Rec to SSD fails with an explanation mark

PostTue Nov 23, 2021 4:09 pm

Ive recently added the mini recorder to my BM 12K and im having issues recording onto the SSD. It seems to record fine but when I stop the recording an explanation mark appears where the record button is. there seems no way to stop this other than turning the camera on and off.

Im presuming that the SSD isnt fast enough but I thought I got a pretty good ssd. its a Seagate FireCuda 120 2tb ssd with 6 Gb/s SATA speed with 560/540 MB/s (sequential read/write).

Is the issue my ssd isnt good enough? if so What do people reccomend?

thanks

See https://www.blackmagicdesign.com/support/faq/59030 for supported drives.

There is so much more to a SSD than the advertised sequential speed, and most of the important stuff is often not even written in any specs and needs to be measured / tested / ... (things like the max latency when the ssd does internal maintenance operation, size of DRAM cache, sustained rates for full drive write, .... )

I think your issue is power. What you have described, "seems to record fine but when I stop the recording an explanation mark appears where the record button is. There seems no way to stop this other than turning the camera on and off."

That's not the same thing as when recording has stopped because a dropped frame was detected. If the camera continues to record until you stop it, all the while showing the gray exclamation point inside the red recording button, but does not allow you to restart recording, that's not memory problem.

One thing you can try in the hope of extended recording with low battery is to toggle the battery icon between its 3 modes, % number, percent of bar and bar red/white. Do this while recording a low battery and watch for the white led to toggle beneath F2. When you see that, that's your queue to toggle battery display modes to see if one of them makes the white led go off.

Bottom line though, you need to put in a fresh battery.

Ok. I’ve had a lot of back and forth with BMD on this.
In the end it came down to the USBc cable they supplied.
After finally getting a tested and working cable, they mentioned they were in the process of finding a new supplier for that small USBc cable.
It still works perfectly to this day, but I did also notice that they glued the cabling that attaches to the URSA body from the recorder. The part that clicks into the back of the camera. Those cables were all glued together in their little enclosure.

After that debacle and some great advice from users on this forum, I pulled the trigger on some Angelbird Cfast cards. They’re by far the best way forward. Purpose built for cameras and have not shown a single hiccup once.

See if BM can supply you with a new USBc cable.
Cut your losses and get some cfast cards.

I know leave my recorder on the back as a counter balance for shoulder shooting. Also have it as a backup recoding method.

Hope this helps chief

Respectfully, the first thing the OP should do is to simply use an SSD from the officially supported list. A different USB-C cable won’t make a bit of difference if the drive being used isn’t supported.

Oh 100% agree with that! If it ain’t on the list. Quit while you’re ahead.
