formatting and backing up on a Toshiba external hard disk
Hi,
I have a problem with backing up on my newly acquired Toshiba 1TB external hard
disk (from a 750 GB hard disk).
After connecting hard disk I do:
fdisk -l
and I get (after sda1-sda7):
Disk /dev/sdb: 1000.2 GB, 1000204883968 bytes, 1953525164 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos

Device Boot Start End Blocks Id System
/dev/sdb1 2048 1953523115 976760534 7 HPFS/NTFS/exFAT
I have done the formatting:
[root@localhost kirsten]# mkfs.ext3 /dev/sdb1
mke2fs 1.42.8 (20-Jun-2013)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)

Stride=0 blocks, Stripe width=0 blocks
61054976 inodes, 244190133 blocks
12209506 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=0
7453 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks:

102400000, 214990848
Allocating group tables: done
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
I have mounted:
mount /dev/sdb1 /backup
I have done the fstab:
# Entry for /dev/sdb1 :
/dev/sdb1 /backup ext3 rw,user,noauto 0 0
But when I do the backup I get:
[root@localhost kirsten]# ddrescue -f /dev/sda /media/"TOSHIBA EXT"
GNU ddrescue 1.16
Press Ctrl-C to interrupt
rescued: 6744 MB, errsize: 0 B, current rate: 1638 kB/s
ipos: 6744 MB, errors: 0, average rate: 24977 kB/s
opos: 6744 MB, time since last successful read: 0 s
Copying non-tried blocks...
ddrescue: write error: No space left on device
[root@localhost kirsten]#
It is as if it has'nt noticed that I now have ext3 file system.
Can anyone help?
best regards
torben
