cp file to mSATA (universal disk format) resulting in I/O error depending on file name characters(?)

English Hardware

Hi,

I cannot do rsync or cp on my external mSATA. It results in an input/output error. I’m testing two files where the error appears but it seems related to the file name characters not to the file itself which is strange. I did

cp --preserve --verbose --force  '/home/andreas/Dokumente/Musik/Aufnahmen/Auf in den Osten – Let’s Go East!.rtf' '/run/media/andreas/UDF-Externe-Festplatte/Musik/Aufnahmen'
cp: cannot create regular file `...': Input/output error


cp --preserve --verbose --force  '/home/andreas/Dokumente/Musik/Aufnahmen/Auf in den Osten – Let’s Go East!.txt' '/run/media/andreas/UDF-Externe-Festplatte/Musik/Aufnahmen'

no error

The strange issue is, when I manually interchange and rename both file extensions (.rtf renamed to .txt and .txt renamed to .rtf) on the source device then the identical errors happens: .txt gets copied but .rtf not, although .txt is actually the original rich text file and .rtf is the original text file.

Any hints or solutions or (debug) ideas to look at? Thank you.

I did format the mSATA by https://github.com/JElchison/format-udf with no errors like this:


./format-udf.sh sdb 'UDF-Externe-Festplatte'

well, guess l have to give the answer myself: I could not solve this issue. My intend was to have a drive that can be read on all computers. I tried:
[ul]
[li]mkudffs --utf8 --blocksize=“512” --udfrev=0x0250 --lvid=“UDF-Externe-Festplatte” --vid=“UDF-Externe-Festplatte” --media-type=hd “/dev/sdb”[/li][LIST]
[li]it got me read only access [/li][/ul]

[li]mkudffs --utf8 --blocksize=“512” --udfrev=0x0201 --lvid=“UDF-Externe-Festplatte” --vid=“UDF-Externe-Festplatte” --media-type=hd “/dev/sdb”[/li][ul]
[li]worked partially but same errors as above, could not get any detailed information on “could not create regular file … input/output error” [/li][li]tried to access file name limits to check issues:[/li][LIST]
[li]getconf NAME_MAX /dev/sdb [/li][li]255 [/li][li]getconf PATH_MAX /dev/sdb [/li][li]4096 [/li][/ul]

[li]have no clue why these input/output errors repeatedly occurred [/li][/LIST]

[/LIST]

Eventually I decided to format the external drive again:
[ul]
[li]gparted /dev/sdb[/li][LIST]
[li]1 small volume ntfs (to have an ext4 Windows reader there) [/li][li]1 large volume ext4 [/li][/ul]

[/LIST]

Now the drive works smoothly on Linux but I have no instant access on other computers.

I wonder if anyone managed to get universal disk format working without problems especially with long file names or non ASCII characters.

NTFS name restriction are different and more restrictive then Linux file systems in general. I suspect you reached some limit on NTFS or the Linux drivers could not handle the name mangle. General rule to keep all OS happy is don’t use space in files name use underscore. On NTFS all names are mangled down to the old 8.3 DOS format so first dozen or so letters should be different to avoid confusion to the mangle routines
