I'm a bit reluctant to suggest windoze solutions but then again ..... As a first instance get hold of the 'partinfo' utility from powerquest - i.e. ftp://ftp.powerquest.com/pub/utilities/partinfo.exe

Boot from a win9x floppy to command line (dos) and run partinfo - it will tell you how partition-magic views your partition table. You can then use a partition editor to fix the errors (if you're brave enough!). Looks like you can use the PQmagic one from : ftp://ftp.powerquest.com/pub/utilities/ptedit.exe .

Partition Magic itself (latest versions) offers to fix some partition table errors itself. Please note, however, that there is no universal agreement on exactly what you can and can't do in a partition table. Some OS-provided partitioning utilites do things with the table that other OSs don't like or recognise.

e to fix,backup & restore the partition table,without any
relationship with OS type,only an operation to the HARD DRI

Hi,

There are a variety of utilities out there. Another good one is V-com's partition commander --> http://www.v-com.com/product/pcp_ind.html .

If you don't fancy paying money there is a copy of pqmagic 6.01 at a well-known warez site out there but I don't think experts-exchange (or powerquest !) would like me to tell you exactly where. Why not look at the ranish partition manager -->  http://www.users.intercom.com/~ranish/part . Thats freeware of some sort I believe.

Regards

in fact the unix cd has one of the best partition solutions..
also don;t go beyond the 4 partition limit. a hdd can have at the most 4 partition ( no logical drives included) otherwise it may cause problems with some BIOS or dos and windows.

as far as the linux utility goes, start the setup from the Cd  and chose fdisk...if you use it properly yule lov it...
only thing is that you cannot move a partition,, but for anythign else you can really do it.

ok,kiranghag :
   i know what you mean,but this time,when i use a RH cd to
"fdisk" my HD,it can NOT let do so because of the partition
table damaged,so your solution is unavailable for me,anyway

t to pay for such stuff :) i will accept your solution,hop
e to see you next time
