Downloaded a USB device driver for DOS called DUSE. After loading it and restarting into the DOS system, the external hard drive was found, but unfortunately, the sectors couldn't be read correctly because the driver only recognizes sector sizes of 512, 1024, 2048, while my external hard drive has a sector size of 8192.郁闷郁闷...

It would be best to ask here.

I also encountered such a problem. In DOS, the drive letter can be found, but it cannot be read. How to solve it?

Then what is the specific situation of your USB device? What kind of USB device is it?

usb1.1 external hard drive

Some parameters may be needed to load normally. The specific parameters can be seen in the "DOS Articles" section:

In addition, you may wish to try the newly added USB driver "Motto Hairu", which can also drive USB hard drives:

I want to buy a USB flash drive. Can it be driven under DOS? Which driver to use? Is there a USB driver? Can I run the programs in it?

At present, the USB flash drive cannot be driven under DOS, unless it is a DOS booted from the USB flash drive.

Is a USB flash drive a USB disk?

My USB drive can also find the drive letter, but it can't read the content. It's a USB drive for a laptop, not the kind for a desktop, ultra-thin. I don't know how to set it to make it work. I've spent a whole day without getting it sorted out.

USB flash drives are thumb-sized FLASH electronic disks, such as Longshine U-drives, Patriot Mini-disks, etc.
rrdn, or you can study its parameters. I don't have a USB drive here and can't test. Each cluster on the CD seems to be 2048 bytes.

Additionally, you can also try USB_CD and Motto Hairu to drive USB optical drives.

How to use Motto Hairu to drive a USB hard drive

There are three drivers in Motto Hairu, namely the USB ASPI manager, floppy disk, and hard disk drivers. For specific details, please refer to the instruction file inside.

----------
"motto hairu" DOS Driver

----------

This driver enables "motto hairu" USB interface on DOS.
IEEE1394 interface can not be used on DOS.

There are three drivers as DOS Driver.

USBASPI.SYS : USB1.1 mode ASPI Manager
RAMFD.SYS : RAM DISK driver for USB floppy, if you have only single USB port and access both.
Di1000dd.SYS : ASPI HDD driver

1. If you does not have USB floppy

Copy USBASPI.SYS and Di1000dd.SYS files and
add following 2 lines to config.sys on the boot disk.

device=USBASPI.SYS
device=Di1000dd.SYS

After that, connect "motto hairu" to USB port, then set this disk to FDD, and
power-on PC.

2. If you use USB floppy

Copy USBASPI.SYS, Di1000dd.SYS and RAMFD.SYS files and
add following 3 lines to config.sys on the boot disk.

device=RAMFD.SYS
device=USBASPI.SYS /W --- Use /R option, if you have multiple USB ports
device=Di1000dd.SYS

And confirm
device=himem.sys
is exist in config.sys.
If you don't have, add following 4 lines.

device=himem.sys
device=RAMFD.SYS
device=USBASPI.SYS /W
device=Di1000dd.SYS

When power-on, during booting, contents of FD is copied to RAM disk, then,
when the copy is completed, following message will appear.

===============================================
=== Connect the target device to USB port. ===
=== Press



key.
Boot will continue from RAM disk.

NOTE:
1) After changing DOS mode with rebooting Windows, it can not work.
You must power off once.

2) Option settings

USBASPI.SYS has following options.

/R : Access also USB FDD.
: RAMFD.SYS may be needed in some cases.

/W : Prompt following message for swapping floppy and device, if you need to boot from USB floppy and have only one USB port.

===============================================
=== Connect the target device to USB port. ===
=== Press
