Maybe I should have been more specific, the install disk don't support phoney raid controllers very well, yes you can add drivers after the fact but if that is the only drive you have you are in trouble and are going to wreck the array. The process of installing the software destroys the RAID array you already have in place and all the data is gone. That is not a sign of good support. The alternative is to have a second system where you create a kernel with the proper drivers and modify the install disk to create a new install disk that understands the array that is already there. Not a very good solution that the average Joe can deal with, again that is poor RAID support. > > > The first clue is that is sees the two drives as individual drives > > instead of one combined container. > > An inexpensive RAID controller is just the same as a non-RAID > controller, so you'd best use Linux software RAID. But that is not compatible with anything other than Linux, so if you have Windows, you again wrecked the Array and lost your data. In my book that is not very good support of RAID controllers. > > > Hamish -- Cecil KD5NWA www.qrpradio.com www.hpsdr.com Who knows what evil lurks in the hearts of men?
