Hi, I'm using and RPM of ddrescue obtained from:
http://www.cert.org/forensics/tools/centos/cert/6.2/x86_64/ddrescue-1.15-1.el6.x86_64.rpm http://pkgs.repoforge.org/ddrescue/ddrescue-1.15-1.el6.rf.x86_64.rpm This is on CentOS 6.2, 2.6.32-220.7.1.el6.x86_64 I have a 3TB Western Digital SATA drive, directly connected, recovering to an image. The image is being written to a 8.2TB ext4 partition. The disk is from a WD USB enclosure, that is also failing, hence the direct connection. The WD enclosures encrypt the disk by default, hence the raw recovery. On reaching a recovery image size of 2TB, ddrescue fails: # ddrescue -B -v -n -T --block-size=4KiB /dev/sda ./sda.dd ./ddrescue_logfile_LOCAL.log GNU ddrescue 1.15 About to copy 2793 GiBytes from /dev/sda to ./sda.dd Starting positions: infile = 0 B, outfile = 0 B Copy block size: 16 sectors Sector size: 4096 Bytes Max retries: 0 Direct: no Sparse: no Split: no Truncate: no Press Ctrl-C to interrupt Initial status (read from logfile) rescued: 1688 GiB, errsize: 69052 KiB, errors: 17263 Current status rescued: 1688 GiB, errsize: 69052 KiB, current rate: 0 B/s ipos: 2047 GiB, errors: 17263, average rate: 0 B/s opos: 2047 GiB, time from last successful read: 1 s Copying non-tried blocks... ddrescue: write error: File too large The ext4 filesystem has the "large_file" option enabled.

Any assistance would be appreciated.
