Hi,
I have a problem on a system:
2.2.17-raid soft, running 2x18Go in raid 1
ide with promise 66.

raiddev             /dev/md0
raid-level                  1
nr-raid-disks               2
chunk-size                  64k
persistent-superblock       1
#nr-spare-disks     0
    device          /dev/hda3
    raid-disk     0
    device          /dev/hdc3
    raid-disk     1
raiddev             /dev/md1
raid-level                  1
nr-raid-disks               2
chunk-size                  64k
persistent-superblock       1
#nr-spare-disks     0
    device          /dev/hda4
    raid-disk     0
    device          /dev/hdc4
    raid-disk     1

2 months ago, we got on hdc dma_intr: status=0x51 { DriveReady SeekComplete Error } 
so we decided to change the hdc. hd changed we still get error
so we changed the promise, we got still error, 
so I changed the cable. still error.
so I changed second time the hdc.
still error. grrr 

what hell can it be ?
can it be geomerty ?

/dev/hda:
 multcount    =  0 (off)
 I/O support  =  1 (32-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 2495/255/63, sectors = 40088160, start = 0

/dev/hdc:
 multcount    =  0 (off)
 I/O support  =  1 (32-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 39870/16/63, sectors = 40188960, start = 0

I am making the reconstruction now and I realized it arrived
only sometimes, not always, the system is still running !?

Thanks for any help
