OS X Lion :: External IOMega Drive Won't Mount After 10.7.4 Upgrade
May 17, 2012
After upgrading to 10.7,4 I can no longer access my external IOMega Prestige drive. This drive is encrypted/protected via IOMega's Drive Protection software.
The following is in the kernel log after I enter the password for the drive.
I recently performed an optical drive install. Had to remove the hard drive bays (I use three hard drives - Luckily, 2 run OSX). Â 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). Â
I can see the drive in Disk Utility and repair the permissions (it's also located in the System Profile). Â
I tried a few things I read in the community using various Terminal commands but was unsuccessful. Â Â
(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)Â
Prior to upgrading to Lion I used SuperDuper to create a copy of the existing internal hard drive on an new external drive (iOmega eGo 500GB). Tested booting from the external disk and it appeared to work correctly. Upgraded to Lion. Several days later attempted to boot from the external disk (by setting the start up disk in the system preferences) but it fails. The system always boots into Lion.
What I've tried: Setting the start up disk through system preferences. Holding down the option key to select a disk on startup - interestingly enough I only see the internal hard disk and a recover HD. No sign of my external disk. Using a clean partition on the external hard drive I installed SL from the retail DVD. This produces the same effect of system booting to Lion on the internal drive, which suggests that the problem is not related to the copy I made using SuperDuper, but rather has to do with the external drive or something in Lion that prevents using an external drive (but I've never heard of such a thing).
I've not Time Machine'd in about 3 weeks. After working fine for several months, out of the blue I get this error. I think it was -61? "Get Info" said it was read only. I couldn't figure out how to make it write & read. Now, out of the blue, I can't even mount it.I'm at a loss. My iMac is on it's last legs and I'm playing with fire. I guess the first order of business is to mount the thing but it just does nothing or IDK how to force it to do this?
I have this sans digital USB towerraid enclosure, with one, 1TB drive in it. It's formated as NTFS. It was working just fine, but for some reason, I went to connect it to a windows machine today and it basically froze up the computer. so i tried a few things, and it was still freezing the computer.So i connect it to my macbook pro where it normally is, and when it tries to mount the device i get an error from NTFS-3G. I added an attachment of the error it gives. I tried inserting the command line it suggests in terminal , but it didn't really do anything. I'm not really familiar with terminal or how to use it fully.
Disk first aid sees the drive but the "mount " button is dim. I am connected by a usb cable. I am using Lion 10.7.3.Â
I had been using the drive connected to an airport extreme. That configuration failed its connection to my imac. The drive is now connected now directly to the computer. .

I've got an external 500gb Seagate drive with 2 journalised partitions.....one for my time machine backups and the other for holding audio samples for my drum machines and such. All of a sudden today the audio partition won't mount but the time machine partition still works fine. I go into disk utility and it shows ther but just says unable to mount when I try to mount it. It suggests first aid so I verify and repair numerous times and it says everything is ok. I can boot up Ubuntu in VMware andboth partitions are visible and all the files are there....everything is just as it should be. I was using 10.5.7 and just upgraded to 10.5.8 tonight and nothing changed.
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.
I just purchased a new iMac, System 10.7.4. When I tried plugging in my old WD external with a newly purchased Firewire cable (couldn't attach with the cable that came with the drive originally), the drive didn't show up on my desktop. I tried shutting down and restarting, thinking that would help, but it did not.  I then removed it and placed it back on my G5 Tower and it works fine. I am running system 10.5.8 on my old mac, just as an FYI. I need this drive as my time machine backup is on it.
I disconnected a working external 750 Gig G-Drive. When I reconnected it, it won't mount. I have restarted the computer. I have disconnected & re-connected the drive. Still no luck. What should I do?
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?
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.
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.
After a lifetime of owning PC's I finally purchased a MacBook Pro running OS X. I installed Parallels Desktop 5, Windows XP, and several Windows apps to have dual functionality. Now I need to write to my NTFS ext. hard drive where I backup everything. It has 800gb of space left, so it would be a shame to get a new one just b/c I have a Mac now. I first installed MacFuse and then NTFS-3G. Now when I reboot, the ext. HD won't mount at all. What have I done wrong?
I just installed a new internal hard drive into my macbook as my old one was failing. Before doing this I backed up all of my information through Time Machine onto a Seagate FreeAgent external hard drive. I've been using this external hard drive for the past two years and I've never had any problems with my macbook mounting it. Once I had all of my personal information backed up I took out the external hard drive and then proceeded to take out my old internal hard drive and installed the new one. I installed the Mac operating system and the Macbook started up just fine but when it came time to reload all of my personal setting using Time Machine my macbook didn't recognize that there was an external drive plugged in. I know it isn't the external drive as it mounts just fine on other laptops. how I can get my macbook to mount the drive so that I can transfer all of my information onto this new internal drive?Â

After upgrading to osx 10.9.3, my external hard drive was not able to mount, but it can be mounted without issue in osx 10.6, how do I solve it? it was formatted by disk utility. Â
I'm having a series of problems. First some intermittent audio problems with Garageband, then, then some external drives won't mount, and now I can't sync to my disk from the iMac. I've run Disk Utitilies a few times and when I do Verify Disk Permissions, it finds a list of things to fix, I then hit Repair Disk Permissions and it fixes them, and then hit Verify Disk, and it say the disk appears ok. When I do Verify Disk Permissions again though, it finds another long list of things to fix. Is this serious? What should my next step be? Should I reinstall the entire system?
It's about 2 years old and been working fine. Now it won't mount on my Imac (tried it on 3 computers). It is not seen by disk utility or system profiler. I tried resetting PRAM. I am on OS 10.5.8.
I've been running a Toshiba 1TB external drive on my Mac Pro tower and it's been working fine. But yesterday it wouldn't mount. I could see the drive in Disc Utility, but the partition wouldn't mount. I brought it into work where I'm running an iMac and it mounted just fine. Why would it stop working on one computer (where it was previously fine) yet work okay on another? And how do I get it working on the tower?
After using OS Lion, I used to use this HD as my time machine.Yesterday I wanted to backup, found out that my Mac pro can not mount this HD anymore. Other my older external HDs are working well, except this one.
I wonder why? My console shows fallowing error,p.s: already did SMC and PRAM, still doesn't work.Â

Periodically, my iOmega external HDD unmounts (dismounts?). Only after disconnecting and reconnecting both the power and the USB (connected to a powered hub) does the HDD mount again. This has happened about 3 times in the last 3 months. The HDD is about 2 years old and I have had no other problem with it. It works fine other than the unmounting.
I'm having difficulty with my external hard-drive, here's the info on that one:Â
Disk Utility won't allow me to mount the drive, I've tried using a number of softwares to read it (working under the assumption that it's an NTFS drive), including Tuxera and Paragon. I have too much stored on the hard drive to empty it back onto my old computer, and so I'm not able order to re-format it.
I bought an Iomega Prestige 1TB external harddrive a couple months ago with it running off my Macbook Pro.
I just flew down home for spring break, leaving my Macbook Pro charger at school. However, I do have the harddrive with all my backed up files. The problem is, my PC laptop (Dell, Windows XP) does not recognizes it. When I plug in the harddrive and turn it on, the computer recognizes that there is something plugged in (it gives me the option to safely remove hardware), but there is no sign of the drive anywhere.
I can not get my Macbook Pro running OS X 10.9.4 to recognize a 5 year old external hard drive from iomega. The product code is 31759000 RDHD-U. The hard drive powers up, all cables have been checked to work on other devices, and yet nothing happens when connected.
