Hi,

I am noting a new issues for the last two days. Some times my system goes slow and all I hear is HDD noise as if its trying to access data. The entire PC almost hangs and have to do a hard reboot.

Just for update. I downloaded WD's Smart for Windows and ran the test. Everything showed fine.

A comment about this. I bought a pair of WD drives for my wife's computer and installed oS on them (11.3 with the system on one drive and the second used for backups). While oS installed OK when I went to boot it after the installation - nothing happened because there was no operating system installed!

To cut a long story short, I downloaded the WD test disc and ran it against both new drives. Each one was perfect. But no matter how many times I re-installed oS on the original configuration of these drives (ie, drive 1 as :master" and drive 2 as "slave" got the same result: no operating system installed. I then swapped the drives around - 2 as "master", 1 as "slave" - and lo and behold all was well: oS was booting. The bottom line was that drive was for some reason simply would not 'work' with an operating system on it; but is now working perfectly and happily as a 'slave'. Go figure.....

Hi My ASUS Motherboard in the desktop is like that, on the MB the SATA ports are labeled 1-4 but plug in a couple of drives and linux recognizes the controller numbers in reverse order.... so sda exists in the BIOS as drive 4... was really confused as I use three drives all the same.... -- Cheers Malcolm °¿° (Linux Counter #276890) openSUSE 12.1 (x86_64) Kernel 3.1.0-1.2-desktop up 0:26, 3 users, load average: 0.84, 0.81, 0.70 CPU Intel i5 CPU M520@2.40GHz | Intel Arrandale GPU -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I believe which drive is assigned /dev/sda depends on what order they are detected by the kernel. In theory that can change over time - i.e. be different on different boots or after a kernel upgrade or as the disks age or perhaps the phase of the moon. I have one machine where the disks are detected in different orders by the particular versions of ubuntu and opensuse kernels on that machine, for example. So use some other method to identify disks. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
