Well, yesterday was about the worst experience. So, I bought a 512 GB Sandisk SD Card…yadda yadda…was going to use the good old linux utility “dd” (disk define/disk delete/whatever it stands for) to clone the old SD card contents from the phone.
It was intended to give ample storage for large audio files.
Letting my lowest-end Samsung phone format it was a YUGE mistake…somehow it borked the whole disk…
And for some reason I didn’t have exFAT as a filesystem on my main Linux box, and booting into Windows 10 didn’t do a damn thing.
Eh…I don’t know what I did, but the disk ended up unrecoverable, even using some KaliLinux tools to just vaporize the thing…
Meh. Finally got exFAT up and running on my regular Ubuntu 20.04.6…and had to deal with my attempts to store the contents of the old 32GB SD card, which apparently, in storing it as a file, gobbled up many GBs of storage in my root partition on the box…which involved, really just nuking a bunch of .cache files…
No. Never ever trust a phone to format a card. Because when it stalls because of screen timeouts or whatever, it’s a major PITA.
But on the good news, exFAT works fine with the Samsung, so at least it’s an adequate filesystem for any reasonably modern purpose.
And another thing, WTH did I use as the filesystem on this 250GB flash drive? Huh…didn’t like storing +4GB size files…weird…I couldn’t have been that stupid…but…one never knows.
And, yes, with dd, I did learn a good trick: add “conv=notrunc,noerror” for fun. I don’t think “notrunc” is that useful, but “noerror” is a good one.
Since an older spinning HDD is starting to “click,” that will be handy when trying to grab some stuff off it (pretty sure there’s no content there I don’t have duplicated elsewhere, but I don’t have a RAID setup, and just manually use sync/rsync from time to time…I think this drive was used as an experimental multi-boot drive for various linux distros and VMs and some ancient backups).
/* edit, what’s odd is that my kernel is 5.15.0-76-generic and there was still no exFAT under /proc/filesystems … TBH, I don’t know what I’ve done to my current basic daily “driver” box, but something bad, no doubt. Let’s just say I’m very familiar with (initramfs). */
