issues with storage media

[Semih Ozlem]

Hi I ran into the following problems a few times.
As operating system I use debian 10 (.2 gnome) and ubuntu 18, 19, (recently
20).

Question 1 An external hard disk that I use (which is I think possibly
failing) was formatted in NTFS. While I was working on a machine at the
university where I used to work, all files disappeared, and reappeared and
the format of the disk was changed to FAT or something like that. I have no
idea why and how this happened. Does anyone have any clues

Question 2 I use usbs to store the files I work with. Quite a few times
when working with linux systems, the usbs refused to mount, giving wrong fs
type blaah blaah error. This was a usb that I used and stored files to
working under linux, and I do not remember the exact format on the disk. I
tried various programs to recover the files, and in some cases I was able
to recover some in other cases I was not able to. Sometimes I was able to
format the usb to be able to use it again, a few times I was unable to.
What methods are available to recover data, and what to do when something
like this happens.


Thank you in advance
