DBCC CheckDB The operating system returned error 21(The device is not ready.)


Will Indian Rupee Cross 55??


Following error can be very difficult to deal with this error if not dealt properly.

"DBCC CheckDB The operating system returned error 21(The device is not ready.)"

Please follow following steps carefully.

1. run xp_readerrorlog and find the recent errors.
2. run xp_fixeddrives to see if all the drives can be read from sql server.
3. Look for the eventviewer. The issue can be some RAID controller or other h\w sources.
4. Don't detach the DB.
5. Look for restoring the latest backup if the problem is still a panic.
6. Do NOT restart neither your m\c nor your sql service.


Along with technical learning I would like to share some great articles for anyone interested in the betterment of his/her family life
