Is there any possibility to use a SanDisk Ultra Fit USB 3.0 Flash Drive 64 GB work as Qu-Drive? The device is recognized by my Qu-16 but formatting doesn’t work (it gets stuck at 0%). I tried to set it up by computer by formatting it with FAT32 (32k cluster size) and creating the folder structure by hand, but that doesn’t work either.
Maybe it’s possible to support this drive in a future firmware release because it has a nice size…?
I bought one of those thinking because of its low profile it would sit nicely and not get knocked. I got no joy at all, same problem as you. It also ran very hot.
I rsorted to the Sandisk Extreme and that works fine. I have a Sandisk Cruzer that I might try as that is another low profile device, but I expect that won’t have the I/O performance that is needed.
UltraFit is the low profile one isn’t it?
Not sure what the sustained transfer speeds are - but it should format.
Did you plug it in before or after booting the QU? try the other???
Yes, it’s the tiny one: https://www.sandisk.com/products/usb/drives/ultra-fit3/
It doesn’t matter when I plug it in, before or after booting, the flash drive appears in Setup/Utility/Q-Drive but formatting doesn’t work :(.
Other people are having problems with the ultra-fit too
and here
I’ll have to try it in my car too, but completely useless for QU
It’s really annoying that the drive works perfectly on my Mac and other computers but not on my Qu-16. So perhaps it’s a problem with the Qu-16 and not with the drive itself?
Same issue here, I guess the power consumtion of the Ultra Fit is simply too high for the Qu socket.
That should be testable - get a USB cable with the power pins diverted to an off board supply (maybe just spliced in but with some protective diodes?)
No use for the “neat” case here, but would at least suggest a testable property of drives…
According to the information in the links provided above the “problem” would seem to be low write speed…
Go with the Extreme and if you need a lower profile use one of the right-angle USB pigtails.
Its not the write speed (the UltraFit does not even enumerate properly, communication lost right in the middle), and when a cable/right-angle is required, we’ll also could use the Extreme. Once you saw the UltraFit plugged into the Qu you really want this combination to work, but I doubt there’s a solution for existing units (just guessing!!!).
Check out the last post on this link - Sandisk have effectively acknowledged there is a problem!
And here are some other unflattering reviews
I have one for a readyNAS, so I appreciate the form factor.
The cable was only ever a test, givingnus concrete evidence of the issue.
I use an extreme on the end of a USB3 extension cable which is a right angle plug into the desk, pointing off to the side.
Andreas…
Can you shed any light on this?
When I use the Qu-drive to record a stereo backup copy of the audio feed I’m sending to video cameras I notice that Track 001 counts down from 4:00:00. If I then record Track 002 it again counts down from 4:00:00.
Why the 4 hour partitions?
Edit:
I’m using the Sandisk Extreme 16 GB sticks.
The 4h recording limit comes from the FAT32 filesystem which restricts filesize to 4GBytes each. Recording stereo with 24 Bit at 48kHz produces about a Gig per hour (24800036060). Multitrack recording limit is 8 hours per session, since 18 mono files are recorded.
Thank you.
Ok, just spliced a USB cable to do some power measurements. USB Power is not the issue with the Ultra Fit (64GB), it only draws about 100mA from the port. My external HDD has a peak consumption of about 700mA which is way above USB specs, but runs fine with the Qu. So the good info is, it looks like a software problem which should be possible to fix. I’ll redo some diagnostics on the USB side next days, maybe someone on A&H listens… 
We know something that isn’t the problem. yay
Maybe smaller versions of the Ultra Fit work?
Anyone who can confirm or test it?
From his last post Koksi01 is referring to a CruzerFit (USB2.0) and not an UltraFit (USB3.0). Would be indeed interesting to see multitrack recording on this rather slow stick (~4.5MB/s write speed as stated in some reviews)
Don’t you mean:
