enli Posted December 9, 2008 Share Posted December 9, 2008 Hi, I was wondering if we can somehow disable write caching for SATA. We have frequent power-cuts here and I am not always at desk to turn-off Desktop before UPS dies. If I understand correct, enabling disk caching increases the data-loss possibility when there is a power-cut. Any help?

hecker Posted December 9, 2008 Share Posted December 9, 2008 Hmm, I had no idea that OS X had an option for that. I'll check. Link to comment https://www.insanelymac.com/forum/topic/140124-how-do-i-disable-write-caching-on-sata/#findComment-992504 Share on other sites More sharing options...

gawkersucks Posted December 11, 2008 Share Posted December 11, 2008 If your UPS is connected (data) to the PC then you can schedule a shutdown based on battery percentage or time on battery power.

enli Posted December 11, 2008 Author Share Posted December 11, 2008 Thanks Chrisb27, that is interesting. The problem is that currently the UPS i have is dieing instantly when there is a power-cut. I guess i will have to repair it but i dont have enough money right now ( yes I am a student ). And how does the mac read ups stats? Using RS-232 interface?

ttxxx Posted December 11, 2008 Share Posted December 11, 2008 You should get something like this (http://www.apcc.com/resource/include/techspec_index.cfm?base_sku=SUA1500) This vendor obvious does Mac and model like this have USB interface (is that the same one Chrisb27's using?) Also seems that this company is the most expensive so I think it won't fit your budget. (have a looking at their website, some entry model may cost $60-70 or something) And anyway if your computer would shutdown instantly with your current UPS, you may get the batteries replaced, or it would just become a surge protector. Luckily I am living in a city where no surge would appear as the power is delivered through underground cables.

bing Posted December 14, 2008 Share Posted December 14, 2008 Maybe this? http://www.macupdate.com/info.php/id/9503/...d-cache-cleaner I haven't looked at it to see if it does what you'd like but if it does, maybe it's cron'able. Based on a few of the comments I read I'd b careful using it for functions I don't fully understand.

enli Posted December 15, 2008 Author Share Posted December 15, 2008 As the name suggests its a cache cleaner. I need a program to disable write caching on selected disk.

bing Posted December 15, 2008 Share Posted December 15, 2008 Well, on the screenshot I see options for "Optimize File Caching" and "File System Journaling." Did you check it out? I didn't see much at all in a cursory search for HFS+ tuning, hope that helps.
