I'm a software developer and just started my professional career life, question here i want to ask is ... that few days ago i was at client site to resolve some issue in application deployed by a company that uses MySQL for database, what i was found that there are four MySQL tables were crashed due to low harddisk space issue (I've searched on net that this is a usual problem with MySQL) that then i repaired by using <code>myisamchk</code> command. Error shown by MySQL when these were accessing is <code>[table name] marked as crashed and should be repaired</code>.
ok so this was the background scenario, now what i want to know/ask here is ... as described in above details that these 4 four tables were not accessible becuase they are crashed but I took a backup of this database and restore it to MySQL at another machine then i can access these table easily with no issue/error by MySQL, SO WHY THIS HAPPENS THAT AT ONE SIDE THESE ARE AS CRASHED AND ON ANOTHER THE BACKUP OF SAME DATABASE THAT WAS TAKEN WHEN THESE TABLES ARE CRASHED ARE THEN WORKING FINE.
I really will appreciate any kind of help on this topic Im just asking this for knowlegde and second thing is my boss also asked me the same question
