This isn't too unusual; if as you say the drives are fine then I'd agree it is probably a controller issue. I've got a RAID that does this regularly and you normally find in the log somewhere an IDE error of some type (typically it dropping out of DMA due to a busy or it not responding).
I've given up using multiple IDE PCI cards for this - they only just work, and occasionally you'll get a glitch like this. I've tried a mixture of Promise and HPT cards. In the end I gave up and got a 3ware IDE RAID card which is working fine (you could just use it as a large multichannel IDE card and run soft raid if you want I think).
