I have a web server. About 100-150 virtual hosts. Just small websites. My first post is here: SATA hdd errors , but now I have new error on other disk. 1. I have problem with sata disk as described in the link. 2. I have put in other disk and... no luck, mkfs.ext3 - and on a new disk the same issue a lot of errors while mkfs is running. 3. Next step was to replace sata cable and this helped. after that I was able to format disk and have started file transfer from backup. So it is now 4 days since cable and disk change.. and now I see the following message in dmesg:

Question 1: What does it mean, and what can be the problem? (I found in Google that 99% it is cable problem)
Question 2: Raw_Read_Error_Rate increases by 20-30 every day. Is it Ok? On disk sda value is 7000 and no errors.
