Got around to formatting my old Mac. It's running like new again (YAY!). The machine was absolutely temperamental before, and could not be accessed normally (black screen of death, and grey screen lockdowns). Post-reinstallation of the OS (after a standard formatting, non zero-out), it's running like the first day I got it. It seems there was some serious corrupt data on it that crashed it hard last time.
After reinstallation, I'm working on using a data recovery tool (reason why I didn't zero-out) to see if I can get anything back. After that, I might reformat once more and make 2 separate partitions so that I have some redundancy and not require having to boot from the install DVD (and to also work with the most recent OS as well, to maximize compatibilities) to work on it or use defragmentation and disk repair programs (and possibly data recovery tools if this doesn't work the first time around). I am oft reminded looking at my old machine why I like PCs more. So much work to patch them up. Unfortunately, I lack any external HDs that can operate as boot drives.
After attempting to recover any data, I'm going to reformat once more, but with a full zero-out (ensure any hidden corrupts are gone) to ensure safety from now on (and 2 OS partitions like mentioned before; one minimal, the other full-on installations). I should have most-all of my old crap returned next weekend when my sister visits so YAY! After years of waiting, I finally have my old machine back. Looking back at it's specs though, and it's model year, checking with MacMall to find any upgrades, I can't make any upgrades. Outside of being 6 years old, it seems the motherboard and the model seems to have severe limits (seeing as it's a G4 PowerPC Mac, it can't go any further than it's current form; CURSE YOU APPLE!!!).
At least on the upside, I just saved my sister a few hundred bucks for a replacement machine. Reusing it and using it to connect online, I'm learning (or re-learning) it's limits, and may question it's use as a server. Since it's wireless signal tends to be very weak from time to time. I have yet to find a workaround for beefing it's signal up.
