If you have the startup disks, use the main install disk and start up holding down the C key after the chime. When startup finishes, check out the menus, follow the instructions to format the drive (do partitions if you wish), then re-install the system. Study the steps because I may not be recalling all that is there. With a G4, I would not go beyond 10.5, but other opinions may vary. My G4 (733 & about 1.5 GB memory) is slow with Tiger. You could try just a clean install which will not wipe out the drive, but without more information I don't know what you need.

Hello, someone donated an old G4's to me. It has an administrator password set up that won't let me get around it but, I don't mind deleting the entire HD and starting over since I do have a G4 startup disk. Soooooooo how do I (or can I) delete the HD and reinstall the startup disk and start over? Everything about it seems fine and I can get into it under the "no password" log-in option. It's running 10.4.11

Thanks,
David

I second the use of Truecrypt. It is an awesome free open source project.
The FBI could not crack it in the case of a banker in Brazil suspected of
fraud:

For work all my external drives need to be encrypted. I have a macbook at home but PC at work. I can't find an external hard drive that can be encrypted and work for both. I'm sure they exist. I use kingston flash drive without any problems but I need something much bigger.

Thanks Jim

I think the battery is going soft.

From System Profiler I have the following.

Full Charge Capacity 3279mAh

Charge 3237mAh

Cycle Count 241

Battery Voltage right after full charge indication 12050mV

So it looks like the voltage is not getting to 12.6 Volts. I will keep an eye on it.

The charged usage time has gone down but I sort of expect that with age. It is around 2-3 hours. Looking at the System Profiler the battery has gone through 241 cycles.

Key battery information can be extracted using utilities such as Battery Health Monitor (free app) or by going to the Apple icon in the upper left corner of the screen and clicking on About This Mac>More Information>Power. Lithium ion batteries used in the MacBook's early models usually are good for at least 400 charge cycles, although I've got one with over 600 cycles that's still going strong. The other figures you should pay attention to are the fully charged voltage, which should be 12.6 volts or better, and the amount of original battery capacity remaining, which is expressed in mAh or milliamphours.

Lithium ion batteries like those in your MacBook slowly lose their capacity, even if they aren't being used and just sit on the shelf in their original packaging. Thus the reason I look at eBay sales of "new" batteries with a jaundiced -- and experienced -- eye. But you never know. I've got a $30 eBay third-party battery in my 2.16 GHz MacBook that shows a current capacity of 5004 mAh, which Battery Health Monitor says is 104 percent of the original capacity of 4800 mAh.

So your battery seems to be aging normally. The Service Battery icon may indicate a charging anomaly, such as loose connection, or perhaps an internal battery issue. If the battery gets hot to the touch when charging or discharging, I'd keep a close eye on it as that may be a precursor to a battery overheating or even catching on fire situation. Or it may be nothing more than the little "brain" inside the battery being confused. This can occur if you don't practice the Apple-recommended drill of unplugging your MacBook and letting the battery run down once a month or so. Besides being good for a good long battery life, it lets the battery's brain reset itself. I've often seen batteries regain substantial amounts of charge capacity after a monthly full-discharge cycle. YMMV.

HTH,
