious about copying over my projects that I'm super annoyed I missed this.  At least I have everything from my doctorate and since then, and my more recent work is all saved on multiple drives, cloud services, and external drives.  
  
Any and all advice is welcome and much appreciated.  This is rather stressful!
