I've noticed with some programs if I create an IMG larger then 2.88 I get "sector not found reading drive a" when the program tries to load.  Usually this is with a program that'd normally take 3+ diskettes that I've joined into one large IMG file.

Having this issue currently with the newest version of NTFSPRO for DOS.  The program makes 3 diskettes that I joined into one IMG file.  It boots fine to the dos prompt, then when I try to execute the NTFSPRO.EXE I get the sector not found error.  Didn't have this issue with the older version of NTFSPRO which also took 3 disks.

Is this just a program error on their part?  Or is there a way I can create the IMG to help prevent that error message?

Thanks for your help.

NTFSPRO.EXE may not support abnormal diskette emulation. You can try BCDW or CDSHELL to load it.

When I tried booting that image with cdshell, I get a Disk I/O error.

Any other ideas?

Do you try a 5.76MB image? which may work.

Tried your suggestion size, same error.

I don't get it however, it's not even attempting to load the boot files which are ME os files.

I'll try that same image size with just the boot files w/o the program files just to see if it boots that.

Meantime, any other ideas?

Another suggestion is switch to different DOS: DOS 6.22, DOS 98 and FreeDOS, as well as try WinImage 7.0 to create a large floppy image.

I use WinImage 7 for all the images, that's what I used to do the custom size earlier.

I tried just the OS files with ME and kept the image at 5.76, still Disk I/O error.  I'll try another OS, could this be a size limitation of memdisk?

No. memdisk can emulate up to 500MB image. It is NTFSPRO.EXE which does not work under emulating environment.

So far I haven't been able to get any boot img file to work over 2.88 with memdisk.  Does anyone have a sample boot img over 2.88, hopefully 5.76meg, that I could download to try?

Got it to work.

In WinImage I told it to "Export to an image with a mbr".  Used that image file on the cd and works great now.
