Thumbs down USB External HDD not recognize anymore on gentoo and BIOS


Hello

i dont know if its the right place to post my thread but instead of searching i have prefered to ask you some help.
Here is my problem : i have an Acer Aspire 9420 with gentoo installed and a 2.6.38-r3 kernel.
Since a few months i have decided to boot from an USB external HDD WD scorpio Blue 750go (with USB adapter) instead of the internal HDD.

Yesterday evening during my gnome session activity i had a black screen with a cursor and nothing can respond anymore.
I tried an hard reboot but my bios does not detect my USB Disk either.
So i boot from a liveDVD to check what is the problem and when i plug my usb disk here is what dmesg indicates
Code:
dmesg

I would say that if it's not recognized by bios you need to update them. I just worked on hp pavilion a1720n & it wouldn't reconize the dvd drive until I updated bios.
Check the usb drive out on another computer.

According to output of dmesg your drive is recognized and working. Have you tried to mount the partitions?

yet the partitions doesnt seem to be corrupted because when i tried to mount root & home partitions i have accessed to all the datas.

But the problem is when i turn on my laptop my usb disk is not recognized.

I doubt that the problem is related to bios because i use it since i boot from this external disk drive.

i dont have hdparm log here but it indicates that there is some address problem when it tries to do some test.
