usb hard drive unmounted automatically
I am using Ubuntu 8.04 Hardy Heron on an AMD Athlon 1.2 GHz processor .
I'd like to save the data on my home partition as I have the impression the hard drive hosting it is going to "die" soon .
I've bought a USB Sata hard drive of 320 GB and actually the volume of data I'd like to transfer is far lower, around 15 G .
I've formatted two primary partitions on the drive .
One is ext2 (30 G) and the other one is 260 G with reiser fs .
I use the following command to save my datas :
sudo nice -n 19 rsync -P -av --exclude=".*/" /home/cedric/ /mnt/home/cedric/
Here is the problem :
A few files get transfered and each time, it ends with I/O error messages and the device file /dev/sdc2 representing the reiserfs partition gets deleted .
Listing /dev directory, it appears that the two partitions are renamed as /dev/sdd1 and /dev/sdd2 .
I've tried to mount /dev/sdd2 instead of /dev/sdc2, but the same scenario repeats : I/O errors, /dev/sdd2 deleted and creation of /dev/sde2, etc...
What do you think about this ?
Thanks a lot for your help,
