how to read NTFS disk
 

I have a disk that had some problems now reading in Windows and is formated NTFS. I put it in my Linux Debian 8 computer but it won't read it either. When using the Disk application it shows there are 3 NTFS partitions (PQService, System Reserved and Acer) plus a free space of 2 Mb. I selected the 3rd partion of 750 Gb then clicked to mount but got error message: not authorized to perform operation (udisks-error-quark, 3). All I want is to read the disk so I can retrieve and backup the files from it. Any simple way to do it?

/etc/fstab?

If Windows has trouble reading a Windows proprietary filesystem, why would you expect Linux to do any better ?.

Issue a mount command as sudo/root - that way you'll get to see any messages issued rather than a GUI obfuscating things. This presumes you have ntfs-3g installed - does Debian allow that ?.

how to mount an NTFS for reading? it is listed as /dev/sdb3

see info fstab or info mount! (on console)

For reading only

mount -t ntfs-3g /dev/sdax

mounts the partition with read/write access.

No gui in Debian?

Ntfs mount is built into kernel to read. May not even need to add ntfs info on mount but can't hurt. Mount usually knows, ntfs-3g option should allow you to write.
