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.

6200CD Series, 6300CD Series specifications

The Apple 6300CD and 6200CD Series were notable additions to Apple's line of portable computers in the mid-1990s, blending compact design with functional capabilities that appealed to both personal and professional users. These series were part of Apple's PowerBook lineup, embodying the transition to more powerful and versatile portable computing.

The Apple 6300CD was recognized for its striking design that combined portability with performance. It featured a high-resolution grayscale display, offering a clear and vibrant viewing experience, which was essential for graphic design and multimedia tasks. One of the standout features was its integrated CD-ROM drive, allowing users to easily access software, music, and multimedia content, thus enhancing productivity and entertainment options.

The core of the 6300CD was the PowerPC 603 processor, clocked at 100 MHz, which provided a significant performance boost over its predecessors. Coupled with a generous amount of RAM, it handled multitasking and demanding applications with relative ease. The 6300CD also offered several connectivity options, including Ethernet, SCSI, and ADB, which made it adaptable to various networking and peripheral configurations.

On the other hand, the Apple 6200CD Series brought a balance of performance and affordability. This model also featured a PowerPC 603 processor but at a slightly lower clock speed, making it a cost-effective choice for users who did not require the highest specifications. The 6200CD was designed with a more basic but still effective color display, targeting users who needed reliable performance for everyday tasks, such as word processing, browsing, and basic graphic work.

Both series were equipped with a robust suite of software, including the classic Mac OS, enabling users to utilize a wide array of applications. The inclusion of a trackball, along with a full keyboard, contributed to user-friendly navigation and productivity, making these laptops appealing for a broad audience.

In summary, the Apple 6300CD and 6200CD Series exemplified the innovation and design ethos of Apple during the era. With their combination of solid performance, portability, and user-friendly features, these PowerBooks were well-received in the 1990s and remain a nostalgic reminder of Apple's commitment to creating powerful, efficient, and aesthetically pleasing computing solutions.
