I'm trying to reduce the size of a backup drive image. Original disk had these partitions:
Model: ST916082 1A (scsi) Disk /dev/sde: 160GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 65.7GB 65.7GB primary ntfs boot 2 65.7GB 160GB 94.4GB extended lba 5 65.7GB 160GB 94.4GB logical ntfs
Image was created from the logical partition using the command
> sudo ddrescue /dev/sde5 datapartition logfile Press Ctrl-C to interrupt Initial status (read from logfile) rescued: 0 B, errsize: 0 B, errors: 0 Current status rescued: 94368 MB, errsize: 0 B, current rate: 23068 kB/s ipos: 94368 MB, errors: 0, average rate: 28839 kB/s opos: 94368 MB, time from last successful read: 0 s Finished
ntfsresize -i -f datapartition says:
ntfsresize v2012.1.15AR.5 (libntfs-3g) Device name : datapartition NTFS volume version: 3.1 Cluster size : 4096 bytes Current volume size: 26999992832 bytes (27000 MB) Current device size: 94368605184 bytes (94369 MB) Checking filesystem consistency ... 100.00 percent completed Accounting clusters ... Space in use : 26107 MB (96.7%) Collecting resizing constraints ... You might resize at 26106810368 bytes or 26107 MB (freeing 893 MB). Please make a test run using both the -n and -s options before real resizing!
So it looks like I already resized the filesystem to fit the data, but did not resize the device? (This was 2 years ago, I forget.) And I need to resize the device using fdisk, right? But fdisk doesn't recognize the partition:
> fdisk -lu datapartition Disk datapartition: 94.4 GB, 94368605184 bytes 255 heads, 63 sectors/track, 11472 cylinders, total 184313682 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 identifier: 0x69205244 This doesn't look like a partition table Probably you selected the wrong device.

nor does cfdisk:
> cfdisk datapartition FATAL ERROR: Bad primary partition 1: Partition begins after end-of-disk Press any key to exit cfdisk
I can mount the partition and copy files off of it, though. How do I resize the device?
