I/O error
Cause
Some physical Input/Output error has occurred. If the process was writing a file at
the time, data corruption is possible.
Action
First find out which device is experiencing the I/O error. If the device is a tape drive,
make sure a tape is inserted into the drive. When this error occurs with a tape in the
drive, it is likely that the tape contains an unrecoverable bad spot.
If the device is a floppy drive, an unformatted or defective diskette could be at fault.
Format the diskette, or obtain a replacement.
If the device is a hard disk drive, you might need to run fsck(1M) and possibly
even reformat the disk.
Technical Notes
In some cases this error might occur on a call following the one to which it actually
applies.
The symbolic name for this error is EIO, errno=5.
Is a directory
Cause
An attempt was made to read or write a directory as if it were a file.
Action
Look at a listing of all the files in the current directory and try again, specifying a file
instead of a directory.
Technical Notes
The symbolic name for this error is EISDIR, errno=21.
