in [Debian]

From: Germana Oliveira on 12 Mar 2010 12:30 Hi!! I have a pen drive and recently my debian can not find it because suddenly lose its format, so debian does not recognize it, don't even mount it. With dmesg it says the pen drive is in sda but #ls /dev/sda or /dev/sda1 does not exist in /dev ¿? How can i find my pen drive ???? so i can format it. Thanks!! -- Germana Oliveira germanaoliveirab arroba gmail punto com http://626f67.wordpress.com http://slcarabobo.wordpress.com

This really seems bizarre - you're saying that it shows up in dmesg as /dev/sda, but 'ls /dev/sda' shows 'No such file or directory' ?! Please report the *exact* dmesg and ls output here. > How can i find my pen drive ???? so i can format it. If you can't find it, you have worse problems than formatting. One thing at a time.

Maybe it's damaged or just died. How you tried to attach it into another computer? > With dmesg it says the pen drive is in sda but > #ls /dev/sda or /dev/sda1 > does not exist in /dev ¿? > > How can i find my pen drive ???? so i can format it. If the flash drive is not physically damaged but partition table is broken or lost, you can try with some recover data tools, such "TestDisk". http://www.cgsecurity.org/wiki/TestDisk Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
