Storage parition won't mount/unreadable

I'm not sure what category to post this to, so here I am.
I'm running a MacBook Pro with bootcamp with the HD paritioned for both Windows XP and Mac OS 10.4.11 and the remaining volume used for storage, scratch space and extra apps. While on the Windows platform I was deleting very large files from my Z:(personal files/applications) drive. While doing this, the system crashed. Upon restart, I got the error message that my Z: drive was unreadable due to a corrupt disk. I've restarted several times on both the Windows XP and OS 10.4.11 platforms: Users(mac)/Z:(windows) drive is unreadable. On the Mac side I tried using disk utility to repair the drive. It shows my Users(personal files/applications) partition grayed out/inaccessible, along with the Macintosh(main/core system) and Untitled(Windows) partition that are accessible. The info on the Users drive at the bottom of the screen says that it's unmounted. When I try to repair or verify the drive I get an error that says a sibling link has been broken and that further action was not possible.
I have had this happen before and until now was self correcting upon restart.
Any ideas on how to recover the link to this partition?
Thanks

Have you ever formatted the RAID?
The first time you plug in the RAID there is no file system on it. You need to format it (initiailize) it to put HFS+ on the system so it can read it (or you can put RAID).
Select Initialize, and Disk Utility should fire up. Select if you want a pair of volumes, or a single (RAID 0) stripe across both.

Cluster storage won't mount on restart

This has been happening for awhile (in 10.5+10.6), but when I restart my computer my "shared" storage drive does not mount automatically. The Cluster storage resides on a local drive (which is mounted), so I'm not sure what steps would be necessary to mount this virtual drive.
Stopping services in the Qmaster System Prefs. pane and restarting mount the drive and make my services available again.
This happens with Quick Clusters and manual Clusters.
Any suggestions?
Thanks

Not clear on your config.
You are restarting a computer, not waking from sleep.
That computer is supposed to mount a share from another computer, in order to support your Qmaster realm.
The share does not get mounted automatically, and you need to do it manually.
You want it to happen automatically instead.
Do I have that right?
I've not dealt in this realm for awhile, but in the past I have solved this by adding an item in my user account's "Login Items" pane. Seem to recall you can drag the icon of a currently mounted share into that list.
Also, since this auto-mounting is really a generic system issue, you might get better help over in one of the general Mac OS X forums.
Cheers,

Seagate 3TB Go Flex won't mount

Its a Thunderbolt adaptor desk drive paritioned into 16 partitions. It mounts fine on my iMac 10.7.5, 3.4 GHz, but when I switch it to my MacBook Pro, 10.8.2, 2.6 GHz, it won't mount. Error message says its unreadable. But it does appear as "connected" in the System Profiler, and appears as one disk icon in Disk Utility, but not the 16 partitions.

Hmm, I followed the suggestion, but it didn't resolve it. I ran Disk Utility reapir off the iMac and there weren't any errors found on the drive. When I switch the GoFlex to the MacBook Pro, it appears in Disk Utility as the main drive, but no mounted partitions yet, same issue. And I can't do any repairs to that drive icon in Disk Utility from the laptop.
Any other ideas?

External Hard Drive Won't Mount- Need to recover files

Hello Everyone,
I am hoping that one of you fine mac experts may be able to assist ~
Problem: External Seagate FreeAgent Desktop USB external hard drive
won't mount on desktop=ie: no access to my important files.. Please Help!
Details:
External seagate freeagent 500 GB Desktop USB HD ( only 2 months old)
(using for document / file backup-not as a startup disc)
on my Mac G3 350 MZ Blue & White Tower /768 ram/ running OSX 10.1.5 & OS9.2~
~
Problem: Started using the external 500 GB HD 2 months ago -with no problems-until this morning. Tried to double click to open it to access files
and got the "beach ball of death" and needed to restart.
My trusty G3 started up fine, however, the external HD was now
not showing up on the desktop as normal. I troubleshooted -by restarting,
trying different a/c plugs/ different USB ports , ran disk utility..called
seagate -not much help . Seagate said to try the HD on another mac-which I did-
a G5 tower- same problem.
~
The External hard drive will show up in disk utility, but is grayed out.
and when click "mount" same two messages keep showing:
message 1: "a disk attempting to mount as unknown has failed verification or has failed to
mount.please use disk utility to check the disk"
~
message 2- when unplugging and repluggin the usb in-and upon
restart:" you have inserted a disk containg no volumes that mac osx
can read to use unreadable volumes,click initialize to continue with the disk inserted ,click continue"
~
( I really need access to these files- and do not want to re-initialize the HD!!)
I ran Disk Utility /first aid "verify & repair , the following info came up:
Repairing disk "main backup 2007 ".
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid key length ( <<<IN RED )
Repair completed. "
~~
Though it said the repair was completed, the "invalid key length" issue
still comes up when re-running disk utility...Hard drive would still not
mount on desktop-even after restarting .
~~~~~
If there is a mac genius out there that can help?- it would be greatly
appreciated. I have tried to call seagate several times in the last several hours-
1st time-they disconnected me after being on hold 10 minutes-2nd call
I was put on hold for 40 minutes ..Finally spoke to someone ( they are not mac users or mac experts!)and he said I would need to send it to Seagate's Data Recovery-... for a fee of course!
~~~
At this point, I am hoping to just get the files and photos off
the hard drive- I heard about Disk Warrior-should I use that and if so
what version?
Thank you very much!

Will zapping the PRAM be of any use in getting the external to mount on the desktop?
Your external Hard drive is already recognized. But it cannot be mounted on the desktop due to its directory damage. You can certainly Zap the PRAM, and it will not hurt anything, but I am skeptical that it will change the situation.
Do you think the Disk Warrior 4.0 cd will even work on my G3 350MHZ running Mac OS 10.1.5?
If you boot from the CD and run it from the CD, absolutely yes. If you attempt to INSTALL it from a download or a CD, probably not.
Have you ever used Disc Warrior and is using it complicated?
I own and use Disk Warrior. You select the drive to be rebuilt, it builds a proposed new directory from the information and file fragments available.
When complete, it will provide a list of problems encountered, tell you what files have been placed in the "Rescued Items" folder, and allow you too look at your drive using the proposed new directory. Your only decision is whether the new directory seems to be an improvement over the old \[in your case, hopelessly corrupted] directory. You then tell it whether to replace the old directory with the proposed new directory, or to abandon its work and leave your Hard Drive unchanged.
Is there a good chance that the ext HD will still have my files on it- or do you think from what I've described that they are gone ?
From what you have described, your files are very likely to still be there. Sometimes in a situation like this, a handful of files cannot be recovered.
My other thought was to take the external HD there and have them try to recover the files.
Make sure you completely understand the costs involved. File recovery using a service like DriveSavers can run into many hundreds of dollars. They are prepared to disassemble your drive in a clean room and replace controller boards and read/write heads to achieve success. Your drive has serious, but not fatal, Directory damage. The Hardware, and most of your files, are likely just fine.

External Hard Drive won't mount - tried Disk Warrior, am backing up as a .dmg...will this work?

Hi Guys,
Hopefully someone can help! Fairly desperate situation here...
I backed up around 700GB of data to an Iomega external hard drive (supplied by the client), using my Macbook Pro...all was fine when I unmounted the drive at the end of the backup.
The client took the drive away and called me to say he mounted the drive in Windows (on a PC), and he was able to work with the files for a time, but now the drive won't mount...
I collected the drive, hooked it up to my Mac Pro, but OSX tells me it can't mount the drive. It shows up in Disk Utility in the sidebar, but not on the desktop...
I tried repairing the disk using Disk Utility and with Disk Warrior, both tell me the disk cannot be repaired...
I am currently making a backup of the drive as a .dmg file, using a program called Disk Drill...it's slow as I expected, but I'm still not sure the .dmg will mount...because surely it's just making a copy of the data exactly, of which some part is not mounting (a mount directory or something???)
Is there any way you guys can think of me somehow taking the data and backing it up onto another disk?
Specialist recovery services seem to think there shouldn't be any problem recovering the data, and of couse, as a costly last resort, that's what I'll have to do, but does anyone know how they may go about doing it? It is something vastly complicated such as a command line thing?
Sorry about the length of this question...just hope someone can help!
Thanks in advance...

You didn't say what format (filesystem type) the disk was.
However, I'd say your analysis is probably correct. Something has corrupted the disk. You can make a disk image copy to the .dmg which will preserve the data, such as it is, but I doubt extremely if it will fix any file system corruption.
Furthermore, if both Disk Utility and Disk Warrior have said the disk is unreadable I'm dubious that anything else will magically repair it and that recovery probably consists of snuffling through the disk block by block.
However if the filesystem is FAT (Windows) there may be other (Windows) utilities that can fix it.
You said you 'backed up the data'. Does that mean you still have the original data on your MBP? Are you trying to recover the client's changes?

Time Machine encryption - after restart, drive won't mount

Hi all.
I enabled Time Machine on my Drobo drive, enabling encryption. All was good, Time Machine started encrypting away.
I restarted my Mac, and now my Drobo won't mount.
In Disk Utility, it looks like this:
I'm unable to verify, repair or mount the disk.
I wasn't prompted for the Time Machine encryption key, I assume that this is stored in my Keychain and unlocked on the fly?
But regardless - I'm unsure of what to do next! I've got quite a bit of data on the drobo, and didn't expect it to render the drive completley useless. I'll be gutted if I lose my files on my Drobo besides the Time Machine backup I had.
Any help, suggestions, advice would be much appreciated.

Not looking good? But I badly need to recover the data on this drive. How can I ever trust Time Machine to backup my files in the future if it corrupts things like this?

Flash Drive Won't Mount Except At Startup

Just bought a little 1Gb USB Flash drive which is USB 1.1 compatible. I want it for transferring files back and forth between my OS 10.4 G5 at home and the old blue and white G3 (OS 9.2.2) I have to use at work.
Trouble is, the G3 won't mount the drive unless it's inserted before startup. Apple System Profiler knows it's there when I put it in one of the USB slots on the back of the computer or in the spare slot on the Macally keyboard, but in neither case does it mount. I've looked at the USB events log in System Profiler and it registers the device being inserted and its call on the USB Mass Storage driver like this:
13436.785: [ 75579098]: Driver - Hub Driver - Device found, calling USBHubAddDevice. Port 3
13437.266: [ 75580125]: Expert - LoadClassDriver: USBCompositeDevice1.5.6 - calling driver initialize routine... 0
13437.267: [ 75580125]: Expert - LoadClassDriver: USBCompositeDevice1.5.6 - driver initialization completed 0
13437.578: [-1744497139]: Expert - LoadInterfaceDriver: USBMassStorageDriver - calling driver initialize routine... 0
13437.580: [-1744497139]: Expert - LoadInterfaceDriver: USBMassStorageDriver - driver initialization completed 0
So there's nothing there that says "fail" there unless that's what the zero at the end of each line means.
If I shut down the computer, insert the drive then start up, it shows up on the desktop no problem. It won't show up again if I trash and remove it though.
However, a graphite G4 in my office, which also runs OS 9.2.2 and seems to have an identical system install, will mount the drive with no problem on any of its USB ports.
Is this a case of the G3's USB ports being underpowered and there's no way round it, or is there a fix out there somewhere?
G3 Blue & White Mac OS 9.2.x

However, a graphite G4 in my office, which also runs OS 9.2.2 and seems to have an identical system install, will mount the drive with no problem on any of its USB ports.
Try this: Copy all of the extensions on the G4 that have USB in their names into the Extensions folder on the G3, replacing the USB extensions that are there; then restart and test again. Some of them may be older or newer versions than the ones on the G3 now, and that can make a difference. Note that in OS 9.x, it isn't always the newer versions of the USB extensions that work better.
Also see this user tip from Apple employee Joerg Weise. In it he lists 6 USB extensions (with version numbers) that can often resolve USB problems in OS 9, even under circumstances different from those described at the beginning of his comments.

TimeCapsule Won't Mount for Backup

My TimeCapsule is running on automatic for backups but for the past several days, I get a message that the disk won't mount. It worked flawlessly for months. I can connect to the capsule through the finder for manual storage and the wireless works very well. Restarted everything including the ADSL modem that links our network to the internet (and TimeCapsule). Ran Airport Utility several times with no luck. Help!

I bought a Time Capsule when they first were released. Have and iMac and Macbook Pro. I never could get it to work, so I returned it. I recently bought another one feeling that the bugs were finally worked out and I should have no problems. I was able to get it to work properly and used it for Time Machine backups. Two weeks after I purchased it and after my alloted time to return was over, it has gone haywire and i cannot for the life of me get it to perform as it did when I first purchased it. I went back to my old hard drive I was using for backup and have had no problems. The computer can see the disk but cannot mount it. I erased my backups and was able to perform an initial backup, but after that, it would not mount the disk. I give up. $500 dollars and what? Now and hour on the phone with support? Give me a break. Apple products should work with Apple products. This is totally unacceptable, but what can I do? There is no answer to my problem that I can find through support or on the discussion forums. I think I have a real "Apple" on my hands.

Smartdisk Firelite Won't Mount

My 40GB Smartdisk Firelite won't mount on my iMac. It did at first but now it will not. I see the Smartdisk in the system profiler.
I am using the ac adaptor in case the USB port cannot supply enough power.
Any suggestions?

Well I called Apple support because I also tried a thumb drive and had the same problem!
Apple had me shut down my computer, wait 1 minute, unplug the USB cable and then restart the computer. After the computer restarts, plug the cable back in and sure enough the drive mounted.
Well, I ejected the drive and unplugged the cable and tried mounting it again and it worked. THEN the next day I tried again and it wouldn't mount so I did the whole shut down process again. Never mounted!
I do not have this problem with printers, scanners, cameras only storage devices.
So, then I tried the USB port on another computer and sharing the drive as a network device and I can see it just fine.
I also tried a new Airport Extreme Basestation and I could connect to the drive but when I opened it and went to add a new folder, everything disappeared. After panicking for a few seconds, I unplugged it and took it to a PC and everything was there, including the new folder I created.
So for now I guess I will just leave it connected to the PC and access via the network.
That is a poor solution though. I should be able to connect directly to the iMacs USB.

2TB Western Digital Drive won't mount in my Mac Pro. Please Help

Hello, everyone. I have a Mac Pro (MacPro1,1) with an internal drive that won't mount. I bought it used last year with 12GB RAM and 1TB hard drive and SuperDrive. I have since upgraded storage with an internal 2TB drive from Seagate (no problem), and a 500GB drive (no problem) from Western Digital, and installed a second optical drive from an old Power Mac G5. I had an additional newer 2TB drive from WD that I bought as an external. I took it out of its case and put it in a carrier and then in Bay 4 of my Mac Pro. It's the only drive I've had problems with, and I don't know why. The drive is immediately rejected by OS X upon startup. The options include "Eject" and "Initialize..." but I've clicked initialize every time. Disk Utility opens and I can see the drive but for whatever reason, it will not mount. There is one partition on it, and I think when I bought it, I formatted it with GUID and Mac OS Extended (Journaled). I haven't used it as a Time Machine drive, but I've backed up some files on it. I've restarted several times, and I'm not sure if I can hear it spinning inside my computer.
Should I pull it out and see if the partition is still on the disk? Wha

When DU launches or launch it yourself, that is the most useless "eject, ignore" and there is no real initialize command anyway anymore.... Click on raw drive WDxxxx and goto Partition tab, change the number of partitions to anything (another silly item) so you can go to the Advanced Options finally
WD MyBook drives are often not standard SATA drives with power and data connectors.
Does it look like one?
It should be GUID but make sure, you can also tell from the status below.
Might even change it to something else, erase, then set it back to GUID.
Apply. And only then does it matter what user partitions you create.
Jump through hoops for no reason.
If you have Windows or a PC, use WD Lifebuard. Great at testing any SATA drive.
Quick format with zeroes. Then Extended Test. Maybe even Full Format with zeroes to insure no bad sectors.
When and where, at what point in time, did you use it and write files to it?
By "carrier" I assume you mean the drive sled to go inside the Mac Pro.
Did you ever use it in an SATA external other than WD? some of their MyBooks are moled into and drive and case cannot be used separated.

Won't mount CF card reader or accept CD in optical drive

I can not longer mount a USB card reader. The reader power light goes on but it won't mount in any USB port. This began happening at the same my optical drive no longer accepts disks. Insert a disk, and it makes some reading noises, then ejects the disk.

I haven't been able to read a CF card for weeks now on either my iMac or MBA - both computers say the cards are unreadable. This is with both my old CF/SD reader and a brand new one. Both computers read SD cards ok and until recently both read CFs without a hitch.
What give here?

Pismo, OSC 10.3.9, VST Media Bay superdrive sees but won't mount 1.4mb flop

This worked a while back, likely earlier version of X, just tried it and it sees but won't mount or format a floppy that works fine in a Mac Mini (10.4.11 with a Teac external floppy drive)
About to travel, would rather take the Pismo with the VST drive in the 2nd bay --anyone recognize this problem?

Ok, using Yasu to flush all the caches, nothing else, and rebooting
-- did work for the VST ZIP module, which works, mounts a ZIP disk ok.
-- did not work for the HS-120 VST floppy module, but it's different.
Before it did not detect a floppy, just showed up on System Profiler as the drive being present.
Now, Disk Utility did detect a floppy as soon as I inserted one (as unreadable, though it's a Mac-formatted HD floppy; OSX (10.3.9) offered to format it). I tried letting it be formatted, it made all the right noises, but nothing changed. "Mount" is not an option. Tried DOS, no difference.
Well, one working VST module out of two isn't half bad in this case; I can stand traveling with an external USB floppy, they're small enough, and it's very handy to be able to use the VST ZIP where hauling around an old ZIP drive would be, in today's terms, just too much. But for a few extra backups, it's good to have.
Thanks! And I'll check back between trips in case anyone has other suggestions over time.

Can't install Snow Leopard on MacBook Pro - DVD won't mount

I am unable to install Snow Leopard on my MacBook Pro as the DVD won't mount. This is an early 2008 vintage MacBook Pro, intel core duo...
I'm using a OS X Snow Leopard install DVD (family licensed). This DVD has been used to install 3 other Macs in my house without a problem (about a year ago), but cannot be used to upgrade my MBP. Actually, this disk mounted on the MBP exactly once - inserted with system up, the disk mounted. Upon running the installed (a year ago), the computer restarted but hung in boot. After getting the disk ejected and the computer restarted, the disk would never mount again. I've defered upgrade for a year but at this point need to upgrade my MBP at least to Snow Leopard and possibly Lion.
The problem doesn't seem to be with the DVD, since it continues to mount fine in other computers, and in fact a borrowed Snow Leopard DVD also will not mount on the MBP.
BUT ... the problem also does not seem to be with the optical drive in my computer, as it can read & mount the install/restore disks that came with the computer as well as other CDs and DVD ROMs. Only the Snow Leopard install DVDs fail to mount.
I've also tried mounting the 10.6 install DVD on my Mac Pro desktop, making it available over the network (ethernet) with DVD/CD sharing. I can mount the remote disk from my MBP that way, but when I launch the installer, the application launches (its own menus are displayed, I can quit from menu, for example) but does nothing -- no windows open, nothing.
I've also tried "Remote Install" (again with the DVD made available with the Remote Install MacOS X application on my desktop), but when I boot the MBP with option held down, the remote disk is not available as a startup disk.
Zapping the PRAM did not help.
Am off to the store to get an optical drive cleaning kit and a blank DVD big enough to burn a new disk image, but would appreciate any further ideas at this point....

Solution that worked: Copy the Install DVD to a USB flash drive and boot from that.

Thunderbolt external SSD won't mount

I'm using the Elgato Thunderbolt SSD as an external hard disk with my 2013 MBP. Since I'm also using a Thunderbolt display, I usually daisy-chain the disk to the display.
Recently I disconnected the Thunderbolt display from my computer without unmounting the external SSD. Since this also disconnected the disk, I got the usual ticking-off ("You should eject a disk before disconnecting it").
However... since then, the external disk won't mount. It doesn't show up on the desktop or in Disk Utility, though it DOES show up ("Thunderbolt SSD") in System Information.
Because the SSD gets warm when it's in use, I think it's still working. I just can't access it.
Can anyone help?

Is the Apple Thunderbolt Display at the END of the daisy-chain? That's where it should be - all other TB devices should be connected first, with the Display at the end of the chain.
As to why you're having a problem getting the TB SSD to work, I'm stumped. It seems as if you've done everything that I would try to do to get everything working... and I'm assuming that you have powered down and unplugged the Display and all other devices for 15 minutes or so?
Just make sure that the Display is at the end of the TB chain - that's really the only advice that I can offer.
