NTFS partition RAW in windows but readable as NTFS in linux

#1 Post by rstancuna » 15 Apr 2016, 18:04

Have a 3.5 2TB USB3 external HDD with around 1.6TB full of data.
Was being used in a rack that broke, since i have an Asus K53S i can't connect it inside the laptop. Bought a Thermaltake Silver River III 5G external hard drive enclosure.

Out of nowhere, my Win10 sees the drive as unpartitioned space (looking in Disk Management) and it assigns a letter to it. Boot into PartedMagic 02-03-2016, same thing.
I used testdisk from PartedMagic, only did a quick scan and it found the NTFS partition containing all my files. Wrote the partition table, could mount and use all the files from my NTFS partition. Strange thing was that Gparted saw 8MB of unpartitioned space before my partition and 10MB of unpartitioned space after my partition. Check disk from Gparted didn't find anything wrong with my partition.
Boot into Win10, it sees the partition as RAW (looking into Disk Management), it assigns a letter to it and wants it formatted. Back into PartedMagic, the NTFS partition mounts and is usable.
Format the first 8MB into a partition with Gparted, get back in windows. Both partitions get letters assigned, the 8MB one can be open and used while the big one is still RAW and unusable. Go back to linux, use testdisk again, redo partition table, back in windows, same thing. I don't know why i tought this may work but worth a shot i guess.
Back in linux, delete that 8MB partition, move my 1.6TB partition to the start of the drive and it took around 5 days. Can mount and use the NTFS partition in linux, windows still sees it as RAW. Windows Check Disk wants to format the drive.
I need the drive to be usable in windows and i'm out of ideeas.

Tried Easeus Partition Recovery and MiniTool Partition Wizard as well, both just fail to find a partition and both just fail to find a partition and it's expected since the partition is not hidden but just not usable in windows.
I do not have another drive with enough storage to just copy the files and format this one so i'm looking for a way to make windows see the partition as NTFS and be usable there as it is in linux.

write!

write_all_log_i386: starting...
No extended partition
You will have to reboot for the change to take effect.

TestDisk exited normally.
TL;DR: Windows and Linux saw the drive as unpartitioned space, TestDisk fixed that and i was able to see it in linux as NTFS and mount/use it but windows it still sees the partition as RAW.

Under Windows, run "cmd" (right click run as administrator) and "chkdsk /f d:" (replace d: by the correct drive letter).

As i said, windows check disk wants to format the drive and this goes for both gui and command line check disk.

Can you post the chkdsk output ? I have already seen Windows Explorer asking if you want to format the disk or not, but never chkdsk.

Code: Select all

C:\Users\nkn>chkdsk /f E:
The type of the file system is RAW.
CHKDSK is not available for RAW drives.
Yes..not exacly that it wants to format it.
