"CNTL-ALT-DEL" required. Fixed mine after updating to 2019.20.4.2. Turn car off in security/safety screen, pull USB drive, wait five minutes, Press scroll wheels in while stepping on brake. Insert USB drive after it boots back up. No reformatting required.
Just tried it and still only have sentry.

Wow, strange. This procedure worked for me the first time. I came from v. 2019.15.103 (what the car was delivered with on 6/26. On 6/27 it updated to 2019.20.4.2 and many problems surfaced, including this one.
You can use a partition larger than 32gb, but Windows will insist to format any driver larger to ntfs which won't work with TeslaCam.
If your computer is Windows, you'll want to use an app to format it.
Since most flash drives tend to fail when used for a dashcam, you'll want to use a drive intended for dashcams or a SSD.

Do yourself a favor in the long run and order a larger USB device. If you park in a lot of parking lots where people are walking by all the time and Sentry files get saved, get at least a 128GB or 256GB. That 32GB will fill up in no time.
Kind of wonder if your drive has lots of bad cells and simply can't record the buffer any longer or there's no room for any sort of saved files. May not have any relation to the new software installed since I haven't seen others really having this (no TeslaCam Icon) complaint after updating. When a drive becomes unusable it will let you view files already recorded but won't let you write any more or let you reformat.
BTW when you say Sentry is working does that include recording new alert files? Have you watched anything newly recorded? or does it mean that only the red eye on the screen pops up to warn people?

Actually have 3 128s that stopped working with 2019
20.4.2. I know this is release related as I have been using them since I bought the car. None will work above 32 on the TeslaCam. Sentry works just fine just not for normal driving.
I’m using a card reader with a 256GB micro SD card (actually have two to switch off between them when I pull one to check files) and am on 2019.20.4.2 for a little while now. No problems here on this version with the dashcam or Sentry mode. Just checked the card the other day and working fine. I do use a Mac to format my microSD cards for FAT32 and reformat using Apple’s Disk Utilities. Using a Samsung Endurance card and a Blackvue card. Both made for dashcam use. I use the full 256GB for recording on TeslaCam.
Are your USB drives/SDcards getting hot to the touch? If so that’s sometimes an indication the card is bad.

Yes, formatted fat32. It works with sentry but not teslacam. So has to be fat32.
Are you using windows software to do this. Heard that you need to use a third party software if on windows to format.
There is a difference between FAT32 and exFAT. I discovered my windows software formats as exFAT or NTFS and there is no option to format as FAT32 using the default windows formatting option on my windows laptop. Formatting as exFAT gives me sentry icon only and no recordings. Formatting as FAT32 resolves the issue (for me anyway).

You get the Sentry icon whether or not you have a usb plugged in. Sentry Mode does 2 things, 1) constant recording from cameras while parked and 2) triggers the speaker alarm with music when it detects force on the car. Without the USB, #2 is active (though Tesla says sentry video does get sent to the cloud, but there's been no way for us to access it if so).
