If the other tools fail to read files, then you might try to use ddrescue <http://www.gnu.org/s/ddrescue/ddrescue.html>. Ddrescue doesn't fail at the first failure to read the disk. It tries multiple times. This can take a LONG time, though. Try dd_rescue if liveDVD's, clonezilla, and dump fails. If all other tools fail, then use dd_rescue to save the image to another device. You can then run fsck and mount the image to transfer files that might not have transferred before. Be sure to compare files before blindly copying them, though.

Plus, dump goes directory to the device rather than through the kernel's VFS layer, so you don't even need to mount the filesystem. Anytime someone says to use 'dd' I always suggest the filesystem's dump|restore. There is a time and place for 'dd', but in most cases I've encountered, dump and restore is the better choice. Plus, you can format the new disk with your choice of filesystem, often with more appropriate settings (block size, features, size of partition, etc.). -- Jonathan Billings <jsbil...@umich.edu> College of Engineering - CAEN - Unix and Linux Support _______________________________________________ rhelv5-list mailing list rhelv5-list@redhat.com https://www.redhat.com/mailman/listinfo/rhelv5-list _______________________________________________ rhelv5-list mailing list rhelv5-list@redhat.com https://www.redhat.com/mailman/listinfo/rhelv5-list
