Repairing a damaged disk

If you see a message reporting that a disk is damaged or unreadable, you may need to repair the disk.

Try these suggestions first

If you can’t start up from a hard disk or you don’t see the hard disk icon on the desktop, try the following:

mIf the hard disk is internal, shut down your Macintosh, wait at least 10 seconds, and then turn it on again.

mIf the hard disk is external, make sure that it is turned on and that its cable is connected firmly; then restart the Macintosh.

mIf the hard disk is your startup disk, start up with a different startup disk. (See the following section, “Starting Up From a CD-ROM Disc.”)

If, after you start up from a different disk, your hard disk’s icon appears on your desktop, reinstall system software on the hard disk. (See “Installing or Reinstalling System Software” later in this chapter).

mCheck the ID numbers of all SCSI equipment connected to your computer. Each device must have a unique ID number. The computer itself has the ID number 7 and the internal CD-ROM drive has the ID number 3. The ID numbers 0, 1, 2, 4, 5, and 6 are available for additional SCSI devices.

Also check that the chain of devices is terminated properly. For information on setting SCSI ID numbers and terminating a SCSI chain, see the manuals that came with your SCSI equipment.

mIf none of these suggestions solves the problem, test the disk by following the instructions given later in this section.

5200CD, 5300CD specifications

The Apple 5300CD, released in 1995, represents a unique chapter in Apple's history, catering specifically to the needs of mobile professionals and educational institutions. This portable Macintosh laptop was notable for its blend of performance, portability, and multimedia features, making it a versatile choice for various users.

At its core, the Apple 5300CD was powered by the PowerPC 603 processor, which operated at a speed of 100 MHz. This architecture was a significant shift for Apple, marking its transition to a more powerful and efficient computing platform. The device typically came with 16 MB of RAM, which was expandable up to 64 MB, allowing users to run applications smoothly, even for the demanding software of the time.

One of the standout features of the 5300CD was its display. It featured a 12.1-inch active-matrix LCD monitor, providing vibrant colors and a resolution of 800x600 pixels. This made it suitable for a range of tasks, from word processing to graphic design. The inclusion of a built-in CD-ROM drive was also a highlight, enabling users to access multimedia content and software directly from CDs, a relatively new and powerful feature at that time.

In terms of connectivity, the Apple 5300CD offered a range of ports, including a serial port, a SCSI port for connecting peripherals, and an ADB port for Apple devices. This ensured compatibility with various accessories, such as printers and external storage solutions. The built-in modem facilitated internet access, allowing users to stay connected in an increasingly digital world.

The laptop's design was another noteworthy aspect. It had a compact and lightweight form factor, making it easy to carry, which was essential for users on the go. The significant battery life of around 3 to 5 hours provided the mobility needed for professionals who relied on their devices throughout the day.

While the Apple 5300CD is often remembered for its distinctive design and robust features, it also faced criticism due to its reliability issues, particularly with its logic board. Nonetheless, the model represented an important step in Apple's evolution, paving the way for future portable computing devices.

In conclusion, the Apple 5300CD was a trailblazer in portable computing during the mid-1990s, featuring a powerful processor, a vibrant display, multimedia capabilities, and a compact design. Its introduction underscored Appleā€™s commitment to innovation and adaptability in the rapidly evolving technology landscape of the time.
