My FW 800 G-RAID2 Became Slower?
System: FCS 6.05 on MBPRO, FW800 G-RAID2, expresscard Nitro FW additional bus.
Project: 720p24 DVCPROHD 60-minute doc.I just prepared a G-RAID for this long edit by slimming down its total contents to less than 50% of capacity (as per thread: https://forums.creativecow.net/thread/8/1026220).
Repaired permissions on Mac. Reconnected all files fine.Problem: media drive behaving somewhat slower now, via internal or additional FW bus.
Scrubbing and playback delayed and stuttery compared to before rebuilding media drive contents.What might it be?

If you just deleted stuff without erasing/reformatting, you are probably seeing the results of file fragmentation.

I backed up all media, then totally Erased using Disk Utility, with Mac OS Extended format. Then opened FCS and chose the freshly wiped drive as a scratch location, copied the appropriate project’s capture scratch folder into the newly created main Capture Scratch folder.
All 1,300 clips connected just fine. Project opened no problem. Only difference before and after is the clip response time dragging its heels a bit. Just enough to add precious hours to a 3-week edit!

Run Disk Warrior on the drive.

Thanks for advice… I should run Disk Warrior on the MBPRO system drive, or the external? I have yet to buy the app, on their website descriptions seem targeted to the internal.

You should get it, and run it on all drives. CalDigit even recommends running it on their Raid 5 systems.

And here I am with my friend David to promote the use of any of the applications that rebuild the HDs directories.
I feel my self some times like a stupid repeating to the people to optimize the System.
An application to do that is indispensable for anybody who runs a Mac.
Next time run the AJA System Test application (free) before and after running DiskWarrior, TechToos or whatever the application you use. You will see in numbers how the clean directories boots the speed of your drives.

Resolution:
Thanks gentlemen for the DiskWarrior advice; I bought and ran it on all drives and it is now an important part of the editorial toolset.

“Gentlemen? I think you give Rafael and myself far too much credit. We’re just regular guys who just like to get our work out the door.
Glad it DW did the trick…

DW seemed to help, at first. Then the G-RAID2 drive got slower and slower and made some crunching sounds, and slowed to a crawl.
Finally it couldn’t perform at all. Called G-Tech support, and after restarting the Mac the drive wouldn’t mount at all, yet even unmounted made lots more crunching noise like it was calculating climate change. They told me it was toast and ship it in for repair/replace.
That settled, I took one of my other G-RAID2 units, backed up its media, formatted it as per G-Tech spec, ran DW for fun, and started to load it up with the current job’s media from a b/u storage drive.
And… after a 100GB or so it got slower, and slower… Ran DW a couple of times more. But it ran even slower, loud crunching sounds, and slower…This was a totally different G-RAID2 bought a year before the failed one, so– huh?
Tried swapping out everything– FW cables, internal FW bus vs. Nitro card FW bus on the MBPRO, tried another Mac. Nothing.Then I tried another power supply. The simmering hot black transformer that came with one of my G-RAID2 units– I was using the same one for both drives since I usually mount just one at a time. Another power supply, and the drive resumed normal performance.
When all this job’s media is re-loaded I’ll try and edit, but so far the data transfer rate and drive behavior seem fine.
The danged power supply? I’d have guessed a bad transformer would stop the drive from working, period, or turn it abruptly on and off. But actually slow it down while it stays mounted on the desktop? Never would’ve guessed, and neither did the G-Tech support guy.
