Upon returning from a short vacation and powering my system back on I neglected to check the video connection and powered the system off thinking it failed to boot. After discovering the true cause of the problem Linux Mint was giving errors on accessing my data partition on boot. Booting from a live CD and runnning "sudo jfs_fsck -avpf /dev/sda7" now produces this result:

Unfortunately googling for a solution resulted in only about six hits; two of which appear to be approximately the same as my problem, however I see no actual resolution to the problem either in the 2005 or the 2008 reported cases. Is there a solution to this problem yet? Even if it were possible to access most of the data by mounting read only, I can't even recover my data to another drive at the moment because I have not yet come up with the financial resources to purchase another terabyte drive for backup purposes. I am quite nervous at this point regarding my data. Can the partition be repaired or is the only option to copy all accessible data to another partition and reformat? Is there any way to find out exactly what data is in the blocks affected and if so and the data is determined to be inconsequential, can the problem be cleared up by deleting or overwriting the blocks? ------------------------------------------------------------------------------ _______________________________________________ Jfs-discussion mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/jfs-discussion
