How vibration sensitive are hard disk drives?


I've gotten my hands on a seriously cheap laptop grade 2.5 inch drive. I'm intending to use one on a desktop that doesn't have 2.5 inch bays as a boot drive. While I know there are adapters available, I know its fairly common with SSDs to simply velcro/tape the drive somewhere. I'm wondering if I can do the same with a laptop hard drive.


One issue I see here is SSDs are fairly insensitive to vibration, while hard drives are. Just how vibration sensitive are drives? Would a jerry rigged mount need to take this into account?



Answer



Laptop drives are generally more vibration-resistant than desktop drives (they are designed to be used in a moving plane, car, in a laptop on someone's laps, etc.), so from this standpoint there shouldn't be a problem taping them somewhere inside your computer's case. There are other problems, however:




  • When hard drive is fastened properly, metal bracket also acts as a heatsink. Moreover, in a properly designed case there should be an airflow around a hard drive. Your tape will have lower thermal conductivity than metal, and depending where you tape it, there could be less airflow available. So your hard drive could overheat.




  • Constant vibration (from hard drive's motor, computer's fans, etc.) can loosen the tape over time, depending what kind of a tape you use, it can dry up, etc. So don't put your hard drive vertically somewhere, make sure it's fairly secure without the tape, and use the tape as an additional measure, not as something that prevents your hard drive from falling down on your motherboard, for example.




  • Make sure you don't short anything on hard drive's PCB, if it is exposed (e.g. there are no protruding screw heads on the surface that you tape your hard drive to).




I've used tape to secure 2.5" hard drives in a desktop tapes, but only temporarily (till I got around to order a few of those conversion brackets).

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
