LMS on piCorePlayer with external hdd - can I sleep / spin down the hdd?

[rkrug]

Hi

I have a piCorePlayer which runs LMS. I have upgraded my external hdd to a LaCie Rugged 2TB, which holds the LMS database as well as the local music (two different partition). everything works fine.

This morning I realised, that the hdd did not spin down (which I think it did with the older hdd, but I am not sure). Is there a way of spinning the hdd down if it is not used for some minutes (20 minutes?) so that the hdd to reduce the wear of the hdd?

Thanks,

Rainer

There is no hard disk management in PCP. Some drives have software (windows/Mac) that you can use to program the drives controller.

Again, first check with the LaCie drive software..... If that doesn't allow you to change, you can try this.....let me know if it works.

ssh into your pCP device

tc@piTouch:~$ wget https://dl.dropboxusercontent.com/s/u9cqeo0gxjop8zj/hdparm
Connecting to dl.dropboxusercontent.com (162.125.6.6:443)
hdparm               100% |*************************************************************|   102k  0:00:00 ETA
tc@piTouch:~$ chmod 755 hdparm
tc@piTouch:~$ sudo ./hdparm -B 127 /dev/sd?  
tc@piTouch:~$ sudo ./hdparm -S 240 /dev/sd?

Obviously replace sd? with your drive letter. This should set your spindown at 20min, if the drive supports it.

I did - there does not seem to be any software from LaCie to shante these settings.

I have found the following info at

https://superuser.com/questions/9374...in-use-for-a-w

and will look at your suggestions.

I will report back.

Thanks,

Rainer

HD-idle also works well. There is a guide half way down this page.

OK - Installed it and set the parameter as suggested. Let’s see if it works (I did not get any error messages:

tc@LMS:~$ sudo ./hdparm -B 127 /dev/sdb

/dev/sdb:
setting Advanced Power Management level to 0x7f (127)
APM_level = 127
tc@LMS:~$ sudo ./hdparm -S 240 /dev/sdb

/dev/sdb:
setting standby to 240 (20 minutes)
tc@LMS:~$

Now the question, how can I mage this to be set again after a reboot - ore are the parameter stored in the hdd?

Thanks,

Rainer

The article that paul- linked to suggests a way to make it persist.
Look for "Persistent configuration using udev rule".
I don't know for sure that it will work with pCP (TinyCore) but should be easy to test.

[paul-]

The easiest way right is to make a little script, then call that script via the User Commands at the bottom of the tweaks page.

I noticed you referenced /dev/sdb. If you have more than one USB drive, it may change drive letters at the next reboot.

Hello, I used the download link and the instructions, and it is really fine !

I hope that this feature will find its way as an official extension to the system.

Thanks for all and best regards,

JMF
