My Ubuntu OS does not recognise any external drives or devices. This started after I installed Windows XP. When I run GParted, it shows "unallocated 465.76 GiB". I ran "sudo fdisk -l -u /dev/sda" and this is what I got-
Device Boot Start End Blocks Id System
/dev/sda1 4001790 108857343 52427777 5 Extended
Partition 1 does not start on physical sector boundary.
/dev/sda2 45946880 108857343 31455232 83 Linux
/dev/sda3 * 108872505 171766979 31447237+ 7 HPFS/NTFS/exFAT
Partition 3 does not start on physical sector boundary.
/dev/sda4 171771904 976773119 402500608 7 HPFS/NTFS/exFAT
/dev/sda5 4001792 45944831 20971520 83 Linux
I can't figure out what's wrong with my partition table. Please help.
