Today I made more tests. I dont know but I already noticed problems when 
creating the file system and setting up and copying and writing files on 
the disk SCSI. I would like and test using all type partition on this 
disk. I made 2xBGM, LNX and FAT 32 partitions. I noticed the creating 
file system using mke2fs from command line This process took a very long 
time while writing inode tables. The same when I try to copies a file 
net.tar (lenght about 13MB) for example to ext2 or BGM partition, it 
took a few minutes using cp from command line and directrly in Thing 
when Kobold is disabled. When copying stops after approx. 5 MB for about 
two minutes and then resumes copying and so on, that is, for 13 MB file 
it happens 3 times.
I wonder if it depends on the settings in the file MINT.CNF where I 
FS_CACHE_SIZE = 4096 ?

In addition, when copying a directory with hundreds of small files 
message appeared on the screen

pid 43 (cp) block_io (T) bio_writeout: RWABS fail (ignored, -10))

The next question is it depends on the driver disk drive?
I use the newest version 10.01 and test new version 10.03 (toppic is on 
the hddriver forum)

Do you mean options Background transfer (MagicAtari) in HDDRUTIL in this 
moment is disabled
