Thread: Seeing Hard Drives

i running ubuntu 12.04, 64 bit version, using gnone desktop.

having problem seeing other drives on system - internal sata drives , petitions or external usb drives.

around 50% of time when boot up, drives visible , mountable. however, other 50% of time drives not visible whatsoever on system (e.g. on desktop, in computer or in places), although show in gparted.

question is: how can drives show if don't appear on boot-up (other rebooting system , hoping best)?

thank you, in advance, assisatnce!

ralinux; hi !

oh // number of things; irq conflicts ? buss contention ? controllers confused or messed ... many many things.
ubuntu logs happens on system in log where. in attempt narrow things down.

code:

sudo cp /var/log/dmesg /var/log/dmesg-debug1

when system functional.
when system next has problems mounting external devices run code make file of current situation:

code:

sudo cp /var/log/dmesg /var/log/dmesg-debug2

[debug1 ->debug2].
compare 2 files differences. procedure may point nature of problem.

try'n help
