Realising I left away this point of your previous msg :
Someone, maybe not Eric, asked what I have been using for accessing
USB mass storage in DOS. Answer : a version of Panasonic's
USBASPI.SYS. This allows access to 4k sectors using SCSI commands.
I had a look at Bret's open source USB drivers, unfortunately they
only support Intel/Via (UHCI) controllers yet.
True. Working on that.
I also think they have hard coded 512 bytes per sector.
No. USBDRIVE reads the maximum buffer size from the DOS List of Lists (as
discussed some earlier
The advantage of a write-delay cache is that that the writing can be
done when the system is idle (a simple form of multi-tasking).
That counts as advanced cache with a lot of code and can go as far as a
sort of ramdisk which syncs
back to the harddisk slowly but steadily when the

is this too simplistic or what (?):
you could reformat ntfs and use a freeware reader,
or reformat the whole hard drive and then use that...
or i've had excellent luck with USBASPI.SYS 2.27 +
DI1000DD.SYS (links below).

That's promising, even to see if your drivers can really make FDISK
work. I probably should prepare a bootdisk

Trust me, it works. I've partitioned many USB disks from DOS, though I
normally use Ranish Partition Manager instead of FDISK (it's MUCH easier to
use, and will also format the partitions).
I know MS FDISK will crash
I use NTFS under Windows. Mark Russinovitch offered a freeware NTFS

old Sysinternals site, and a payware driver that could also *write* to
NTFS from DOS through the sister
Winternals site. (It was intended for rescue operations on NTFS
filesystems from DOS.)

Hi Bret,

I am saying that for gaining speed on modern disks, in particular
flash disk ands large sector disks, you should already make a big
difference with a small pooling cache and a short delay,
That's true -- but I don't think either LBACACHE or UIDE actually do that. I
could be wrong, but I
Hi Eric,
So... If anybody has NWCACHE (ask me if needed) they could try if
NWCACHE with 555 msec delay and 16 kb lookahead / write-combining
buffer and delayed/deferred/combined/pooled/whatever writes on is
already making a quite nice difference in write speed, eg. on USB

Hi,
It's been a while since I've used DR-DOS, mostly due to the floppy
drive on that machine not working. I never moved it to any other
machine as I didn't see the point (though vaguely considered it). It's
kinda old and has some hardcoded limits.
I don't remember exactly how much total RAM
Hi Alain, Bernd, Eric:
I followed the instructions below from Alain, using my Fedora 14 (Linux)
box. I didn't have 100% success but I am much closer! I created an image
file in the manner described below. I wondered where to find command.com
and kernel.sys...so I downloaded the FreeDOS iso
