  • 3 bit parity

    I was just reading about parity on searchstorage.techtarget.com and have a question about 3 bit parity vs. 1 bit parity. I understand the setting to 0 for an even # of bits and setting to 1 for an odd #. Doesn't seem very reliable because you could lose 2 bits in data transmission. Just wondering...

  • Question about RAID 1

    I have a server with a RAID-1 array with 2 36 gig hard drives. I am wondering could I get another 2 hard drives and add them to the array, and then extend some already partitioned space without formatting?

  • What are the signs my RAID array is dying?

    What are the signs that my RAID array is dying? Are there checks I can run? Can I add a hot spare to a RAID array with 6 disks in it? Will this help if one drive fails? What if multiple drives fail, what do I do then?

    Hi all, I wrote not long ago about the best way to upgrade disks when using RAID1.

I used Ghost for this, by making a backup of first the system volume, then the data...

  • Add a drive to a Raid 5 without destroying the data

    Can you change the amount of drives in a raid 5 array? For example we now have 6 136 GB drives in our raid 5 array. Can we add one more drive to the array as either a hot spare or actually part of the array? Currently the array uses all 6 drives.
