Thread: New NTFS Disk Seems partitioned while it is not

i bought seagate barracuda 3tb disk replace older 2tb disk. copied data 2tb 1 new one. formatted disk ntfs first since want able use windows well. old was 99% full , 13,8 mb/sec transfer rate took on 40 hours copy data. after new disk worked under ubuntu, data fine. when restarted got error complaining missing mbr. weird, thought. switched sata cables ssd, containing dual-boot ubuntu-windows new disk. now, both ubuntu , windows start fine, new disk not mounted in of them. when load disk management both os show disk split in 6 parts:

• 3,14 gb unallocated
• 914,50 gb primary
• 13,74 gb unallocated
• 867,17 gb primary
• 249,45 gb unallocated
• 746,52 gb unallocated

edit: noticed disk looks different in ubuntu (the previous list in windows). ubuntu says this:

• 112 gb free space
• 871 gb ntfs partition 1
• 372 gb ntfs partition 2
• 1,6 tb free space

edit 2: when run fdisk -l shows new disk:

code:

disk /dev/sdc: 3000.6 gb, 3000592982016 bytes 255 heads, 63 sectors/track, 364801 cylinders, total 5860533168 sectors units = sectors of 1 * 512 = 512 bytes sector size (logical/physical): 512 bytes / 4096 bytes i/o size (minimum/optimal): 4096 bytes / 4096 bytes disk identifier: 0x2052474d  doesn't partition table selected wrong device.     device boot      start         end      blocks   id  system /dev/sdc1   ?     6579571  1924427647   958924038+  70  disksecure multi-boot partition 1 not start on physical sector boundary. /dev/sdc2   ?  1953251627  3771827541   909287957+  43  unknown partition 2 not start on physical sector boundary. /dev/sdc3   ?   225735265   225735274           5   72  unknown partition 3 not start on physical sector boundary. /dev/sdc4      2642411520  2642463409       25945    0  empty  partition table entries not in disk order

edit 3: found this post pretty exaclty describes problem. however, solution not provided. before give in , start on know how prevent these kind of problems in future

edit 4: this answer similar problem learned testdisk. when install can browse new disk without problems. need find way fix disk (with testdisk?)

there way disk working again? because don't want waste 40+ hours.

if 3tb drive cannot use fdisk nor mbr(msdos) partitioning.
need gpt(guid).
can use gparted, parted or gdisk fdisk gpt drives.

looks have data in partition table area of drive , partition tools trying read partition table.

did partition drive before copying data or format , copy data? have done , copy if large floppy drive not have partitions. every tool requires partition table correctly read drive.

gdisk say?
sudo apt-get install gdisk
sudo gdisk -l /dev/sdb
