comment Emulate 512-byte sectors with Xen
AFAIK, xen always emulates a 512 byte sector disk.

comment What is filling up my C drive?
Your company's IT department should have reimaged the machine before issuing it to a new person. Go kick them and let them fix it.

comment PC stuck in BIOS with 4 TB harddrive
That's odd... I've plugged in drives on the fly in linux and in windows back when I ran it. Just had to force a scan for the disk to show up ( this was with ide disks, sata controllers now usually have hotplug support so they show up automatically ).

comment PC stuck in BIOS with 4 TB harddrive
It sounds like your bios thinks otherwise. Make sure it's set to boot from the other drive rather than trying the 4tb one first.

comment 1000 Mbit/s Connection but WLAN only gets 54 Mbit/s
Well, the real improvement is the mimo + 40 MHz channels. The beam forming also helps improve real performance, rather than maximum theoretical under ideal conditions ( very close range ). Also iirc, you only get the 65 Mbps rate if you disable compatibility with 802.11b/g, so typically you're still only going to see 54 Mbps in the 2.4 GHz band.

Boot from the Windows install/recovery disc and use the recovery console command "fixmbr" and "fixboot"

comment 1000 Mbit/s Connection but WLAN only gets 54 Mbit/s
@DanielB, no, 150 MBps is the 40 MHz channel rate, which normally isn't used in the 2.4 GHz band since that is pretty much the entire band.

@DanielB, sure but MIMO requires dual antennae.

@AFH, no, you can't since gparted only operates on disks that are already partitioned.

comment Very Slow Charging: Thinkpad X60
Is the system running very hot? If the temperature gets too high that can cause the battery to stop charging.

Your computer/phone/tablet doesn't support 802.11ac? 54 Mbps is the limit of 802.11g and 802.11n, in the 2.4 GHz band.

comment Very Slow Charging: Thinkpad X60
Doesn't look like it. The output from upower looks perfectly normal, though it will take 6 hours to charge. Typically the laptop has a stated maximum draw from the DC input so if you are running it and using power for that, there will be less power available to charge the battery.

comment 2 slot external hard drive dock with 1 eSATA connection?
@ChristopherBruce, nifty.. I got an esata bracket so I can connect the dock to my internal ports and found that the JMicron controller is just slow due to it being connected at only pcie 1x gen 1 speed, and the Intel and Marvell controllers are each capable of 270 and 240 MB/s respectively. I had to patch the kernel to disable fbs on the Marvell because it didn't work at all, giving 106 MB/s sustained to each drive simultaneously.

comment Can 4 sticks of memory reduce CPU life?
If you use only two sticks, do they run at the rated speed? ( without error? )

comment What's the Bash equivalent of “cmd /c”
To expand on that: the reason this works with cmd is that it has hacks to detect that the application being started is a gui one and fake the return code rather than waiting for the process to actually terminate and return a status.

comment 2 slot external hard drive dock with 1 eSATA connection?
@ChristopherBruce, posting this answer drove me to dig back into investigating the performance issue again and it seems I may have jumped to conclusions about the fis based switching and the problem may simply be that the JMicron controller that drives my eSATA ports just sucks; it appears to simply have a maximum throughput of only ~170 MB/s even to a single drive when reading entirely out of the drive cache rather than the platters, which is more like ~270 MB/s when I connect the drive to my internal controller. I'm going to order an esata adapter board for my other controllers and test.

comment Rewriting partition table to be BIOS/DOS compatible
@Synetech, the incorrect relative sectors ( another foolish thing Microsoft decided to encode in their boot sectors ) will also prevent it from booting. You should be able to use fixboot from another system's recovery console on the problem disk just fine.
