Dear list, Something happened that I don't think should be possible. I "lost" all thre= e disks in my RAID 5 array simultaneously after approx. two years without any problem. And I fear I will never see my data again. But I really hope some of you clever persons can give me some hints. My system is: FreeBSD 7.0-Release Intel D975XBX2 motherboard (Intel Matrix Storage Technology) 3 WD Raptor 74 GB in a RAID 5 array 1 WD Raptor 150 GB as a standalone disk / and /var mounted on the standalone,, /usr on the RAID 5 I believe what happened was that one of the disks didn't respond for such a long time, that is was marked "bad". And afterwards the same thing happened for the other disks. When I try to boot the system, all three disks are marked "Offline". The BIOS utility for the host controller has no option to force the disks back online. I have another machine with a S5000XVN board and Intel Embedded Server RAID Technology II. The BIOS configuration utility on this board has the option to force offline drives back online. I am very desperate not to lose my data, so I don't know if I dare moving the drives to the other machine and try to make them online again. Do you think I should try? In general, are there any procedures I can try to recover my RAID array? Or is the offline status definitive =96 and all data definitely lost? I guess some specialized companies have the expertise to recover lost data from a broken RAID array, but I don't know. And I don't know the price of such a service. I would really, really appreciate any kind of help. I have backups of most user data, but not of the system configuration (and maybe even not the databases). This is of course pretty stupid. In the future, I will not rely on RAID 5 as a foolproof solution=85 Regards, Jon --=20 *Jon Theil Nielsen*
