I have an E310 Dell Dimension with two hard drives one mirroring the other. The main one has failed but the mirror works fine. I want to replace the main hard drive, move data from the mirror, and continue using the computer.

 

I know how to take the hard drive out etc but I don't know how to recover the data from the mirror hard drive. I have the original operating system disk which I can load on the new main hard drive. Thanks, Platte

I am not familiar with RAID setups but while waiting for further suggestions, see http://www.vantagetech.com/faq/raid-0-recovery-faq.html or http://www.vantagetech.com/faq/raid-1-recovery-faq.html

If it's a mirror setup...the data reflected on drive 1 should be the same as that reflected on drive 2.  There should be no difference between the two.

 

From wikipedia, http://en.wikipedia.org/wiki/RAID .:

 

"RAID 1:  In RAID 1 (mirroring without parity or striping), data are written identically to two drives, thereby producing a "mirrored set"; the read request is serviced by either of the two drives containing the requested data, whichever one involves least seek time plus rotational latency. Similarly, a write request updates the stripes of both drives. The write performance depends on the slower of the two writes (i.e. the one that involves larger seek time and rotational latency). At least two drives are required to constitute such an array. While more constituent drives may be employed, many implementations deal with a maximum of only two. The array continues to operate as long as at least one drive is functioning."
