Firewire HD won't mount unless I reboot after being ejected?

Hiya
I'm not a Mac newbie, but I am a FW newb. I've used USB 2.0 external drives, but I finally got a MacBook Pro so I thought I'd give FW 800 a go. I got a drive that's designed to work well with Mac's (Seagate) that does USB 2, FW 400 or FW 800. I'm using FW 800, which works fine, however once I eject the drive it won't mount again if I plug it in again to my Mac or my partner's unless I reboot the machine I'm trying to get it to mount on.
It's quite odd as this wasn't the case with USB 2.0, ie it'd mount over and over without reboots after and eject. Is this how it's meant to be or is something else awry?
Cheers.

I was having trouble with my FW 400 burner in SL.
Check out Ken Marks solution in this thread, it works well:

My Mac won't mount my external HDD after installing Lion - What can I do?

My Mac won't mount my external HDD after installing Lion - What can I do?
HDD: Verbatim 3.5'' External HDD eSATA & USB 2.0 #48802
I can not find it in Disc Utilities - so I can not repair it.
I also haven't found any Driver for the HDD to do an update.
My Mac is running on the most recent updates of OS Lion.
The HDD worked before. It contains my former Time-Mashine Backups. I would like to use this drive again. It isn't very old yet.
It would be much appreciated if anyone could help.
Cheers,
Yves

OK, try restarting in Safe Mode and if that doesn't work try resetting the SMC and PRAM.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

- Restore from backup
- Restore to factory defaults/new iPod.

External firewire drive won't mount

I've got an external Western Digital firewire drive that's been somewhat flaky recently, and today my Mac won't mount it.
When I open Disk Utilities, I can see the drive (along with the other drives daisy chained together). When I click on "mount," I get a message saying the drive can't be mounted and that I should try running disk repair. I've run both repair disk and verify disk a few, and each time it says that everything is just fine. However, the drive still won't mount.
Any thoughts about how to get the drive working again?
For what it's worth, this drive is basically my manual backup drive that I use each day just as a safety backup. I don't think I'm going to lose anything extremely important if this drive is dead or if I have to try erasing the drive, but I'd like to see if I can rescue it first before taking drastic action like that.
Thanks!

Dale,
That sounded like a brilliant thing to try. I took the drive out of the daisy chain and plugged it into the unused firewire port in the computer. I ran the repairs and crossed my fingers, but came up with the same thing
At least I've eliminated one more option. Wish I could mark your reply helpful, but I'm not seeing that option available . . .maybe I've used my "helpfuls" for one day.
Although this is PROBABLY duplicate material on this drive, I'm going to hold out for another day or so in case anybody else comes up with another brilliant idea before I take the plunge and reformat the drive.
Thanks!

60 GB external Firewire Drive Won't Mount

I have a 60GB external Firewire Drive that I have been using for a long time. I just turned on the computer and it won;t mount. I opened up the Disk Utility and I see that on the left side it says "57.3 GB Maxtor." I repaired permissions and verify disk. It still won't mount.
I don't want to have to erase it if possible. There are files I need on that drive. How can I get it to mount so I can grab some files off of it and move it to another drive?
Thanks in advance

Hi Edwurd,
What the message is telling you is that Disk Utility and the "underlying task," the Unix utility fsck, can't repair the volume.
Time for stronger medicine if the data is critical. There are commercial products that work differently and can recover disks when fsck can't. Look at Disk Warrior or Drive Genius. BUT... given that Disk Utility thinks it's a "non HFS volume," I wouldn't be optimistic.
If the external drive's data is unimportant - e.g., a backup you could rewrite - then see if Disk Utility can repartition and erase the drive. If only the catalog or partition map is bad, this will get you a working drive. But if you can't repartition with Disk Utility, suspect a hardware malfunction and check your warranty.
Good luck,
John

FireWire drives won't mount

Neither of my FireWire drives will mount on either my iMac 20" G5 or my iBook G4...I have a 500GB WD MyBook and a La Cie 80G. I've gone through all the suggested tips, and still nothing. I've reset the PRAM several times, reset the firewire bus by turning off the computer and unplugging it and the drives for a while, etc. I've tried different cables, too.
The drive shows up in the system profiler as an unknown device but not in the Finder. I have a USB hub with a card reader and 4G SD card that shows up just fine. I tried the MyBook in the USB port but it didn't show up there either.
The power supplies are working, as the indicator lights are on for both drives.
The MyBook was working fine until recently; not sure when it stopped working. I hadn't used the La Cie for a while but hooked it up to store iMovie files.
I plugged a Canopus ADVC-55 analog-to-digital convert into the FW port on both computers and it showed up as a named device in System Profiler. That tells me the port is OK and the problem is with the HDs--right?
Very frustrating! Hope someone can help.
Thanks in advance.

For what it's worth... I'm having the exact same issue and so are many others on the forums since 10.5.6.

---cross posted---
I'm having a very similar issue as of the last few weeks at least. Periodically I'll turn my FW drive on and it won't mount and isn't visible in Disk Utility. This is usually after waking the computer from sleep.
The only way to get it back is to restart.
Also the console shows a long running list of errors that seem to occur non-stop when the drive is on, connected, but not mounting.
AppleFWOHCI_AsyncTransmit::waitForDMA
AppleFWOHCI_AsyncReceive::waitForDMA
I've also noticed that the system occasionally will not boot up and instead freezes on the Apple logo on startup. Not sure if this is related however.

Media won't mount via external optical after 10.4.4 update

I did a search of the forums and found nothing related to my problem, sorry if this has already been covered. This is my first post on the support forums, so please forgive me if this is posted in the wrong area, and feel free to point me in the right direction if I should be asking this queston elsewhere.
The subject heading says it all. I have an external Firewire DVD writer, and since I updated to 10.4.4 it won't mount any media when connected second in a chain after my external hard drive. If I disconnect the hard drive and plug the optical drive directly to the iBook, discs mount just fine, but when it is second in the chain ... nothing.
Additionally, neither Disk Utility nor Toast will recognise the optical drive in order to burn data unless the device is plugged directly into the computer.
The obvious solution would be to reverse the order of the devices, so the optical drive comes before the hard drive, but I have experienced problems with hard drive access and speeds of transfer to the hard drive when I've hooked things up in that order, so it is not an ideal solution.
Any help would be greatly appreciated and thanks in advance.

Dear Joel,
for me I have a solution. I had to turn spotlight off with "sudo mdutil -i off" and then to delete all the files in the hidden /.Spotlight-V100 folder and then turn spotlight on again. And then wait for the computer to index again BEFORE the restart. Can be observed in the activity monitor: task mdimport.
I found my solution on the following page:

External firewire drive not recognized when re-attached after being ejected

I'm using a Seagate external drive for Time Machine backups. When I need to disconnect the drive from the Macbook's firewire port, I drag the drive icon to the trash/eject icon. When the drive icon disappears from the desktop, I unplug the cable. If I plug the drive in again, the drive responds by lighting up and spinning up, but the icon for the drive never appears on the desktop or in the Finder window. Time Machine doesn't run as scheduled because it doesn't know the drive is attached. If I briefly power down the drive before plugging in its cable, the Mac recognizes the drive and it can be used by Time Machine. Is there a different procedure for unmounting the drive that would eliminate the need to power it off before reconnecting?

Thanks for the reply. The drive is mounted properly when I follow your procedure, same as it was when I powered down the drive. Your procedure differs from what I described in that the drive is powered down before the cable is unplugged. Maybe that's the safest approach. But I was looking for a way to avoid powering down the external drive since that involves unplugging the power connector (i.e., there is no power switch). Any way to avoid the power down?

External Firewire HD won't mount after Connecting to B&W w/ bad Firewire

I've tried and tried to find the answer, so finally I post...
I've had two external Firewire Laptop HD enclosures become unmountable after hooking them up to a 400 Mhz powermac G3. This has been 6 months apart. I used to use the Powermac B&W ... I know the Firewire worked at one time, but cant remember if it was before or after I added a Belkin USB 2.0 PCI card.
After clean installing... 10.3.2 .... no Classic... I hoped it would wake up the Firewire, did not. So hooked up the external HD to the USB.... it worked. Then, went to the eMac and via Firewire hooke up the same external HD.... it worked.... for 2 hours. Disconecceted, reconnected and like the other one...... no more mount. Not in classic, not on any comuter. If I daisy chain it to another Firewire external, the About this Mac no longer recognizes info on either. Once removed, the computer recognized the info the good one. Disk Utilities does not recognize harddrives in the enclosure... I put a different HD inthe enclosure.. still not mounting
It spins and receives power.... but no mount. Is this firmware? The hard drive is not corrupted... I put it into a mac mini and was able to extract the info... but what has caused this B&W's fire wire to go, and caused 2 of my externals to go as well....
Help.

try the following to reset the ports:
1) zap PRAM - reboot holding down Cmd-Opt-P-R and left the machine boot cycle 3-4 times
2) reset Open Firmware
reboot holding down Cmd-Opt-O-F
at the screen type <reset-nvram</i>
press Return
type reset-all
press Return
3) disconnect ALL devices from the computer
unplug the computer from the wall
let it sit for 10-15 minutes
plug back in and reboot

Firewire HD won't mount

We have two macs. We recently restored our MacBook from a hard drive error, and we have a lot of important stuff saved on a My Book external HD. Unfortunately, it doesn't mount on either the MacBook (running OS 10.5.5) or our iBook (running 10.4). It appears in the system profiler but not in either Finder or Disk Utility. Does anyone know what might be the problem, or better yet, the solution?
Thanks in advance!

See the following:
FireWire Issues- Drives disappearing or unmountable - corrupt volumes - solutions;
What to do if your computer won't recognize a FireWire or USB device;
LaCie's Mike Mihalik checked in with some tips about dealing with FireWire failures:
Seems like the FireWire issue needs to be revisited quite often. Here is my often repeated suggestion which appears to clear up many FireWire issues: reset the FireWire ports. Panther has a Finder Preference to show mounted volumes on the Desktop. You must set this for mounted drives to be visible. Please follow these instructions to reset your FireWire port. Here is a summary:
1. shut down and disconnect all external drives and peripherals ; make sure nothing is connected to the FireWire ports.
2. use Apple Disk Utility to repair permissions on your internal boot drive.
3. shut down and disconnect the AC power from the computer as well as the drives; if laptop, also remove battery; let sit unpowered and unconnected for 15 minutes.
4. reconnect AC power to only the computer (battery too if laptop)
restart computer.
5. verify that FireWire ports are visible within Apple System Profiler.
6. reconnect FireWire drive (only one); refresh window within Apple System Profiler to rescan the FireWire bus; confirm that drive is visible.
7. confirm drive is OK by using Apple Disk Utility and apply First Aid
repeat for other drives, one at a time.
And, you can try using Disk Utility to repair the drive:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

WD firewire drive won't mount, help?!

My firewire external HD wouldn't mount, although, using disk utility, I can see the said drive. So, I clicked on 'repair' button, but got the message saying "filesystem verify or repair failed". What should I do next? I could try the recommended method of using restore disk, but I'm not sure if that'll erase all the content from my HD. Should I try other recovery software? What would be the software to use? Any suggestion is appriciated.
Thanks in advance,
DF guy
PS. I tried to hook it up to another Mac with 10.5.7, but also got the same error.

I feel for you, but don’t give up too quickly. Start by trying to make a copy of your most important data onto the new drive. Format that new drive with Mac OS Extended (Journaled) and the GUID Partition Scheme.
As the drive shows in Disk Utility there is a fair chance that it will show as an available source in Carbon Copy Cloner. When you have copied CCC from the downloaded .dmg to your internal volume (say into your Utilities folder), launch CCC, select the menu item ‘Update CCC’, check the ‘beta releases’ box and you will have the latest release, v3.3.1-b3. (Even though it’s a beta is has been out for long enough to have been well tested, and it will maximise your chances of copying where there are disk problems). If that volume does appear in CCC’s Source menu, select it and choose “Incremental backup of selected items”. Select small groups of items to be copied, starting with those that are most important to you. Repeat with other groups of items until you think you have managed to copy as much as you can. (Failures to copy certain items will not adversely affect whatever has already been copied).
Don’t hesitate to get DiskWarrior -- everyone should have it. Once you think you have copied as much as you can with CCC, give DiskWarrior a try. It is agonisingly slow if run from its CD - copy it to your boot volume and run it from there. Run it in its default mode first. If that fails try its "Scavenge" mode.

MacBook Pro won't mount *2nd* DVD until after reboot.

MacBookPro5,1, Intel Core 2 Duo, 2.53 GHz, 4G ram, Mac OS 10.6.8
This MacBook Pro will not mount more than 1 DVD without a reboot in between discs!
These are commercial movie DVD's in excellent condition.
I can mount and watch one commercial DVD with no problems, but when I eject that disc after viewing and insert another commercial disc, it will not mount. I can hear the drive spin up, then spin down, then spin up again, etc... eventually the Finder takes over and says that I've inserted a blank disc and do I want to ininialize?
Eject command does not work while this spin up/spin down loop is occurring. If I Shut Down before the Finder finally recognizes there's a disc in trouble, then reboot and hold the trackpad button, the disc will eject. If I then trash all DVD preferences, the disc will mount and eject on command.
Inserting another disc will result in failure to mount! Etc...
Any ideas?

I should have updated this ages ago. Sorry.
The solution to the problem was to remove the DVD drive, take the cover off it and clean the lens in the reader mechanism. Just Google up the disassembly directions for your particular Mac model.
Downhillracer1's solution, compressed air blown in through the disc slot is certainly easier and might do the trick if all you've got is a spec of dust on the lens, but if it's a problem with some kind of film deposited, opening it up and cleaning the lens is more thorough.
My DVD drive now reads and burns with no problem.

External firewire drive won't mount on macbook but does on ibook

Hello,
I'm trying to hook up my icybox external hard drive to my new macbook but it will not mount. It works fine on my Ibook G4.
Type is IB-351UE hard disk is a Maxtor.
I read about people having problems with USB drives but can't find much about Firewire drives.

Thx. Yes that was what i thought but there is no update as far as i can see.
http://www.raidsonic.de/en/pages/home/home.php
What would be the difference between the ibook and the macbook ie why would the firmware of the drive matter?
