Mok3,
Sorry to read you're having the trouble, but it appears th eRAId may have to be rebuilt. I should say right away that I'm almost completely inexperienced with RAID as the result of hearing so much about it! I have a Dell Precision with a software RAID 1 and was given a Dell Poweredge 2600 server, with 5 disks in a conservative RAID 1 and RAID 10. The more I learn about RAID, The more I realize I don't want to get too close !
SSD's performance is noticeably enhanced with RAID 0, but the problem with RAID 0 is that it's very difficult to rebuild. On the Poweredge, the RAID 10 takes more than 24 hours and that's with 76GB 15K SAS disks. If your RAID 0 needs to rebuilt, my limited understanding is that it needs to have a sequence of analysis, block size, striping fragment analysis, in which a sample file decodes the way the stripes are arranged and has to, in effect, synchonize each bit between the two drives. If you are rebuilding a 480GB RAID 0 it may take several days and I'm hoping you are running ECC RAM as my understanding is that RAID 0 rebuilding is absolutely fault intolerant- a one bit error is fatal and will be accumulated.
Another consideration is to analyze whether the performance benefit of RAID 0 is worth the expense and trouble. I looked into a fast RAID controller for my HP z420 (LSI 9260-8i but I learnd that for my HP workstation, a RAID 0 might only take 1 or 2 seconds off the boot time and on a very large file transfer _ often backup 40GB or more- save 20-40 seconds or so. As a result, my tactic is to use a single, fast, enterprise SSD and incremental backup to a 1TB enterprise mech'l drive. I am considering however, adding a software RAID 1 to my HP.
There are many guides on how to do the RAID 0 recovery, and here is one that seems quite clearly written:
http://www.raid0recovery.info/manual-raid0-recovery.aspx
> and describes both manual and automatic methods.
I hope this helps. Putting the task into perspective, if you have not lost files, to get back to work sooner- saving the research and learning of the techniques and waiting for the rebuild, it may actually be easier and faster to reload everything on a single drive, making a pristine system restore image, and then building a new RAID 0. If there ever again a RAID failure, quickly restore from the system image to a single drive, get back to work, and then run the RAID rebuild overnight . If the media files you mention are irreplaceable, then a rebuild may well be necessary.
It may be also a thought to rebuild as RAID 10, which you can do on two drives, but you will end up (I think) with 1/2 capacity- that is the 2X 480GB drives will give you 240GB.
Let us know what happens!
Cheers,
