Mac Pro :: Hard Drive Will Not Mount After Optical Drive Upgrade?

Feb 23, 2012

I recently performed an optical drive install. Had to remove the hard drive bays (I use three hard drives - Luckily, 2 run OSX).  I carefully removed all three drive bays and the empty bay. When I inserted the drives into the computer I had changed the position, swapping one OSX drive with a different one and reversing the drive bays. On restart, the computer started on the drive I had not selected for startup and I received an error message stating the other drive could not mount and it gave three options (Initialize - Ignore and Eject).  

I can see the drive in Disk Utility and repair the permissions (it's also located in the System Profile).  

I tried a few things I read in the community using various Terminal commands but was unsuccessful.   

(Let me point out that I recently switched from a PPC G5 to MacPro and swapped the drives from PPC into MacPro and all has been fine until I removed changed their positions in the bays)

Hardware :: Recover Data From Dead Lacie Hard Drive / Unable To Mount Hard Drive

Sep 6, 2009

Today I went to plug in my Lacie 250 GB USB external hard drive into my 13 in. MacBook to get a shirt template for a design I am making. I discovered that the hard drive just would not mount and show on the desktop, and I remembered that this happened a few days before, but all I did was unplug it and plug it back in, and it worked... except that today, that didn't work at all. I tried the other USB port, and the hard drive showed up on the desktop for about a second, and then disappeared. I kept on replugging it back into both USB ports, but nothing happened.

Then I tried to see if it would work on the PC beside me, and it was recognized as an external device; however, a message came up telling me the drive was malfunctioning. I am guessing this is from ejecting it incorrectly (because I am in a hurry to head to my next classes...I use this laptop at school), but I have incorrectly disconnected it before in the past and this problem never happened to me before.

Every single project I have ever created for my design career is on that hard drive, and all I want now is to get my files back. All I need it to do is show up on the desktop for just the right amount of time for me to copy my files onto my computer.

I read online to put it into the freezer for a while and it should mount, but that didn't work. I tried using Disk Warrior, Data Rescue 3, and Tech Tool Deluxe, but the hard drive did not show up on any of those apps.I tried plugging the hard drive into an iMac as well, but it did not show up either.

Hardware :: Won't Work With Optical Drive Or Hard Drive Failure

Mar 12, 2010

We have i-Mac 20" with built in i-sight Power PC, one of last ones I think before the intel. We have had a few problems before with it powering down and going to sleep. Used to hoover dust out and that seemed to fix it.

Now it won't start at all. I have tried all the PRAM and various commands to re set various things but none of these work. We had a wireless keyboard and I have just tried a wired one but I do not think either are connecting as the tab key light does not come on, which it does when I tested the wired on on my lap top.

When it died it crashed with a cd in drive. I have removed this and replaced it with the mac install disk to try and run the disk check but the optical drive is not starting at all either.

All that happens on start up is the sleep light comes on, then after a few moments fan starts to whirl. I can't hear the hard drive - have tried to rock hard drive to get it to spin but nothing.

Just wondering whether worth trying to replace optical drive or is this being controlled by hard drive - hence its not working nor hard drive. is there any way to recover data if it is the hard drive that is dead? anything else I can try and replace to fix it? could I use an external optical drive connected via USB to start?
I have tried to firewire but not joy their either!

Mac Pro :: SSD On Optical Drive Bay Or Hard Disk Drive Bay - Difference In Performance?

Sep 19, 2010

I just bought a new Mac Pro 6-core and an OWC 120Gb SSD drive. My question is putting the SSD on optical drive bay or Hard disk drive bay, is there any difference in performance? My understanding from my old PC is never to share the SATA cable with the optical drive as it will take the transfer speed of the optical drive, because they are running in the same "channel"?Is the 2 SATA cable in the optical drive bay 2 separate distinct ports/channel?

Hardware :: Won't Get Hard Drive Screws And Optical Drive Standoffs

Jul 7, 2006

I am wondering if anyone knows where I can get the screws that go in the side of the hard drive and the standoffs (screws) for the bottom of the optical drive for a Power Mac G5.

The hard drive needs screws so it will slide into and sit in the case properly.
I bought a Pioneer DVD drive to replace the original Sony SuperDrive. Apparently, there are different sized standoffs for Pioneer and Sony drives. With the Sony standoffs on the Pioneer drive, the tray scrapes the case when it ejects.

IMac :: Second Internal Hard Drive In Place Of Optical Drive?

Feb 5, 2010

I did a search but couldn't find any specific info as related to the 20" (late 2006) iMac. Basically, I do a lot of audio work with Logic and DP and I'm interested in replacing my 20" iMac's optical drive with a second internal hard drive. If anyone has any experience or insight regarding this, I would greatly appreciate your input. About 6 months ago, I did a DIY replacement of my iMac's internal hard drive (upgrade to 1 tb), so I'm pretty sure I'd like to DIY an optical drive / hard drive swap - that is, if it's 1) Proven to work stably (thermally and otherwise) 2) Not going to require the iMac's fan to be running faster/louder than normal Looking at my iMac's system profiler, the DVD drive is on an ATA bus (which, as I remember it, is slower than S-ATA). What kind of transfer rates do you think one could realistically expect with a hard drive on this ATA bus? Also, would I have to be careful about new hard drive compatibility, or are S-ATA and S-ATA II backwards compatible with ATA?

MacBook :: Upgrade My Hard Drive From 500GB To 7200rpm Drive?

Aug 17, 2010

I have a MacBook (Mid 2009) and want to upgrade my hard drive to a 500GB (or maybe higher) 7200rpm drive. I have already upgraded the hard drive once, from the standard 160GB to a 320GB 5400rpm, so I already know how to do it.I just need more storage, rather than using external drives. Also, after I upgraded to the 320GB drive, the startup was much slower than when using the stock drive, so that is the reason for having a 7200rpm drive.

IMac :: IMac 24'' - Replace Optical Drive With 2nd Hard Drive For Raid 0?

Feb 18, 2010

I was wondering if anyone had successfully installed and 2nd hard drive in their iMac?I have a 2 year old 2.8 24'' iMac and the performance just isn't cutting the mustard, it's all hard drive related and I already have a decent 1TB drive in there.I was thinking of perhaps swapping the optical drive with a second hard drive for RAID0, but not too sure if there will be space and was wondering if the optical drive is a standard SATA connector, or if there is some way I could run a SATA+power cables externally?

Mac Pro :: SSD In The 2nd Optical Drive - Pics - Hard?

Oct 28, 2009

So how hard would it be to install an SSD in the second optical drive? is it easier then trying to put it in a tray/ at least more beneficial? Does anyone have pictures of how they did either of these things? I am looking to do this cheap/free i know I will probably need to buy an sata and power cable, but is there a safe way to secure the drive for free or very cheap, ie not buying a specific adapter tray or bracket?

OS X :: Hard Drive Wont Mount?

Jul 27, 2010

I have an external hard drive (NTFS) hooked up via firewire to a firewire audio interface, hooked up to my Macbook Pro with OS X 10.6.4. I accidentally turned off my firewire interface before ejecting the hard drive. (I have done this before, it's hard to remember I have my hard drive on sometimes, and nothing bad has happened). When I turned the hard drive back on, the mac says "the disk you inserted was not readable by this computer." I can pick "Initialize..." "Ignore" or "Eject"

If I click Initialize, I can't repair the disk or anything because it is NTFS.I tried booting into Windows 7, and it does not recognize the drive either.

Mac Pro :: 5th Hard Drive In Optical Bay - Get Adapter 5.25 - 3.5"

May 18, 2008

I was able to manuveur a new sata cable under the fan assembly and connect it the mac pro ON Board Sata connector. Im close to installing a new Hitachi 1tb drive in the optical bay, using the molex power connector there, and my new sata dongle connector. Question: Where do I get that adapter for 5.25" to 3.5" for the hard drive to mount in the optical bay? Ive been googling for 1 hour and I found 1. Noiseblocker NB X-Swing $25 -- Hard to find anywhere in USA to buy it. 2. TransItnernational Pro Caddy -- $39 -- and No noise dampening.. just big cage. 3. The metal rails that come with many ex hard drives. 5.25" to 3.5" standard brackets. $9. looks like this causes the most noise problems. Can you guys recommend which one/where to get my last ingredient for the 5th drive install in the mac pro optical bay.

MacBook Pro :: Not Booting Up With Hard Drive In Optical Bay?

Mar 1, 2012

I have a SSD in the main bay and have my stock Toshiba 500GB 5400RPM installed in the optical bay with a hard drive caddy. When I boot up I get stuck at the White Apple scrren with the spinning dotted wheel or it boots up to the desktop and my mouse and keyboard freezes. Has anyone else experienced this problem or have a resolution? I tried two separate hard drive caddys and two separate hard drive thinking these might be the problem with no luck.

MacBook Pro :: Hard Drive Enclosure For Optical Bay?

Apr 8, 2012

I have bought a caddy from ebay some time back to replace the optical drive with ssd.  It worked great. Here is my current configuration: SSD is in optical driveStock hard drive stays same as it was Now I am planning to upgrade SSD and install the drive in the place of stock hard drive instead of in optical drive (to take advantage of higher speed).  But the stock hard drive doesn't fit in to the caddy that i bought.  It worked great for SSD, but not the internal hard drive. 

1) Can someone recommend suitable caddy model, (hopefully cheaper one).  Or if i take out the screws from hard drive, it may fit into the caddy that i have.

2) My admin user is configured in SSD, which should not have any problem after migration.  But my regular user is in stock hard drive.

OS X :: Recover Data From Hard Drive That Won't Mount?

Jun 19, 2009

Long story short I dropped my 500GB Maxtor external HD (which is really just an internal HD in a chase). The drop was about 3 ft. It was not on so I don't think there will be much damage to the disk, but it no longer mounts. I was wondering if anyone could think of a way to get the disk to mount so I can recover files saved to it. I have Tech Tools, and Data Rescue II to recover the drive but as long it is not being recognized by the computer those applications are useless.

OS X :: Unable To Mount Lacie 500 GB Hard Drive?

Jul 26, 2009

I am new to this forum and hoping for some advice with this hard drive issue.

I opened a brand new Lacie 500 GB Hard Drive. It is connected to my macbook via usb. I selected it as my hard drive destination in Time Machine and ran the backup option.

The hard drive did mount. About 5 minutes in the backup option failed - a time machine error: time machine backup failed.

I ejected the drive and unplugged it/turned it off and rebooted my laptop. Now the hard drive does not mount on my desktop however will show in disk utility. It lists with the Lacie name and another subdivision under the name.

When I try disk repair, erase or partition..I always get the same message: resource busy. After the error, the hard drive subdivision disappears leaving only one name on the list in disk utility. (It does not have the name underneath it).

I apologize for my semi technical description. I am new to mac and appreciate any advice on how to fix this issue. All I want to do is backup my laptop using the new hard drive with time machine.

Hardware :: External WD Hard Drive Won't Mount?

Oct 5, 2009

Hello everyone. I've been using an external Western Digital My Studio (500GB) drive for the last year or so with a Core2Duo Macbook Pro, and have had no problems until this morning. The drive is used primarily for Time Machine backups, but I also have some photographs stored as well.

This morning, just after I'd begun copying some of these files to another external drive, the WD drive went down, and now will not mount/showup in Finder. It DOES show up in Disk Utility, though with the Time Machine volume grayed out. I get a "could not mount" error when I click on the "mount" icon, and nothing else I try (rebooting, unplugging drive power supply, etc). has worked. I'm trying to avoid the erase-and-reformat option, because I'd lose some potentially valuable images.

Desktops :: External Hard Drive Unable To Mount

Jan 20, 2010

Without warning my iMac [OS X Snow Leopard] popped up an alert saying that I should eject a drive before disconnecting it. I had done nothing to generate this error message. I clicked ok to close it and noticed my 4 month old, external 8T Mercury Elite-AL Pro Qx2 was no longer visible in my drive directory. I also noticed this external unit was making a looped grinding noise as if it was trying to write without success. I figured one of the drives failed and took it to the mac doctor. Other than a few directory errors, everything appeared to be fine, so I paid the service fee, brought it home and plugged it in only to find the same prob - obviously it's something with my iMac. Before I go spending more service fees, I wondered if anyone here could point me toward a method of discovering what might be wrong. I ran disk utility [verify and permissions] and fixed some directory errors, but don't know how to look further. iMac was home networked with a PC [Windows] and a laptop [Windows]. I did notice something wacky with the PC, but its very old and I expect it to die any day. I was running the network through the PC, so I direct connected the iMac to the router and modem but no change: still cannot see the external drives. What other info do you need to make an educated guess for me?

Hardware :: External Hard Drive Spins Up But Won't Mount?

Feb 25, 2009

I have a LaCie 320 GB external hdd (USB 2.0) that worked perfectly until last night. Now it won't mount when I connect it to my computer, nor can I see it in Disk Utility. Disk Warrior can't see it either. I tried connecting it to my roommate's MBP with no luck.

It spins up just fine and doesn't make any clicking noises or anything like that, so I feel like there might just be some hope yet; I'm thinking it might just be a faulty USB cable or something, but I don't have a spare one to try it with.

OS X :: External Hard Drive Format - Mount On Pc - Copy More That 4 Gig

Apr 3, 2009

Alright, so My ipod is formatted for windows when formatted in this you can only copy chunks of 4 gig things using it as an external. but if you change the formatt of it to take all sizes, then it's not compatible with mac and pc. =/ i had it originally formatted for pc because i just recently got a mac book pro and it's my primary computer. well on to the hard drive trouble that is related i'm borrowing my friends external to get a 8 gig file from my pc to my mac. it's formatted in fat32(windows and mac read) but that format only allows for a 4 gig max to be put on it at one time. so i guess i'm outta luck there, i've looked at JR split but who knows it that will work. My main q is, i'm going to be getting my own personal external soon and i want to know whats the best way to format it that it will mount on my pc and my mac and allow me to copy more that 4 gigs of stuff on it at a time.
