Raid 1 array - removing drives

[Shpitzi]

Need a bit of help on this one, as NAS arent my strong suit.

 I have a buffalo nas linkstation 220 ish with 2x3tb drives in raid 1. 

I have bought a new MB and CAse for my pc, so now i can host the drives in my case.

Is there a way to remove one of the drives, format it (tried to put them straight in, gives me about 6-8 new partitions that i cant access) and copy from the remaining one in the NAS on the "twin" that is in the pc, then just format the 2nd one and add it.

 

Dont have a lot of room to save whats on the NAS on the PC, hence the question.

Is your plan to run the drives in RAID1 on your PC?

No, plan is to use them as normal drives, RAID 0

That's even worse than I expected. No. With RAID0 (hardware at least) there isn't a way to keep the data on either disk and add them to a RAID0 array. All data will be lost when the array is formed. This is because the data is split between both disks. You'll need to migrate the data elsewhere. Create the RAID0 then copy it back.

Thanks for the info.... was hoping i dont have to go through that.

Just an FYI, "normal drives" and RAID0 are different things.

 

RAID0 stripes data across both drives - it combines the capacity of both together into one single 'drive letter', but it also means if you separate one of the drives from the other, the data is useless.

 

"normal" drives, would simply be two HDD's directly connected to the computer - each with their own drive letter.
