Thank you for answer. I know "media error" mean disk going to bad. I want to know why "slow initialize" did NOT complain bad block. Based on DELL document "slow initialize" will check bad block.

We have DELL server with MD1000 Disk array in
it. O.S. is CENTOS 5.5.
Recently every time MD1000 "patrol read" start I will
get "media error"
messages on /var/log/message file.
I use MD1000 "slow initialize" to initialize "bad
disk" and NO error.
After "slow initialize" finish, I manually "startup
patrol read". I
continue get "media error" on /var/log/message.
Anyone know what difference between "slow initialize"
and "patrol read"?
No, but let me suggest to you that "media error" means just that, a bad drive.
