Write the errors that you get.
I don't remember but I think it was
Fail on INT 24
Code:INT 24 - Critical Error Handler
no input data
on entry to INT 24:
AH = bit 7 of register AH is set to one if other than disk error
= bit 7 of register AH is set to zero if disk error
AL = failing drive number
AH = bits 0-2 indicate affected disk area and read/write status
¦5¦4¦3¦2¦1¦0¦ AH
¦ ¦ ¦ ¦ ¦ +---- read = 0, write = 1
¦ ¦ ¦ +------- 00=DOS, 01=FAT, 10=DIR, 11=data area
¦ ¦ +-------- 0=FAIL not allowed, 1=FAIL allowed
¦ +--------- 0=RETRY not allowed, 1=RETRY allowed
+---------- 0=IGNORE not allowed, 1=IGNORE allowed
DI = error code in lower byte
BP:SI = pointer to device header control block where additional
information about the error can be found
Thanks.
