OT: backup warning
Date: 03.03.10 16:03 (Wed, 03 Mar 2010 16:03:09 +0100)
From: Markus Winter
Hi all,

probably not necessary here but a little backup warning:

I do weekly backups with Time Machine (as I hide the hard disc in case I get
burgled it is too much hassle to get it out every hour ;-)

Last week my hard disk started to make faint clicking noises while idle -
quite annoying too. So I immediately made a backup and left the backup hard
disk connected.

My replacement hard disk came on Tuesday morning, so I put it in and
restored from the Time Machine backup. According to the backup the last one
was done on Tuesday at 1:13 pm.

However after restoring and restarting I can find no file younger than last
Friday - even on the backup drive. Time Machine did not give a warning - in
the menu it always said "Last backup <time given>"

So in short if you hear a faint click click from your hard disk it might be
too late to trust Time Machine.

Best Regards

Markus

P.S. I'll put the defect hard disk in an enclosure and will start up from
there - might be able to recover some more recent files that way

For data rescue, see http://www.prosofteng.com/. Not associated in other
way than as a relieved customer after a disc crash.

HTH,

If your old drive hasn't actually died yet, you should just do a
direct clone from it. Generally, there's no damage until you have
several severe crashes (i.e., computer freezes and must be powered
down).

I had run TechTool Pro over it - after just checking 20% I had 79 bad blocks
and stopped it there before I made things worse. The drive was showing
read/write errors on some files (so a clone is out) but I hope I might be
able to get some of the newer ones still off intact

I didn't recommend it, and I don't recommend it as an only disk utility tool. The original poster stated that he used it and stopped it after it spit out a large number of error messages. From experience with the product, and from things that I have read, I do know that it can report bogus errors if you do not have the proper version.

Not sure what your are trying to sell here Harrie,

> Be absolutely sure that you have the latest and greatest version of

because,

• You are not a huge fan of TechTool Pro, except as a tool of last
resort
• It reports all kinds of problems that were totally bogus
• Files it says were zapped worked fine
• You tend to go with DuskUtility and DiskWarrior as primary disk
utility apps

> I still keep updating the crazy app though as a just in case kind

Just in case it might actually do what it is supposed to do?

Why would you be recommending TechTool Pro then?

Be absolutely sure that you have the latest and greatest version of TechTool pro for whatever version of the operating system you are running. I am not a huge fan of TechTool pro, except as a tool of last resort. I have had times in the past when it reported all kinds of problems that were totally bogus and no other disk testing app would report. Then to top it off files it said were zapped worked fine. I still keep updating the crazy app though as a just in case kind of thing. I tend to go with Apples Disk Utility and Disk Warrior as primary disk utility apps. Fortunately, quick where is there some wood to knock on, I have never had a boot disk crap out on me. I have had secondary drives go bad though. I always have at least two internal disks with SuperDuper! making a second boot drive on a daily basis and Time Machine doing its thing on an external drive in addition.

I would, as someone else mentioned, attach that disk as an external, non-startup disk, immediately stop Spotlight from indexing it, and try dragging over lost files to new folders on your new drive.
