The QEMU project is currently considering to move its bug tracking to another
system. For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state
back to "New" within the next 60 days, otherwise this report will be marked as
"Expired". Or mark it as "Fix Released" if the problem has been solved with a
newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
Bad sectors when using MS-DOS 6.22
Status in QEMU:
Incomplete
Bug description:
When I try to install DOS 6.22 in QEMU, I get many disk errors when
the virtual disk is beeing partionized and formatted. When I later do
a SCANDISK, I can see many bad sectors and file errors.
I have tested this with the following disk formats: qcow2, vmdk, raw.
I tested this on Windows 7 with the following command line and QEMU version:
qemu-system-i386 -name "Windows 3.11 WfW" -machine isapc -cpu 486 -boot
order=adc -m 32 -soundhw sb16 -hda disk1.qcow2 -vga cirrus
qemu-system-i386 --version
QEMU emulator version 2.8.50 (v2.8.0-12557-g0bd1f6b1b2-dirty)

I then did a test with the linux version of qemu, which gave me the same
results.
Command line: qemu-system-i386 -name "Windows 3.11 WfW" -machine isapc -cpu
486 -boot order=adc -m 32 -soundhw sb16 -hda disk1.qcow2 -vga cirrus -monitor
stdout
Version: qemu-system-i386 --version
QEMU emulator version 2.1.2 (Debian 1:2.1+dfsg-12+deb8u6), Copyright (c)

I also checked the disk image with qemu-img, with no results:
No errors were found on the image.
7986/8000 = 99.83% allocated, 0.20% fragmented, 0.00% compressed clusters
Image end offset: 523698176
Because I got the error with two different versions of QEMU, I think
this is a general problem and not related to a specific distribution.
I have attached a zip file with screenshots of SCANDISK, which shows
the disk errors.
