Missing firewire Drive

About every other month my external fire wire disappears off my desktop. Can someone tell me why this happens. If I wipe the drive (start up) and re install all my software I'm good, a least for a month or so.
Ideas???????????????????????

Boot off your original Install Disk while holding down the Option key at bootup to select AHT then run the extended Apple Hardware Test. Some models have a separate AHT CD.

Firewire drive missing

Hello
My firewire drive is not showing up on left of my window along with the other drives anymore.
I have my prefrences set to show hard drives. The internal drive shows up but the fire wire drive does not. The drive is available on the desktop though?
Any ideas why its hidden in my finder window?

Heal thyself
Prodding a liitle more I found that the finder sidebar prefrence was set to show hard drives in the side bar but it did not have a full check mark. Instead the pref had a dash. So I unchecked then rechecked the pref and voila' its all good.

Firewire drives missing

I have successfully had two WD firewire drives daisy chained to my mac pro for a few months. One for Time Machine, one for SuperDuper.
Lately the mac is not seeing the drives, every few hours it stops seeing them. If I click on the drive in the finder I just get the spinning beachball and the mac just freezes causing me to force a re-boot.
I have to then disconnect the power supply first and then re-boot to get the drives back. I have spoken to Apple who say it is a hardware problem and I need to take the machine in for repair.
I have also noticed that under firewire in the system profiler I am seeing an 'unknown device' as well as the two drives and my isight. I don't know if that has any relevance.
I am hoping that someone out there has a idea of what might be happening. I don't really want to take the machine in for repair as I don't want to be without it for weeks.

I think there are enough problems with MyBook to always suspect that as the culprit, and perhaps switch to another make/brand in some cases; to avoid daisy-chains possibly (I use 3rd party FW800 Aaxeon card). Most of my hard drives in the last two years are WD, but not MyBook (or LaCie or Seagate) FW cases.
Resetting the FW bus (unplug etc and power down) helps, but the cause is bad cheap equipment, cables, bridge, power).
Seeing you use SuperDuper I assume you also run Disk Warrior before/after backups as well. And backup the backups! Redundancy.

Migration assistant form a Firewire drive back to a MBP

Hi
My MBP has been returned for a replacement (3rd Time) and I have made a complete clone of the hard drive with on a fire wire drive. I would like to know if I can use migration assistant to transfer my details using the firewire drive. I don't want to do a complete system transfer, but only my settings etc like migration assistant does it. I cannot loose e-mails and reinstall everything this time round again...
Please advise.
Regards
Mike

If you made a clone of the drive, why not just clone it back on the repaired MBP. That way you would be sure all your files, settings etc. are on your new computer. The Migration Assistant will miss some files. I frequently lose monitor profiles and many apps, such Adobe CS, are broken by MA and need to be reinstalled.

Solaris 10 01/06 hard crash with firewire drive attached

I have Solaris 10 01/06 installed on a Sun W2100z workstation (BIOS is most recent available when last I checked in March). I have applied all publically available Solaris 10 patches that one can get without having a support contract.
I have an external firewire hard drive attached to the system but it's not powered on.
If I halt the workstation, power on the firewire drive, and then attempt to boot the workstation, Solaris will begin to load and then I get a kernel panic and crash dump. This happens every time.
My "mdb" skills are lacking, but if I issue:
cd /var/crash/hostname
mdb unix.1 vmcore.1
I get:
Loading modules: [ unix krtld genunix specfs ufs ip sctp usba uhci s1394 nca random fcp fctl emlxs lofs nfs audiosup sppp crypto ]
$cscsa1394_cmd_fill_cdb_rbc+0x332()
scsa1394_cmd_fill_cdb+0x6f()
scsa1394_scsi_start+0xe4()
scsi_transport+0x60()
scsi_watch_thread+0x2fa()
Anyone else having repeatable crashes on Solaris 10 01/06 x86_64 with firewire hardware attached?
Thanks,

Hi Asgorath,
Unfortunately I do not have an answer for you but I
am experiencing the identical problem on a HP
Proliant BL25p Blade Server. Here is my hardware
config:
CPU - Dual Opteron 2.6 Single Core
Memory - 16gb
Controller - HP Smart Array 6i
Logical drives - 1 (2x72gb RAID1+0)
I have tried the same things as you and I still get
intermittant boots. Power on and off does not always
work as the system still hangs. It's totally hit or
miss. Once it soes boot it seems to work fine. I have
also installed the latest Solaris 10 for x86 Patch
Cluster in hopes that some of the kernal patches
would fix the problem. So far no luck as the system
continues to hang...HARD!! HP was out to my site
today and the Eng. is going back to the group that
qualified Solaris10 on the HP Blades and see if they
have any input. If I receive anything back I will
post it here. I know this post is late and if you
have resolved please post your fix.Hi doc42755,
I have not come up with a solution as of yet, if I do come up with a solution i will most certainly post it here.
However, if you find the solution could you let us know in this thread aswell.
Thanks

Partitioning an external Firewire drive

Hi,
I'm trying to partition an external 150gb Lacie Firewire drive with the Disk Utility under OSX10.3.9 and I've gone through the Erase procedure and DU is telling me I'm left with 149.1gb after formatting.
So now under the partition tab I'm trying to set out the size of each partition and I know these sizes are gonna sound a bit random but bear with me so I want :-
3 partitions of 10gb = 30gb
6 partitions of 8gb = 48gb
1 partition of 71.1gb
After setting, naming and locking the first 9 partitions, when I get to the final partition, which I want to be 71.1gb, DU won't let me set a figure above 16.81gb.
Now I fully appreciate that disk sizes are, to a degree, 'approximate', that after formatting you do 'lose' a few gb's and that each partition will have a filesystem installed on it but where the heck am I losing 54.29gb of storage space from ?!!
I have experimented with fewer partitions and, to be fair, it seems you lose less space with less partitions but is it really the filesystems on each partition eating up that space ?
I'm using HFS+ (journalled).
Many thanks for any help you can give as this has been a real headache today !

Hi roam,
Many thanks for your continued input into this thread and my apologises for the delay in replying to your last post.
Anyway, I thought I'd give SuperDuper a go and downloaded v2.1.4 as you suggested and must agree that it's very simple to use. The backup took twice as long as my old way of backing up (restoring from the internal drive to the external drive) and I checked the log file for any errors and there weren't any, so all good there.
I again restarted with the option key held down and yet again I'm only ever presented with one drive icon to boot from, not two, so I'm really not sure why this is happening.
However, I've been giving this quite a lot of thought and I've come to the conclusion that if my internal system drive was to suffer a catostrophic failure (I'm touching loads of MDF here as I type that !!) and the drive is either wiped clean or damaged to the point that I replace it, I wouldn't be booting from my Firewire drive anyway, I'd be restoring from it, so I'd insert my install CD and reboot whilst holding down C, I'd then run Disk Utility and restore from my Firewire drive to the new internal drive.
So what I really want is a mirror image of my internal drive which is what my method of restoring via the restore route gives me.
Is that a correct hypothosis of have I missed something ?

Apple hardware test from firewire drive?

I can't find my restore dvds for my macbook. I have an image of the first disk copied via disk utility to a firewire drive. i can start my macbook from the firewire drive but i can't seem to get the hardware test to start. on the dvd you have to press the d key when the computer starts up. (http://docs.info.apple.com/article.html?artnum=303081) I can't get this to work with the firewire drive. does anyone know if this is possible. don't they do it that way at the genius bar?
thanks
-jmondo

Thanks eww.
I have booted from os 9 and deleted the ati drivers of the X.4 system folder. Now it boots and Im typing on it. I didnt run a dvd yet since I did a very basic intall, but at least the genie effect works. I understand that the cpu takes the graphic tasks when the video card cant handle, so I suppose I should expect poor performance...
But still, I wanted this machine to run pro tools in os 9, so I think I will do fine, and have x.4 for internet. I just need to test a bit more so that I dont miss a live recording thanks to the weird motherboard.
Also, the screen doesnt look very good without the drivers and it cant be adjusted in any way.
Will update if I find anything new.

Booting from external Firewire drive.

Hello there.
I got a brand new 17" 2g intel iMac and I'm very happy with it.
However I missed my 2 internal drives so I bought another firewire drive to make backups, having an emergency system, etc.
But apparently I can't install a system with this external drive (nor in the second ext. drive I got).
Is this a common issue? Do I have to do something?
(I'm using the Installer CD I got with the iMac).

It is important to note that a traditional APM partition can, in fact, boot an Intel Mac - I have done it on numerous occasions. Specifically,
- A GUID partition is required to install (new) an Intel version of 10.4.x. If the partition is APM, the installer will not recognize it as bootable and will not allow for installation. In this case, the GUID format is required.
- an APM partition can be used to boot the Intel as long as it is cloned.
I've used (and continue to use) Mike Bombich's Carbon Copy Cloner. Despite being a PPC app, it works as expected. I tested this when I first received my Intel iMac since I would inevitably need to use one drive (with multiple partitions of course) to boot a mixture of PPC and Intel Macs at work. As such, I have one external Firewire drive with 3 APM partitions - 1 with 10.3.9 (PPC) for labs that still run Panther, 1 partition with 10.4.x for labs that have upgraded and 1 partition with 10.4.x Intel for the 1 lab where the new Macs are slowly being integrated.

Where's my missing hard drive space?

I posted earlier about this, it may be a bit off topic but if anyone can offer a clue, I would appreciate it.
I got my win 7 upgrade and was waiting until vista started giving me headaches or the win7 service pack1 came out to upgrade...vista got me to upgrade today and I have to admit it was much less painful than i anticipated.
My question is about the missing hard drive space on my Idea center K230 on the box and on the side of the comp it claims a 640 HD (it claims in small print that up to 18gb may be used for the service partition) I questioned this when i first got it and even after deleting all the preloaded crap it was still saying 540 available out of 580GB....then I read that Lenovo has a huge partition for backup. So when I do my upgrade to win 7- 64 bit, I do a clean install and delete the smaller partition and reformat and expand the larger but before installing the new OS it says I have 596 available, so where the hell is the other 44GB of hard drive...did Lenovo rip us off and put 600GB hard drives in the K230's or is there a hidden partition still left that I cant find?
I am running everything off of my 596GB C: drive, I have my virus stuff and video card extras loaded, everything from the upgrade and 21 available patches and new drivers for most of my stuff....right now I am at at 575gb available and if i can ever find a printer driver that works I will create a backup point or disc from there, whatever win 7 allows. I never wanted the Lenovo one button back up and thought it was stupid to put a big glowing button on the keyboard that wipes your system back to when it came out of the box...I had nightmares of someone getting curious and going "what does this button do?"
.I notice I have a program files folder and a program files (x86) folder with a bunch of redundant files. what's the deal with this is Lenovo still hiding a backup program (maybe in that hidden partition?) that fills my hard drive twice as fast or is there a purpose for the file copies?
Any info on the above questions would be appreciated, and for those of you just looking for upgrade info I have good news, when you finally get your win7 upgrade disc it is the easiest windows installation ever, almost copmpletely automated, and very fast. So far the only sticking point is finding a printer driver, but I have 3 printers i can try, maybe one is supported.

Hi wise2u!
You can read all the details about how storage manufacturers use multiples of 1000 to measure disk space, and Windows reports it in multiples of 1024, and there is some overhead for Windows, or you can just use this rule of thumb from wikipedia:
A general rule of thumb to quickly convert the manufacturer's hard disk capacity to the standard Microsoft Windows formatted capacity is 0.93*capacity of HDD from manufacturer for HDDs less than a terabyte and 0.91*capacity of HDD from manufacturer for HDDs equal to or greater than 1 terabyte.
0.93 * 640GB = 595GB, which is about what you're seeing.
I don't work for Lenovo. I'm a crazy volunteer!

Firewire drives do not show up on network

I have a G5 with 2 external drives, 1 firewire, 1 USB
I have a G4 with 2 external drives, both firewire.
When these computers are networked,
The G5 sees the internal drives from the G4.
The G4 sees the internal drives from the G5, as well as the connected USB drive.
But neither computer sees the external firewire drives of the other computer.
I used to see these drives and made aliases for them, but they do not show up now.
I am using the admin accounts from each computer.
G5 running 10.4.5
G4 running 10.3.9
What is the cause of this problem? How can I mount the firewire drives on the networked computers?

I need to modify my question. I also have a G3 running 10.2.8
Yesterday I noticed that the Network icon in the G5 sidebar had an eject symbol next to it. That seems strange, upon reflection, as if something was not right.
I shut off all the machines for the evening.
Today, I restarted all the machines. Chose Finder->Go->Connect to Server->Browse
From each machine, I was able to see the external drives on the other machines, as well as the internal drives, over the network. I did not use nor install sharepoints. It just works (with an admin account).
However, on the G5, there is an external firewire Firelite drive. It is formatted as Fat 32.
It does not show up in the Browse window when I connect to the G5 from any computer. If I move it to the G4, it also does not show up when I connect to the G4 from any computer. So it does not seem to be related to the OS version.
In other words, it seems that since the Firelite is Dos formatted, I cannot see it on the network, even though it is a firewire drive.
So how can I fix this problem?

Has anyone been able to use an Apple Thunderbolt to FireWire to daisy chain a dozen or more FireWire drives?

Ever since I realized that I was not able to connect my FireWire daisy chain to my brand new Retina MBP there has been problems. Four months down the road, I am still unable to use my FireWire drives and have experienced terrible problems whenever I connect my FireWire daisy chain to this new Mac.
I have bought two of these adaptors from Apple now and both do the same thing. The daisy chain has been working perfectly for years with my older MBP and still does! There are no problems until I connect to the new Mac.
I have 15 various hard drives in NewerTech and DatOptics enclosures for over 22 TB. When connected to the new Mac, I would have multiple apps just hang, sometimes just Apple apps, sometimes 3rd party. I will not be able to force quit them and they will keep relauching as you can watch them in the Force Quit window. The Finder will hang and there is no relaunching it. I am having to do a force shutdown twice an hour which leaves no time for work!
After four months of this, now I am being told that Apple will buy back my Mac at full price. But I have basically lost the good part of four month’s worth of work because of constantly fighting the new Mac. This is cost me all my savings and I am about to lose a client. It certainly seems that releasing Thunderbolt1 was a huge, huge mistake.
Does anyone know of any large Fire Wire daisy chain working with Thunderbolt?
TIA,
R

Yes, my first post is all about how darn iffy the adaptors are and I have two of them to return now.
I question your answer because I am betting that four drives that are in one enclosure NOT all RAIDed together as one drive, but as four separate drives that those four drive will count as four devices. The daisy chain that I had going had eight drives in TWO quad boxes, four drives in TWO dual drives and another drive in a single enclosure. A total of five “devices” if you will, but also a total of 13 drives that were usually in this daisy chain.
Both of the Apple branded Thunderbolt to FireWire adaptors chocked BIG TIME on this and it works no problem on my older MBP. You basically can not use a new Mac when you are connected to a daisy chain like this!
Just checked the Apple website and indeed, I can get a new MBP with FireWire 800, just not with the Retina display! I wish that I would have known this five months ago before this all started!

Can't properly open fcp6 project on firewire drive on another computer

I have a long and complex fcp6 project that I have been editing with fcp6 on my piwermac g5 quad running leopard. The media and render files are each split between my boot drive and a second internal drive. I copy both drives onto a partitioned FireWire drive and then plug it into my macpro 3.1. The names on the FireWire partitions are exactly the same as the powermac drive names. The project opens perfectly on the 8 core macpro from the FireWire drive and I am able to render and other things much faster . However, I am about to outgrow the 1TB FireWire drive, so I got a larger one. I duped both partitions onto the similarly partitioned and identically named new bigger firewire drive....but when I go to open the project half the media filess are disconnected and even after I manually reconnect all kinds of error messages come up and the project is totally unworkable. So, why does the first firewiure drive work perfect but not the cloned nee FireWire drive? I even put an extra internal drive in the macpro and cloned the original FireWire to it but it does the same thing as the new FireWire, totally unworkable. I don't understand why things work perfectly with first FireWire but not with any other internal or external drive. Any help would be tremendously appreciated.

The original fiteewire which does open on the mac pro was partitioned apple partition map. The new FireWire drive that doesn't open properly is also apm, but I've erased and partitioned i GUID. I've tried using both disk utilities and superduper for the cloning in the past. I'm doing the cloning onto the guid partitions right now and will let you know if it helps in the morning. At any rate I appreciate your help.

How to secure firewire drive data for multi user mac ?

I have a couple of external firewire hard drives attached to my mac which contain all my work files.
My 6 yr son has started using my mac so I have set him up his own account and set up the parental controls etc.
BUT - is there any way I can set things up so the firewire drives dont appear to him or so he cant delete anything ?
It seems fairly straightforward to protect files files on the main hard drive but these firewire drives mount every time a user logs on and he seems to have full access to them.
Thanks in advance if you can help.

Log in under your account, and highlight the drive on the Desktop. Click cmd-i to Get Info. Make sure that, under Ownership and Permissions, you do not have "Ignore Ownership on this Drive" ticked. Now, again using Get Info, make sure that all top-level folders are owned by you, and that other users do not have access. (You might want to reduce the number of top-level folders to make this easier.)
Now log in as your son and make sure you don't have access to those folders.

How do I use a firewire drive as my start up disk?

I have a 12" powerbook that I am trying to use with an external firewire drive as my start up disk. aI install 10.5 easyily but then when I try to start up from that drive it will not recognize the drive as a Start up disk. Any ideas as to what I am doing wrong.

First, what Disk Utility tells you is correct, that SMART indicators aren't supported on an external drive. Nothing is wrong.
I might try this approach .... get SuperDuper at http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html, download it to your internal hard drive, then use it to copy your internal drive to your external drive. Make sure the option to make the external drive bootable is checked. When that's done, reboot holding the option key down, and choose the external drive to boot from. That should work with the firewire connection.

How do I install a bootable copy of Tiger to an external Firewire drive?

I've got a problem with my optical drive and cannot boot from a CD or DVD on my 17" flat panel iMac, running 10.2.8. I have bought Tiger and would like to upgrade my OS but want to be able to run some disc repair utilities on the iMac prior to doing the upgrade but can't run them on my boot disc.
I'd like to be able to install Tiger on my external FW hard drive, install Techtool pro on that same drive and then try to repair the internal drive on my iMac by booting from the external drive. Is that possible? Is it a good idea? Can I install to the external drive from my internal Superdrive without being able to boot from the install DVD? How should I do that?
Thanks in advance for any help.
Michael

Because you must boot from the Tiger DVD in order to install Tiger I'm afraid you are somewhat out of luck. However, with no guarantee either express or implied here's something you can try:
First, download a freeware utility called Carbon Copy Cloner from www.versiontracker.com or www.macupdate.com. Second, connect your Firewire drive and insert the Tiger DVD into the optical drive. Be sure it mounts on the Desktop along with the Firewire drive. Third, open your Disk Utility from the Utilities folder and use it to format or erase the Firewire drive. If you prefer you may wish to partition the Firewire drive to allocate a partition for the Tiger DVD (you will need about 6 GBs.) Fourth, open the CCC utility and click on the Lock icon beside the grayed out Clone button and authenticate. Then click on the Preferences icon. In the section labeled "Target Disk Options" be sure that the box labeled "Make bootable" is checked. No other items should be used. Click on the Save button. Fifth, select the Tiger DVD as the Source Disk, select the partition on the Firewire drive as the Target Disk. Now click on the Clone button.
Go away for a while because the clone process will take time. Once it finally completes you can eject the Tiger DVD. You now should be able to boot the computer from the Firewire drive partition. Open your Startup Disk preference pane, select the Tiger partition on the Firewire drive from the icon list, then click on the Restart button.
If this works your machine will boot into the Tiger installer from the Firewire drive. You can then install it onto your iMac. I would suggest you use the Archive and Install option. You may find the following helpful:
