- Can anyone help me to get some information of an old half-corrupt 20MB
- miniscribe hard disk? (611 cylinders, 4 sides, 17 sectors of 512 bytes each
- per side).
-
- I have been using Norton Utilities Advanced Edition to read Absolute
- sectors giving the absolute side (0-3), cylinder(0-610) and sector (1-17)
- address and pulling files off sector by sector. I have the FAT and most
- of the directory structure.
-
- Using NU is very laborious, what I need is information on how to use a get
- DOS call to readsuch absolute sectors myself. I am a reasonably competent
- programmer (I know how partitions, boot sectors, FATs, directory structures
- work). I will be doing the work in Turbo Pascal version 3, a program to read a
- 512 byte sector given absolute side, cylinder, and sector would be very nice. I
- know how to do a DOS call from Turbo Pascal as the manual documents how
- to read the timer. WHat I don't know is what is the DOS call to read an
- absolute sector and what parameters does it take.
-
- Please answer by email. Thanks in advance for any help.
