Hello!
I know that a RAID 1 (Mirroring) setup protects your data in case of a hard disk drive failure, but I have few questions about how exactly you recover data after a hard disk failure and how can you transfer files from one of the two drives.
I do not have (yet) a RAID controller so I can't try this for myself.
The setup that I am considering would be something like this:
-ABIT KT7-RAID;
-2 HDD in RAID 1, containing the OS, applications and data files.
And now the questions:
1. If I want to transfer some files from this computer to another computer (in another location), it is possible to do this like you can do with a HDD from a non-RAID setup: take one of the two hard disk from the first computer (from the RAID 1 array), connect it to Secondary IDE from the second computer and transfer the files?
2. What if in this way I transfer files from the second computer to only one of the two HDD from the RAID 1 array, this files will be ignored when I put the HDD back in the RAID array?
3. If one of the HDD from RAID 1 setup crashes, the computer will simply boot from the remaining drive?
4. To be sure that all the data can be restored after one of the HDD crashes, let's say that I disconnect one of the two HDD (I remove the IDE cable). After that will I be able to boot and work normally from the other HDD?
5. If one HDD has a failure, you simply remove it and replace it with another (identical) HDD and then the RAID controller will "resynchronize" the two mirrored drives *OR* you have to start from zero (define a RAID 1 array, reinstall OS & applications and copy the files - this will require a third HDD)?
Thanks for your replies.
