I went years without doing this, with zero issues. The drive was always formatted with ext4. However, when trying k6.1 builds, my USB3 drives got trashed. After that, I had read you should unmount them before shutting down. I added this to my shutdown script, but not sure it entirely works when files are open. Usually this would only affect those using Entware.
Code:
umount /dev/sda1
umount /dev/sdb1

I also did the latest update without deactivating the flash drive (ext4-kernel 6.1) and there were no problems
It is because your partition is sda1. sda is the drive itself. If you had multiple partitions, they would most likely be sda1, sda2, etc. sda is the entire drive, not the partitions. However, you CAN format sda and use the full drive without partitions. Makes things a bit confusing if you are not familiar with doing this. What you have is fine. _________________ Linksys EA8500 (Internet Gateway, AP/VAP) - DD-WRT r53562

Yep, you should be good. I have the same as I have two partitions sda1 (opt) and sda2 (jffs). My sda shows the same as yours, for years. Not an error. _________________ Linksys EA8500 (Internet Gateway, AP/VAP) - DD-WRT r53562

I had read somewhere, that every time you want to update the dd-wrt build, you should deactivate the flashdrive (USB Support > opt,jffs) correct?
Suggestion: change the subject of this thread from "[DD-WRT update information]" to "Flash DD-WRT firmware after turning off USB?" _________________ Router: Asus RT-N18U (rev. A1)
Drink, Blink, Stretch! Live long and prosper! May the Force and farces be with you!
with last command you can go to extreme and unmount with magic number command..
echo u > /proc/sysrq-trigger
you can download your update files at /tmp so those will not be affected by the unmount...
for the record i used to download my files to /opt and than flash with no unmount...than delete the files from /opt ..i know it was a dirty game but it was ok... _________________ Atheros
