If you were able to format the drive with disk utility then it seems
like your hard drive is actually ok. You can also check the drive
hardware pre-failure status from the terminal by doing
diskutil info disk0 | grep SMART
which should report
SMART Status: Verified
That means, as far as the drive knows, everything is working fine.
You can also install SmartReporter which will notify you if this changes:

Thanks for the very helpful information. I wanted to try a few things before
buying a $99 program to fix the disk. I restored my drive from my Superdooper
backup and it doesn't work better when I boot up from the internal hard drive.
I used disk utility to erase the drive before the restore. Does this mean that
there is something physically wrong with the drive, or does disk utility not
totally erase the drive?
Perhaps this means a visit to the Apple Store.
Thanks for your help in advance.

Hi Jonathan and Rob,
Alsoft's Disk Warrior can be run from a bootable cloned backup. It's just that
running it from the DVD is not accessible because the system can't load
VoiceOver from the DVD. However, if you've installed a version on your hard
drive (either from the DVD or, more commonly, from the download) and have made
a bootable clone with Carbon Copy Cloner or SuperDuper! onto another drive, you
should be able to run this application without problems. Since you won't be
able to run these diagnoses on your MacBook hard drive, you attach a cloned
hard drive, hold down the option key when your press the power on, and then
after giving your system 20 or 30 seconds to start the boot, press either left
or right arrow and then return. You want to have a version of Disk Warrior on
your bootable clone, too, and then run the program from there.
Apple Genius bars used to keep Disk Warrior on a separate boot drive to run on
suspect systems. I think that most diagnostic programs like Drive Genius and
Disk Warrior that are run from the DVD won't be accessible, but if they're
installed on your hard drive and are available on a bootable clone, they can be
run with VoiceOver. (Actually, I'm not sure how much of Drive Genius is
accessible, but I was told that at least some of this program was. I know that
Disk Warrior has been usable with VoiceOver, but I haven't had to do this in a
few years.)
HTH. Cheers,
Esther

This can sometimes occur with a bad disk partition that is being read from. If
this is the case, disk utility will probably not catch it,but disk warrior
(which I don't believe is accessible) will. Installing the OS onto an erased
hard disk partition did wonders for my system performance. But if you can grab
one of the more advanced disk utilities like the above mentioned Warrior and
have somebody sighted with you, you might be able to resolve without
re-installin
Best wishes,

Hello. When I boot from My Mac Book HD, it takes almost 10 minutes to get to
the log in screen and the log in is very slow after entering my password. I
have a Superdooper backup which I used to restart the system, and everything
works as it should. I repaired the disc and permissions on the Macbook HD and
it still takes the same time to restart. I haven't found anything strange in
the login items either.
I also have several time machine backups.
I haven't restored from a time machine backup yet, because I am afraid that I
will still have the same problems afterwards. I have newer files on the
MacBook HD that I want to back up before restoring from the Superdooper backup
which appears to work well and do not want to corrupt the backup.
There is probably something I am missing, but want to check before taking all
the time to try various options.
Any ideas?
Thanks in advance for your help.
