- Simply by changing the id tags on my Linux partitions with efdisk
- I seem to have made the entire disk unreadable. The partitions
- were originally set up with pfdisk and I'd set the id number to
- some "unknown" type just to hide them from DOS. Today I was playing
- around with the new efdisk which came on the 0.96c root disk trying
- to figure out what all I'd have to do to have the new extended file
- system. (Never did figure that out: it'd make a good FAQ.) In
- the process I saw that there was a nifty 't' option to change the id
- type, so I figured I set 'em all to the official Linux number.
-
- Big mistake: when I rebooted the machine (after syncing) I got hard
- drive installation errors in the boot process. I'd had the system
- configured with two IDE drives, DOS on the master, 4 Linux partitions
- on the slave, using bootlin on the DOS disk to boot Linux.
-
- After ignoring the hardware boot errors, I managed to boot Linux from
- a floppy. After resetting the hard drive controller a number of times
- Linux succeeded in reading the recalcitrant drive. And I promptly made
- things worse by restoring the old id types, this time with pfdisk.
-
- Now, no matter what I try, I can't read the drive (Maxtor 120 MB IDE,
- by the way). When I boot Linux from a floppy it repeatedly attempts
- and fails to reset the hard drive controller:
-
- HD-controller reset
- HD-controller times out, c=d0
- HD-controller still busy
- HD-controller reset failed: ff
- controller_ready: status = ff
- HD-contoller reset
-
- and this repeats over & over.
-
- Please, please someone tell me I didn't just toast my drive (which I
- only bought a few months ago specifically for Linux). What incantations
- must I perform to make it whole again? It'd be nice not to have lost
- its contents, but just to be able to use it again would make me
- deleriously happy. Did I destroy the MBR? If so, how can I restore it
- without even being able to control the drive with the HD controller.
- In the meantime I'm stuck with DOS on the other drive :-(
-
- Thanks.
