comment SCSI's, SATA's, RAID's oh my. Please direct me the wizard of RAID recovery
When you connect the drives, what does blkid say about them?

comment What does `NO-CARRIER` and `DOWN` mean for a wireless interface?
I wouldn't think you would need explicit instructions that the meaning you already established for that flag didn't change to something completely different just because you're using a wireless adapter.

comment Optimizing logical sector size for physical sector size 4096 HDD
@Matan, I can't make sense out of your comment at all. I explained that IO is not performed 512 bytes at a time, so the fact that the disk is addressed in 512 byte sectors doesn't matter. The only time the drive has to do any emulating is if you try to do a write that is not 4k aligned, and since IO is normally done in multiples of 4k anyhow, and modern partitioning tools make sure the partition starts on a 4k boundary, that won't happen.

It means the same thing as it does for a wired interface: you're disconnected.

comment How to debug hard drive power saving?
@Dims, then you have something else that keeps touching the disks. You might use blktrace to find out what.

@Dims, hrm.. if you don't ever log into the gui, then no, I don't think udisks runs. Run ps aux and see if udisksd is running.

@goldilocks, APM is obsolete junk from the days before ACPI.

comment How does one inspect the directory structure information of a unix/linux file?
@Biff, a program would help certainly, but you can always do it manually with dd and a hex editor.

comment How does one inspect the directory structure information of a unix/linux file?
Yes; he said he knows the directory entry points to the inode, but he wants to see the actual directory entry rather than the contents of the inode.

That doesn't answer the question.

comment do processes access cpu and memory by system calls to the kernel?
The difference between a single threaded process and a multi-threaded one is only that all of the threads in a multi-threaded process share resources such as most of their ram and file handles. The scheduler doesn't differentiate between the two, so there are no special ways for threads within a multi-threaded process to choose how they are allocated cpu time beyond "normal" processes, which is to say, changing their priority and voluntarily sleeping.

comment Why my 3TB disk shows an actual size of ~800 GB with several tools except smart tools?
The disk is addressed in sectors, so the truncation isn't 40 bits vs. 44, but rather 36 bits vs. 32.

@user129107, hrm.. then there's some other kind of bug in your kernel. Try using a stock distribution kernel instead of a custom built one.

The problem isn't with fdisk or GPT; the kernel thinks the drive is only 800gb.

comment How to get over “device or resource busy”?
@foobarbecue, normally those are only advisory locks and the man page at least seems to indicate they are only for read/write, not unlink.
