Re: Need help in recreating .MYD files
hi, Just to add up i have read some where ( i assume in the mailing list only) that OS recognizes the file based on few codes added at the starting / ending of a file. So there are ways to create a MYD file through vi editor as well (this is not from the angle of restoring the data in that table). As Daniel said if there is no binlogs/ update / query logs there is no way of restoring data to the current date. -- Regards, N.PradeepChandru, MySQL DBA, Cricinfo Pvt Ltd.

You need a special MySQL created data file with lots of headers and content. mysql desc userdetails; ERROR 1105 (HY000): File './everest/userdetails.MYD' not found (Errcode: 13) but the file is exist. Exists, but its invalid in all aspects (size 0, no headers, no content). tell me how i can get the data. You must understand that the .MYD file IS the data. So, to recover it, you'll have to just use another source (backup, binlog). A backup is usually an sql file, you'll have to recreate your table and populate it with the data on the backup, or, if your backup has the structures, you'll just have to use it to recreate the whole database. The binlog files logs all queries to the server, this way, it can recreate the changes on the database, but that requires a snapshot of the state where the binlog started. Another option would be to try and recover the lost files from the filesystem, but all the commands you issued and the simple fact that your system is running may have already overwritten the free space that your files used to take. And besides that is an expensive and tecnical solution. In simple terms, if you have no backups, your binlogs are outdated or rotated to an extend (old changes lost) and you can't recover the files from the filesystem. You're pretty much f up (don't get me wrong, It happened to me once, and now I have daily backups, a replicated server and binlogs saved daily too). -- Daniel da Veiga Computer Operator - RS - Brazil -BEGIN GEEK CODE BLOCK- Version: 3.1 GCM/IT/P/O d-? s:- a?

Re: Need help in recreating .MYD files
Hi, If you have deleted .MYD files then truncate the table and restore it from the backup if yu have. MYD means your precious data which contains. balaraju mandala wrote: Dear Comunity, I need your help. I accidently deleted some '.MYD' files.
