Hello all! Actually I use dual boot PC with CentOS4 (kernel 2.6.9-11) and WinXP (HDD 20GB, 512MB, PentiumIII 800MHz), but I have the following problem doing the image with g4u ----BEGIN ERROR MESSAGGE---- wd0: (uncorrectable data error) 8951MB 1.59MB/s wd0d: error reading fsbn 18333440 of 18333440 - 18333567 (wd0 bn 18333440; cn 18187 tn 14 sn 62) retrying wd0: (uncorrectable data error) 8951MB 1.59MB/s wd0d: error reading fsbn 18333440 of 18333440 - 18333567 (wd0 bn 18333440; cn 18187 tn 15 sn 52) retrying ----END ERROR MESSAGGE---- I review the HDD partition with the g4u command "parts" g4u>parts wd0 Found NTFS partition; size 20482812 (10001MB), offset 63 skipping existing NTFS partition at slot e Found Linux EXT2 partition; size 192780 (94MB), offset 20482875 skipping existing Linux EXT2 partition at slot f Found swap partition; size 2040255 (996MB), offset 20675655 skipping existing swap partition at slot g Found Linux EXT2 partition; size 17157357 18377 (94MB), offset 22715973 skipping existing Linux EXT2 partition at slot i 9 partition # size offset fstype [fsize bsize cpg/sgs] d: 39876480 0 unused 0 0 #(cyl . 0-39559) e: 20482812 63 NTFS #(cyl . 0*-20320*) f: 192780 20482875 Linux Ext2 0 0 #(cyl. 20320*-20511*) g: 2040255 20675655 swap #(cyl . 20511*-22535*) i: 17157357 22715973 Linux Ext2 0 0 #(cyl . 22535*-39556*) I'm not sure about the mean of d partition. Somebody has made successful images of Centos4 with g4u?, I really apreciate any ideas. I posted a similar message to g4u but they didn't response yet. Thanks in advance, regards Juan P. Espino
