Apple 145B manual Hard disk keeps stopping and starting again

The hard disk keeps stopping and starting again.

mThe hard disk may be going to sleep to conserve power. Open the PowerBook control panel and move the Battery Conservation slider toward Maximum Performance.

The hard disk is full.

mYou can reclaim space on your hard disk by removing unneeded files; turning off virtual memory; or purchasing a disk optimization program to reorganize the information on the hard disk.

The icon of a floppy disk doesn’t appear on the screen.

mThere may be a problem with the disk or disk drive. Try inserting a different disk. If its icon does appear, the original disk is probably damaged. You may be able to repair the disk or recover some of the information on it. See Chapter 8. If the icon of the second disk does not appear either, take the computer or disk drive to an authorized Apple service provider for repair.

A disk you use with your PowerBook computer is not recognized by another Macintosh.

mSome disk drives cannot recognize high-density disks. If the disk is high-density (marked with the icon î), try inserting an 800K or 400K disk in the disk drive of the other Macintosh. If that works, copy your files to an 800K disk or a 400K disk. If you regularly plan to use floppy disk drives of different types, use the lower-capacity disks in all drives.

mThe disk may be damaged. Try using Disk First Aid or another disk repair program to fix it. If this problem occurs frequently, one of the disk drives may need repair.

You can’t eject a disk from a floppy disk drive.

mThere may be a temporary mechanical problem with the disk drive. Restart the computer and hold down one of the trackball buttons while the computer starts up. If that doesn’t work, carefully insert the end of a straightened paper clip into the small hole near the disk drive’s opening, and push gently until the disk is ejected.
