MG, there is another critical piece of information needed, if I
understand what you've been saying correctly. Could you post the
contents of your /etc/fstab file, please? That provides the information
that gets mounted at boot time. It is possible that the contents of
/etc/mtab might also be of interest. But if you can get the partitions
to mount manually the cure may be as simple as adding or repairing
entries in /etc/fstab.


Also only /dev/sda is valid in your fdisk retuns for the first drive.
/dev/sda1..N are partitions on /dev/sda. But in this case you provided
more information than requested rather than less. When you're unsure
that's not a bad idea.

Summarizing it (for easier follow-up) shows this:

Disk /dev/sda: 164.6 GB, 164696555520 bytes
255 heads, 63 sectors/track, 20023 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x7e91a39a

   Device Boot      Start         End      Blocks   Id  System

/dev/sda5           19648       20023     3020188+  82  Linux swap / Solaris

Disk /dev/sdb: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xb51fa8fc

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       19457   156288321    7  HPFS/NTFS

Disk /dev/sdc: 400.0 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x524a757d

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1       48641   390706232    b  W95 FAT32

Disk /dev/sdd: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x227f1d55

   Device Boot      Start         End      Blocks   Id  System
/dev/sdd1               1         392     3148708+   7  HPFS/NTFS

That sums to about 1TiB.
