No one would give a waranty that this would work! My gut feeling says that the software raid tools would not destroy the data from the first disk, but just mirror it to the second one. But again, if it trashes your harddrive, you are on your own. Can you afford some sort of backup?
One trick that I would suggest is (and you are still on your own if it fails): - install the second drive. - make a raid 1 with only that drive in it. - make file system on that raid device (usually md0) - copy all your files to that raid device. - check if the files are intact. - erase your old hardisk, and then hotadd it to the raid device. If step two fails, then you can probably create the raid 1 with 2 devices, that second drive and one bogus drive (/dev/hdsomething). Your raid will be in degraded mode when it is created. When both drives are in the raid, then do a hotremove fror the bogus drive. You can play arround with software raid tools by creating several small partitions in the new harddrive and then raid them. See if raid tools would allow you to do raid 1 one device. See if it will allow data in the primary partition if it is raided with other device. If you do these tests, let me know your results. I am doing several test with software raid tools myself.
