Try a more heavy-duty disk utility such as Disk Warrior. If this doesn't work, the files you have on there are close to being toast. You would have to recover them with a utility such as Data Rescue II (and then spend days figuring out which file is which and which file is worth keeping). Otherwise, just reformat your drive with the "write zeroes" security option to map out all the bad blocks.

How do i erase all my personal data on my mac mini?


That depends on what operating system you have. If it's 10.6.8 or older, you need the operating system install discs that came with your computer. Just put it in and restart the computer. When you here the start up chime, press and hold the C key to boot from disc. Then in the utilities bar on the top, select disk utility and then the top left hard drive icon in the side bar do the disk utility application. Go to the erase option on the right portion of the screen and make sure the erase option says MAC OS JOURNALED and click erase. That wil remove all data off of the hard drive including the operating system. After that is done, you can reinstall the OS with the disks.

if your OS is newer than 10.6.8, hold option after the apple start up chime, this will let you select bootable drives that the computer detects, there should be a recovery partion, select that and repeat the steps in disk utility I mentioned above.

Time machine on MAC 10.5.8 will not open; error message -43


Hello,
error -43 fnfErr: File not found
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."

http://docs.info.apple.com/article.html?artnum=106214

Then Repair Disk on the external drive.
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

If TM display doesn't even show up, see this...

When I try to connect my Seagate Free Agent Pro backup drive using USB to my new Sony BDP S570 DVD player I receive a message USB device connected is not support. It worked with a Western Digital drive


So I would suggest a few things for this issue. First check the format of the drive you are trying to plug in. You can do this on your Mac by using Disk Utility (Applications - Utilities - Disk Utility). Plug in the drive and open Disk Utility and click on the partition. At the bottom of the Disk Utility window it lists the information about the drive. You are specifically interested in the "Format" item. If your drive is formatted Mac OS Extended or some other Mac format you probably cannot use it on the Sony Blue Ray player. Most device look for and are only compatible with Windows type formats. For example, NTFS or FAT32. The best way to test if this is really the problem, or a systemic problem with the BR player would be to pick up a USB jump drive somewhere (they are cheap if you don't have one just laying around.) Format the jump drive to a FAT32 or NTFS file system using Disk Utility. Copy the files you want to view to the jump drive (Be sure to check the file type compatibility chart on the Sony website or in the manual and make sure what you are trying to view matches those types.) Plug that in and see if you are successful. Also there was a few notes on forums that Sony doesn't support actual hard drives on the BR players which would suggest that they only support Jump drives and FAT32 because of the file size limitations it brings. Try this and let me know how it goes. Attached is a picture of my Free Agent drive formatted for Mac in Disk Utility .jp_2010.jpg

Having removed a cd screen is blank and seems as though a cd is still running a question mark is flashing


The flashing question mark, indicates that the system cannot see the operating system.
Check for a failing hard drive
Trying booting from the Mac OS X install disc. insert the Mac OS X install disc. press the start button, while holding down the "C" key on the keyboard
Once you are running from the disc. go to Disk Utilities select the hard drive click the "repair permissions" button at the bottom.
If you get any red errors listed or it doesn't seem to finish repairing the permissions you have a failing hard drive and it will need to be replaced.
If this process finishes without any issues you will have to reinstall your operating system.

Very slow mac mini 60gb


There are quite a lot of reasons that may cause a Mac Mini computer running slow, but generally two factors: hardware part & system part. For hardware part: I guess it's OK if your Mac Mini is not that old. For system part: there might be a lot of junk files, caches, registry errors... out there which largely slow down any Mac machines. about 80% slow Mac caused by this reason, if so, try cleaning the system.

Hi. My mac mini started to get really slow. Now I notice the hard drive is filling up with something. 95 Gb was available - now only 75. iANtivirus did not pick up anything. Though it feels like a worm to...


It sounds like something is either corrupted on your system or one of the files in your mac mini may be suspect. What I would suggest is get your system disc boot the mac mini down holding down the c key on your keyboard. Remember to back up before you do this. Once it is booted up go to the file menu and find the disk utility. Open up the disk utility and first of all repair your disk permissions and then run disk verify and if an error comes up repair it.

Also download Onyx from this website http://www.switchingtomac.com/tutorials/keep-your-mac-running-smoothly-with-onyx/ which also talks you through the method of using it. I use it every month just to keep my mac in tip top condition.

If neither of these pieces of advice work. I would suggest installing a clean system. Again with the system disk in your computer restart your machine with the c key held down on your keyboard. Choose to do an install but remember to select preserve users. This will give you a clean instal with your files and preferences intact.

Hope this helps.

Some of the start up files have been corrupted or are missing. Start up from the OSX system disc and them run Disc Utilities from the installer toolbar. Check the hard drive for errors. Repair any errors if they are found. If it's not possible for Disc First Aid to repair the hard drive you will need to replace the drive and re-install OSX.
