<div class="moz-cite-prefix">Hi Michel,<br>
<br>
Thanks for you answer. I'm using an Ikea KOPPLA (<span class="pip-product-identifier" data-ga-action="article_number_click" data-ga-label="details_204.150.27"><span class="pip-product-identifier__value">204.150.27</span></span>)
which provides 17W. It's powering two v3 probes and one v4 probe.
The other probes work well, so i don't think that the power supply
is causing this.<br>
<br>
What i meant was, that maybe some USB sticks are to slow and thus
not able to perform writing of a big chunk of data in the expected
time, and therefore the USB flash/filesystem is considered broken?
Can you tell the exact cause for the "Flash drive filesystem
corrupted"-tag is? What triggers this?<br>
<br>
I am aware that USB 3.0 is backwards compatible, but since USB 3.0
sticks are faster, maybe it makes sense to stick with them (hehe),
to ensure that at least the full USB 2.0 potential is used.<br>
<br>

<pre class="moz-quote-pre" wrap="">Hi Simon,
First thing that comes to mind to me, do you maybe have a power problem? If the unit receives just enough power to boot the base TP-Link, but not to power the USB stick this may trigger these problems. Would you be able to boot the unit with a different power supply (try 5W at the least or 10W), to see if this makes a difference?
Speed shouldn’t be much of an issue, USB to my knowledge is backwards compatible.
Cheers,
Michel

Hello,
i have two v3 probes and i'm experiencing issues: "USB Flash Drive Filesystem Corrupted"
I have tried multiple USB Sticks, including brand new ones and also sticks from "good" brands like Lexar and Sandisk.
The issue is not permanent, the error appears and disappears from time to time:
2022-12-22 @ 12:14:04 UTC Probe auto-tagged Your probe #xxxxx was automatically tagged as "system: Flash drive filesystem corrupted"
2022-12-22 @ 18:14:42 UTC Probe auto-untagged Your probe #xxxxx was automatically untagged as "system: Flash drive filesystem corrupted"
This leads me to the thought, that the flash storage is not the real problem. It's unlikely, since i tried multiple dongles. Could it be possible, that not the flash storage is broken, but the speed of the USB dongles is too low?
All dongles I tried were USB 2.0, not 3.0, since the TP-Link TL-MR3020 is not USB 3.0 capable anyway. But maybe USB 3.0 is a better choice?
What do you think?
BR,
Simon
