First let me say I already know there is another topic about a similar problem, that problem is different from mine and the listed solutions did not fix my problem.

MS-DOS 6.0 includes many new utilities and features, including a disk defragmenter, disk compression, anti-virus, a new backup system, and pc-pc file transfer tools. It was heavily criticized as buggy by the media, primarily due to file corruption issues with DoubleSpace and the lack of tools to repair such issues. MS-DOS 6.22 Supplemental Utilities. My copy of MS-DOS includes a fourth disk titled 'MS-DOS 6.2 Supplemental Utilities,' which can also be obtained from the link above (grab the version for MS-DOS 6.22, named SUP622.EXE). This disk is not mandatory, and mostly just includes some extra features from previous versions of DOS that were dropped for. I saw the links you mentioned above. In the second link, it has many dos versions ranging from 3.3 to 6.22. And on GitHub, Microsoft/MS-DOS provides 1.25 and 2.0. I want to use MS-DOS for studying and working, which version should I choose? My pc uses intel e3 1230 v2 cpu, and has a asus p8b75-v motherboard. It has 12 GB memory.

I'm using VirtualBox 2.0.2 under Windows XP. When I get to this part of the setup:

I can't get past it. It refuses to recognize disk 2. Anyone have a workaround? I tried unmounting and then remounting the disk image but it doesn't work.
Also these same disk images work fine for installing MS-DOS in Virtual PC 2007.
Occasionally when I 'dir |more' on the disk, MS-DOS hangs. Occasionally more.com will stop working from the disk and won't do anything until reboot.

scandisk.exe (installed from disk 1) has no problems with the disk (although I get the 'multiple arrow key press' bug in that app).
Disk 2 has 60 files with 1358277 bytes. I can post a more detailed file listing if someone else has something different.
Any ideas for a workaround?
[Edit: Huh VPC refuses to mount them now for some reason... wtf. I swear they were working before. Maybe they worked in VPC2004 (I have 2007 now). Weird. I'm gonna try and install MS-DOS in another VM and convert the disk into a VDI.]
[Edit: Fixed it! I used a different set of floppy images. I suspect something modified my first set (VirtualBox seems to be able to... tsk tsk. Doubt it was VirtualBox though.)]
