- I am in trouble. The machine which supplies my wife with
- access to alt.callahans, rec.sewing, etc seems to have trashed
- it's disk. I am at a loss, and in severe danger of great
- suffering.
-
- Here is the story - all help is appreciated.
-
- The machine is a 286 running microport. It has 2MB ram and a
- 42MB ST506 disk which is a type 17.
-
- One fine day, I boot it, and after it checks memory and comes
- up with the hardware config information, it says unto me:
- Error loading system from fixed disk.
- It normally says
- noise[system5]:
- then after a suitable delay starts the boot.
- Obviously, it cant read the boot block from the primary
- partition. It seems that this is a part of Microport.
-
- Now, I have cnews and a whole bunch of stuff on this machine.
- Naturally, no-one in his right mind would want to back up 38
- MB onto floppies, so I dont have a recent backup. I would
- dearly like to get my bytes back. Recompiling the news
- software on a 286 is a sad business. Plus the missus wants
- her goodies back too ("You arsehole, why didnt you take
- backups?" "Duh - Ummm.")
-
- Some test were run:
- All BIOS read and seek tests pass.
- I can boot unix from the floppy.
- fdisk describes the Unix and Dos partitions correctly.
- I can boot dos (first 100 cyls of disk).
-
- So the drive and the partition table are both ok.
-
- Having booted DOS, I try the following:
- mount /dev/dsk/0s0 onto /mnt
-
- It says 'Drive 0 Type 15'
- Error reading super block.
- It is getting a disk error trying to read head 5 sector 1.
-
- This is a no-no because the drive has only 5 heads numbered
- 0-4. And it is a type 17, not a type 15 as stated. I can
- understand that it thinks that the super block is creamed. I
- dont know why it wants a type 15 drive, when the cmos setup,
- and fdisk, all agree that it is a type 17. Is it on drugs?
-
- So I muck about some more, and I get to a stage where
- mount /dev/dsk/0s0
- returns
- Not a file system.
-
- And
- divvy -d
- returns
- Invalid partition end record.
-
- (This may be because the selected partition was somehow changed
- to be the dos partition - I didnt think of this at the time, and
- now I am here, not there, and cant check. )
-
- So the question of the day is:
- Why does the boot floppy decide my disk is a type 17
- when all the indications are that everything else
- thinks it is a type 15?
- Any hints?
-
- (For that matter, is there anyone out there?)
