Low Level Disk Routines

[Shift838]

I am new to assembly and want to be able to utilize the use of low level disk access routines such as sector formatting or track formatting. Also was wondering if assembly routines can be called from Visual Basic?

Where can I find sample assembly code for low level disk access?

Hi Chris77504,

For low level disk access, you can use interrupt 13h. You have to know what functions you need (i.e. Read, Write, Verify, etc..). Because they are many function you better read it yourself. Grab interrupt list documents here:

Yes, you can call assembly routine from HLL such VB. However if you want to call an asm routine for hardware access and calling it from VB (under windows), you must know the limitation. There are other things that you have to do prior to the call of the low level disk access.

Take a look at this:
