Not purely a partition question, but I don't know where else to put it...
I have an external 1TB HDD that I use for back ups with Grsync.
I use it as 2nd safety copy; taking a back up from another external HDD.
Suddenly it turned into "read only", while in Properties the owner is still me.
The Grsync-forum says it's not a Grsync flaw, but more likely something wrong with the hardware.

I have (with the help from computerhope-forum) found this similar problem, only it concerns an ntfs, whilst mine is FAT32:
https://bbs.archlinux.org/viewtopic.php?id=104411
it leads to another thread, which is even more specific ntfs:
https://wiki.archlinux.org/index.php/NTFS-3G
Trying a suggestion from the first link gives me this

Code: Select all

ludo@ludo-IXLs ~ $ sudo fsck /dev/sdf1
'fsck' uit util-linux 2.20.1
dosfsck 3.0.12, 29 Oct 2011, FAT32, LFN
There are differences between boot sector and its backup.
Differences: (offset:original/backup)
  65:01/00
1) Copy original to backup
2) Copy backup to original
3) No action
?

which doesn't mean anything to me.
Can you give me another clue how to solve this?

BTW at a friends pc I plugged the HDD into Xubuntu and there did succeed in doing a "sudo cp xyzfile /media/mydisk/backups" without error.

Please check the output of "dmesg" to verify that the file system driver is not failing out into read-only mode due to detected file system inconsistencies.

Last night just before crashing (me, not the disk ) I found it.
In Gparted I had to run a "Check" on the unmounted partition, et voila...
I found the idea in an old Ubuntu thread
