Default Turn a raid0 into a raid5?

Can this be done or would I have to backup the image onto another disk and then re-copy?

Thanks,

Ken

You'd have to back up the disk onto another disk, yeah. Then format and setup the RAID5 configuration.

I believe that if you want to change ANYTHING w/ a RAID configuration, besides turning RAID 1 into a single disk or a single disk into RAID 1, you have to format all drives involved.

For singe disk to RAID1, you still have to format all drives.

For RAID0 to RAID5, you also need to reformat. However, RAID5 is usually not recommended unless you have a dedicated RAID5 card since it requires a lot of calculations.

To answer most of your questions: (1) a fridge cannot cool a PC (2) 64-bit OS for over 3.4GB (3) If a PCIe card fits, it should work (4) Resolution, not screen size (5) If you have a question, it is not news (6) Report, not respond to Spam (7) Single-Rail/Non-Modular PSUs are not always better than Multi-Rail/Modular (8) Sequential does not matter as much as random for OS drives

Oh, I thought with a singel disk -> RAID 1, it could mirror an existing drive.

And yes, RAID 5 has a huge penalty for writes, so it does require an I/O processor to handle it, otherwise it'll kill your CPU for the calculations required.

depends on the raid controller... chances are if you didn't spend at least 300 on the controller it will not support array modifications.

Much of what looks like rudeness is not intended to give offense. Rather, it's the product of the direct, cut-through-the-bull**** communications style that is natural to people who are more concerned about solving problems than making others feel warm and fuzzy. Would you like to know more?

I think I can calm down my storage paranoia with a bigger back up drive.
