ParticipantI am new to Cymatic and the uTrack24. When I have a USB drive connected to my brand new uTrack24 it disables the USB interface mode. Is this by design? I don’t see anything in the manual.
How can one transfer files from a PC or a Mac to the uTrack24 if the drive is not accessible when in USB Interface mode?
NOTE: After formatting my USB drive with my uTrack24 it is no longer readable by my PC Is this also by design? So with a drive I can only access using the uTrack24 and the inability to be in USB interface mode and have a drive connected to the uTrack24 I’m a bit lost as to how to transfer files.
I am running the latest firmware 4218
Any help is appreciated.

10th November 2018 at 05:34 #43010ParticipantHi,
I want to use the uTrack24 as a live playback device (play to track). I already have multi track recordings (recorded in Pro Tools). I need to transfer, or add, or somehow get the individual tracks into the uTrack24 for play live on stage. Is this possible? Anytime I am connected to my Mac and then plug a drive into the uTrack’s front panel usb I lose connection to my Mac.
The intent is to take bass, keyboard, and other tracks I have already recorded (in Pro Tools) and have those play back in multi track mode from the uTrack so we’ll have individual control of each backing track live. (I hope that makes sense).
Any help is appreciated
10th November 2018 at 17:53 #43017ParticipantUPDATE: I was able to finally get my drive to be recognized by both my Mac and PC after formatting the drive with the uTrack24 a 2nd time HOWEVER, it only formats the first 2 TB leaving the remaining 2 TB unused.
The manual says the uTrack24 supports up to 16TB so I’m unclear why it’s only formatting the first 2TB

KeymasterHi Bob,
Yes the uTrack24 does support USB drives up to 16TB.
Do I understand that your USB drive is a 4TB drive? The uTrack24 during the format process takes the first partition from the USB drive. So if your USB drive previously had two partition, you need to make only one partition on the drive (using the disk utility tool on your computer) then reformat the drive with uTrack24.
Create content and transfer it to the the USB drive you’ll need to use uTool.14th November 2018 at 16:49 #43107ParticipantHi Laszlo,
Thanks for the reply
I can try to reformat the drive on my PC using the disk management system and ensure it’s a single partition. But just to be clear this was a BRAND NEW DRIVE that I purchased solely for this purpose.
When I pulled it out of the box, my PC did see that it was a single partition 4 TB Drive (and so did my Mac). Without doing anything to the drive (other than connecting it to my computers to verify it was functional), I plugged it into the uTrack24. The uTrack24 came up with a message that the formatting was unsupported and would I like to format the Drive. I said yes which landed me where I am today. Any additional Guidance would be appreciated.
I’ll try to reformat the drive on my PC as a single Partition drive and start over.
14th November 2018 at 23:58 #43115ParticipantHi Laszlo,
I deleted all partitions and created a single partition (I don’t thunk there were 2 partitions just unallocated space)
I formatted the drive using NTFS (Windows 10 no longer allowed you to format using FAT32)
I connected drive to uTrack24, it reported the unsupported file system and asked to reformat the drive. After reformatting I connect the drive to my Windows 10 PC and it reports a 2 TB drive with 2TB of unallocated space (see before and after screen shots below)
Any assistance is appreciated.
Thanks,
Bob

We are using MBR and the GPT not supported under uTrack24.
If your drive is an USB drive which is uses 512 bytes per sector in this case the maximum partition size using FAT32 is limited to 2TB.
As I see correctly this problem can happens mostly on the 4TB drives, because if the drive bigger most likely it will uses 4096 bytes per sector, which makes 16TB limitation.
The 4096 byte per sector is a very common feature with modern drives.15th November 2018 at 15:46 #43126ParticipantThanks Again Laszlo.
So if I format the drive (outside of the uTrack24) using FAT32 and GPT so I see all 4 TB in FAT32 (on a computer)…..will the uTrack24 see all 4TBs? Will it force me to re-format using the uTracks format option?
This seems like this is the only way possible you can claim the uTrack 24 supports drives up to 16TB. If not, it seems the reality is the uTrack24 (limited by MBR) would only support up to 2 TB.
Had I know that I would have saved a few bucks and when with a 2 TB drive (and probably saved myself a bunch of time while I was at it). Drives are pretty cheap nowadays, but the only reason I got the larger drive was based on the specs provided.
16th November 2018 at 07:31 #43138KeymasterThe uTrack24 compatible only with MBR, so once you connect the drive with GPT it will ask you to reformat the drive.
The problem is the following:
Some 3-4 TB drives are using 512 bytes per sector those drives can be formatted only 2TB
Most of the drives which is bigger than 4TB are using 4096bytes per sector, those drives are limited to 16TB.
“the sector size was increased by the factor of eight, from 512 bytes to 4096 bytes, pushing the MBR address space up to 16 TB.”Had I know that I would have saved a few bucks and when with a 2 TB drive (and probably saved myself a bunch of time while I was at it). Drives are pretty cheap nowadays, but the only reason I got the larger drive was based on the specs provided.
I’m sorry about that. To be honest we didn’t discovered this issue before. Since you have reported this issue we have made an investigation, and we have discovered that limitation with some USB drives because of the physical construction of the USB drive.
16th November 2018 at 17:11 #43150ParticipantLaszlo,
No Apology necessary.
Thanks for the detailed explanation. Now I clearly understand the issue. My assumption was this would be for all Drives larger than 2 TB. Now that I know, my next drive will be larger than 4 TB and I’ll be on the lookout for the sector size.
For what it’s worth, I’m loving me new uTrack24!
Thanks for all your help and fast responses.
Bob
