OS X :: Two Identical Hard Drives Not Calculating As Identical
Sep 19, 2009
10.5.8 Power PC G5
I have two identical external firewire "archive" hard drives. One serves as a safety copy of important data and the other serves as a safety of the safety. Both drives are identical models of identical size purchased at the same time, installed in identical enclosures, formatted the same way and when originally formatted showed an identical amount of available space on each drive. When archiving is needed, important data is copied to both drives. So after the double copying of data, they have the exact same material. They are now about 1/2 full with supposed identical files.
However, in the finder one drive shows about 3 gigs worth of available space more than the other. I have used a couple of utilities (such as Toast's compare utility and Disk Warrior) to compare the drives and see what is causing the discrepancy. While they do have the most minor differences in some hidden files, the difference is only a few megabytes and nowhere near the 3 gig discrepancy.
Any thoughts on why there is such a big difference in finder's calculation?

I have 2 WD Caviar Black drives that are installed in my Mac Pro. Both show the exact same part number in Disk Utility, both are less than half full, both verify fine with Disk Utility. However one shows 125-130 MB/s RW with AJA and the other only delivers 90 MB/s. What gives? Just a sub-standard drive? THey are in adjacent bays in the MP, used as is - nothing changed. They are OEM drives thru Amazon from a few months ago. Both were erased and formatted prior to putting them in the MP a few weeks ago.

I should be getting my iMac in the next few days and more than likely going to get the 24" ACD, so I can dual display it. I know there is a difference in height, so going to VESA wall mount the ACD. I know the 24" ACD is LED and a slightly different screen to the iMac, the question I have his will I be able to get the screens to look pretty much identical i.e. brightness, colours or will I have to get something to calibrate the screens?

I have a g3 slot loading Imac, which I am reusing as a computer for a family member who is visually impaired. I have bought a 22" monitor that can display a resolution of 1680x1050. but I can not display more than 1024x768. Another problem is that I can't get it just to display on the external monitor, it uses both monitors with identical pictures.

I have two MacBook Pros running 10.7.4. I wanted to copy one iPhoto library from one device to the other using a new Thunderbolt cable. The file is approximately 60GB. When I copy a small file of 1.0 to 2.0 BG in size, the transfer is incredibly fast -- as in seconds.
When I try to transfer the large file (60GB), the transfer is very slow, and Finder says it will take 12 hours. Oh, and I am not running any anti-virus software.

MacBook
Pro, Mac OS X (10.6.8)

I have a curious question: Does Apple Mail filter identical mails?
More precisely, I am expecting a number of mails that are identical, except they arrive from different mailing lists.
However, I can only see one of them.
So, I was wondering whether Apple mail has some "intelligence" built in that would filter out the others.
Info:
MacBook Pro (Retina, 15-inch, Early 2013), OS X Mavericks (10.9.2)

Why do they both exist? My best guess is just that they switched to iTunes Library but maintain an identical iTunes Music Library file for now for compatibility (since the XML files exist so 3rd party apps can access the iTunes library).

I understand why "Open With" includes both old and new versions of updated apps. Fine. But how do I CLEAR the list and prevent this from continuing? (I'd expect it to offer a "Clear List" option at the bottom. It doesn't.)
Info:
MacBookPro, OS X Mavericks (10.9.1), 1TB int HD on 10.9.5 (not 10.9.1)

Rule #4 of the AppleID password restrictions states "Not contain more than 3 consecutive identical characters" -Your rule is actually "Not contain 3 or more consecutive identical characters". "more than 3" would allow 3 consecutive characters, but it turns red ( invalid ) if this is attempted. Also, rule #1 states "Have at least one letter", which in standard English would include Upper and Lower case letters, but Apple's rule requires it to be "Have at least one lower case letter", while rule #2 "Have at least one capital letter" does correctly specify requiring at least one upper case.

I have an external drive that's not showing me all sizes when selected in the list view options.
Anyone know why this is happening?

I'm looking at the specs page for the MacBook Pro and it reads this...
Your MacBook Pro comes standard with a 5400-rpm Serial ATA hard drive. Choose a hard drive with a faster speed for greater performance. Or you can choose a solid-state drive that offers enhanced durability.
Basically suggesting that the HDD option has a performance advantage over the SSD, but is this the case? I always thought SSDs could read & write quicker because they use solid-state flash memory as opposed to hard disks.
I want to go with the 256GB SSD but I want to know how it ranks in speed.

I have a Imac 20 with a small 3.5 hard drive and I have bought a bigger 360 gig 3.5 hard drive to replace the old one. I have the new one in an external case with USB 2.0 right now. Is there some way I can transfer the entire contents of the old hard drive on to the new one and then swap out the old drive with the new drive and not miss a beat?

I have to hard drives in my powermac. And I am running out of space with the one that has the OS on it.
I want to make the 2 internal hard drives i have appear as one so i can still install and use things that say "must have mac OS installed on this drive to use" or whatever.
i've heard of people using RAID to join them, but i want details on how i could do this.

I recently realized that my TM hasn't successfully backed my system since April 21. At the time I noticed this, the TM disk was very low on free space, even hitting 0% free.
I powered off my mac, and even powered off my disk. Waited a small bit. No good. I then manually deleted some old folders, and still no good. (I'm thinking that may not have been a good thing, but at this point I don't see the downside.)
I'm thinking of completely scrubbing that disk and starting TM on it as if it were a new disk.

I'm hoping someone more knowledgeable than myself can help me out. I have a 2006 Intel-based Mac Pro:
Processor: Two 2.66GHz Dual-Core Intel Xeon processors
Ram: 6GB (two 512MB) of 667MHz DDR2 ECC fully buffered DIMM
HDD Bay 1: 250GB Serial ATA 3Gb/s; 7200 rpm; 8MB cache
OSX: Tiger
I need to upgrade to Snow Leopard to be able to use newer Leopard & above only versions of software ie FCP, Aperature, etc.
The issue is that I would like to keep the Tiger OSX as I run Pro Tools LE 7 on it. Upgrading to Snow Leopard would render Pro Tools LE 7 incompatible and I would have to buy it again.
So here's what I'm thinking. I would like to install a secondary HDD in Bay 2 and install Snow Leopard on it.
Is it possible to have OSX Tiger on the HDD in Bay 1 and have OSX Snow Leopard on the HDD Bay 2? Could they each be a different startup to be selected via System Preferences or at bootup? I would only want to run one OS at any given time.
If so what would be a workflow for installing the 2nd HDD and setting it up with OSX Snow Leopard.
Also, compatible hard drives for the 2006 Intel Mac Pros seem to be harder to find now. I called Apple and they no longer sell any compatible internal HDDs.

I'm planning on getting a Mac Pro with multiple hard drives and was thinking about having a main drive for Leopard and documents, one for music, one for video and another for Windows. I was just curious to see how others have theirs set up and any if there is advice to be shared.

I'm having an issue that I can't figure out. Hopefully someone here will have an idea or two. I need to create a list of specific weekdays with dates from on out. In other words, I need to know the dates of all Sundays and Tuesdays from 12/1/10 to 12/31/12. Ideally, I'd like it do be in an excel or csv format so I could easily manipulate the data. Any ideas on how to do this easily?

I've finally gotten Snow Leopard on my Mac Book Pro, after jumping through hoops to get there - Disc not GUID, then when it was, SL not believing that the disc was bootable.
Due to this, I nuked the hard drive, installed SL and then restored all settings and apps from my latest time machine back up, whilst physically cabled to my Airport Extreme Base Station. Whilst I left it do that, it finished the restore, and also did a couple of hourly back ups. All hunky dorey so far.
Now that I'm using wireless, I notice that Time Machine kicks in as normal to do a back up. The icon starts whizzing round, and it starts calculating the changes to back up. But that's it. It progresses up to 99%, and then just sits there. I've left it like that for several hours, to see if it's actually going to complete, but nothing happens.
Is there something I can look at to see if I can prod it into action?
My backups go to a Drobo hanging off a Power Mac G4 on FW800, physically networked to the AEBS.

I would have thought, given the pace of innovation, that we might have had hard drives larger than 1 TB by now. Has anyone heard of any potential rumors?

Looking at Seagate site, even newegg, the hard drives for mac are incredibly more expensive. I doubt the interface is different, so the only other option is how it is formatted.
If the drive is formatted differently, at an extra cost, I am curious if OSX is capable of formatting externals on its own? Can I buy a standard drive and format it natively in OSX?
I only ask, because after coming from Home Premium, several hardware utilities are non-existent.

I have a 15" MBP with 256ssd installed and a 13" MBP with a 250gb 5400 drive. I prefer to use the 13" as my main computer and want to take the 256ssd drive from the 15" and put it in the 13". Then take the 250gb drive from the 13" and put it in the 15" How hard is this to do? I've not done something like this before. Since I'm swapping an ssd with a regular hd is it as easy as following the instructions on this forum, remove the screws and swap the drives? After that's done I'll need to overwrite the 15" software and load the OS and drivers for the 13" on to the ssd drive. Is that as simple as taking the restore disk for the 13" put it in the drive and reinstall the OS? Or, should I just take it to the local authorized Apple Dealer and have them do it? (We don't have an Apple store nearby.

When I was on OS Tiger I had all my iTunes content on an external drive to free space on my iMac, content being 224gig on a 300g external HD. I'm now on Snow Leopard and would like to use the Time Machine facility but it says I don't have enough room to carry out.I still have 224g of iTunes on ext and I have 198g available on a 300g Mac HD. Can I split the iTunes content over the two drives i.e music on one and movies on another? If yes, how? Or, to use Time machine effectively should I look at other options?

This is one of the things I haven't figured out how to do yet on my mac. I miss this feature which was so easy in windows. Select multiple files and click properties and you get a file size count. If you do the same thing on a mac you get a number open for each file. If you need a cumulative total quickly its a pain in the butt to add each file.
What am I missing here?
Also, any way to display file size at the bottom of a finder window? When you click a file, it says "1 of X selected" and the amount of hard drive space free which is cool, but file size at the bottom would be nice to have.

To begin with, I am using a WD (Western Digital?) external hard drive that I back up to wirelessly through an Apple wireless router. The hard drive is divided into three sections - one for each of two iMacs and one for my laptop. The iMacs back up automatically, but I manually start Time Machine for my laptop since it is not always on and not always in my home. I am having problems only with the laptop backing up - both iMacs back up to the HD just fine. Also, if it matters here, my laptop's internal HD recently crashed and I got it replaced at the Apple store, and restored it from a backup that did work two weeks ago.
Basically the issue is that I try to initiate Time Machine now with the proper partition opened on the external HD and it reaches 99% after a slow process of "Calculating Changes" and freezes there. This is true wirelessly and if I jack the laptop into the external HD directly with the cord. After several minutes, the fan starts up. After what feels like a pretty long time, it suddenly starts over in "Calculating Changes", reaches 99%, and once again freezes.
Does anyone have any idea what the problem could be? I am hesitant to blame it on getting a new HD, but that IS the only major thing that has changed since I last backed up. I am pretty sure it is a software issue since both iMacs back up with no problems.

Our Mac Pro crashed, and upon reboot, both the internal raid as well as the external firewire drive that happened to be plugged into the machine at the time, are both 'locked' and we cannot unlock them. We've tried toggling the 'user and permission' choices from the 'custom' setting that they are now showing to read/write... and it just snaps back to 'custom'!
Same if we try to change to just READ or just WRITE...etc...nothing...
Just a gray icon of a LOCK under the icons of the drives, and a warning anytime I try to access them, saying I don't have permission to do so.
I even unplugged the firewire drive and plugged it into another computer and it does the same thing!
And I even made a new ADMIN and tried changing it with that, to no avail.
Everytime I look at either of these drives, those 'users and permissions' toggles are back at 'custom' and they just won't relent!
Oh, and I also flashed PRam and 'Repaired permissions' on the boot drive [yes, the boot drive is working fine]
I need the media that is on these drive... a ton of video media on the internal raid, specifically... So I can't just repartition them from boot disk.
