so far i haven't done anything.
my drives depend on controllers ability to enable or disable write cach.
so if the external sata drive i have is connected via usb i can disable write cache. if it is connected via sata cable, then NO option of setting for fast removal.
not found anything yet about tools.

ok. i did it. the solution of disabling write caching on sillicon image 3112 onboard controller was to use the windows utility given in the ic7g cdrom.
even if the drives show the options greyed out, the setting is done from the sata utility and it is shown set in properties of the controller for each drive.
thanks for help.


now i want to disable look ahead.
how can i do it?

you want to disable read cache? I don't think it's a good idea to do that. Most drives really need it to function properly. They load the geometry of the drive to have it ready. If you turn off, all movements have to be done from scratch, instead of looking up in the cached tables. You can easily kill the performance of a drive that way. No, please don't do it.

What's the point in turning off all these buffers? In the old days the innefficiencies of the 16bit windows versions (win98 etc) combined with the extremely slow nature of the hardware might have offered an advantage, but I'm not sure I understand where it's useful on a modern system aside from certain realtime considerations (financial data etc where you can't afford to lose the buffered data in event of a crash)?

according to creamwares suggestions.

i can undestand though that they refer to older machines.

i thought i could make my audio drive just a surface of receiving recorded data. like tape recorder.

i guess i am wrong since the whole rec process in a software sequencer is loaded in ram first. isn't that right? and i have to save after.

recordings are done on your harddisk ('harddisk recording').
once a recording is done you have it, even a crash happens after it.
only you have to import the file after restart.
changes in sequencer data like midi, arrangement etc are stored in RAM and will be lost, unless the operating system has a total recovery provision (Mac OSX has it, if I'm right).

recording on the soft sequencer never holds the data recorded unless saving or auto saving. but without saving if a pc freezes or sequencer stucks, all of the recorded material disapears.

in fact that was my intention trying to avoid caching generally(hd cache or other memory cach), just to make the hard drives similar to what a tape recording system is. which means no problem to the already recorded sounds nomater what stops the rec process.

Don't know about other seqs, but Logic has always seemed to write each raw audio recording take to disk independently of the song file - I've had crashes but didn't lose audio files...

Arcadios - no offence here, but if your system is working okay, then you should probably just get some work done instead of messing with the system. If you're having problems, then I'd advise to look at the hardware you've got and get better components if necessary - it's cheaper in the long run than wasting time tinkering with things that are really only going to make things worse unless you really know what you're doing and what to look for.

If you have decent components (especially the motherboard), then you should be able to get a stable system with virtually no tweaking (just basic stuff like setting XP to prioritize background processes etc).

yea darkrezin i agree, most of all i am a classical musician(singer), all these years i work without even mics on stage and with mics on recording. in studios at greek national radio orchestras and choir the recording process is almost always on 2" tapes. i don't wanna compare these high end equipment with mine, but at least i try to get the best from my machines not for just having them but for using them as well.
what you told me about logic is something i didn't know. nuendo looses everything if you stop the prog without saving.


to be honest,
i am not very satisfied from pcs.

digital recording requires different techniques than 2" tape. tape requires the levels to be high all the time and then compression takes place. digital requires the levels be moderate(to avoid clipping) and compression must be added after.

both sound good. i dumped a 2" scully after my daw became functional and i haven't looked back. i've done way more music since. the tape machine is a wonderful device, but it's constant maintanance and tape is no longer made......

your pc should almost never, ever crash. perhaps too much fiddling with it has made it unstable?....

There are also so many diferences between the way a a PC works as a recorder and a multitrack tape machine that seeking to make the PC 'work the same way' is possibly going to create problems. Modern OS's are designed to work with many layers of data moving about, buffering is a part of this. The 2 biggest concerns should be keeping buffers from emptying (causing digital 'glitching' from data dropout) and keeping the overall machine stable to avoid crashing.

If you're still worried about losing something in the recording process I would suggest u keep a b-roll of some sort rolling (DAT, ADAT, an old 2-track, unused multitrack recorder in the corner, etc). For many work flows this can sometimes prove an invaluable way to recapture something that occured while your sequencer may not have even been running yet.

also, tape machines lose data all the time! nothing is for sure in this life.
