I attached a USB disk drive to my Suse 9.3 system, created a directory, and started to backup up a few gigs of stuff. It copied for a while, but after a few minutes, it ran into some kind of trouble and wouldn't write any more, even though there is LOTS of space. Now, I can read from it, but whenever I try to write to it, or delete the incomplete directory that was written or create a new directory, it tells me

"rm: cannot remove `whatever': Read-only file system".

Mount tells me that it's mounted RW (Bocachica is the drive in question)-

# mount
/dev/hda2 on / type reiserfs (rw,acl,user_xattr)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
tmpfs on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
/dev/hdb1 on /d2 type ext3 (rw,noexec,nosuid,nodev)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/hdd on /media/SU1010_001 type subfs (ro,nosuid,nodev,fs=cdfss,procuid)
/dev/sda3 on /media/Bocachica type subfs (rw,nosuid,nodev,sync,fs=hfsplus)
/dev/fd0 on /media/floppy type subfs (rw,nosuid,nodev,sync,fs=floppyfss,procuid)


I'm working as root, and anyway the directory that I'm trying to remove is mode 777. /media/Bocachica is 755, and I can't change it because it gives me the "Read-only file system" message.

What am I missing here? Why has this drive become read-only even though it tells me that it's rw? What has changed since it started writing, and wrote at least some data successfully?

Thanks, in advance, for any help.

Were you writing the data as root then trying to remove as user? I know it's stupid and simple but I know that is the stuff I always overlook

Can you post output of the following after you have plugged in the device:

OK, I've learned my lesson. No more cross-posting.

The problem is resolved, as described in http://www.linuxquestions.org/questi...72#post2312572.


Thanks for the help.
