i always just
cat /dev/??? > /dev/nullto make sure the usb blinks
–status=progress. So happy when they added this.
/dev/disk/by-id/xxx works for me. Never made a mistake.
Always
lsblkbeforedd. The order of /sdX might change from boot to boot. Only /nvme doesn’t change.Why is this?
This is the only reason why I still use GUI for making Linux USBs. Can’t trust my ADHD ass to write the correct drive name. Also, none of my USB drives have a light.
Popsicle is pretty nice, it doesn’t let you choose the internal drives afaik.
I am become dd, the destroyer of disks
Don’t confuse if and of!
IMHO, it was a mistake to make USB block storage use the same line of names also used for local hard disks. Sure, the block device drivers for USB mass storage internally hook into the SCSI subsystem to provide block level access, and that’s why the drives are called sd[something], but why should I as an end user have to care about that? A USB drive is very much not the same thing for me as a SCSI harddisk. A NVMe drive on the other hand, kinda sorta is, at least from a practical purpose point of view, yet NVMe drives get a completely different naming scheme.
That aside, suggest you use lsblk before dd.
At least sata is well on its way towards dying, so the problem will solve itself in some more years.
My machines all have nvme exclusively now, only some servers are left using sata. And I would say the type of user at risk of fucking up a dd command (which 95% of the time should be a cp command) doesn’t deal with servers. Those are also not machines you plug thumb drives into commonly.In 5-10 years we will think of sda as the usb drive, and it’ll be a fun-fact that sda used to be the boot drive.
While we’re at it, can we also rename the hard drive block devices back to
hdinstead ofsdagain? SATA might use the SCSI subsystem, but SATA ain’t SCSI.Yeah lsblk, lsscsi, fdsik -l , go have a coffee, come back later and hit enter on dd
I still made the mistake, when I sleep deprived switched if and of somehow
My then girlfriend wasn’t exactly happy, that all here photos and music, which we just moved off old CDs, that couldn’t be read correctly anymore, and I spent quite some time to finally move themObviously the old CDs and the backup image were thrown out/deleted just a few days earlier, because I proudly had saved the bulk of it - and being poor students having loads of storage for multiple backups wasn’t in reach.
Backing them up again to fresh CDs was on the plan, but I quickly needed a live USB stick to restore my work laptop…Since then I’m always anxious, when working with dd. Still years later I triple check and already think through my backup restoration plan
Which is a good thing in itself, but my heart rate spikes can’t be healthy
“/dev/sdb? It’s sdb? With a B? Yep that’s the flash drive. Just type it in…
of=/dev/sdwhat was the letter again? B? Alright,/dev/sdb. Double check withlsblk, yep that’s the small disk. Are my backups working properly? Alright here goes nothing… <enter>”Sounds like someone’s not up to date with their backups.
heh i do it hardcore, my USB has no light ;)
You all still have a LED inside USB flashdrive?
I buy them specifically with LED. It s helpful for data transfer, but also helpful for doing a flash of new OS to old nas hardware… You have to hold reset button in on nas until you see it start to read USB (by LED) then you know you can release the reset button.
Yep! I just installed Void about ten minutes ago off a 2GB stick from the mid-2000s. Somehow, those little sticks just keep going!
Same! I have a 4gb white SanDisk stick, from like 12-14 years ago and is still working 💀💀 it even died on me once, and started working again after a few days 😳😳
Keep them around. I was playing with and testing some ~15 years old mobos for work, and they would not boot from any USB3.0 stick I tried. Same images on an 8GB USB2.0 stick booted with no problem.
Name and shame: Biostar motherboard
for an usb, it might work. For such an old hard drive, it won’t. Linux will refuse to boot
I don’t think so. Block device is a block device.
Maybe you have better knowledge, please elaborate.
?
Remember kids, always lsblk before you dd
ls /dev > /tmp/before
<insert usb>
ls /dev > /tmp/after
<repeat two more times>
diff /tmp/before /tmp/after
<sweating>You could just open gnome disks
ok grandma, go back to facebook /s
Yeah once I forgot I had an external drive on one of the USB ports on my PC and created an Ubuntu drive with dd and just sent it do /dev/sdb …lost all movies I had on it. After that I always check with df -h or fdisk -l
