Is it possible to mount an USB pendrive in a slower or safe mode?

bohokash · 2021-03-20 16:22:10

My thumb drive has some problems: it is periodically unmounted, and then remounted. When I try to copy the files, the process halts or stalls after a few hundred megabytes are transferred.

Is it possible somehow to use it some other way, in a slower mode, which is safe, and saving the data from it?

As far as I remember this thumb drive had the same exact behaviour about two years ago, but I was able to revive it with a program from the manufacturer (Transcend). After that I was able to use it properly, either reading, writing for about 2 years. The problem was that the program was usable only in Windows. Unfortunately I don't have Windows any more. I had to install Windows 7 at that time, as Windows versions capable of running from DVD wasn't able to run the special program from the manufacturer.

Let's start with "how do you mount it right now"?
Because drives don't just unmount and automatically re-mount.
An automounter might mount it when the drive registers, and systemd can mount drives when the mountpoint is accessed and also unmount them on idle, but the way you describe it sounds more as if the device unregisters from the bus, ie. doesn't unmount and esp. doesn't sync, ie. you're most likely gonna face some data loss.
That'd not be a mount thing, but a flaky connection and that's either because of a loose connection/plug or some usb issues.

So elaborate on the status quo and provide a dmesg that covers a "remounting" sequence.

Interestingly I was able to connect the thumb drive to my Wifi router USB interface, but ony through an USB 2.0 HUB / Ethernet combo. When I omit the USB HUB, it isn't recognized. Then I am able to share and copy the content by FTP right now.

I can see these related events in the dmesg output:
