The partitions should still exist if the disk partitions weren't deleted and formatted, so an easy way would be do this from a console and copy and paste the output here:

 

su (enter root password when prompted)
fdisk -l

 

that is an lowercase L. This will list all the partitions on your disk, and so if /dev/sda1 exists, it should be here, and listed. If not, then I would say that when Mandriva was installed, the disk was erased and used just for Mandriva.

Fdisk clearly shows that sda1 and sda5 are being picked up by the system. Please also post the output of:

 

$ cat /proc/partitions

 

If sda1 and sda5 are not listed in the above(likely), you can manually create the device files for them in /dev using the mknod command. To test for sda1 run as root:

 

# mknod /dev/sda1 b 8 1

 

If mknod runs without error and creates /dev/sda1, try mounting it and see if it works.

Thank you....

I'll try now

 

 

[goga@localhost ~]$ cat /proc/partitions

major minor #blocks name

 

8 0 312570167 sda

8 6 102759741 sda6

[root@localhost goga]# mknod /dev/sda1 b 8 1

[root@localhost goga]# mount -t ntfs-3g /dev/sda1 /media/win_c

Error opening '/dev/sda1': No such device or address

Failed to mount '/dev/sda1': No such device or address

Either the device is missing or it's powered down, or you have

SoftRAID hardware and must use an activated, different device under

/dev/mapper/, (e.g. /dev/mapper/nvidia_eahaabcc1) to mount NTFS.

Please see the 'dmraid' documentation for help.

 

mknod have create /dev/sda1

Try mounting with just ntfs instead of ntfs-3g:

 

# mount -t ntfs /dev/sda1 <mount point>

 

Also, check if sda1 shows up with cat /proc/partitions after running mknod.

Finally, is sda1 shown in Mandriva Control Center > Disks? If so, is any further information given about sda1? Is this a standard ntfs windows partition, i.e. not a Windows Dynamic Disk?

mknod finish without errors but sda1 not exist in /proc/partitions

 

about windows standart partition... i think partition is standart.

i have installed opensuse 10.2 - 11.1, ubuntu 8 and never have such problems.

they saw my disk normally

 

about mcc>disks: this program exit abnormally

I'm beginning to wonder about the health of that hard drive; that's pretty odd behavior. If you have adequate external storage, I recommend backing up your data now. Also, go to the the hard drive manufacturer's website and download their hard drive diagnostic utilities iso; all the major hard drive manufacturers have them for free. Run the diagnostic utility in thorough mode and see if any problems are detected.

 

Other things I would try - boot with any linux livecd and see if you have any problems picking up sda1; boot up mandriva and immediately after booting up run:

 

$ dmesg | grep sda*

 

That will print out all the kernel messages relating to sda. See if any I/O or read/access errors are reported. Those types of messages can mean a hard drive that is starting to fail.

The other thing I thought of, since the MCC was crashing is whether the integrity of the packages installed are OK, or whether they are slightly damaged because of a bad ISO burn, or a bad MD5 sum. But, as pmpatrick says, check that disk first, but also boot some LIVECD and see if it works any better at accessing your disk. Ubuntu LiveCD is generally pretty good without major problems.
