Usb flash drive not recognised

i’ve been using eos on my starlite laptop (very limited laptop which was made by starlabs) for a few months and experiencing persistent problems with usb flash drives. Eg, a flash drive i was backing up to all day every day (it was auto mounted when plugged) is now no longer detected. If i plug it in and do lsblk immediately i see:

if i do lsbk a moment later it does not appear at all. I recently created a swap file and edited fstab but i don’t think this the cause of the problem (i ran systemctl daemon-reload and have since rebooted). Some sites suggest using fdisk -l to see the drive, but it doesn’t show when i do this.
Any idea what’s happening, ie why a perfectly good flash drive would suddenly become unusable? it’s a big problem because i am not backing up anymore, i relied on the flash drive to back up my files and i relied on another to backup my system using timeshift, that flash drive also stopped working but i assumed it was the fault of timeshift
thanks

edit: i read i should run dmesg -w and then insert usb, this is what i see:

edit2: a person here suggests the following for error -62 which is shown above: “replug it it, then re run lsusb, there will be a few seconds delay! once lsusb picks the device up, just run fsck on it”
is fsck dangerous? could it wipe the usb? if my usb is corrupted i have no idea how that could have happened
edit3: when i run sudo fsck -r /dev/sdb it says “no such device or address while trying to open /dev/sdb …possible non existent or swap device”
edit4: Error -62 does not seem good: "I suspect that the hardware (USB device) is faulty in terms of connection and the kernel simply times out in its attempt to run the device = Error 62. … In the end it was a hardware failure. I turned off the PC, completely shut off the power supply, and let it rest 10 minutes. After that, it never turned on anymore. "

Mm relying on a flashdrive as backup is not a good idea!
To me it seems that your flashdrive is broken, it happens!
Usually after a lot of writing but spontaneous happens too.

You can check you flashdrive with this
sudo fsck -yv /dev/sda1 (check first where the drive is mounted!)

thanks. What is a better way to backup? I don’t want to use the cloud. Is there a safe, reliable solution?
ps, i don’t think i can use the command you suggest, the flashdrive is not mounted, and fsck can’t see it

mm can gparted (or parted) detect the drive?

or in terminal lsusb (with the drive plugged in)

if neither can find your drive you are out of luck…

I use harddisks as backup, it is the most safe method i know.
But i only use those disks to backup, i remove them from my system when i’m done.

ok, that makes a lot of sense. When i saw the price of a hard drive i decided to get a flash drive, i didn’t realise the constant use could destroy it :slight_smile:
