Is there a program that will catalog the two and show me the differences? I seem to remember such a program in the old classic days.

OS X V10.6 Snow Leopard :: Copying Files Between Hard Disks Interrupted By Error Code -36

Mar 18, 2012

This error probably indicates a hardware problem or some system malfunction. I usually try to find out what exactly went wrong to take measures to avoid the repetition of the same problem. Exchanging the HD and restoring the sytem may be the quicker solution, but I would miss an opportunity to reconfigure my system to make it more robust. 

The system in question is a MacMini (Model A1347) with Os-X-Server 10.6.7. and 2 physical HDs: HD1 has 2 Partitions, the smaller for the server OS, the larger for the Shares (We use the MacMini only as a file server). HD2 is not used (was kept in reserve for cases like this).  

That there may be a problem manifested itself first when the mounting of the shares on HD1 became suddenly slow (within 2-3 days) and eventually failed. I first tried to copy all the files from the shares on HD1 to HD2 before attempting any repair actions. Most of the files copied properly but a few failed with error (-36). Those few can be restored from backups, so there is no data loss. Remains the question, what went wrong?  

It may be pure coincidence but just before the File-Server failed there was an attempt to upgrade a 3rd party software on one of the clients (17'' MacBook Pro / OS X 10.6.8) to a newer version. Could be that new version was part of the problem because the data files of this 3rd party software are stored on one of the shares on HD1 and the data file format has been changed between the versions. For obvious reasons I need to make sure that this data file conversion was not the cause of the problem?

1) first check the HD1 with a different tool than DiskUtility (It thinks the HD1 is in perfect shape), TechTool Pro or DiskWarrier comes to my mind, any reason to prefer one over the other? 

2) Hopefully those tools can reliably test whether the HD1 is damaged or not. If it is the former the HD1 replacement option is the way to go and there is no more reason the 3rd party software may have been involved. However if HD1 is not damaged I'm left with the uncertainty of what exactly lead to the problem..? 

3) Is there any check I should do before I just re-format the HD and re-install the OS and switch back to  an earlier version of the 3rd party software to be on the safe side?

OS X Server V10.6 Snow Leopard :: Mounting RAM Disks As 'notremovable'

May 12, 2012

I am replacing my G5 (10.5) Xserve with a late 2008 Xserve (10.6). This server is primarily a web server, with a small amount of mail traffic.I keep my 'webfolder' on a RAM disk. All of my pages are dymanic php/mysql, so they can't be cached. But reading from RAM is so fast, you'd never know it.This is the command I used in 10.5 to create a 1 GB RAM disk at boot: [code]/usr/sbin/diskutil erasevolume HFS+ "web-ram" `/usr/bin/hdiutil attach -notremovable -nomount ram://2200000`[/code]Not the "notremovable", that flag makes the system treat the mounted disk image (or in this case, the RAM disk), like a real physical disk, and not a mounted disk image. When you use this flag, the ram disk will actually show up with a regular hard drive icon. Without this flag, it shows up as a white disk image.But this flag doesn't work in 10.6. According to the man page, it's still there. But when I use it, I get permissions errors. I am using it with sudo (from the command line, or as root via lanuchdeamons). As I look closer at my errors, It appears that what might be happening is that the diskutil command is being run as root, but the hdiutil command inside of it, is not.

Anyway this is about more than just the icon. When the ram disk is mounted as a real disk, its harder to eject, which is good because it's my web folder and I don't want it going anywhere. AND when its mounted that way, I can use time machine to back it up. Which works out to be a great system for that.

My TM backup files are getting unnecessarily large so I would like to delete them and rescan my computer again.However, I don't want to risk deleting my TM backups and have the computer fail, so I wanted to copy the backups temporarily to a spare disk until the new backup had been completed successfully.So can the TM backups be moved just like any other file?

OS X V10.6 Snow Leopard :: Recovering .dmg Files From An Accidentally Reformatted External Hard Drive?

May 3, 2012

I went to make a copy of an important drive and accidentally re-formatted it (re-formatted mac journaled, originally mac journaled).  The drive contained a bunch of important disk image files which I need to retrieve whole. I'm fairly confident that the files are still there and only the  table information got overwritten, as the re-format took about 30 seconds.  None of the  recovery software I've seen however, can retrieve .dmg files, or such large files (these are up to 32 gb each in size).how I can retrieve these disk image files?

I am trying to find out how many files I have on my Internal HD so as I can match them to the copied files on my external HD before I re-format to make sure they have all copied.

My external is MS-DOT (FAT32) and the internal OS Extended Journaled giving me a difference of roughly 7GB, I can only bring up the capacity, available and used information.

OS X V10.5 Leopard :: Determine What Sharing Services Are Running?

Feb 19, 2012

I have an old G4 tower and no monitor for it. I wanted to go through old files and I used to just login remotely (screen sharing, SSH or AFP) and do what I need. I don't know why, but now no services seem to be running. I know for certain that the computer is connected to the LAN network. Basically, I'm trying to find out what services may be running. I'm not trying to get past any security, just access my files. If it's stuck at the login window, will no sharing services start? I guess not, since no user is logged in.

OS X :: Replacing Hard Drive - No OS Disks

Apr 14, 2009

I am wanting to replace the hard drive in my macbook but I don't have the os disks that came with the computer (I've recently moved and they're beyond lost). I've read where apple can send me replacements (I assume I'd have to pay for them). Can I get the leopard upgrade and use that, or it just that, an upgrade and I need osx already on the computer. I don't care about backing up anything, as theres nothing on it of any importance, all my music and photos are on an external hard drive.

MacBook Pro :: It Keeps Breaking Hard Disks

Jun 13, 2012

MBP Mid 2009


8GB Ram


The problem started with my MBP freezing about once per day (sometimes spinning wheel, sometimes complete unresponsiveness). After doing a hard reset, I would usually be given the grey screen with stop sign, and the machine wouldn't boot. Resetting the PRAM would fix this, and it would boot OK. This was going on for a few weeks (I did disk checks which came back fine).

Then a couple of days ago the machine froze (unresponsive), I did a hard reset but just got the chime and grey screen - no Apple logo, no spinning wheel, no stop sign. Nothing. I did PRAM and SMC resets, but still nothing. I tried booting safe, safe verbose, hardware test, single user - nothing would work; just chime and blank grey screen. So I thought my OS installation had died.But when I tried to boot to the Lion DVD, still nothing - grey screen, the DVD would spin up, then spin down to a stop. I thought it might me faulty RAM, but not having any others to try I just swapped the two pieces over. Nothing.

Then I plugged my external 500GB HDD in to the USB (which was the machine's original internal HDD) and suddenly the Lion DVD would boot. So, the internal 1TB was dead. I put the 500GB back inside, booted Lion DVD successfully, formatted the HDD and started the Lion install. This failed with an error message 'the support files can't be copied - restart to try again'. So I restarted and in disk utility it said the HDD S.M.A.R.T was failing and it had a serious fault which could not be fixed and needs to be replaced.The 500GB disk was working fine and had had very little use since being replaced by the 1TB in January this year (the 1TB was brand new in January). So it seems odd that the both decided to fail one day after each other.

MacBook Pro :: Can See Hard Disks In USB Enclosures / But Not Internal

May 16, 2012

I have a mid-2010 macbook pro 13". The other day, it crashed on wake-up, and would not boot. I had a OCZ Vertex SSD boot drive, and the OEM hard drive in an optibay enclosure (replaces the optical drive and used only for data). I used this setup for one year with no problems. After much troubleshooting, I found that I could see the SSD drive by booting into a recovery partition that I have on a USB stick, and putting the SSD in a USB enclosure. Then disk utility could see it, but not mount it. The label on the boot partition was "lion", but it changed to "disk1s2". I was able to repair the drive using disk utility, and then boot from it using the USB enclosure.Once booted, I could still see the OEM hard drive with no problems. So I powered down and put the SSD back inside the case and rebooted. It booted in safe mode, but it booted fine. The next time I rebooted, it would not boot. I swapped the OEM drive and the SSD drive, and then the sytem booted with no problems and I was able to use both drives.

One day later, I noticed my OEM drive was no longer mounted in OSX. I took it out, put it in a USB enclosure, and OSX could see it fine. There were no errors on the disk. I put it back in the macbook and reboot but OSX couldn't see it.So, the primary SATA port seems to be working intermittently. Three times now, a drive has stopped working on this port. Each time, I could use the drive in an external enclosure (or using the other SATA port normally used for the optical drive. Does anyone have any ideas? Could it just be the cable?I'm trying to make this computer last at least another month or so because I need to upgrade to a larger model, and am holding out for the 2012 release.

Mac Mini :: What Is Done With Damaged Hard Disks When Replaced By Apple

Jun 29, 2012

Wondering if anyone knows what the security policy and process is that is followed by Apple when a damaged hard disk is replaced by Apple. Is the disk destroyed, or demagnetized. How do we know that the data on the disk is will not be accessed and copied anywhere? Is there a stated policy document available somewhere in the Apple Store that discusses this?

MacBook Pro :: Dual Disks IMac Style - Technically Hard

Sep 16, 2010

I know it has been discussed previously in terms of desire to see it happen. But my question is how hard would it be for Apple to accomplish this?

The optical drive takes up a lot of space, and also connects through Sata, right?

OptiBay and others have hack solutions, do surely Apple could make an elegant one for us.

The mini has dual disks. The iMac also has dual disks.

Any reasons as to why we're still waiting to see this in a MBP?

OS X :: Use A USB Hard Drive With Snow Leopard And Xbox 360?

Sep 8, 2009

Ok so sometimes I like to watch HD movies on my Xbox from my external usb hard drive that is formatted HFS+. I heard that formatting with Snow Leopard frees up that extra bit of HD space so I thought i'd try it. Well it sure did free up the space - after the erase/reformat there was 249.4 GB out of 250 GB (normally after a reformat there's only 232 GB out of 250 GB). So I go to plug the usb hard drive in my xbox 360 and it didn't recognize it. WTF? So then I tried to reformat it back to HFS+ with Macdrive on Windows but it still isn't recognized by the xbox.

I am trying to defragment the hard drive using snow leopard but I get the following message:You cannot use this algorithm on the selected volume. Off-line algorithms need to unmount the disk so you need to boot from a different disk, partition, computer or CD/DVD. Alternatively, use the Quick (on-line) algorithm.How would I do this without doing a quick algorithm? Basically how do I unmount the disk or boot from a different disk or DVD and run this program, iDefrag.
