I've just tested on Win98 plain DOS mode and 213600 gives:
blocks = 32768, bsize = 4096, resulting in 134,217,728 or 128MB...

2F1510 gives:
blocks = 308862, bsize = 2048, resulting in 632,180,736 or ~602.9MB

Under Windows (DOS box) with 217303, I get:
blocks = 19275, bsize = 32768, resulting in 631,603,200 or ~602.3MB

Properties for my E: drive gives 631,603,200, that's what 217303 is
reporting.

Best regards,
Norberto

PS: I've tested with a CD-ROM, because I've not a DVD-ROM at hand at this
moment...
