ZhoubaWiki:HowToCloneHddWin10ToSSD

2023-05-31T19:43:24Z

Garak: /* How to clone a HDD w/ Win10 to an SSD */

== How to clone an HDD w/ Win10 to an SSD ==

'''First'''

<code>
dd id=/dev/source of=/dev/target bs=64K conv=sync,noerror status=progress
</code>

'''Then'''

<code>
ntfsfix /dev/target
</code>

Finally boot the target system using the freshly cloned disk

Usually auto-repair or something similar is triggered on first Win10 run from the clone-target device, also some reboots. But generally it works. The last time I did it it behaved like this:

# Booted, Win logo, some message about running auto-repair, spinner spinning
# Reboot
# Booted, Win logo, spinner spinning indefinitely (no CPU or disk utilization)
# ''Manual power-cycle executed''
# Booted, Win logo, auto disk-check w/ options: do-scan or skip
# ''Do scan selected''
# Text GUI showing check progress
# Reboot
# Booted, Win logo, booted successful to the login screen

ZhoubaWiki:Bc-cpu-benchl

Garak: /* Bc as CPU benchmark for multicore cpu */

== Bc as CPU benchmark for multicore cpu ==

Referring to this http://tuxshell.blogspot.com/2009/08/bc-as-cpu-benchmark.html post, I figured out the simple way how to test speed of multicore cpu system or multi cpu system. This command:
<pre>
$ time echo "scale=5000; a(1)*4" | bc -l
</pre>
will only be executed on one CPU core. However we can use GNU parallel command to execute it many times on multicore cpu. First we create benchmark script b.sh as follows:
<pre>
#!/bin/bash
echo "scale=$1; a(1)*4" | bc -l
</pre>
The first argument is number of digits to calculate. Now we can run in parallel (4 times) this way
<pre>
$ time parallel ./b.sh ::: 2000 2000 2000 2000
</pre>
We can determine the number of cores with this command:
<pre>
$ cat /proc/cpuinfo | grep processor | wc -l
4
</pre>
If your cpu supports hyper threading - this will give you the number of logical cores, not only the physical ones

'''Gateway in Budweis - gw'''

It is actually 2 routers in one box:-)

== Configuration ==

[https://www.cpu-world.com/CPUs/K8/AMD-Athlon%2064%20X2%205000+%20-%20ADO5000IAA5DO%20(ADO5000DOBOX).html AMD Athlon 64 X2 5000+] 2.6 GHz (2C2T)@[https://www.msi.com/Motherboard/K9A_Platinum K9A Platinum]

1GiB DDR2 533MHz RAM memory (2x 512MiB in dual-channel; not that it would make any difference if it weren't; also 100MiB would be plenty for the purpose)

2GB SSD (actually an SD card in microSD<->IDE adapter)

* No GPU
* No HDD
* Semi-passive CPU cooling (passive under 55C core temp)

=== NICs ===
# RTL-8111B PCI Express Gigabit Ethernet Controller (onboard, WAN 1Gbps)
# RTL-8110SC Gigabit Ethernet (onboard, LAN 1Gbps)
# RTL-8139 PCI Fast Ethernet Adapter (AIC, LAN 100Mbps for wireless AP)

== Features ==
* Running Debian 8
* PPTP VPN pass-through
* kernel parameters tuned up for routing performance and minimal latency
* ingress firewall setup

== TODOs ==
* <s>Apparently forgot to enable AMD Cool’n’Quiet in BIOS after CMOS battery dropped dead</s> Enabled it now.
* Downgrade and undervolt CPU (have one nice 4000+ handy)
* Embed wireless module. Got one nice Microtic routerboard for 5G 802.11n. I imagine it being inside the box, so it would involve some cutting for the signal not to be shielded out.
