Can't mount second internal drive

After two weeks off, my Mac can't spin up the second drive, which I installed two years ago and which has been no problem until now. I've done a clean system install and tried all kinds of boots with extensions off, etc. Drive Setup, TechTool Pro, and Disk First Aid do not see the drive. Retrospect sees it: "Bus 1, SCSI ID 2, IBM DDYS-T36958M, version S96H--no driver." SCSIProbe sees same thing, doesn't mount it: "Trying Device 1.2.0--FAILED: SCSI Error: -7932 (2): Sense 4(0). Trying Device 1.2.1--FAILED: Logical Units not supported." Norton Disk Doctor shows location after "Add Custom Disks" command, no volume name (the drive has--or had--three partitions.
Disk First Aid (v. 8.6.1) and Disk Doctor (1.0.5) both say everything is copacetic on the startup disk. TechTool (3.0.4) says all's fine except the system is missing a file called Enabler.
The drive came with an adapter which went between the SCSI cable and the drive. Directions say don't use jumpers with this adapter, which has worked fine up until now. The vendor appears to be out of business--phones disconnected, etc.
Any suggestions appreciated. Thanks, Fletcher

When drives won't come ready, they may be dead, or there may be termination problems. No termination often causes a Mac to hang during startup. Too much termination can cause drive not ready, or data errors, or occasionally work fine.
The usual method of providing termination with a 68-pin controller and 68-pin cable is with a large discrete terminator at the end of the cable. If your SCSI card is original, that is how I would expect it to be set up. In mine, the terminator was stuck to the top of the last drive with double-stick tape.
Recent 80-pin drives often do not have any way of providing termination. They take their address from the jumpers on the 68-to-80 adapter. Some older (generally SE-only) drives can still provide SE termination, and having a drive set for termination while using the end-of-cable termination can sometimes cause problems.

Can I install windows 7 on a second internal drive on a macbook pro 2011?

Can I install windows 7 on a second internal drive on a macbook pro 2011? I have 2 500 gb. SSD drives in my 2011 MacBook Pro. My plan was to install windows 7 on the 2nd drive. I'm new at owning Macs so I have had Windows on main drive using bootcamp but I wanted to speed up my 17" Mac so I maxed out the memory and added the SSD drives. Thinking I could put the 2 operating systems on seperate drives I bought to 2 SSD's. Is there any way to do this. So far I have drawn a blank. Any ideas?

Yes. Just install Windows onto it without using the Boot Camp Assistant to partition it.

How can I make the second internal drive bootable drive bootable for trouble shooting?

I suspect that a newly installed SSD boot drive may be causing instability in my new 2012 Mac Mini Server. The logic board and RAM have been replaced and boot drive wiped and partitioned and 10.10.2 reinstalled. I'd like to make the second drive bootable in order to take the SSD boot drive out of the equation.
Could some please describe the correct method for making the second internal drive bootable.
Thanks.

A quick addendum: your Mac will have a default boot drive set, and if not then it will choose the first one it identifies on the disk (usually the first partition on the first disk, followed by subsequent partitions on this disk, and then moving to the second identified disk, etc.). As a result, if you have to hold Option to select your second boot drive, the next time you restart, your Mac will boot back to the first drive. To make the second boot drive the default one, you will need to select it in the Startup Disk system preferences. This will update the hardware to use this as the default boot drive.

Putting OSX on Second Internal Drive Macbook Pro

I am curious and hopefully somoene who has a bit more knowledge on this can help me out,
so I have 2 internal drives on my Macbook pro a SSD in the main bay and a 750 GB HHD in the superdrive bay - so boot camp still dosen't ( to my knowledge) allow a windows partition to be put onto the second internal drive where i have a ton of space..
so,
my thought on this is - would it be possible to have a very small osx partiton on the SSD to do bootcamp and ect so that then windows bootcamp would get most of the space on the SSD which is in the main bay and then partiton or fully install OSX again on the second internal drive and use that for my main drive for apple stuff and use the SSD for boot camp ( Windows 7 )
Would this be a good idea to do? Or would it potentially cause a lot of problems later on?
I haven't read yet about anyone trying this so thought i'd see what the more experienced apple people know / thought.
Thank you for your time!
Vanessa

It doesn't matter what you originally format it, the Boot Camp Assistant will reformat it as FAT32. When you begin to install Windows you'll need to reformat it to make it bootable, and of course, since the drive will be larger than 32gb Windows will insist on formatting it as NTFS.
You can't make a partition on the second drive if you want to go that route. Boot Camp will need to use the entire drive if you don't want to install it to the Boot Partition.
Also, the drive will need to not be part of any RAID you have installed.

Adding a second internal drive: missing cable?

I recently purchased a Quad G5, to which I want to add a second internal drive. However, when I opened up the unit, only the smaller power supply cable was present. The wider controller cable seems no where to be found. I pulled the drive from my Dual G5, so I'm aware where the cable is SUPPOSED to be located. But nada. Has anyone had a similar experience? Did they short me a cable or is the thing hidden somewhere where I can't find it?

I recently installed a second internal HD and found both cables, but you have to look for them. One of the cable/plugs is located below where the HD goes. You probably found it right away. You just need to pull it out a little to plug it into the new HD. It's kind of an awkward angle but it seemed secure. The second cable is probably the one you're having trouble with. The original HD is plugged into the last plug on the cable. Unplug it from the original HD and pull it down and out. You'll find a second plug (in series) on the cable. Plug the original HD into the plug you just discovered and use the original plug for the new HD. Hope this helps!

Clean Install / Cloning to an second internal drive?

My boot drive is full and now seems slower - is it file fragmentation which slows a full drive?
Here's my set up - I've just added a second internal 1TB drive and want to clean install the original boot drive (350gb) which is almost full and seems to have slowed down. - What is the best way to do this?
Can i clone to a second internal drive?
Can i clone drive 1 onto drive 2 then clean install drive 1?
I want to keep a back up of system set up, software preferences etc.. so nothing goes wrong
Can i then use Migration Assistant to get everything back in place on drive 1 (software preferences etc..)
Then drop the folders in from drive 2 into 1 - then erase drive 2 to start fresh
(I'm running OS 10.5.8)
Thanks for any help

Hi
Yes you can use it as a regular drive. Store Data or even install the OS.
RAID 0 = Stripe. As an example 2x1TB drives striped will give you a single volume 2TB in capacity or thereabouts. RAID 0 gives you capacity and performance with no redundancy. If one of the drives fails you lose everything. Data is 'striped' across both drives. One drive does not get 'filled' up first before data is stored on the second drive.
It's important therefore with a RAID Stripe to have a clear and well-thought out backup strategy if you want to protect your data.
RAID 1 = Mirror. As an example 2x1TB mirrored would give you a single volume 1TB or thereabouts in size. RAID 1 gives you redundancy at the cost of capacity and performance. If the primary mirror fails the data is still on the secondary mirror allowing you time to replace the failed mirror. Data would then be 'mirrored/copied' again onto the replacement drive. Depending how much data you have this can take some time. Performance does suffer whilst this happening.
Depending on your hardware and how far you want to take this there is a whole world of RAID waiting for you to explore. If you had a MacPro for example you could use 4x1TB drives and have a RAID 10. A Mirror of a Stripe or - if you like - a Stripe of a Mirror. Either way you end up with a 2TB Volume giving you some measure of performance with redundancy. Beyond what's available built-in you're really looking at hardware RAID solutions. These can offer RAID 5 and RAID 6 with variations thereof. For example RAID 5 with hot spare etc or RAID 3 or even RAID 50 and so on.
The 'general rule' leaving 10% free if anything should be expanded to 15% if you're considering RAID. Performance degrades alarmingly once you get beyond that figure even more than un-RAIDed volumes.

How to use FileVault on second internal drive with user-folder?!

Hi there,
I've a problem that has not solved yet.
My MBP early 2011 with OS X Lion 10.7.5 has instead the SuperDrive two internal harddiskdrives:
The "System"-Drive (128 GB SSD) for nothing else than the MacOSX installation/applications, and the "User"-Drive (500 GB classic HDD) for all my data and my user-folder. (Yes, I moved it via Terminal commands from "System" to "User").
All works fine, but I am only allowed to encrypt the "System"-Drive via FileVault2. The "User"-Drive is not supported by FileVault2.
I tried to encrypt it with the Terminal commands:
diskutil cs convert /Volumes/WD-Blue -passphrase
(Note: "WD-Blue" is the name of the "User"-Drive)
After confirming the new passphrase, it should be encrypting my "User"-Drive. In the HardDiskDrive-Utility is this hdd converted into a "Mac OS Extended (Journaled, encrypted)". So far, so good
But, now the big problem:
After rebooting the MBP, it is not possible to login.
"An error has occured with this user" (or similar)
I have to reboot, hold CMD+R, and deselect in the HDD-Utility the HDD-Protection, and decrypt this drive with the known passphrase.
After this "correction", all works fine, but without the encryption...
So... any ideas, how to protect the second hdd with my user-folder, without losing my data, because I think, when the second one has been deleted and the new format is "Mac OS Extended (Journaled, encrypted)", it won't solve my problem, because my user-folder is not on the "System"-Drive.
Thank you, and sorry for my english
Regards.

Hi there,
I solved my problem by inform myself...
Here is the solution to encrypt the second internal drive, without losing data, if your user-folder is on the second one (and not on SYSTEM). I will type "WD-Blue" in this example. You have to type in your drivename, that you want to encrypt.
Please note, that modifying your system this way is at your own risk!
Add new user in the ucp with admin-permissions
logout your user
login as new user (admin)
be sure, that no file on the second drive is in use
open terminal
type diskutil list to see your drives
type diskutil cs convert /Volumes/WD-Blue -passphrase YOURPASSWORD
Terminal should encrypt your drive. To check the status type diskutil cs list
If the amount of bytes the same, the drive has been encrypted
So, now still use terminal and type (after encryption has been accomplished):
curl https://raw.github.com/jridgewell/Unlock/master/install.sh | bash
Follow the promts and enter your given password for the encrypted drive (i.e. for "WD-Blue")
Exit terminal and reboot
Done
This way works fine. My user-folder is still on WD-Blue (2nd Drive) and the hdd is encrypted without losing my files.
Regards,
Marc.

Can I install second hard drive on PC?

Hi. I just wondered whether I can install a second hard drive on my PC.
The present Sata hard drive has 640 GB capacity.
If there is a spare port for a second hard drive, is there a maximum capcity limit?
And would any make of Sata 3.5" hard drive be suitable? I would be grateful for any advice.
Thanks,

Second internal drive missing after 10.4.11 update

After gathering dust for some time I've decided up update the OS on an old B/W GS so it is compatible with my ISP. I have 2 internal drives and one external firewire. During the install I saw the second internal drive (which was the former boot volume running 10.2.X) in the list of available drive for install. But after the OS update the second internal drive is MIA. I believe it shows up in the System Profiler report (but with the I'm not sure one is not the Firewire). Any ideas?

I checked the connection and settings are they are according to the manufacturer's recommendations. Upon opening the Mac I saw (then remembered) that the second drive was connected via a Sonnet PCI card. I believe the problem is that the firmware for that card needs updated.
To reinforce that opinion, I've discovered that the drive still appears when booting in 9 and 10.2.x. It's very likely a 10.4. thing.

[solved]Mounting an internal drive

I am trying to mount an internal drive located at /dev/sda6. I want it to be read-write but it mounts as read-only.

Please suggest any ideas.

Have you tried mounting it on e.g. /mnt/foo or some other subdirectory?
What filesystem is it - NTFS?

Can I use an internal drive or external only?

It seems you need a very large (1TB) drive dedicated to Time Machine.
As internal storage is always cheaper, would an internal non-boot drive in the additional PCI slot work for Time Machine, specifically will it see an internal drive or only external firewire drives?
And as I've read in other posts it's not recommended to partition the drive?
Any other formatting suggestions?
Thanks!

You have four drive bays in the computer. For best speed for backup you should install the backup drive in one of your four bays if possible. If that isn't possible then you have the option to use an external FireWire drive. You also have two additional internal SATA connectors. However, you only have one extra bay, the one for the second optical drive. You can install a drive in the spare optical drive bay and connect it to the same ribbon as the optical drive unless you have one of the models that uses all SATA drives, even the optical drive.
The general requirements for a TM drive are that it be partitioned using GUID and formatted Mac OS Extended, Journaled. A TM drive should be at least twice the capacity of the drive or drives it will back up. Over time a TM backup drive will fill up at which time it is either replaced or erased.

Moving iTunes Media folder to second internal drive fails

The whole story is:
I never really used the iTunes media folder system. All my music is on extrenal drive and I was only importing it into iTunes manually to keep my own folder system, for example once a week Ive created a folder with a date of creating and there I had all the releases from that week (some in their own folder or separately but all in this one folder named by a dat eof creation). So on my ext. drive I have lots of these folders by date. And the names of folder always correspond with the date added to iTunes as well
My ext. drive is full now. so Ive decided to take a next step and put out the dvd-rom and put another internal drive (1TB) into my macbook pro which will be used for music and movie data only (the system stays on the old one).
What I want to do now is somehow move all these music folder to my new internal drive, so they can be accessed from iTunes without reseting all its features.
Ive read that one solution can be creating the new iTunes Media folder on that new drive and Consolidate all music from iTunes to this location. Problem is I cant even try it, because when go to iTunes Preferences to change the location of Media folder a hit Create after selectin the new location (new internal drive) after fee seconds the progress freezes and Activity Monitor says that iTunes are not responding. Ive tried to leave it for about half an hour and no changes, even tho theres not much to copy/move cause the Media folder has no music in it, only playlists etc.
So question number one is - why its freezing?
Question number two - any other way to trasfer all my collection and keep its organiation as it is without loosing the iTunes list and be able to use it after transfer?
Thanks in advance for your help and tips

Not sure about question 1...
What I think you should do is try to copy the existing iTunes library folder from <User's Music>/iTunes to <1Tb Drive>/iTunes then hold down option as you start iTunes. You should be asked to choose or create a library. Click choose and browse to the library file at <1Tb Drive>/iTunes/iTunes Library.itl (BTW if the the .itl extension is missing you should probably add it match the current format, but it will work either way).
The new copy of the library should work just as before, but check a few random things first, you can always revert to the previous library with option-start-iTunes if it doesn't work.
Under iTunes > Library > Orgainze Library if the option is available tick Reorganize files in the folder <Media Folder>. This will make sure the new version of your library is as portable as possible. Next under preferences > Advanced make sure that the media folder is given as <1Tb Drive>/iTunes/iTunes Media. If needed you can change this value. If you change the folder at this point iTunes should offer to copy your existing media into this new location. That ought to work, thought it will take some time. Alternatively you decline the offer and then selectively consolidate the library in batches, e.g. by selecting the tracks of all Artists beginning with A, and consolidating just those tracks, then repeasting with, B, C etc. followed by other types of media. If iTunes didn't prompt, or the folder was already correct, you can decide whether to try in batches or use iTunes > Library > Organize Library > Consolidate files.

How can I mount a CD Drive in Single User?

Thank you for reading my question.
I need to run single user mode on my iMac because of a disk problem. I would like to be able to mount the cd drive while I am in single user mode. I would also like to be able to mount usb hard drives with confidence, so that I can copy off files from the internal hard drive.
I am in single user mode, which I get to by holding down Command-S on startup. I can look at the disks that are attached to my computer by executing
ls -l /dev/disk*
However this appears to be adding disks. I started with /dev/disk2 and /dev/disk2s1 etc which I understand are partitions on that external drive. Now when I list /dev/disk* I have /dev/disk3 and a couple of partitions on those devs. Is that normal? Have I not unmounted disks properly?
I have been using a directory that already exists as the mount point for my usb drives using
mount -t hfs /dev/disk1 /cores
which worked fine. Alas the disk I mounted on that directory was too small. Now I can't mount a disk on there. Do I need to unmount or fix up that assignment?
If I were to create a directory in /Volumes is that advisable? How do I make the root directory readable is that by using 'mount -uw'?
Thank you. Please if you answer my question, try to be clear on what commands to use and why. Bear in mind that other people will read this, and no one on the web seems able to write suggestions very clearly. Maybe we can be the first! If I have not been clear, please feel free to ask for clarification. i am not a total unix newbie. Rather in the 20 years since I was a sysadmin, my memory has faded.
Pete

I think you need to post this in a different forum. I think the Developer Forums would be the right choice.
In any event from the little Unix I know you can't mount a removable device until it's connected which means you need to put a CD/DVD into the optical drive. At that point if you enter 'df' you should see the device if it is mounted automatically (which I believe it does.)
In single-user mode the entire drive is readable and all files accessible. You are the 'root' user. In order to put the system into write mode you must enter 'mount -uw /'. Note the '/' at the end of the comnmand line. That makes the entire system writeable.
You do not need to create a directory in /Volumes. When the CD/DVD is recognized an entry in /Volumes will appear unless the disc is unformatted.
Now take some of the above with a grain of salt. I'm certainly no Unix expert.

How do I install a snow Leopard on a second internal drive

I just installed a 2nd internal drive on my MacPro (1,1). I have Snow Leopard (SL) already installed and running on my primary boot drive that works well.
I am looking to make the second drive a mavericks boot drive so I can switch back and forth between SL and Mavericks. I understand I must install SL before moving up to mavericks.
Problem is the SL install DVD does not offer me an option to select a drive other than the startup drive (original drive) to install the software.
The 2nd drive is formatted Mac OS Journaled, 1 partition using GUID. I did this using Disk Utility.
Any Ideas on how I can get SL installed so I can move up to Mavericks?
Side note: I have to keep Snow Leopard as an option because some of my software will not run under Mavericks

I tried to install Mavericks with a USB drive. I started up holding the option key using the boot manager, selected the USB drive, the boot manager froze, then booted to my original snow leopard drive. I'm thinking of using my laptop to put my MacPro into Target Disk Mode to see what happens.
