Title: Pen drive not detected in 2.6.1
Post by: Onyarian on December 14, 2009, 03:07:57 PM

In all other releases mi 8Gb pen drive is detected as /dev/sdb and mounted in /mnt/sdb.

In this release 2.6.1 this pen drive is not detected, so I can't mount it. Other pens, per example, detected as /dev/sdc1 are mounted in /mnt/sdc1, but this sdb no, so finally I have to turn back to 2.6 version.

Is perhaps the updated rebuildfstab of 2.6.1?

What does fdisk -l show ?
What filesystem is on the pendrive that does not use a partition?
Be sure to test 2.7rc1 when it appears.

The pendrive is a LaCie 8Gb original formated with vfat.

The results with tc 2.6:

perhaps, as a solution,  it has to be newly formated, but it can happen with others too, and in the previous releases is well detected.

I will wait to test it with 2.7rc1.

Therein lies the problem, you do have psrtitions on the drive, but no filesystem can be detected in any of those partitions.

I have a similar problem - a usb device with no partitions.
mounting /dev/sda manually does work.


I guess the problem is in the device - but other systems (windows and linux) detect it.

Is there a way to modify rebuildfstab to detect such devices?

Unless you are running 2.6.1, you should start a new thread.
If you are running 2.6.1, you should update to 2.11.

Since 2.6.1, it relies on `fdisk -l` which requires partitions.
