USB Stick Oddity

Assuming Windows 10:
1. Start an elevated command prompt (right-click CMD.EXE and select "Run as Administrator"). 2. Run DISKPART 3. Type LIST DISK to list the available disks 4. Type SELECT DISK N where N is the number of the disk you want to interrogate. 5. Type LIST PART to list the partitions 6. Type EXIT when done

Gparted from a Linux boot USB / DVD is a handy tool for such things.
Have you got / tried these tools OOI?

Might be worth a go (or to keep in your portable media toolbox). ;-)

dd would fix that.
The sequence would be to boot lunux from a live dvd, and use dd to copy the entire usb disk including partition info, and then use dd to pop it back onto a new one
Or if you have enmough USB ports do a stick to stick clone
dd if=/dev/sdb of=/dev/sdc BS@96 or whatever the actual usb sticks end up as

If you don't mind losing the contents, you can just reformat with the appropriate partition alignment settings. Both Windows (DISKPART) and Linux (parted) allow the alignment to be specified at partition creation time.

Ah. never had the need to do that. I like te idea of dd becausse it is pretty much the option that ensures thet the byte patterns are identical. If that doesnt work its 99% sure to be a hardware issue and no point in wasting more time on software fixes.

Yes, creating an exact byte-for-byte copy is an advantage of dd.
It's got some inherent limitations due to its method of operation, like being unable to expand or shrink filesystems (which can be more of a problem than you think, because even drives that are nominaly the same size are normally not *exactly* the same size). But it's an impressive tool given that it's about 45 years old.

OK I've dug out an old XP system - reformatted the USB stick re-copied and no change the MP3 boogey box still doesn't see it.
SO, I've also dug out a copy of Linux MINT on CD and tried the 'dd' clone that was suggested, but I'm getting 'access denied' on the source USB stick which I don't understand. So I've used the gui 'format USB Stick' under mint on of of the new sticks which ran ok so then copied MP3 files onto it but it still isn't seen by the boom box :( :(
argh . . . . !

Reformatting the memory stick will just re-create the filesystem on the existing partition. If the partition alignment is the problem (a big if), this won't fix the problem.
What you'd need to do is to delete the existing partition and then recreate it with the "correct" (for your media player) alignment and then format that to create the filesystem.
I realise I'd been a bit sloppy in calling re-partitioning "reformatting" in my earlier post - sorry for that.

You probably need:
sudo dd ...
Because you need to be root to access the raw device.

My recently purchased Cruzer blade sticks had a built-in security arrangement, which meant when I copied something onto them from one computer and tried to see it in another, there was nothing there.
The solution was to put the stick back into the original computer and delete the security files and folders and the file I'd originally copied. I recopied the file I wanted to copy to the second computer back onto the stick, and everything worked fine on both computers after that.

I have a similar problem with Sandisk ultra sticks. The older one I have works ok as a OTG stick for my mobiles, but newer ones don't. I was using them for TWRP backups. But I stumbled across something that works all the times in all my mobiles and that is a micro sd card in a usb adaptor.

I had to get a ramstick multi way copiers firmware updated last year to cope with the more modern hardware. On a pc you can simply get different drivers, but on old fixed gear there is little you can do unless there is updated firmware made for it. Their web site might have it. Brian
