KI Pro stops record with 10% left
-
If you are on Snow Leopard, 250GBs is 250GBs due to the base10 count.
So less 10% that would be 225 Gigs.

[Michael Craven] “Copy that, but either way I’d like to know what the actual recording capacity of the drive is with the 10% buffer. I guess I could just figure it at 200GB to be sa”
Good idea and that is about the number I use
at minimum at least 10% of the space is taken up by the directory and that structure varies depending on how many, and what types of files are on the drive.
My rule for ALL hard disk drives is to never fill them to more that 80%, so that 200G volume level is almost exactly what I go for. This is as much a performance issue as it is a “health and safety” issue.

“ah, the KiPro is NOT running Snow Leopard, and since it formats drives based on its own operating system, that would be a bad idea, since that number {225GB} does not take any of the hardware related file structure and directories into account which reduce that available amount of space even farther.
These are all hard drive/ scratch disk basic issues. The reality of how hard dives work and function does not change because that drive is no longer attached to your mac. These drives follow the same rules as those on your edit system do.
You should NEVER fill a hard drive or drives to more than 80% of the listed volume size !!!NEVER!!! This can cause directory structure errors and temp file failures as the files are written over in attempt to handle the excess data.
Not to mention that virtually all disk drives slow in read/ write speed as the drive gets closer to the maximum amount of data it can hold.gary adcock

[gary adcock] “ah, the KiPro is NOT running Snow Leopard”
What, you’re sh*tting me? 😉
Still, when plugging the drive in to Snow Leopard, it still shows up as 250GBs. I don’t see why you can’t just look at the front of the Ki. It’s so much less math. 😛

JA and GA is correct.
Just by chance i have been specialized in video storage and i also have KiPro 😉
A drive whether a single drive or RAID storage will drop performance when the capacity hit 80 %. In this case I am more conservative than Gary, i make a rule my self for 70 % , in order to eliminate problems, mainly for those who works with HD material.
The way KiPro record to the drive is the same like you capture video to FCP storage. When there is no sufficient bandwith available it just can not capture or drop frame. With KiPro, it can not record.
Other reason to have 70 % with KiPro is that, sometimes ( when in a rush) customers do directly edit on field with the macbook pro. Having 30 % empty space of the Ki storage connected to MBPro via FW800 will allow them to work without drop frame issue . I can not i imagine if it only has 10 % empty space.

Same here, and Its no secret that I have a couple KiPro’s too.
“i make a rule my self for 70 % , in order to eliminate problems, mainly for those who works with HD material.”
IMHO that would depend on the type of drive, IDE definitely, however I am comfortable with the current generations of SATA drives- so that i feel my number (80% capacity) is acceptable for the vast majority of drive users, not just for those working from the KiPro’s drive modules.
What we do not mention is that not all drives are equal. That $99/88€ hard drive are as much a commodity on the market as coffemakers and toasters. One should not expect the same the same from a Yugo as they would a Mercedes-Benz, and I believe that hard drives are no different. What other device do we work with daily that comes with a failure rating as part of the specs? ( MTBF = mean time between failure).

To answer the question posted earlier, it actually is quite close to 10% when it stops. We have the 500GB Drive, and it stopped with 52.4 GB left on it. We actually didn’t know it was going to do that, and we were recording a live event. Oh well, now we know.
