Hard Drive In 2nd Internal Bay Sometimes won't mount
I recently installed a second internal drive in my computer. My main problem is sometimes the drive won't mount. If I turn off the computer for a while it will finally mount but that's not good enough. One day it may not mount at all. What I want to know is; does anybody else have this problem and if so, how did you fix it?
Or better yet, is there a command I can use in Terminal to mount the drive?
G5 Dual 2.5 GHz; 4.5 Gig Ram; Logic Pro 7.1.1 Mac OS X (10.4.5) 2nd internal 160 gig hard drive installed
Barry, make sure all of your connections are seated properly. I had this same problem with a SP 1.8 PowerMac, and the problem was that the cable was not seated well which disrupts the signals from getting to the drive. This caused the drive to mount sometimes, and not mount others. Check connections at the drive and motherboard.

External Hard Drive Doesn't Appear on Desktop / Won't Mount
I have an external hard drive that is used as a server for 3 computers . . . it is hidden from the Desktop.
The "home" computer is running 10.8.5, and the others (which also have the hard drive hidden) run 10.9.5 & 10.10.1.
I can access the drive by going to Go > Recent Folders, and also from aliases to the drive I already have on my Desktop.
The drive shows up on Disk Utility, and was fine when I verified the disk.
I also reset the SMC and PRAM, with no affect on the hidden folder.
The Thunderbolt connectors and Firewire 800 converters all seem to be in working order.
I've seen some fixes out there for the same problem with users running OS X 10.9.3. They've used a Terminal command to reveal the hidden files. Am not sure if the code for 10.9.3 will work for my 10.8.5.
Someone, please help!upgrade to latest system, that computer will accept, then try again

I have an early 2008 Mac Pro and want to install a 3TB internal hard drive. Is this compatible? The manual indicates 1 TB per bay, but I have already installed two 2 TB hard drives in two other bays, and have had no problems. Any suggestions?
RE: SATA Bus speed:
Typical Rotating drives available today, whatever their SATA spec, can source data off the spinning platters no faster than about 125MBytes/sec.
SATA 3 is rated at 6G bits/sec, which theoretically is about 750 Mega Bytes/sec
SATA 2 is rated at 3G bits/sec, which is theoretically about 375 Mega Bytes/sec
SATA 1 is rated at 1.5G bits/sec, which is theoretically about 187.5 Meg Bytes/sec
None of the SATA Busses is a bottleneck for consumer Rotating drives you can buy today. Trying to speed up the SATA Bus will not provide any real-world performance increases for Rotating Drives.

Multiple hard drives in a single bay problem
Greetings,
Here at work I recently had to install two additional hard drives into a PowerMac G4 1,25 GHz (FireWire 800 model I think). Inside both of them there's data that might be used in the future.
The two hds specifications are the following:
1) Hitachi Deskstar ATA/IDE 123,5 GB taken from a older, broken G4 Quicksilver PowerMac.
2) Maxtor DiamondMax Plus 9 160 GB / 133 HD taken from a broken Lacie firewire external hard drive.
After correctly plugging BOTH hard drives in the lower bay of the G4 and booted the machine, the additional hard drives would not show up, not even in Disk Utility. I removed one hd from the lower bay, turned on and the computer read the remaining additional hd without problems. I swiched the extra hd back with the other, and it would work perfectly. Since both HDs are compatible and working, I'm wondering, why if I plug the 2 HDs togheter in the same bay they won't work? What should I do?
I also tried putting one of the HDs in the upper/back bay, togheter with the original system HD, but the result was that the computer freezed at boot, even when holding the alt key to choose the starting disk.
Now I'm assuming that the computer can't hold more than 2 internal HDs, but then why put 4 HD slots? Am I doing something wrong?
Thanks in advance.I agree with Allan. Both drives probably have their configuration jumper set to Master (the default for drives installed in external enclosures), which is why each is recognized individually when connected, but not both when simultaneously connected. For simplicity and ease of installation, you can use the Cable Select setting for each drive. Otherwise, one drive can be left as Master (or Master w/Slave present) and the other drive set as Slave. Systems that support Cable Select also support Master/Slave, provided that you connect the drive configured as Master at the end of the ribbon cable and the drive configured as Slave to the middle connector. The drives' labels should have jumper info printed on them. If not, consult the manufacturers' web sites for specific details.

G4733DA w/ 4 internal HD's sometimes won't mount/boot to alternate HD-Why?
I own a G4 733 DA w/ 4 internal HD's which sometimes won't mount/boot to an alternate HD on an internal Sonnet PCI controller card (position 1 only).
I can also boot to either of the 2 HD's on the sonnet pci controller card (even though neither shows up on system profiler in OS X.4.10). One of which is a Seagate 7200rpm, 400GB which I am currently booted to right now (it's in slot 2 of the sonnet pci card and works fine) However, at times the HD on slot 1 refuses to mount on the desktop. When I remove the same hard drive it mounts fine on an ext. FW enclosure.
Is it possible that slot one on this sonnet pci card is starting to go out? And how do I know for certain since neither of the HD's on this Sonnet pci controller card show up on system profiler? Is this normal? Shouldn't every hard drives show up in Apple's system profiler? Even the ones on the pci controller card? Should I just try a separate HD on the same slot and see what happens? I have all of the drives cloned to a much larger ext. FW HD so I'm not really worried about loss of data since I have all drives backed up to ext. FW HD's.Neither of the HD's on this Sonnet pci controller card show up on system profiler. Is this normal?
Yes, it is normal. Earlier versions (before Panther) of System Profiler would show the drives connected to a Sonnet PCI controller, but current versions just show the controller itself. Disk Utility should show the drives.
Each port on the Sonnet card can have up to two drives, one Master, one Slave. The Master should be at the end of the cable. If a Western Digital drive is alone on a cable, it should be set to Single. Drives on the Sonnet card that are set to Slave are not bootable.
Try swapping cables at the Sonnet card. If the same drive has problems, then it is the drive or cable. Try swapping just the cables. -
I bought a new external hard drive for backups, but time machine won't do a full back up.
I think it is remembering backing up onto previous external hard drives, which I don't own anymore. How do I do a new full backup?
When I bought the new (used) iMac, I also bought an external hard drive for backups. It worked fine, but my husband stole it.
Then I bought a new external hard drive (Seagate) and it worked fine for three weeks, then died.
So I just got a new external hard drive, which was put together from an internal hard drive and a hard drive enclosure.
Time machine did the first backup today, and it should have taken 9 hours like it did on the previous first time full back up. Instead, it took 30 minutes. That can't be right. I want to start over and do a full backup to make sure everything gets onto my new external hard drive, but I can't figure out how to do that. Please help.Triple-click anywhere in the line below to select it:
tmutil compare -E
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command will take at least a few minutes to run. Eventually some lines of output will appear below what you entered.
Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
At the end of the output, you’ll get some lines like the following:
Added:
Removed:
Changed:
These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot. -
i have a mac os x ver. 10.5.8 2x2.8 quad. my start up disk is almost full. can i change my start up disk from the original hard drive to an additional hard drive i added in Bay 4?
Always want to keep the boot drive with more free space than may seem necessary for performance and to function at its best, 30-40% free or even 50% is not excessive.
Ideal is to separate your system from your data.
You should always have bootable backup / clone of your system
Don't use a green drive for system or data though.
When you are done cloning system and/or data, remove the old original and keep as backup.
Then move the system drive to #1 - no matter what you want to reset the default boot volume to where the system is.

Hi! I got Movies on my external hard drive that are AVI kind and won't play on my macbook pro? When I start playing the movie a message pops up and says "a required codec is not available". I tried flip4mac, xvid, divx already and still not playing my video. need some help please!! thanks.
Although vlc mentioned above is a much more powerful and better player you could try installing Perian if you insist on using the quicktime player. It may supply the codec it needs.
Not sure why you wouldn't be able to play straight avi files though in quicktime. -
I have a desktop Mac. I bought Apple tv and wanted to connect my photos to the tv. I learned that I had to upgrade my OS as I didn't have icloud capability. I purchased and downloaded Lion. I cannot open it however, because when I go to select the hard drive to install Lion onto, the dialogue box says that I cannot open it in either my external hard drive or the internal hard drive because of the backups to time machine. I have tried the 'fix' of moving the backup folder to the trash and then putting it on the desktop, but I still can't access either one of the drives to install Lion. Any suggestions? Thanks.
The current OS is Mountain Lion 10.8.3, so I if the purchase was recent, that is what you should have.
It should be possible to see what disk space is being used by opening the Disk Utlity in the Applications>Utilities folder. It looks like both disks are set as TM disks:
If you have Time Machine backup of both the internal and external disks and want to rationalise the system to only backup one, then set the TM preferences>options to exclude volumes as required:
When you download the installer from the Apple Store (MAS) it will come up with a dialogue to run it. It will then ask which disk you wish to install the system on. Is this where you have got to, before it says they are both unavailable? -
I backed up my I-tunes library (by dragging my "music" folder to my new external hard drive. Now 6,000 songs won't play stating, "original file cannot be found." What can I do to get these songs back???!!!

My ITunes Library is on an external hard drive, however, the internal hard drive on my laptop crashed, requireing a complete re-format and re-installation of Windows XP--When I re-install Itunes, what do I need to do to make sure I do not lose all of the content on the two iphones I have, and to re-associate the library with Itunes ( i know how to change the path) but I am fearful that somehow the library link will be broken since the old Itunes installation is gone, and who knows what else might go awry.

had a new hard drive installed last month. now iphoto won't start up, popup says "you can't open the application iphoto because it may be damaged or incomplete". can this be repaired without going to the repair shop?
What installed iPhoto there in the first place? Was it the same version of iPhoto that came with the Mac? Was iLife added at a later time from a Mac Box Set? You can selectively install iPhoto, and then apply the appropriate iLife update without taking it to the shop, after removing the application, or recover it from your backup.

2nd Hard Drive...internal or external
I'm adding a second hard drive to my MacPro.
I'm looking at a 1TB internal made by MCE prostor
http://store.mcetech.com/Merchant2/merchant.mvc?Screen=PROD&ProductCode=PS1000GS&Category_Code=STORHDDT&ProductCount=3
or an external...everyone says a Lacie Extreme.
Any thoughts would be helpful
ThanksLacie Xtreme is the way to go. The idea is to liberate your machine the extra "stress". Mine have been very faithfull. If I were you I would rather have two 500s than 1TB unit. I like to have all my work backed up in a hardrive outside my system, just in case. Believe me these Lacie Xtreme 500 are flawless with the MAC. It is like having another internal HD, with the advantages of: PORTABILITY, and SECURITY. If you ever get a MACbook Pro, and decide to take all your files on the road, like mua, you just grab your Lacie and go.
P.S. I have learned from experience, when backing up files, it is better to be safe than sorry. -
Clean migration from internal drive to 2nd internal
My hardware and software have always been tidy compared to others (judging from questions posted here, elsewhere, and seeing/using other people's Macs). However, after upgrading to Leopard, a couple of quirky problems have been driving me nuts -- problems I've posted as questions here in these forums (namely, keyboard lockout after screen sharing and alias folder repositioning). Don't know if those are actually current OS glitches or if it's just my system. Also, a third party app is no longer printing certain fonts.
Now with a spankin' new hard drive arriving soon (for other reasons), I want to do a "clean install" and migrate everything from my stock 160GB, then reformat that old little drive for other uses. I figure I might as well tidy up some more while upgrading the internal HDD. It could help iron out any minor quirks in the process and streamline the MacOS.
But I've never used +Migration Assistant+ before. Don't know if it's relevant now. I've never done an +Erase and Install+ either from DVD, though I've been reading up about it. My DVD is a 10.5.1 retail version.
Question is:
*What's the most clever way to proceed?*
For example, should I:
1. Physically install new drive in 2nd bay, run +Disk Utility+ to reformat, insert Leopard DVD and do +Erase and Install+, then run +Migration Assistant+ ? This seems logical.
-or-
2. First use Leopard DVD to do +Archive and Install+ onto the current Leopard 160GB, then do physical install of new drive in 2nd bay, use +Carbon Copy Cloner+ to mirror all contents, restart from new cloned drive, then delete Previous System folder within same, then reformat the older drive? This seems more clever.
-or-
Other cleverness?I don't see the need for 2. You can do 1. or you can use CCCloner to clone the current install to the new drive and then do an archive and install on that directly. This will leave the original drive intact so that in case of problems you can always go back to it.
Do keep in mind that whether you use Migration Assistant or do an archive and install some of the problems you are having now might get transplanted to the new install. The only really clean way to do this is via manual migration. it's pretty tedious but will produce the cleanest system.
You'd have to do an erase and install on the new drive and then migrate what you need by hand from the old drive.

So I have two internal hard drives in my laptop but the hard drive that my music is on is running out of space. I want to transfer my music from the smaller hard drive to the larger hard drive so my computer can run faster. If I do this I'm afraid I'm going to have to locate every song within the iTunes library. Is there a way around it so I won't have to go in my files and locate every song? Any help would be greatly appreciated!
Instead of moving the entire iTunes folder you can copy it, then do the Shift-launch trick to select the .itl file from its new location. If it works, then go back and delete the original location.
But maybe clarify your configuration ... specifically, is your "iTunes Library.itl" file currently on the same drive that your music files are stored on? Or, do you keep your .itl file on a separate drive than the native files? If the .itl file is on a separate drive right now, then moving or copying the music files over to be on the same drive can result in iTunes not knowing where your native files went. You can get around that using the Consolidate utility in iTunes, but that is not necessary if the .itl file lives with the music files.
