View 6 Replies View RelatedOS X :: Crashed Hard Drive Secure?
Sep 10, 2009I swapped out my stock 160GB HDD for a 500GB WD HDD a year ago and put the old HDD into an enclosure. I guess I didn't screw it in tight enough and after jostling around a move or two, I just plugged it in to clear the clicking sound of a crashed drive. I can't even mount it onto my computer, so I pretty sure it's gone. My question is: I was about to take it to Best Buy to put in their electronic recycling bin, when I wondered if whatever data that was on there is secure, and if there's another step I should be taking before disposing of it properly.

Mar 17, 2012I go into System Preferences->Dektop & Screen Saver. As the program "loads" availabe image sources and such I get a pop-up requesting a password to my secure disk image. Yes, I have a secure disk image in my home directory. Yes, the secure disk image is currently "locked" (Not mounted in finder).
I click cancel (a few times, probably 2 maybe 3 times) and things continue along fine. I select a photo source that I want for a screen save and exit peferences. I then go an start the screen saver (I'm using Hot-Corners). I get the message "Looking for pictures....." for , well...basically forever...
Sure enough I touch the mouse to leave my screen saver and there is the pop-up again. Asking for me to unlock my secure disk image.
I thought this might be related to Spotlight. I tried reading several threads and have gone as far as taking my entire hard-drive/volume and putting it into the "Privacy" tab under spotlight.
how I might get it so the "Desktop & Screen Saver" stop prompting me to unlock my secure disk image? (WITHOUT having to make sure the disk image is unlocked before I sleep my screen or open the screen saver utlity) As always, I am only speculating that this is Spotlight related so that could be a red-herring....

OS X :: 7 Pass Secure Erase - Good Enough To Return Hard Drive?
Jan 16, 2009So I may have one of the Seagate hard drives that are failing badly. Haven't heard back from Seagate to see if my drive and firmware is bad, but since I just bought the drive, I'm thinking of returning it.I'm in the middle of a 7 Pass Secure erase on it (1TB). Do people feel comfortable returning a drive after doing that erase? Or should I just forget about it and destroy the drive and chalk it up to a loss?

Apr 11, 2010I am considering purchasing diskwarrior but want to make sure it can help my situation before I purchase it. My imac will not boot from the internal hard drive (Intel processor) When I use disk utility to try and repair the disk, I get error messages and it won't repair. I can see the HD but cannot repair it. When I connect using target mode with my mac book pro, the hard drive does not appear on my host (macbook pro) computer. I have reloaded OS X (Leopard) onto a firewire external drive and can boot my imac that way but I can not find my original internal Macintosh HD. Will disk warrior be able to help with this scenario. I would really like to access that internal Macintosh HD and retrieve my files.
View 3 Replies View RelatedOS X V10.7 Lion :: Disk Utility Can't Repair Disk (1 Partition) On External Hard Drive
Apr 24, 2012I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper!
Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'. And it needs to be reformatted. It's become a read only disk. When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question. I also noticed that there are a lot of files with "date created" being the same date in 1969! These files may be letters I've written or photo's I added to that partition within the last few years.
I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure. Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state! Does this sound right, that I have to reformat the entire external hard drive? And how do I get the read-only files back to their original state.

OS X Leopard :: Disk Write Cache Corruption On External Hard Disk?
Feb 15, 2011Recently I purchased an external hard disk, to put all of my pictures of my baby due to space limitations on my internal laptop drive. Since my Canon camera 10 megapixel pictures take up a ton of space this was occurring at an alarming rate. My intention was also to back up to DVD but never got to it. This is both a comment and a question.
Now said baby, is getting really good at pulling cords etc. He managed to do this on the external drive firewire cable. As far as i know the drive was not in the process of actually writing. However, after a few minutes and trying to re-plug the drive the OS crashed with a Grey Screen of Death hardware error that tells you that you need to push the power button..
This apparently corrupted the drive's directory. Upon reboot the drive would not mount. Since there were time machine backups on the drive too Diskwarrior was not able to reconstruct the drive in the built in memory available on the computer. Time machine stores millions of files and Diskwarrior apparently wants to keep it all in memory at once. Since my computer has 2GB you would hope that would be enough but apparently not. So that failed. Other utilities seemed to be able to find the files but not restore the directory. I also took it to the apple store they were not able to recover it.
I have to say this is extremely distressing, and hard to believe that a simple accident like this could cost the loss of thousands of pictures. I did send it to a rescue company but that was expensive but I think apple needs to do something about this situation.
On Windows there is a way to disable the write cache for external drives. This is not available for Mac OS X. This would prevent this rather common occurrence of a plug accidentally becoming disengaged when the drive is not in the process of writing. This reduces the odds but I still think apple, in order to become clearly superior, needs a better solution.
I know Apple has experimented with ZFS would this not eliminate this possibility of this kind of disaster? Is this in Snow Leopard desktop? I know they are thinking this is a business customer focused technology but clearly if it can eliminate this kind of thing then I think it is extremely useful to their non server customers. Perhaps there are other ways of dealing with this issue but ZFS is designed to deal with these issues. HFS+ is extremely fragile to disk corruption.
I know my situation is not that uncommon and this is not the first time this has happened to me with an external drive. You would think I had learned. I hate to think of how many other people have had the same thing happen to them.

MacBook Pro :: External Hard Drive - Disk Utility Can't Repair Disk
Jun 27, 2014I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:
Verify and Repair volume “Seagate Backup Plus Drive”
Checking file system
Volume repair complete.
Updating boot support partitions for the volume as required.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive?

OS X :: Disk Utility Screwed Up External USB Hard Disk
Aug 6, 2010I have an external 500GB Freecom USB HDD with two Data partitions on it (FAT32 and NTFS). With a Windows tool, I made the two partitions smaller in order to free up some space (ca. 200GB) for an additional Mac OS Extended (Journaled) partition. This partition I wanted to create with the Mac OSX 10.6.4 Disk Utility. When I pluged in my USB HDD in my new iMac it mounted the two partitions, NTFS and EXT32 and the Disk Utility tool also showed the free (unpartitioned, almost 200GB) space on the HDD. Then, I chose to create a new Mac OS Extended (Journaled) partition and let the tool do it. ...which I probably shouldn't have done. Disk utility stopped and showed an error message saying that it cannot read the partitions anymore and that it needs to be closed. No partitions can be mounted anymore since then on this HDD. Here is the logfile entry of Disk Utility (unfortunately, it's in German):............

Dec 11, 2009whenever I run Time Machine on my PowerBook G4 (1.5 Ghz / 1Gb RAM / OSX 10.5.8) it will eat up GB's of hard disk space while 'preparing the backup'.

Does Time Machine use the space to generate some temporary files? Any ideas how I can get my disk space back
