Sparse disk would not mount

Hi.
A relative of mine is having trouble with an iphoto library back up.
A sparse disk image was created using tiger (I wasn't there), and a fresh install of tiger was made. The back up is on a brand new Lacie HD and the only files on it, are the disk image and an empty folder called desktop.
Since the back up the person hasn't been able to recovers the images.
I looked into it a bit, but with no success.
I have tried repairs in disk utilities. I can mount the disk (HD), repair it, verify it , but I can't do any of these with the spare disk image.
I also tried some old disk warrior application I have on my comp. but with little success. None of the applications I have tried, have made any changes to the problem.
I tried to copy the sparse disk image on the desktop of the imac, but the copy process stop after a bit :
(The finder cannot complete the operation because some data in "Macintosh HD.sparseimage" could not be read or written.(code error-36))
When I try to verify it, disk utilities start nicely until it get into a frenzy of sounds and multitudes of error lines, and the only way to stop the concert is to use force quit.
I have read few writing about sparse images disk been corrupted, but the person isn't using file vault, and probably didn't use it when doing the backup on previous install of tiger,although i didn't see the previous install .
Please help as there is over 4000 images to recover.
Thx

(The finder cannot complete the operation because
some data in "Macintosh HD.sparseimage" could not be
read or written.(code error-36))
Error code -36 is an Input/Output error. Even Apple calls those errors "Bummers". There is most likely something physically wrong with the new LaCie drive that is causing this.
The chances of recovering the data are pretty small. You can try to duplicate the sparseimage on the LaCie drive. If you can do that, you stand a chance of getting the data back. You could also try a program such as Data Rescue II. Part of the problem is that the files are located inside a disk image. It may be an all or nothing proposition.
I have read few writing about sparse images disk been
corrupted, but the person isn't using file vault, and
probably didn't use it when doing the backup on
previous install of tiger,although i didn't see the
previous install .
For whatever it's worth, the person making the backup almost assuredly did nothing wrong. The only thing they forgot to do is to make sure the backup would be usable by mounting the sparseimage. There is no way that the person making the backup would have known that part of the drive they were storing it on was physically damaged.
Please help as there is over 4000 images to recover.
I wish I could give you better news. Perhaps someone else will have another idea to try. If all else fails, there are commercial vendors that can probably get all the data back for you, but it will be expensive.

Hard Drive and Disk Image not mounting

Hey everyone,
I'm running a G5 Dual 2Ghz. with OSX 10.5.8 I'm having problems with a back up hard drive. It is an external Western Digital My Book 1.5TB SATA drive. After using it for a few months, it suddenly did not mount anymore.
*1) It also would not appear in Disk Utility.*
a) Disk Warrior couldn't find the drive (I think because it's formatted with FAT32)
*2) I then took the drive out of the enclosure and put it in the spare bay in the G5.*
a) It didn't mount
b) It did show up in Disk Utility
c) In Disk Utility it wouldn't give me the option to Repair Disk Permissions or Repair Disk
d) In Disk Utility is says under Partition Scheme: Unformatted
e) In Disk Utility I don't have the option to mount/eject only gives me the "info" option
f) Tech Tool did find the drive and it passed all tests
g) Disk Warrior still did not find the drive
h) TestDisk finds the drive, but does not find any partitions
*3) I then created a disk image of the drive in Disk Utility onto an external hard drive. The image comes back at 320GB, which seems to be about right I think.*
a) The disk image would not mount with Disk Image Mounter. It would say there is an Unrecognized File System
b) In Disk Utility - I don't have the option to Repair Disk Permissions
c) In Disk Utility - When trying to Repair Disk - I get the error: Repairing Disk failed with error Unrecognized FileSystem
d) In Disk Utility - If I click Open - The Log file says:
+Attach Image+
Initializing...
Verifying...
Finishing...
+Image of "disk0.dmg" attached successfully+
+Mount of "disk0.dmg" succeeded+
-But it is no where to be found
e) Disk Warrior can not find the Disk Image
f) I took the new external drive with the Disk Image to 3 other mac computers but the image would not mount
*4. Other things I've tried when opening the Disk Image for the new external drive.*
a) in Terminal - hdiutil attach -nomount "volumes/untitled/disk0.dmg"
b) in Terminal - sudo hdiutil attach -nomount "volumes/untitled/disk0.dmg"
c) Deleting files System/Library/Extensions.kextcache
System/Library/Caches/com.apple.kernalcaches
ALL UNSUCCESSFUL
I'm running very low on ideas. I know I could just erase the drive and reformat it, but the files on it are very important and must be recovered.
Any help or suggestions would be very helpful. I will not have time until after the weekend to try more things. Thanks in advance if you do not hear back from me until after this weekend.

Yes, it will. But if DU says the disk is unformatted then it is also not accessible. If you have files you don't wish to lose then you will need to try recovery software:
Basics of File Recovery
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.

Disk image not mounted

I have had a host of problems since i installed a Time Capsule. The latest is that after reinstalling my system software -- another story -- I have not been able to make back-ups. The message I get is back up failed, disk image not mounted. What is this? On my time capsule there is a disk image of my hard drive on a dog eared page called a sparse bundle. I'm sure this is easy, but I'm stumped.

huk730,
Welcome to the Apple discussion!
Consider the following causes of that error message. Also bear in mind that when you reinstall the system software, Time Machine cannot continue using the same backups as before and will start a fresh set of backups. [http://support.apple.com/kb/TS1338]
*_"The Backup Disk Image Could Not Be Mounted" (Console - “Failed to mount disk image”)_*
First, it is important to distinguish this error message from another, similar Time Machine error that states “The backup volume could not be mounted”. This is important as the causes and cures for these two errors can be very different.
Consider each topic below separately. When one option does not resolve your issue, then move on the next one.
*Unmount the Backup Disk Image* (TC)
If, for some reason, you have manually mounted the Time Machine backup disk image (sparsebundle), or Time Machine failed to eject it after the previous backup, subsequent backups may fail. (Console - “Failed to mount disk image”… “Backup failed with error: 21”)
Eject the backup disk image (white drive icon) by either clicking the little Eject icon to the right of the disk image in the Finders’ Sidebar, or Ctrl-Click the drive icon on the desktop and select “Eject” from the contextual menu. Now try backing up again or launching Time Machine to view previous backups.
*“Disconnect All Users…”:*
If your Time Machine backup drive (“Backup of Users Computer”) is mounted on your desktop or in the Sidebar of the Finder window. then Time Machine may think the drive is already in use. Alternatively, if the Time Capsule hard disk has been recently accessed by a Windows machine, it may not have fully relinquished control. Do the following:
Open Airport Utility and select the Time Capsule on the left.
Click “Manual Setup”.
Select “Disks” at top of window.
Click “Disconnect All Users…” at bottom of window.
Close the Airport Utility.
Now try Backing up again.
“I got it resolved. Apparently it had to do with one of the files being open on the disk from the drive. I had browsed the disk with one of my windows boxes here and it must have left one of the folders "open". Anyway, I rebooted the TC and we are good to go now.”
*Proper Computer Name* #
Make sure your computer has a proper name. Go to System Preferences --> Sharing. Time Machine needs to differentiate your computer from others on your network (i.e. "Bills MacBook" or "Office iMac"). If the "Computer Name" field is blank, create a name. Realize that if this step is necessary, you will likely have to start the Time Machine backup process over again and do another full initial backup.
According to this article, [http://support.apple.com/kb/TS1760], Time Machine may experience problems if your computer name includes certain characters. Make sure the computer name only includes ASCII characters from the following set.
(0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ)
Once a change in the computer name occurs, you should stop and restart Sharing on the affected computer. Uncheck and then recheck Sharing in the Services list on the left.
Let us know if any of the above was helpful.
Cheers!

USB Flash Disk does not mount after Leopard Upgrade

I am not able to use my USB flash disk after the upgrade to Leopard. The disk does not mount at all, though i can see it listed in the System Profiler.
Before the upgrade to Leopard, the same disk used to work perfectly.
Can anyone please tell me how I can solve this issue ?
Thanks.

Check to see if your USB Drive has the latest firmware. Leopard tends not to support older firmware.

Imac have black screen. Start Computer sound come on, no picture. The last time I used the computer I put it to sleep, it never came back. i tried everything that was suggested including puting in the start up disk. The disk would not eject. Some one suggested how to remove it and that did work. Computer going to Apple hospital Tues. July 3, thank you for all the suggestions.

There is nothing wrong with the OS update.
Delete ALL your email accounts.
Restart Playbook
Put the accounts back and ensure they are all set with PUSH ON. Manual (push off) will burn battery.
Similarly delete your wifi connections and add back when required.
Turn off wifi is not connected to wifi.
Any "hunting for connection" in email or wifi will burn up battery.

Disk images not mounting

Here's the question: how come .dmg files downloaded from apple.com (amongst other places) won't mount?
Here's the detail: This has to be a FAQ going by Google searches. I've downloaded the Mac Firefox DMG 3 times, and the Safari DMG from apple.com once, and when I try to mount the images I get a range of different cryptic errors, including "codec overrun", "not recognized", "error -some number or other", and so on. Sometimes, I get two different errors for the Safari image.
Existing disk images on my hard drive mount fine. Today my hard disk has been playing up, with files being corrupted, keychain being broken, prefs disappearing, and so on. I boot from the Tiger DVD, run Disk Utility and Repair Disk, tells me no repairs carried out as all hunky dory. Use Disk Utility on the HD to check permissions, those are fine. Run Onyx maintenance, all is fine. I've not changed the router prefs at all, so it's not that corrupting the downloads.
All was fine until mid-afternoon today, when a number of apps (Firefox, Safari, Dreamweaver) started behaving strangely and the machine kept on hanging. On restart a number of taskbar icons became question marks, so something's being corrupted. Some downloaded PDFs became corrupted.
What I might try to do is download DMGs from my work PC, put them on a stick, and try to mount them. If the problem recurs then that would eliminate download errors.
My conclusion is that either the OS has become damaged, or the HD is physically fubar'd, or at least has some physical errors on it somewhere which DU isn't picking up. If the latter I'm screwed as I'm out of warranty and I might as well chuck the machine in the bin, so let's hope it's the OS. I could reinstall the OS (again) but a) that would be highly time-consuming as I'd also have to reinstall a shedload of apps, prefs, configs, etc, and b) if there's a physical HD error it'll do zero.
I've already spent some fruitless and frustrating hours today on diagnosis, and having done tech supp in my career I know what to look for, so this is my last throw of the dice to try to get some kind person to suggest a) a diagnosis, and b) suggestions for a cure.
Without a cure I might as well take a clawhammer to the thing and get a Linux laptop. Ok, PCs are far inferior to Macs with crappy hardware, but at least you don't lose over a thousand quid when your PC laptop fails.

I was able to get a partial fix of this problem by following instructions that I found on the All Experts web site:
Regarding disk images and mounting media:
delete the following files and folders:
* /System/Library/Extensions.kextcache (file)
* /System/Library/Extensions.mkext (file)
* /System/Library/Caches/com.apple.kernelcaches (folder)
(Note that after deleting these files you need to reboot your Mac for the fix to take effect.)
All of these files and folders were date 18 Aug 2009, which is in around the timeframe when I installed the last security update for OS10.4 ppc.
I say the solution is a partial fix, because it did allow me to open some, but not all .dmg files (the problematic ones are showing a checksum error). Now I find that iTunes will not operate (yeah I know that should be another thread), but I have not used it in several weeks, prior to the last OS update.

External Lacie hard Drive would not Mount on my imac

HI all,
I have had this Hard Drive for a few years now, worked great, no issues at all. Even after upgrading to 10.8 it continued to work.
A few days ago my cleaning lady moved the computer and disconected the Lacie drive (connected via Firewire) and since then I am not able to mount it again.
I see it on my Disk Utility but when I press "mount" I get an error messege "the disc can not be mounted, try First aid" but non of the buttons on First Aid work.
So far I tried re-settign the SMC, of course shutting down and starting back up numerus times but nothing.
I even tried working through Terminal, it can see the drive and its partition and when I looked online I saw a few commends to try and mount it, but nothing worked so far.
Here is what i wrote and got in terminal:

Details on my system:
its 10.8.2, iMac Intel core duo 2
The Drive is connected by Firewire
The drive is clearly there, it's working, I hear and feel it working (spining) but can't mount it.
What can I do in order to mount it and get my data of of it?
this is extermely important as my itunes library is there. PLEASE HELP SOON!
Thanks!

Update:
so, I shelled out the $100 to get Disk Warrior, and got the following messege:
Directory cannot be rebuilt, the file system is unspported
This disk is not a macintosh Disk
and further down the list it said: File system: Windows/PC
All of this is of course distressing as this has been a Mac disk for several years now, not to mention the $100 gone in the wind.
what should I do now?
I have Parallels, would that help? is there a way of mounting the disk on there?
Should I try connecting it to a PC?
Please Help me!!

Applications will not launch and install disk will not mount

Just recently my applications have taken a turn to not wanting to launch. These include anything from Dashboard to the Microsoft Office Suite. It also includes anything that is downloaded form the internet, like the World of Warcraft download client. Long story short, the errors that I constantly get are
System/Library/Frameworks/ApplicationServices.Framework/versions/A/Frameworks/Co reGraphics.Framework/versions/A/CoreGraphics
I figured that with it being a system library issue and the Repair Disk Permissions has been completely useless, that a complete restore would be in order. And I was wrong. For some reason my Genuine 13-inch MacBook Pro Mac OS X Install DVD will not mount. Meaning I out the DVD in said drive and it will attempt to mount but will eventually give up and eject itself. I can load any other cd/DVD into my drive and it will mount without a problem.
Everything is up to date software wise.

Backup disk and Disk Images not mounting

*Intial Disk Utility problem:* Recently my trusty 6 year old PowerBook G4 died from hard-drive failure, with most of my data backed up on external drives. Before migrating data over to my new iMac, I performed "First Aid" in "Disk Utility" on the external backup drive. One of the drives (500GB iomega drive) that backed up my PowerBook and my PC had 5 partitions (4 were FAT32, and 1 was NTFS), somehow got erased in Disk Utility. Even though I was just verifying one of the partitions the whole drive was cleared and renamed: disk2s4 (28kb) and disk2s10 (372.5GB). This didn't take much time, so I knew all the data hadn't been cleared, and checked the Security Options for Erase, and its set to "Don't Erase Data."
*Disk Warrior attempt:* At this point, having a sorta wrecked backup drive that still apparently had data, I bought Disk Warrior and gave that a try. It read the drive the first time, but couldn't recover any of the directory information. Hoping to not overwrite anything, at that point, I didn't proceed with the "rebuild" option. Now when I try Disk Warrior, it just says:
Directory Cannot be rebuilt due to disk hardware failure (-50,447)
- This disk appears to be a MacOS standard sik
- This disk does not appear on the desktop
- This disk is 372.49 GB in size
- Disk ID: disk2s10
- File system: HFS (standard) +even though most of the drives had been fat32+
Now Disk Warrior doesn't even give the option to scan the drive.
*Disk Imaging attempt:* Disk Warrior is claiming a hardware problem (which isn't really the case), so I tried making a disk image in Disk Utility of both disk2s10 and disk2s4. I tried opening disk2s10.dmg in Finder and in Disk Utility, and get the message: "No mountable file systems." In the past when confronted with unmountable disk images, I've used VLC media player. So, I pull up VLC read disk2s10.dmg and music starts playing!!! At first I freak out, then I realize that its the first song listed in my iTunes library -- the data is there, can be retrieved, but I'm not sure how to get it!
*Next attempts:* the only other thing I can think of is to try daemon tools or something on my PC, or bring the drives into the the school IT guys.
Please let me know what you think would work that I haven't already tried. Though I have redundancy in the backups, I haven't been able to recover some data for my PhD thesis due in a month, and therefore haven't given up on reviving this disk yet.

I've downloaded the DataRescue and FileSalvage trials, and am currently scanning with DataRescue which will take another few hours. Thanks for those recommendations, its so useful to have a trial scan before buying.
*General Question:* I noticed through these various attempts that reformatting extra drives in the current version of Disk Utility has become a little more dangerous than before. For example, I was reformatting a spare disk from FAT32 to HFS+ and the drive became unmountable. This never happened to me in earlier versions of OSX, and now it seems to happen every time, and partly why my partitions got all screwy. Any thoughts?

External disks will not mount on new OS install

Hi,
I just had to reformat and reinstall all the OS and applications on a imac g5 for a friend of mine. I have updated all the os to 10.5.8 and have installed user software iWork, iLife, Microsoft office and Roxio's Toast 10 and a family history software called Reunion. That is all that has been done to this new install.
I went to transfer her personal files back and I can't get any external disks to mount. They will all show in disk utility but will not mount the desktop. I have tried 2 different drives formatted in Mac OS Exteded Journalled as well as MS-Dos Fat32. I have also tried flash drives formatted in each of these formats. All of these drives are readable on several other computers I have here, including a 2008 Macbook Pro running Lion, 2010 iMac running Snow Leopard as so on.
When inserted in the iMac G5 I can see all the drives in disk utiltiy and was able to even erase and reformat a drive to differnt format ( mac extended to Fat32) without issues to mount on the other computers.
Cd's mount just fine.
Anyone have any clues as to what's going on? Any thoughts are most welcome.
Thanks

What exactly shows in System Profiler>Hardware>USB for those drives?
Boot from the Install Disc & see if they show up, not grayed out in Disk Utility.
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
We were thinking along the same lines. While at home I dug up a firewire enclosure and put a bootable GUID formatted drive in it (that I had in one of the usb enclosures) and started her computer holding down the option key and then chose to boot from the external firewire. All usb drives are now mounting upon connection. I asume that her drive has bad sectors on it (even though the SMART status says it's OK) and is not loading all the drivers properly for USB to mount. I was suspicious from the beginning that the OS was corrupt when she first had me look at it. It was at that point that I booted it in target mode, connected to my Macbook Pro, and then CCC'd to a usb drive that I had. I then had a couple of difficulties installing the new OS. Should have known......
I am now going to put a new drive in it for her and she'll be up and running.
Thanks so much for your help and thoughts that got me thinking as well.

IMac Disks will not mount under OS 9...

...only through Tiger.
I have an iMac G3 500mhz. It has a partitioned drive, and is running OS 9.x and Tiger. If I insert a CD, it won't mount on the desktop in OS 9. Also, firewire & USB drives won't mount in OS 9.
When I'm in Tiger, these items mount without issue.
What is the problem? Anyone else experience this?
Thanks,
Chris H.

Not sure about the CD, because a CD can have various formats. Some are not readable under Mac OS 9. What CDs have this problem, or is it all CDs? If it's all CDs, the CD driver (in Extensions folder) may be disabled. You can check using Extensions Manager.
For the hard drives, they should be formatted as HFS+ (also called Mac OS Extended). Not only that, but if they were formatted using a Mac OS X, that checkbox in Disk Utility for +Install Mac OS 9 Disk Drivers+ needs to be checked. If should be by default, but if it was unchecked during formatting or partitioning, then Mac OS 9 will not be able to access those drives. And again, there may be some USB and FireWire extensions disabled, which would prevent any USB or FireWire drive from mounting.
The disabling of those drivers is likely if the Mac OS 9 System Folder was being used for Classic under Mac OS X. Mac OS X handles such driver functions, so an experienced Mac user would have disabled certain unnecessary extensions in the Mac OS 9 System Folder. But if that same System Folder is used to boot the Mac directly, those driver functions would be missing.

VST Zip disks do not mount in OS10

I have just upgraded my Powerbook G3 firewire to OS 10.2.8. I have a VST Zip 100 expansion bay drive for my zip disks, but I am having to boot into Classic 9.2.2 for the zip disks to mount to the desktop. Is there a driver available so they will mount in OS 10?
DawnMerr

DawnMerr,
From what I have read, OSX has native support for the VST Zip100...no additional drivers needed. I would try this first: Shut down your powerbook, insert the VST drive if not installed, power up and try the drive; a few users have reported it is not hot-swappable.
However, it should work as it does in 9.x, and some have found success by performing a flush of the caches. Download the freeware utility 'Yasu' here:
http://www.macupdate.com/info.php/id/13416
Go halfway down the page and find the link for Version 1.0.3 for 10.2 and later. Once you have launched Yasu, select the boxes to run OSX's built-in daily, weekly, and monthly CRON (maintenance) scripts and also those for the System, User, and Font caches. If you have not done recently, you can also check the box to Repair Disk Permissions. Running all of the above will take a little time and the first restart will be slower than usual. Uncheck any other box. If the computer does not restart automatically when done, be sure to do so...this is most important.

HD requires repair, but OSX disk will not mount

When I run Verify Disk on Disk Utility my PowerMac 2.7 Dual (bluetooth keyboard, mouse) gives a message reporting "Failure on Exit" and as follows:
Verifying volume “Macintosh HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Volume Bit Map needs minor repair

The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit

My OSX installation disk is in good condition, and I have tried restarting with it in the cd/dvd drive, using the Opt key, but it pops out and the screen shows what I think is a reload sign, a right pointing arrow, and the HD.
Clicking or double clicking any of these produces no result.
If I now reinsert the OSX disk it and the Hardware Check symbols are sen too, but nothing is active.
If I start in a normal way, I get the chime, and the machine is ok, with the usual faults: the optical bluetooth mouse freezes frequently (it is old), the cd/dvd cradle pops out on startup (usualy), and the owner is worried sick.
I used to run EyeTv 1.8.6 using a Terratec(2) gizmo, but stopped a week ago, just too many problems.
I have spent most of today trying to find a solution.
A while back Apple (no warranty left) kindly wiped the HD and reinstalled a totally up to date Op Sys and iLife. But I still ended up having to reinstall OSX again from my disk and archice the "old" system and I am getting so I have had enough.
I have copied my pics and docs to disks (not using "Backup" again - I have oodles of disks I cannot access the info on, which I assume is encrypted by Apple's "Backup" prog, which I am not paying for AGAIN when they owe me 3 years worth of .Mac anyway (Pls do not ask.)
Please help.

Hi-
Welcome to Discussions!
To boot from your install disc, you can do 2 things:
1- Startup the computer while holding the "C" key. This will make the computer startup from the install disc.
2- Using the Startup Manager (startup holding the "Option" key), will bring you to the available startup volumes. Click once on the OS X install disc icon, and then click the "straight" arrow. The computer should then boot to the install disc.
The error that you are receiving may not be repairable with Disk Utility.

I would try running Disk Utility at least 3 times. If all 3 times fail, then you will need Disk Warrior to repair the drive:

Disk Warrior is very good at fixing bad directories, and should give good results if Disk Utility fails.

INSTALLING PSE6 ON NEW IMAC (PURCHASED DISK) WOULD NOT LOAD

I have a new mac computer, OS 10, and loaded the trial version of photoshop elements 6 and then purchased the program. I tried to install using the disk, and got error message, called help desk, they got it loaded after 2 + hours. Now when I click to open the program, it takes 10 to 15 minutes if it even opens.....any ideas??

Thank you for your help! In reading another site, I got a recommendation to run a cs3clean program (http://www.adobe.com/support/contact/cs3clean.html). That worked, although I lost my In Design program, adobe flash, adope shockwave and adobe reader. There are several warnings that this would happen.
I reinstalled all programs (including the new retail pse6), and everything seems to work now. Will not be trying any more trials.

500 GB Hard Disk will not mount on iMacs (after working fine for months)

setup : 2x iMac 24" 10.5.6..wired to airport Xtreme, Iomega 500 GB HD connected via USB
this drive worked fine and has all the pics on it and was used to backup both iMac's via Time Machine.
Today the Airport Xtreme (AX) gives us a flashing orange light and informs us that the 500 GB Iomega disk needs to be connected to the mac and needs to be repaired.
so...we did, with a "disk appears to be OK " message after 'repair'
mounting from within Disk Utility gives us : "The disk “500HD” could not be mounted.
Try running First Aid on the disk and then retry mounting."
(we did just that...!)
We also tried "Drive Genius" with the same results.
whether we hook the drive to the AX or directly to the iMac...no mounting.
The drive (and it's partition) does appear perfectly in both 'Disk Utility' and in 'Drive Genius'
(The iMac does mount other USB items like mem-sticks, camera's just fine.)

While it doesn't sound like this is really the problem since OTHER devices work on the USB ports, never the less, it is an easy thing to try out anyway.
First thing to do is reset the USB chip set on the mother board. Unfortunately, when you power down the computer there is always a bit of power still applied to the motherboard to keep things alive and this usually includes powering the ports to do stuff like detect when a device is plugged in or wants to wake up the computer. The downside of this is when a bus/port chipset goes into a weird state, locks up, etc., simply power cycling (shutdown & restart) the computer won't work.
So first thing to try is resetting the chipset and to do this you have to power down the computer and completely unplug the computer from the wall power (unplug the power cord to your Mac). Also unplug everything from the Mac's ports (USB, FW, Ethernet, etc.) to make sure no parasitic power is still there to keep the chipset alive. Now let it sit for a minute (give those big power caps in there time to discharge). Now reattach the keyboard & mouse only, plug the power cord back in, & start up the Mac. Now see if your USB ports work any better.
Best of luck!
