10.4.7 Update Now External Hard Drives don't work w/Camcorder on

I just updated to 10.4.7 and now when I have my firewire camcorder (Panasonic PVD-252) connected, my two external firewire hard drives (both Lacie) do not work and it causes the Finder to freeze. When I turn the camcorder off, the problem stops.
I had heard of this issue with certain camcorders with older versions of OS X but it was fine before the update (in fact earlier this evening).

Yes to all. I even tried to connect it to my old iMac G4 (that I also upgraded to 10.4.7 at the same time) and it didn't recognize the camcorder either. I will have to borrow a friend's different model camcorder and see if it is recognized.
I also had a disk error that Disk Utility had to fix on both the G5 and G4 iMac that appeared after upgrading to 10.4.7. And for some reason the G5 would not boot from the CD/DVD where the G4 would. I tried and tried and the G5 just wouldn't boot. I ended up connecting it to the G4 using target disk mode in order to fix the thing. After that I tried again to boot using the CD with no luck.

Seagate external hard drives don't work after installing Mavericks 10.9

I have a 3 year old MacBook Pro. I upgraded the system to OSX Mavericks 10.9. Since then my computer does not recognize any external hard drives. I have a 1 TB Seagate external drive and a Seagate Free Agent 750 GB hard drive and my mac does not recognize either of them. Prior to the upgrade my Mac could read and write to the drives. Below is the message I receive when I plug in the 1TB hard drive.
The NTFS volume that you're trying to mount (/dev/rdisk3s1) has not been unmounted properly.
This may mean that the volume is in an inconsistent state, and mounting it with NTFS-3G could lead to data loss. You are recommended to attach the drive to a Windows computer and unmount it properly with the "Safe remove hardware" feature to guarantee the safety of your NTFS volume.
Please help.

Have you tried the recommended steps? If the Windoze machine won't allow you to safely eject, restart the computer and try ejecting again.

Ipod and external Hard drive don't work together

I got a dell optiplex gx260 which has 6 2.0 USB ports. My IPod (80GB classinc) library is stored on external HDD. When I connect my HDD to the comp and point iTunes to the HDD library everything is good and I see my songs. As soon as I connect iPod it shows up “unknown device” in a device manager. If I disconnect HDD and connect iPod only windows finds it OK, but as soon as I plug HDD back in iPod disappears. I’ve tried reinstalling sys and inf files, pointing towards updated drivers and all nothing still the same thing, tried every port and every combination on the computer USB ports still the same thing iPod and HDD don’t want to work together. Please advice, thanks.

I got the same problem here but not just with IPod. When I power up my external disk (with aux power supply) my usb stick (or IPod or printer or scanner or other devices) on other ports get disconnected. All devices did work toghether some months ago.
I think this is related to a hardware problem. Things began to fail, when I tried to co-supply 5V to a device connected to my usb bus. I possibly toasted some logic on the motherbord.
Testing your hardware on a second system may help you. Or have a look if a USB stick instead of IPod gets disconnected too. This may prove that its not IPod related.
Good luck

I accidentally updated iPhoto on my (now) external hard drive and now it won't let me access any of my photos. What can I do?

I accidentally updated iPhoto on my (now) external hard drive and now it won't let me access any of my photos. What can I do?

So, you have two versions of iphoto? One from the old machine and one from the new?
If so, forget about opening with the older version of iPhoto.
For the newer version:
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Panther crashed now external hard drive not recognized

I was away and a person that lives where I work on my computer set up his computer right next to my G4 iMac. When I looked at the screen it was trying to boot into start up mode but wasnt making it. I firgure it must have been caused by all the pluging and unpluggung.
I tried the resart disk but still has problems, so I reinstalled 10.3.9 al over again. Now its working but it doesnt reognize my external Lacie hard drive.
Ive tried restarting a cople of times, I cant firgure out what could be the trick.
Has anyone any ideas?
iMac Mac OS X (10.3.9)
iMac Mac OS X (10.3.6)
Mac OS X (10.3.6)

I would try the Combo; it's worth a try!
I don't know if the following will help with your issue , since it shows up in Safe Boot, but here it is.....
External hard drive spontaneously unmounted? Try these tips:
NEW FIRMWARE: Try updating your external hard drive's firmware, which is available from your drive manufacturers Web site--or just use VersionTracker's (www.versiontracker.com) search function to find it. Be sure to back up your data before applying the update, and carefully follow the manufacturers instructions.
OUT OF iSIGHT: If you're using an iSight camera while you're using a FireWire drive, the camera may be interfering with the drive's ability to stay mounted. Try temporarily disconnecting your iSight and moving it to a separate FireWire port. If you have multiple FireWire devices, try using a FireWire hub.
POWER PROBLEM: A faulty power adapter could be causing your drive to unmount. Your drive may not be getting enough juice to stay on, causing the drive to turn off and thereby unmounting it from your Mac. Alternately, the power adapter may not be providing a steady amount of power, causing your drive to turn on and off. Try replacing the adapter. If you can't get a replacement adapter from the hard drive manufacturer, try your local electronics store. Just make sure the adapter you choose has the same connector and input/output voltage. you can find the input/output voltage on the adapter itself.
Cheers!

External hard drive is not working on airport time capsule even after 7.7.2 firmware update.

External hard drive is not working on airport time capsule even after 7.7.2 firmware update.
I have the latest Airpor Time capsule 2gb. I specifically bought it so that I could have an external hardrive set up to wirelessly house my itunes library and movies. When i connect the drive, all i get is that the disk needs to be repaired.
the drive can works fine when connected to the macbook pro and I have run the verify and repair features in disk utility. I have also reset the airport timecapsule as well following these changes and still no change.
The 7.7.2 update says that it addressed the usb issue of not showing the drives but there are still problems as I cannot get it to appear.
Please help.
Thanks

How is the hard drive formatted?
Have you tried using a powered USB hub with the drive when it is connected to the Time Capsule?
(The USB port on the Time Capsule is borderline as far as power is concerned....you may need to use a powered hub.....even if the hard drive has its own power supply)
If the drive is formatted correctly....and....it has ample power, it will "show up" when you open AirPort Utility, click Edit, then click the Disks tab at the top of the next window.
In the example below, my Time Capsule drive is named "Backups" and another drive named "WD Drive" is connected to the USB port on the Time Capsule.
You should see the name of your Time Capsule drive (named "Data" unless you have changed the name) and the name of the USB drive if you perform the same check.
What do you see?

How do i get itunes to display my library (which is on an external hard drive)? It worked OK on old PC, but not new my new laptop. They are M4A files. are

My itunes library used to be on a PC - but shortly before the PC went to PC heaven I transferred the library onto an external hard drive. It worked fine. Now I have a laptop - but I can't get itunes to pick up the library location. I have changed in advance preferences, but the library does not display. I have tried holding down shift when starting itunes - but when I do that it looks for *.itl files, and all my files are M4A files. What do I do next?

You mean you transferred the media, not the library...
Now I have a laptop - but I can't get itunes to pick up the library location
The library location is in your /Music/ oflder.
Your media files (not yet in your new iTunes library ) is on the external drive.
I have changed in advance preferences, but the library does not display.
Because you have not yet added anything to your library.
Quit iTunes.
On the external, create a new folder named My iTunes library (or something).
Hold Shift and launch iTunes.
Select Choose library... and select My iTunes library on the external.
Go into Windows Explorer and move all the media files on the external into /My iTunes Llibrary/iTunes media/Automatically add to iTunes/ folder.

External hard drive doesn't work on any other machine but my Mac since I connected it to the Mac

My external hard drive used to work on any machine. I watched movies on my tv, putted the movies on the hard drive using my pc. Since I connected it to my new MacBook Air, it doesn't connect to anything else anymore! I hope it's something in settings witch I accedentely clicked on (something with privacy so it can only connect to my Mac or something like that). Does anyone know how this happend/how to fix it?
PS. Maybe its important, I use it for Time Machine as well. Before I used that, it deleted my whole hard drive whitch really ****** me off. Now I got new stuff on it. Maybe my Mac is just claiming it to keep the hard disk for itself?

One can't read the other.
Just to be clear Mac's can read/write FAT32 but windows cannot use OS X Extended. So to use a drive on both systems it needs to be formatted FAT32
FAT32 does have limitations and possibly the best solution is to use NTFS, a more modern, robust filesystem. The drawback here is that OS X does not natively read NTFS so a third party kernel extension is needed.

Since I upgraded to Mavericks, my Maxtor external hard drive doesn't work. What gives ?

Since I upgraded to Mavericks, my Maxtor external
Hard drive does not work. It is FireWire to
Thunderbolt . When I connect it it crashes. What
Gives ?j

Maxtor, must be an old one.
There is a disconnect occurrence in some cases with FIREWIRE ext. HD and Mavericks.
(indications mentioned on the Mavericks board)
This is known and being looked into.
Ive looked into this much myself.
Suggest using another Mac and offloading data onto a USB3 and using same until there is resolution.
Any normal USB ext. HD is working fine.
Peace

I spent hrs fixing my iTunes since I did the update and it wiped out everything! I have put all of my iTunes on my external hard drive and it works but I got a new computer. I installed iTunes on the new computer but now the folders on my ehd are empty!

I am having a very hard time. First I finally got all of my music back into iTunes and then moved them all to my external hard drive. I set up iTunes to automatically put and get music from the external hard drive and whenever I open the drive al of the music is there. Now, I bought a new computer and went ahead and got iTunes all set up then tried to add folder to import from the external hard drive but all the music folders are empty! They show the names of the artists and the albums but there is nothing inside. Please help!!

If you've just moved the drive between systems then see Repair security permissions for iTunes for Windows just in case that reveals the missing files. Apply to a single album folder first as a test. Otherwise, if you've not done too much with the drive since things went missing, an undelete tool might recover the lost media. FreeRecover looks promising... Select the drive, use the options to get file paths and check file integrity, then, presumably, you can restore anything that has been deleted that looks recoverable. Backup to another drive when you're done.

Time Machine once worked, now external hard drive is "read only"

I have a 2005 iMac G5, running OS X 10.5. Had some power issues, and reinstalled (and archived) my OS a couple of time.
Recently purchased Western Digital 1TB external hard drive for back up. It worked once or twice, but now shows "read only" status.
Disk Utility won't do anything, because it's read only (can't repair, erase, partition or convert).
Hard drive works on PC running Windows 7, and newer Mac with Snow Leopard, just not the one computer I need it for. Any suggestions?

What to do if Time Machine reports you don't have permission
This was posted in the Apple Discussions by V.K. I have only modified it slightly to be more generic.
The problem seems to be that 10.5.6 changes permissions on a file so that even the root user doesn't have write peivileges. I have no idea why they did this. The workaround suggested in [an]other post will probably work, too, but i did something less drastic. Instead of deleting the file I changed permissions on it, and it worked just fine. An added benefit is that the permission change seems to stick, so you don't have to delete the file every time you change a drive.
[Open the Terminal application in your Utilities folder. At the prompt [enter] the following command:
sudo chmod 644 /volumes/"TM drive name"/.xxxxxxxxxxxx
The name of the file .xxxxxxxxxxxx is based on the MAC address of your computer and will be different for every computer. Put the name of the TM drive in the above and keep the quotes.
You'll have to enter your admin password (which you won't see) which is normal.
This was edited by Kappy just for cleanup.
Enable Finder to Show Invisible Files and Folders
Open the Terminal application in your Utilities folder. At the prompt enter or paste the following command line then press RETURN.
defaults write com.apple.finder AppleShowAllFiles TRUE
To turn off the display of invisible files and folders enter or paste the following command line and press RETURN.
defaults write com.apple.finder AppleShowAllFiles FALSE
Alternatively you can use one of the numerous third-party utilities such as TinkerTool or ShowHideInvisibleFiles - VersionTracker or MacUpdate.
