[Solved] Not write folders and files in partition NTFS (problem after restart) / Problem with memory cache SSD

[Cristian Aravena Romero]

Hello!

1) I'm writing files/folders in partition /dev/sda6 (my-doc); /dev/sda2 (win7) , and create folders and files :)
2) Reboot
3) Start Win7
4) Partition my-doc and win7 with old file/folders. Not saving files/folders in point "1)"

The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.

1) Please post the formatting parameters of sda2 and sda6 :
sudo ntfsinfo -fm /dev/sda2
sudo ntfsinfo -fm /dev/sda6
2) Are the files created on Win7 shown by Linux ?

Yes.

[Jean-Pierre (jean-pierre-andre)]

Do you use some special hardware (such as a cache on SSD) ?

To discriminate "Linux does not write the data" from "Windows does not get the data", please try the following (on sda6, to avoid putting Windows at risk) :
1) Boot on Linux and create some file.
2) Reboot on Linux (without starting Windows in-between).
3) Still on Linux, check whether you can access the file created at step 1.

Note : your formatting parameters appear to be valid, though suboptimal on a 4K-sector disk.

Yes, I use a SSD cache memory

What should I do to be optimal?

[Jean-Pierre (jean-pierre-andre)]

"Yes, I use a SSD cache memory"
Windows and Linux do not use compatible cacheing. On a dual-boot computer, you have to disable the cacheing altogether. See for instance http://useranswer.com/answer/dual-boot-installation-of-ubuntu-12-04-lts-on-hp-ultrabook-envy-4-1002tx/ However this is a risky operation, do a full backup before trying.

"What should I do to be optimal?"
You should format your partitions for 4K sectors. As your primary and logical partitions start on a sector boundary, you need not repartition. On sda6 you have no data, so reformating is easy :

sudo mkntfs -f -L mis-doc -s4096 -c4096 /dev/sda6

Thanks Jean-Pierre!

[Cristian Aravena Romero (caravena)]

Now work fine (Cache SSD disable)

[Cristian Aravena Romero (caravena)]

I'ts not bug.
