Is this a typo? The MBR should be at lba sector 0
Yes it is a type. Of course =0 is correct. Good eyes you have... :-)
dosemu used to refuse to touch a partition that was mounted, but I It was not mounted, because dosemu was running - see the difference? :-) The new dosemu has some bullshit features. See that on the msdos list
You don't have to touch the hardware to have the ribbon cable or connectors stop working. ribbon cables and connectors are cheaply made and not terribly reliable.
It is _not_ the cable. A cable cannot break withing a minute... well you know what I mean. read the other mail i wrote there that i can dd-read data from hda. but how many bytes have i got to skip and read the rest to restore my data to an image which i can later mount and copy files from?
You haven't tried anything to write the MBR without reading it first. maybe it isn't so bad. maybe
dd if=/dev/zero of=/dev/hda bs=512 count=1
that clears the mbr with zeros, and then?
would succeed. Of course, it would destroy the partition table, but what good is a partition table you can't read? I doubt it will work.
fully true what you say.
If it is an old 486 with a VLB bus, there are IDE interface chips that will scramble the HD such that you can neither read nor write it, - if you don't tell the IDE driver there is one. It can detect and evade the PCI version.
no its p2-266 pci
If that is the case, the only way to make the drive usable again is to use the hardware format track command. AFAIK there is no ioctl for does that apply for mine? i think not.
that, except one I wrote a long time ago for the 2.0.x and 2.2.x kernels and put aside. If I hook up the HD they are on, it might still work. Some BIOS's claim to be able to do format, or there is the msdose install.
thanks lawson for trying to help. summarized I can say that accessing the hda is possible only with "dd" command (bios reads chs data). my idea is to clear mbr and then skip some 512-xxx bytes then then (where does hda1 start?) dd the whole bunch to an image. but what about geometry of harddisks in general 1. mbr 512 bytes 2. partition table 1 (how many bytes???) 3. partition table 2 (backup of 2.) and then the actual hda1 data. this is where i should start copy from. know what i want? -- *º¤., ¸¸,.¤º*¨¨¨*¤ =Oliver@home= *º¤., ¸¸,.¤º*¨¨*¤ I http://www.bmw-roadster.de/Friends/Olli/olli.html I I http://www.bmw-roadster.de/Friends/friends.html I I http://groups.yahoo.com/group/VGAP-93 I I http://home.t-online.de/home/spacecraft.portal I
