Reinitializing your computer’s internal hard disk

You initialize your internal hard disk using a program called Internal HD Format, which is on the floppy disk labeled Disk Tools that came with your computer. If your computer came with a CD-ROM drive and you didn’t receive floppy disks, you can find Internal HD Format on the CD-ROM disc that contains system software.

1Start up your computer from the Disk Tools disk or the CD-ROM disc that contains system software.

See “Starting Up From a CD-ROM Disc” or “Starting Up From a Floppy Disk” earlier in this section.

2Double-click the Internal HD Format icon to open it.

You may need to look in a folder called Utilities to find Internal HD Format.

3Type a name for your hard disk in the Name box.

4If you want to make sure that none of the hard disk’s original information is recognizable after reinitialization, choose Zero Data from the Options menu.

If you choose Zero Data, initialization may take a few minutes. (If you don’t choose Zero Data, initialization will take less than 30 seconds.)

Click Initialize.

A message informs you that initializing the disk erases all information on it.

Click OK.

During initialization, a status bar shows you the progress of the initialization.

When initialization is complete, click Done.

If a message reports that initialization failed, try again. If initialization fails a second time, take the disk to your Apple-authorized service provider for repair.

5200 LC, 75 LC specifications

The Apple 75 LC and 5200 LC are notable members of Apple's lineup that emerged during the 1990s, catering to different market segments while showcasing the company's commitment to innovation and design. Both models brought unique features and performance enhancements, pushing the envelope of personal computing at the time.

The Apple 75 LC, released in 1993, was designed as a lightweight, compact Macintosh that filled the gap between the more expensive Mac models and entry-level options. This computer featured a 68030 processor running at 25 MHz, which provided ample power for both educational and professional environments. With 4 MB of RAM, expandable to 36 MB, and a 320 MB hard drive, the system delivered a reliable performance for everyday tasks. The 75 LC was equipped with a 12-inch grayscale display that showcased excellent clarity, perfect for word processing, graphic design, and software development.

One of the distinguishing features of the 75 LC was its simplified architecture, which allowed users to expand functionality through various peripheral devices. This model supported Apple’s innovative ADB (Apple Desktop Bus) for connecting multiple devices simultaneously, including keyboards, mice, and other peripherals. Furthermore, the 75 LC came with built-in Ethernet, making it easier to connect to networks and share resources, a vital feature for businesses and educational institutions.

In contrast, the Apple 5200 LC, launched in 1995, was aimed more at home users and small businesses. It utilized the more advanced PowerPC 603 processor, offering improved performance at 75 MHz. With support for up to 64 MB of RAM and larger storage options, users experienced a noticeable boost in multitasking and application performance. The 5200 LC maintained compatibility with Macintosh software, ensuring a smooth transition for users upgrading from older models.

The 5200 LC also featured a 14-inch color display, which ushered in a new era of visual computing for personal users. The graphics capabilities were enhanced, enabling better performance in multimedia applications and games. Moreover, the device was designed with an emphasis on ease of use, incorporating a handle for mobility and a sleek form factor that allowed it to fit seamlessly into various environments.

In conclusion, the Apple 75 LC and 5200 LC represent two significant advancements in Apple's computing technology during the 1990s. While the 75 LC provided a solid entry point for users in need of a basic yet functional system, the 5200 LC catered to those looking for enhanced performance and multimedia capabilities. Both models showcased Apple's dedication to creating user-friendly, powerful, and expandable computing solutions, solidifying the company's position at the forefront of the technology landscape during that era.
