Hello, a few years ago I bought a LaCie HDD of 500 GB. The warranty already expired when it started to show signs of problems. Eventually the HDD failed to the point that I could not use it. I opened the case and saw that there where two HDD of 250 GB each so I realized that maybe just one of the HDD is bad while the other is in good conditions. The problem is that they seem to be under some kind of RAID (I don't know much about RAID but it should be RAID 0 as it joins both drives to make "one"). I tried to remove the RAID somehow in Disk Utility but nothing shows up under the RAID section. I tried to open RAID Utility but it says my computer does not support it. Can anybody please help me to remove the raid and use just one (the healthy drive)? It should be simple but I am ignorant in this area.
Also, which program may I use to check which is the healthy and the bad drive? Does such program exists?
Thank you very much! Hope you can help!
