the best thing is to follow the following approach:
Lately, a lot of my Linux boxes have had hard drive failures. There are about 15 servers running raid 1 on Red hat 7.3. Does anyone have any suggestions, maybe some good doc's, on hard drive troubleshooting / tuning? Some of the failed hard drives are only a couple months old, and have already been replaced twice, so I suspect a faulty ide controller. What is a good IDE controller card to buy for Linux?
+ to download a disk utility from the manufacturer to check the integrity at low level of your hard disk drive. + after discarding this possibility, go ahead with fsck checks on your hard disk drives (linux checks). + if both of these checks are negative (no problem at all), then you should start checking something with your configuration of your RAID controller.
Anyway, googling a little bit about your Hard disk drive model and RAID controller could give you a few clues if there have been problems with that configuration in the past...
BR,
Miguel
