We have device files defined in linux based on the controllers what we are using.
For ex:-
1. For IDE controllers device file name is - hda/hdb/hdc.....[depends on the number of ports supported]
2. For SCSI controllers device file name is - sda/sdb/sdc...[depends on the number of ports supported]
hda1 would be first partition on drive hda
hda2 would be 2nd partition on hda
etc.
Same with sda
So you say you have 2 seperate drives?
Does that mean hda1 is my current C drive and sda1 is my D drive? I have only 2 drives currently.
That sounds correct.
Windows has a tendency to scatter it's system files across the drive. Defragmentation will give you more space and reduce possibility of losing files if you plan to have Linux share the same drive. It is not uncommon to require defragging 2 to 3x depending on how long Windows was in use. You can then shrink the partition making space for Linux.
3 GB minimum, 10 GB or more recommended if you plan to install additional software from the repository.
