What are the advantages and disadvantages of erasing the internal hard drive with Tiger
versus
Installing Snow Leopard on top of Tiger ?
The whole laptop has been copied to a WD 2TB external drive.
I'm tempted to use them separately because I can't afford to replace
some of the old software.
MacBook Pro, Mac OS X (10.6.3)
Erasing the disk, all the files you don't need will be deleted, so your computer could be faster. However, I recommend to upgrade first instead of erasing the disk. If you see after upgrading that the Mac is slow, make a clean install.
A lot of people do a clean install instead of an upgrade, but I have seen people that have upgraded since Tiger to Mountain Lion without any problem. Also, upgrading you will save time that you will spend if you make a clean install
