Thinkware F750 Card Error

Dee_82 · Dec 6, 2016

you obviously know you stuff but you have overlooked one thing, the problem isn't directly linked to the SDcard, or corrupt memory etc, I believe that its because the SD card is used as some sort of scratch disk, its used to store information on the video / camera which the camera for whatever reason needs to read back, reading back the incorrect or incomplete information from the card might be enough to cause the camera to have a fit

aptones, your cards are running in to a wall, you should be getting way higher read speeds on a class 10 card

You may be absolutely right but this is related to firmware implementation, may also be related to timing issues not just read and write speeds, note the new generation of dash cams boast the they no longer need periodic formatting meaning that were there is a will there is a way.
It may be hardware related, timing out issues, there are some extremely bright guys and girls out there with time on their hands to investigate, let's hope that someone gets to the bottom of this.
Specs and protocols for configuring and communicating to sd cards are all on the net, someone needs time, a logic analyser and a scope to check what's going on and hone in on the sequence of events triggering the restart or memory corruption.
Wish I had the time, easier to keep an eye out for a more reliable device in the long run and cut our lisses

indeed, what will happen knowing thinkware is that they will release a new dash cam called the thinkware f790, inside it'll be the exact same hardware as the f750, maybe with a new outer shell, but will contain a new and improved firmware, all for a small 250 quid.

if it's doable thinkware won't do it, they will make you buy a new device which will be identical to the last one

I did wonder about the read speeds as it's rated at 45mb....
Although I was using the Thinkware usb adapter... wonder if that's the issue.

Got my 128mb card today.... the F750 didn't like it at all.... might try formatting it to see if it works. I'll be really p1ssed if they locked the card size with the new firmware update!

EDIT: Turns out you can't use the Thinkware DashcamViewer to format a card if it's a blank SD card - which is a stupid thing! I ended up copying over the folder structure plus a few videos and after that it was picked up by the Dashcam Viewer. Formatted and now ready for me to use a bit later....

Seems the USB MicroSD reader from Thinkware was on the blink..... bought a new USB3.0 reader and re-tested the MicroSD cards.

This is the 128MB Toshiba M302 Exceria

My USB card reader which came with the F750 died within weeks, they really must be low quality devices.

Mine died last week... ended up buying a USB 3 card reader!

On a different note.... for the life of me I can't get my 128GB MicroSD card to work.... just keeps saying "Insert memory card"...... formatted it exFAT and FAT32 and still no joy!
Need to find another 128GB card to see if it's the same issue (in which case I hope the new firmware doesn't lock out large cards).

After all the messing around, I've finally bitten the bullet and forked out for a 64GB Thinkware branded card.... due to arrive today, so hopefully some test results to come!

Great thread , thanks guys
.
But still......................... which card I'll pick in 128 + GB

aptones · Jan 13, 2017

I ended up getting the Thinkware 64Gb card which is good enough for me to record my journies to and from work..... Not had a single problem since installing it over a month ago (no reboots or errors)..... so far... *touch wood*

I think someone mentioned the Lexar 633x 128GB as being a card that works....

You may find that 32GB is not enough..... each 1min of video is 80meg.... so 160meg if you have a dual camera setup..... which means any driving over 3.5hrs means it just over writes the older videos.
(Then again if you're only using it to catch accidents then it's fine.... unless you're like me and want to check out that hawt chick that walked by earlier.... wait, did I say that too loud?)

Haha

love the last part you said , I know even 32 is not enough but it was coming free so I grab it going to run for a while and will go 168+ GB, want little more feed back as thikware said max size is 64GB
Rite now my dash Cam is only running for the beauty purpose

and everything is safe

Gama7362 · Jan 28, 2017

today after running for around 2 weeks F750 refuse to sleep with Samsung EVO+ 32GB

Any tips ?

CatchMyNeighbor · Jul 24, 2017

Any word on the Lexar 633x card 64GB? This is the card BLACKBOXMYCAR.com suggests using and i can't get it to work. I've formatted using the Dashcam viewer. Tried it blank on the cam itself. Tried copying the files exactly from my Thinkware 16Gb to this one. No luck just keeps power cycling and saying "memory card error, restarting"

The latest batch of 633x seems to have this issue. If the Thinkware dash cam rejects the card no amount of formatting will make it compatible unfortunately.

CatchMyNeighbor · Jul 25, 2017

Thanks BlackBoxMyCar. Does anyone have a list of 64GB cards that work well for the F750? Meaning it works and has been tested park and drive mode for continuous months of use, as of July 2017'? Other than the Thinkware brand, obviously. Also not sure if it matters but I am part of the unfortunate F750 owners who have regrettably upgraded to v24 firmware and didn't get to upgrade mine to a F770.
