Firewire 800 and Iomega 2Tb External Drive

I started using an Iomega 2Tb as Time Machine just over one year ago.
Initially it connected to my iMac 27" and worked perfectly with a Firewire 800 cable.
After a couple of months it suddenly stopped working and was not recognised in Finder or Disc Utility. I contacted Iomega and they suggested I try a new cable. I did and it did not make any difference. I have no other Firewire devices to test if the problem is with the Iomega or my iMac.
I switched to USB and that worked perfectly for a while. I have subsequently had problems with the Iomega "unmounting" itself, with a Journal Error comment when I run Verify in Disc Utility.
I have reformatted and remounted the Iomega twice but it has unmounted itself again.
I rotate three external drives as Time Machine back ups. The other drives are USB Freecom and Seagate 1Tb drives. They continue to work perfectly.
Because the Iomega has also given problems when connected by USB, I suspect it is the cause of the problem.
I would hope that we have reached the stage in home computing when we can buy a device, plug it in and it works, without having to waste time problem solving.
Can any one suggest anything else I can check?

Thanks Nick. The Iomega is the only external drive with which I have experienced any problems so I guess I wasted my money and will need to try another brand.

I recently moved and had to disconnect my WD My Pro Edition II 2TB external drive I had been using for backup.
Its been several months (many upgrades to the iMac software during this time), and now when I try to reconnect the external dire (Use a firewire cable) it does not recognize the drive is there. I also tried "reloading" software from the Western Digital site, but after following all the instructions, it looks like my iMac doesn't support this software (I can't even locate it after I follow all the instructions.
Thnaks, for anyones ideas on how I can get this working again.....

First of all, you do not really want to use their software; if you want a bootable clone, use either Carbon Copy Cloner or SuperDuper. If you simply want to drag and drop some files, you don't need software to do that. The important thing on any external drive is that you format/partition it correctly (Mac OS Extended (Journaled) and using GUID partition scheme).
Unfortunately, I don't know anything about WD drives or their software, so I don't have any idea what kind of backup you did. Having said that, it should still recognize the external even if it's outdated. Have you tried mounting it manually in Disk Utility? If you can get it to mount, you could (worst case scenario) just drag your stuff off onto your internal and then reformat the external.

Firewire 800 is the fastest and most reliable. Also it's bootable if you hold the option key down on a wired or built in keyboard. Not bootable via Airport obviously or if Filevault is used.
It's only your first clone that's usually takes the longest, it's shorter when it updates as you only do the changes which you can control to keep a pure clone if you wish.

Mixing Firewire 800 and 400 on an iMac?

I have 2 external FW 400 drives on my late 2011 iMac. I use an 800 to 400 adapter. I've been thinking of getting a new external drive from OWC. The have both 400 and 800. The 800 case has 2 800 connectors and one 400. Does it make sense to mix? Will they all run at the slowest in the chain?
I was thinking of connecting the 800 directly to the iMac using the built-in 800 connection. Then chaining from there using the 400 connection to the other existing 400 external drives. Will I actually get 800 speed on the first drive?
Thanks

I have a mixed group of external drives, and just bought a new OWC Mercury quad interface drive.
The user manual that came with it says:
Note: If you are using FireWire 800 and add a FireWire 400 device to the chain, all devices will be reduced to FireWire 400 performance
I tested this myself, which confirmed it. I set up the following chain, with the first 2 drives connected by FW800, and with a FW400 drive either connected or not connected at the end:
HD ----800-----DRIVE1------800------DRIVE2-------400-------DRIVE3
I booted from my HD and timed the copying of a large file from DRIVE1 to DRIVE2. Although the FW400 drive was at the end of the chain and was never involved in the copying, just having it attached immediately reduced the speed of the file copy from Drive1 to Drive2. The actual speed reduction in practice was about 40%, not 50%.

WD MyBook Firewire 800 and M-Audio FireWire 1814 conflict

I have a big problem with an external HD Western Digital MyBook firewire 800 and a M-Audio firewire 1814.
When I turn on the external HD (connected via firewire 800) the sound card stops to play.
If I don't use the drive everything works, but if I use the external HD the sound stops again.
If I connect the external HD via firewire 400 or usb2 the soundcard works perfectly ...
I think there is a conflict in some driver but I do not have any soundcard (firewire) or any other external drive (Firewire800) to check WHERE is the problem.
I have the same problem in both my Macs (iMac 24 Aluminium and MacBook Pro 17")
Does anybody can help me? Am I the only one with this problem?
Do I have to complain with Western Digital, M-Audio or Apple Inc.?
Thank you for your help!

Thank you Chris, I just wonder why Bee Jay can use the HD FW800 with the M-Audio Firewire interface without problems.
I use the ext HD for backup too, but sometimes I need to find something in my backups and I have to turn off the audio interface and copy the files on my internal HD ... then turn off the drive again and turn on the M-Audio ... it's very annoying.
In some forum I read that the problem can be the firewire chipset, but my iMac has the Lucent and the MacBook Pro has the TI (reccomended by M-Audio) ... same problem on both machines.
I did some test:
1) If I use the FW800 external HD and the FW400 with iMovie and my Video Camcorder I have no problem at all. I tried to use the HD at maximum (during a time machine backup I was copying other files and saving the HDV files in the same external HD) and everything works perfectly without loosing a single frame.
2) If I connect the HDV camcorder to the M-Audio interface I cannot even start the capture ... I have to turn off the external FW800 HD.
It looks that the problem is definitely in the M-Audio Firewire driver but unfortunatley the M-Audio e-mail support is only for US customers ... and I'm Italian.
Is there any US customer that has this problem and can insist with the M-Audio support?
Maybe they can solve it in the next release ...
Thank you in advance.

My WD 2TB External Drive can't be formatted.

Hi there,
Something really mysterious happened last night and it has completely stumped me.
I have a WD 2TB External Drive that I use with my iMac and Macbook Pro, it's formatted FAT so that I can use it on Windows aswell. This setup has worked well until last night. I plugged the external into a Win PC and it didn't want to pick up. It showed the drive letter and drive but not the usual name. It gave it the generic windows name and when I clicked on the icon nothing happens. When I ran disk management on Win it shows the drive is healthy but that it has 2TB free space which is obviously not true since it had 1TB free space.
I decided to safely remove it and plugged it into my macbook pro. It then also didn't pick up and only showed up in Disk Utility with the partion grey'd out. I tried for a couple of hours to verify the disk and repair the disk in Disk Utility and it would run and complete both but then when I tried to mount it in Disk Utlity it would say it can't.
I then thought the drive is fried so I downloaded Drive Drill to see if I could access the content on it to restore my lost data. I ran it and it picked up the drive and restored 100% of my lost information. I then tried to format the drive but everytime I delete the partition and format it it gets stuck on a certain position and won't do anything for hours.
I know the drive works fine because initially I left it and it eventually formatted the drive and it picked up on the dock. I then tried to copy information over to it and after 100GB it got stuck and wouldn't do a thing. I then decided to format again because I suspected some files that were corrupt might have been transferred over again when restoring the data on it.
Now my problem is that it shows up in Disk Utility and I can run verify and recovery but as soon as I want to format it doesn't work and it stays stuck at the point of formatting the drive.
I have already tried the following:
- A different USB plug
- Formatting in Windows
- Different Formats (ex-FAT, NTFS etc)
- Completely removing the partition and creating a new one
Here are screen shots of what it says when I verify and recover the drive:

Thanks for the feedback Linc,
I have tried to repartition it and I also tried to delete and format, all of it takes time and finishes the process but then when I tried to mount it says it can't mount the drive and neither does it pick up on Windows. Very confused!

Can I use a 2tb external drive with Time Machine to backup my Mac Mini (256gbSSD + 2tbHDD)?

Can I use a 2tb external drive with Time Machine to backup what I have on my Mac Mini?
My Mac Mini has one 256 SSD and one 2tb HDD. I want to use Time Machine to do a backup of everything.
Would an external 2tb My Passport Drive by Western Digital work for the backup?
It seems like it would not work because the total storage on the Mac Mini is 2304 gigabytes (SSD + HDD).
And the external Western Digital drive is only 2048 in gigabytes versus 2304 gigabytes the Mac Mini has.

No. A Time Machine backup drive should have at least twice the capacity of the drive it backs up. You would need at least a 4 TB backup drive for Time Machine.
Might I suggest as an alternative that you not use Time Machine but a third-party backup utility that simply overwrites older files with new ones such that the backup drive can be the same capacity as the drive backed up.

How do I install windows xp on a 2TB external drive osx 10.6.8?

How do I -OR- CAN I
Install Windows XP on a 2TB external drive OSX 10.6.8?
I WILL get another 2TB to back up to 1st!
Should I start over with the New 2TB Drive and put the XP & OSX partitions on it 1st?
BTW... Anyone have an idea where I should send a WindowsXP drive that has the click of death syndrome to get the data off it?
Thanx Y'All
OKMatthew

Microsoft doesn't allow users to install Windows on an external drive, so you can't do it. Instead, install Windows in the internal hard drive through Boot Camp.
Respecting to your second problem, there are companies that recovers data from your hard drive, so you may want to contact with them

Can anyone recommend a good 2TB external drive for my iMac 10.9 ?

can anyone recommend a good 2TB external drive for my iMac 10.9 ?

The Griffin Survivor is a military-grade case that I use. It's $40 and I purchased it at Best Buy. It has a rubber piece that covers the charging port, but can be easily removed for charging while still in the case. The only downside of the case is because of the added girth, it makes the iPod unusable with iHomes or other docks unless you take it out of the case.

My firewire 800 and USB ports on not functioning!

My firewire 800 and USB ports on not functioning, I believe it is an issue the next driver loaders anyone, know how I can reset these?

You don't "reset" a driver (kext). And I don't believe it s a driver problem. However you might try doing a smc and pram reset to see if that "shakes the ports loose". Might work. Couldn't hurt to try.

Rear Firewire 800 and 400 Ports

I'm having an issue getting a new Maxtor HD to be recognized by my G5. The front FW 400 port works fine, but I can't get the two rear ports to recognize the unit.
I've tried the shutdown and power plug pull technique but that didn't work.
Any other ideas?
Or does this box have to go in for repairs?
??? Thanks

You could try the Official firewire reset

"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.
http://docs.info.apple.com/article.html?artnum=88338
Here is a summary:
* shut down and disconnect all external drives and peripherals ; make sure nothing is connected to the FireWire ports
* use Apple Disk Utility to repair permissions on your internal boot drive
* 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
* reconnect AC power to only the computer (battery too if laptop)
* restart computer
* verify that FireWire ports are visible within Apple System Profiler
* reconnect FireWire drive (only one); refresh window within Apple System Profiler to rescan the FireWire bus; confirm that drive is visible
* confirm drive is OK by using Apple Disk Utility and apply First Aid
* repeat for other drives, one at a time "

I'm using Time Machine and a LaCie external drive to backup. I also have a 8 GB LaCie flash drive I want to use for small jobs. If I plug the LaCie flash drive in, is my Mac going to think it is the LaCie external drive and start trying to backup?

FireWire 800 and 400

Can I link up two HDD's one FireWire 800 and one FireWire 400 into one FireWire port on my MBP?
Thanks

It is just that easy. I'm assuming you have a FW800 on your MBP? Just do a search on Amazon for Firewire 800 to 400 cables and you'll find some - very inexpensive - that will suit your needs. Oh! Here are some from monoprice - all under $9.

Is there a difference between firewire 800 and firewire 400 besides the connectors

is there a difference between firewire 800 and firewire 400 cables besides the connectors?

Speed. 800 is up to twice the speed, and sometimes faster. You can connect the two connectors with a cable that fits both ends, but you will be left with the slowest speed.
