Soooooo
i have this V3 drive from Sharksym and it works nicely
i do have a problem with inserting the 8 GB flashcard in a cardreader in a linux system
although i can read the files and partitions that are on the flashcard ok ,the V3 drive can not
i am guessing linux (i tried in Debian and in Mint linux) it doing something with it?
i also tried in two card readers with the same problem

does anyone happen to know whats happening ?
any tips on how to solve this?

i have to copy everything on the msx now since i can not use it in my linux computer and it takes a bit too long

thanks

not completely clear on the steps you perform - so, is this 8Gb flashcard functioning ok with the Sharksym drive before you insert it into flashreader in linux?

yes
i do the initialising with the V3 drive itself
so i have one fat12 partition
next i make the other partitioner with the software thats is described in the manual
and everything works
but
as soon as i put the card in my cardreader it wont function anymore when i put it back in the V3 drive....

ok, that's weird of course. btw, what do you do before you pull it from you cardreader? some ejecting provided with GUI by desktop environment or some commands from console? i'm not sure if i know how that modern UI ejects works because i'm going oldschool way with console commands. but if you use console it is not enough to just unmount partition, you also need to eject the drive, like (assuming your drive is /dev/sdb and you used first partition):
sudo umount /dev/sdb1 && sudo eject /dev/sdb
btw, i'm curious what happens with those flashdrives, is that linux damages the partition table or so... hmmm...

That's bad, you should make sure the filesystem is synced. You could simply run the 'sync' command, or use eject with your desktop environment thing, that will also make sure it's synced.

oh, please avoid this. since linux use caching on disk operations more than windows - when it says files are copied - it actually means that files are in filesystems cache, not on the CF card yet Smile use the eject feature. even simple `sync` command should work too, as Manuel suggested (but still, proper eject is preferable)

seems i have the problem solved
it looks like its the way the partitions are made that did the trick
now i have one 32 MB partitions (made with the V3 drive)
and 3 logical partitions in a extended partition and this seems to work (so far)
the manual has it arranged in another way (which clearly did not work for me)

the caching thing cant have been the problem every time since i tried and tried and remade the partitions at least 10 times and paid attention to not to take it out too quickly

and even if the would have been the problem... why only on the V3 drive sd card and never on any of the other interfaces i have?

anyways

problem solved

did you own the Sunrise IDE/CF one maybe? It seems that the partitioning of those two are pretty much similar. And yes, if you make more that 4 primary partitions it will not be compatible with type MSDOS partition record btw. You should go for 4 primary at most, or three or less primary and one extended, where you can make arbitrary number of additional partitions
