    Please specify - what do you mean by "they won't backup"?

    What Raid level are you using? Raid 0 (hopefully not) Raid 1, Raid 10 or Raid 5? If you are using Raid 5 or Raid 1, change the failing drive as soon as possible. If the other drives are from the same vendor and production date, it could be, that they will fail too very soon.

    Don't do the backup while avid is launched because it could be that avid locks some files when they are used.

    This is a prob that should be handled from your os, close down all running apps and check if you have a program called Intel matrix storage manager.

    You could have another app than this one controlling your raid but this one is the most common I think.

    From that app you have some ways to verify your raid.

    But, as Andrew says, first try to just copy your files to another drive using the common tools in your os and with no other apps opened up.

     And, about raid 0 or striped raids, I see no more probs with those than with common discs, as said, there are tools to control them and tell you when it is time to act.

    Sorry - that is not right. You have twice the risc of a HD failure because 2 HDs are involved. If only one HD fails - ALL your files are lost - and no chance of recovery. So for my opinion it's absolutely not recommended to use a Raid0 set if you work in a professional way. Use Raid 10 instead. Same speed but also a secure storage.

    Re: HELP!!!! Raid Drive Error

     Unfortunately I have a Raid 0. Wish I'd known this before I purchased. Would have got a Raid 10. Thankfully my project was done and I got it dumped to tape before the drive completly crashed. I'm definitly looking into different storage. How about some sort of external Sata drive? Are they more secure than the Raid drives? I really would like to have at least a couple terabytes. Thanks for the info.

    Re: HELP!!!! Raid Drive Error

    I don't know the exact details of your system, but normally you should be able to "upgrade" to a raid 10 array. All you have to do is to buy 2 extra hd drives that are equal in size like the two you got allready in your raid 0 array.

    Put them in your system and reconfigure your raid to raid level 10. But beware: You may lose all data on your raid drive when you reconfigure it to raid 10. If you don't know exactly what you are doing, backup all your data first or ask some professional computer specialist to do this for you.

     

    Some Info about the raid levels:

    Raid 0: The data is devided on two hd drives - If one fails your data is lost. You get higher transfer speeds with raid0 because 2 drives deliver your data faster then one.

    Raid 1: The data is mirrored to two hd drives - If one fails you can automatically use the other drive. Your data is secure. Speed is the same as if you would use only one hd.

    Raid 10: Two hd drives are mirrored to get the higher speed. These two drives are mirrored to two additional drives. You've got high speed AND secure data storage. If one drive fails, you can still use your data with no loss.

    Raid 5: 4 (or more) hd drives are used to save your data. The data is devided on 3 of them and the last drive is used for parity data. If one drive fails, the system is still usable and no data loss will occur. It is not as fast as raid10 but you have more storage capability for the same price as if you use raid10.

    So buy two hard drives and configure your raid as raid 10. I think that would be the securest and cheapest way in your case.

    pro---studio:
    aid 10: Two hd drives are mirrored to get the higher speed. These two drives are mirrored to two additional drives.

    Actually, what you've described there is really RAID 0+1, which is slightly different from RAID 10. RAID 10 involves 2 drives that are in RAID 1 (duplicated), and then striped across another RAID 1 mirror (in RAID 0.) RAID 10 is more technically secure than RAID 0+1, because in certain cases a second drive can fail in RAID without losing anything. In this case, 1 drive in each mirror can fail.

    Hope this helps!
