I wondered if my rear cam (Transcend DP100 with Transcend 32GB class 10 card <the black one>) captured something of interest earlier today.
When I got home I pulled the card, only to find that the last recording was two days and several hours driving previous. The cam had apparently stopped mid-journey with a corrupted file.
I tested the cam and its card using a wall charger and it just sat there with a solid red LED but wouldn't record (flashing LED). Unfortunately I hadn't noticed the lack of flashing red LED in my rear-view mirror due to bright sunshine and making a long journey on roads I had rarely used.
I tried a different card (formatted in the cam) and it worked fine.
I estimate the card had completed around 100 overwrite cycles when it failed.
H2testw on the suspected card showed this:
The media is likely to be defective.
0 KByte OK (0 sectors)
29.7 GByte DATA LOST (62308352 sectors)
Details:0 KByte overwritten (0 sectors)
0 KByte slightly changed (< 8 bit/sector, 0 sectors)
29.7 GByte corrupted (62308352 sectors)
0 KByte aliased memory (0 sectors)
First error at offset: 0x0000000000000000
