comment File Operation not supported on Windows drives mounted on Ubuntu
Thanks. If I want to mount the drive with read and write, how to do it? By the way, I finally solved this problem, but not sure exactly how. My /windows-d has only about 500M left free. So I delete some files and got 1.2G free. At the same time I updated my system. After reboot, it works again.

comment Hardware Configuration Check on a New Laptop
Thanks John T! Yes it's design capacity is 56.16Wh. (1) do you mean 3 cells in series and another 3 cells in series and then the two groups parallel? (2) how do you calculate 56Wh from 4800mAh and 12.5V? (3) the current remaning capacity is 58.73Wh, does this mean my battery is overchanged?

comment Why am I not seeing all the partitions on my hard drive?
Thanks DaveM. Disk Management has three volumes: Lenovo_Recovery(Q:), SYSTEM_DRV and Windows7_OS(C:). All of three are simple layout, basic type and NTFS. SYSTEM_DRV, which is actually "Partition #0", has status as healthy (SYstem, Active, Primary Partition) and capacity as 1.17GB and 45% free. Lenovo_Recovery(Q:) is also healthy(Primary Partition). Windows7_OS(C:) is healthy (Boot, Page File, Crash Dump, Primary Partition). Although having list some info here, I still don't know what "Partition #0" or SYSTEM_DRV is for.

Thank you but I don't think so. Drive Q is already for Lenovo_Recovery, while I refer " Partition #0" as the missing one.

I have friends telling me Lenovo messed up with their ordered parts. Since I am not familiar with hardware, I think I had better to be careful.

comment Why is the effective hard drive size lower than the actual size?
Do you also mean the whole C: disk size does not include the size for MFT? Is there some place under Windows reporting the size of the whole hard drive?

comment How do I troubleshoot CPU temperatures in Ubuntu?
DigitalRoss, thank you so much! Some questions regarding your reply (1) I checked my /var/log/pm-*.log and syslog but did not find anything mentioned the crash down of my system yesterday. I guess perhaps the logging has not been enabled? (2) How to check ABit configuration? (3) How to check if the configuration file or BIOS settings are off and how to set them on? Thanks!

comment generate authentication key for ssh
Thanks again! I forgot to ask if I further need to generate authentication keys for ssh from Computer E to Computer B, how to prevent overwriting the files .ssh/authorized_keys2 on B for A to B? And if for another computer F to B?

comment %CPU for a process
@Doug: if you think what I am doing is not proper from the perspective of sharing and efficiency, please feel free to let me know. Are you using org-mode under emacs, something I heard last week?

comment %CPU for a process
Thanks Doug! Do you think that some processes are just getting less than 100 "%CPU" is because of me? BTW, what's the difference between SuperUSsr and SeverFault these two sites? Should I post my questions there?

The server has 16 cores. Load average is shown at the end of the first line. Are these what you asked?
