Hmm Interesting, thanks for your response Phil. It looks like the G90 is very 'picky' at accepting TF cards.
Finally got my G90 and did a few tests. Generally everything (including day & night footages, suction cup, cables, etc.) works fine except for one issue: I kept getting 'Invalid' file in the playback mode.
The Issue:
The first approx 30mins of footage files are fine. Up to a certain point, all subsequent footages/photos are rendered invalid.
When I check these files on my computer, they cannot be played despite the files hold the full weight (usually 356mb per 3min footage).
This, I suspect, is due to the memory card. I bought a
Samsung EVO 64GB Class 10. I conducted a few tests to determine if the culprit is the TF card.
The Tests:
1. I first ran the G90 on my TF card with its original out-of-the-box format (
NTFS), for about 40 mins non-stop. When checked back in playback mode, the first 30-35 mins worth of files had no issue. Then came 'Invalid' file for the remaining minutes.
2. After the first test, I re-formated my TF card to
FAT32 using the
FAT32 Formatter as recommended by
@jokiin. Ran the 2nd test recording for another 40 minutes. Same thing happened again.
3. Disappointed, I then decided to just throw my
Kingston 4GB class 4 in, ran another 30mins + recording, ironically, got no invalid file this time. I'm still running this test at the time of writing this post and it's been fine so far.
During the Tests, I press the 'Reset' button mutiple times but that diddn't help.
My Conclusions:
There are two possible reasons:
1. my G90 doesn't like 64Gb
2. My G90 doesn't like Samsung EVO brand TF card
Other considerations:
These are the considerations I thought may possibly link to the memory card issue, please take it with a grain of salt.
1. Limit of the number of files on the TF card: Due to the low storage space in my 3rd test, the files are overwritten more often so I'm not sure if the G90 had enough room to create enough files/footage for the 'Invalid File' to appear. Hope I make sense here. For example, assuming that it takes 18 working files on the 64Gb Samsung to generate the 'Invalid Files' subsequently, the 4Gb definitely isn't capable of storing 18 working files since they exceed 4GB, hence it won't store any invalid files. Not until I get a hold of the
64Gb Kingston card, I won't be able to deduce this possibility.
2. Firmware: G90-ZX-A730-1437-N7H. I suspect a firmware updated is needed?
Future Initiatives:
I've decided to purchase another
Kingston 64Gb Class10 and will be determined to run the same tests again. I probably should have listened to your advice
@jokiin..
Not sure if I missed out anything on the memory card configuration, or if this has occurred to anyone b4 me, I simply reported my situation for the sake of contribution. If anyone can help, I very much appreciate it
To be continued...
Cheers.
