nserialhd() vs serialnumber

[Marc Vanzegbroeck]

Hello,

What is the different between the serialnumber returned by nSerialHD() and the number returned by the dos-command

wmic diskdrive get serialnumber

I'm always use nSerialHD(), but I see that the other number is also with characters, instead only numbers.

Unfortunately give this also a number.

? NUMTOHEX( NSERIALHD() )

Can I see a sample of such serial?

nSerialHD() = 410452486
NUMTOHEX( NSERIALHD() ) = 18770206
wmic diskdrive get serialnumber = S3TRNA0M316529

nSerialHD() returns the number of the VOL command.

Yes now I see.

It's NUMTOHEX( NSERIALHD() ) that give the same result as the VOL command.

So NSERIALHD() is not the real serial-number. After re-formating it, it will be different then.

There are also utilities to change it
