after a hard drive failure we added one more disk and rebuilt the raid .after successful rebuild it showed a list of bad blocks on channel 0 and target 0.while installing NT it is not showing any bad blocks and autochk is also not showing any bad blocks.then why the raid card showed the list of bad blocks.

which one is correct.should i replace the hard disk.

Hardware RAID (your Mylex Card) abstracts the RAID array disk structure for the operating system. I.e., NT sees only one (very large) disk drive. The disk's deffect list list is handled by the RAID array internally. To access the array, check the bad blocks, and affect whatever repairs you choose, you need to use the Mylex utility software. Depending on your version you may be able to install and access it from within NT (e.g., HP NetRAID you can - our Mylex adaptors you cannot). In case you cannot access the RAID utilities from NT, you'll have to shutdown the server and reboot either from a utility disk / CD or a utility partition on the array (if you installed it). Finally: With SCSI disks you do not need to be concerned about a few bad blocks (hence the ability of SCSI to maitain a defects list). But, if you wish, it won't hurt to replace the disks (as long as you properly fail them out of the array configuration).
