Internal RAID Drives Disappeared from Desktop & Finder

A few days ago, one of my two internal mirrored RAID sets no longer showed on the desktop or in the Finder Sidebar. A day later, the other internal RAID set disappeared from desktop and sidebar. The two remaining internal non-RAID drives show up as do two external drives. All internal and external hard drives still show under Disk Utility and Photoshop Bridge CS3.
I checked Finder Preferences and boxes are checked to show internal and external drives on the desktop and sidebar. I looked at the drive detail under Disk Utility and nothing looks wrong with the two RAID sets ON-LINE. I unmounted one RAID set and re-mounted without any change. I tried unchecking the two preference boxes to not show the drives and rebooted, rechecking the boxes and rebooting and nothing changed on the desktop or sidebar.
Does anyone have any suggestions to resolve this?

Well our invisible drives problem is resolved but it's not the solution that I'd hoped for.
We visited the Genius Bar at a local Apple store and they denied any knowledge of problems with invisible drives in Macs and discounted my reports from Mac forums.
I went home and ordered a new 1tb Seagate drive. When it arrived, I installed it in bay 2, copied each invisible drive to the new drive one-at-a-time, broke my two sets of internal mirrored drives, erased all the affected drives and reloaded them. Now all drives are visible on the Desktop and Finder again.
I'm hoping that the disappearing drive problem doesn't surface again but view this as an unresolved Apple issue. Now I can look at other mass storage options for future growth.

Secondary internal hard drive disappeared from desktop after forced restart

I have three internal hard drives, one for system, the other two for data storage. While permorming a search on one of the data drives i clicked the "X" to the right of the spinning wheel on the bottom right of the search window to stop the search but the computer froze (wheel kept spinning). I then went through the dock and quit all applications, except for InDesign which wasn't responding to force quit.
The only way out was a force restart. Upon restart, one of the internal data hard drives did not show up on the desktop, nor after a couple more restarts, nor after restarting from the installation disk, verifying and repairing disks and permissions on the other hard drives with disk utility.
where did it go?
G4 Mac OS X (10.4.9) Dual 1.25 GHz, 2MB L3 cache each, 2GB DDR SDRAM

no it doesn't show up at all in those either.
Hmm. Then that sounds like the interface to the drive isn't even talking. You could try opening up the computer and making sure the cables are all connected firmly (of course, it should be off).
here's the log:
Nothing here looks too alarming.

Unfortunately, I don't see anything helpful here. It's just like it disappeared (or never existed) as far as the OS is concerned. If you can find your original disks that came with the computer, you could try running the hardware test and see if it kicks up any errors, either with a drive or a drive controller on the motherboard.

WD My Book backup drive disappeared from desktop running Lion

WD My Book backup drive disappeared from desktop running Lion !0.7.5. Disk Utility recognized the drive and has repaired it, but it still does not show up on desktop or Time Machine. My Book also appears to hold zero data now (I've had it running backups for a couple of years). What's the problem? How to remedy?

I tried this but it did not help. I did confirm that the external drive is working by connecting it to another IMac computer running Mavericks. Not sure if the recent update to Yosemite that supposedly fixed issues with time machine has messed this up or not. Trying to work with WD as well to see which side the issues is on. I remember a similar issue with Mavericks was updated making time machine unusable with the external drive.

Drives disappear from desktop

Hi there. Have faced strange situation. Sometimes when I log into my Lion (iMac 2011) account I see all the links to my internal (I have SSD and HDD installed) drives and external (USB connected) drives and sometimes I can only see my SSD drive link on my desktop. In finder, however, all the drives are visible. And in finder preferences all the checkboxes are marked to show my drives on my desktop. How to solve?
Second question is how to automount NFS drive at login automatically? Is there any way except for putting it in fstab?
Thank in advance.

William,
No...because they are not showing up on disk utility. Only the two internal drives appear. Am I doing something wrong with disk utility?

Ext hd drive and 1 int hd drive disappeared from desktop

so i fire up the old mac and i notice that both my external hard drive (used for time machine) and internal hard drive 1 have both disappeared; i went into disk utility and found the internal drive; it showed as not mounted so i mounted it; BINGO, there it is..... but, no ext drive in disk utility, so i hooked it up to my other mac and there it is in all its glory; i'm not sure what to do next;

Finder->Preferences->Sidebar->Devices->select Hard Disks and External Disks, for starters. Then, OPTION-click and hold on the Finder's Dock icon and select Relaunch.

External Hard Drive disappearing from desktop

I recently bought two external USB drives to use with Time Machine, one for my PowerBook G4, and one for my iMac.
The one that I connected to my PowerBook at home works without a problem, but the other one, not so much.
I use my iMac in the classroom, and I set everything up to work with Time Machine. No problems. The drive was recognized, I reformatted it, and the initial backup finished without a problem. Then, later, I noticed that the hard drive was no longer showing up on my desktop, and checking Time Machine showed that things hadn't been backing up hourly as they should have been.
I launched Disk Utility, but the hard drive didn't show up, so I couldn't mount it that way. Plugging and unplugging the USB cable didn't help, so I shut down the computer and turned off the hard drive. I turned the drive back on and then restarted the computer. It was back, and Time Machine immediately started running again.
But then later the drive disappeared again! I went through the same process as before, but this time I switched the USB ports before I restarted. It was back.
But then later, it was gone again.
The other strange thing is that even when I restart the computer, the drive doesn't reappear unless I've turned the drive off.
Any suggestions? Is there some auto-unmount and never come back again option in Leopard that I'm not aware of?

Does the drive even show up in Disk Utility? If so, run Disk Utility and verify (and repair if necessary) the drive:
[Resolve startup issues and perform disk maintenance with Disk Utility and fsck|http://docs.info.apple.com/article.html?artnum=106214]
[Using Disk Utility in Mac OS X 10.4.3 or later|http://docs.info.apple.com/article.html?artnum=302672]
if it doesn't show up in Disk Utility and you don't have any other copy of the files you will need to try a stronger utility such as [Diskwarrior|http://www.alsoft.com/DiskWarrior> to try to repair the drive. Otherwise you can try to copy off the files using a utility such as [Data Rescue II|http://www.prosofteng.com/products/data_rescue.php] or [FileSalvage|http://subrosasoft.com/OSXSoftware/index.php?mainpage=product_info&productsid=1]. Both have free trial versions that let you see if the software will help before you decide to buy.

IPod disappears from desktop; appears in iTunes, but is not functional

Is it possible to fix this without restoring my iPod?
Order of events:
1. I connect iPod to MacBook Pro
2. iPod appears on desktop (and finder)
3. iTunes freezes for a minute or two
4. Error message appears: "iTunes cannot read the contents of the iPod" "click Restore"
5. When I click ok: *iPod disappears from desktop/finder*
6. Only then does the iPod show up in iTunes, and *the only option iTunes gives is to Restore*
When the iPod appears +on the desktop, it has the name I gave it+.
But when it appears +in iTunes, it's just called "iPod."+ (Despite showing the correct serial number.)
Why does this happen? Can I fix it without restoring?

Update:
When I try to use the iPod now, it says "*no music*"—despite the fact that it also shows *90GB in use*.
(It's been a long time since I sync'd it, so I'm trying not to lose the data about tracks played, etc.)

Internal Hard Drives Disappeared, Finder Memory Problem

Hello Helpful Folks,
I recently installed an addional internal Hard Drive, and an additional 1GB SDRAM. This worked great for a day, but the next morning, after powering up, system was extremely sluggish, and after much deadline-induced impatient problem solving, has gone from bad to worse (system refuses to acknowledge existence of internal Hard Drives). I apologize in advance for the length of this post, but as
the devil is in the details, I figure too much info is better than not enough.
Following is a breakdown of my system: AS IT LAST WORKED; RECENT UPGRADES; and MY LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE. Please don't interpret my all caps as shouting, just trying to organize this post for better clarity.
System is dedicated to Video Editing with FCP 3, running under OS 9.2.2. System is "off the Grid", i.e. no network, no internet, no printer, no gaming devices. System was purchased new in July 2001, by a friend. At one point I know this system had an Airport card, which was removed prior to my purchase in 2003. I can't remember what else it may have had installed in its history, but here's what it has now:
SYSTEM AS IT LAST WORKED:
**bold items are upgrades Original Owner or I installed with no apparent problems**
Power Mac G4 "Quicksilver" 2001
867 PowerPC G4, 256 L2, 2MB L3
-1 Stick "ValueRAM - KVR 133 x 64 C3/512" in PC 133 DIMM slot **
- "Virtual Memory" was turned off years ago due to conflict with FCP 3
-2 empty DIMM slots
-1 60 GB internal HD (Maxtor Ultra ATA/100), 1 partition, formatted HFS+, jumpered as "Master" on Internal ATA 2 ID=0 (which as I understand it is ATA/66 speed)
-1 Pioneer "Superdrive" DVD-R/W/CD-R/W on Internal ATA 0 ID=0
-NVIDIA GeForce2 MX with 32MB SDRAM in AGP Slot, feeding a 17" Apple Studio Display.
-PCI Display Card "formacGA7" - not attached to any external device, not sure what its intended purpose is.**
-3 Empty PCI Slots
-OEM Keyboard attached to Monitor's rear USB port.
-Microsoft 3 Button Wheel mouse with "IntelliEye" (wheel is 3rd Button) connected to Keyboard USB port (right side).**
-2 OEM FireWire (400) ports
-2 OEM USB (1) ports
Peripherals that have worked in various configurations with this system over the past 3 years:
-3 OWC Mercury Elite ("Oxford Chipset") Externally powered, External FireWire(400) 200GB Hard Drives, 1 partition each, formatted HFS+, daisy-chained to either of the FireWire ports.
-1 Canon GL1 MiniDV camera, attached either to the other FireWire port, or to the last drive in the chain, depending on my urgency/laziness factor. BTW, FCP 3 has worked flawlessly controlling this Cam for logging and Batch Capturing.
Applications on System Hard Drive that I have OEM CDs for:
-OS 9.2 - (I think I remember that OS X was removed from system due to conflicts shortly after original purchase)
-FCP 3
-DiskWarrior (version unknown, purchased from Alsoft in 2003)
-OWC Intech Hard Disk SpeedTools ver 3.5
Other CDs I have:
OEM CDs for Power Mac G4:
-Software Install, OS 9.2, CD vers 1
-Software Install, OS 10.0.4, CD vers 1
-Software Restore, OS 9.2 & 10.0.4 CDs vers 1, Discs 1-4 of 4.
-OEM Apple Hardware Test; Power Mac G4, SW vers 1.2.1
Applications on system Hard Drive that I don't have CDs for, that I rarely use, but I'd like to keep:
-After Effects 5.0
-QuickTime Player 6.0.2
-Toast Audio Extractor 1.1
-Toast Titanium 5.0.2
Applications on system Hard Drive I use if my wife is busy on our Windows XP machine:
-Photshop 6.0
-Microsoft Word & Excel
# of other Applications on System Hard Drive I either don't use or may be integral to the system: 260
# of Control Panels:
-Enabled: 34
-Disabled: 0
# of Extensions:
-Enabled: 174
-Disabled: 0
note: a number of the applications and extensions are for AOL, Quickbooks, Microsoft Money and the like, as well as other things I don't use (Airport, USB printers, Networking, etc.)
Smart things I did:
-Regularly made backup copies of my FCP projects to the external drives.
-Bought a copy of MacDrive so I can see what's on my External Drives on the XP machine.
-Printed out System Profile before I installed upgrades.
-Thoroughly searched this discussion board for and gathered as much info as I could before upgrading.
Dumb things I did:
-Made a copy, but not a clone, of my System Folder to one of the external drives when I first got it.
-Didn't keep any sort of separate log of what's on the External Drives.
-Never ran any sort of Disk Maintenance, even after one of the Externals crashed (DiskWarrior saved my butt on that).
-Ignored some of the advice on this discussion board.
Really dumb thing I did without even realizing it:
Captured all media for a rush job onto my internal system Hard Drive, as well as storing and using massive jpgs for the same job on that same drive...
Which led to painfully slow rendering times, and crashes caused by "Error: Out of Memory", which I interpreted as "Must buy more memory" and not "must make sure I'm not trying to edit media stored on system drive, especially with massive jpgs that I should reduce"
RECENT UPGRADES:
Here's what I did, and how I did it:
Turned off system, disconnected all External FireWire Devices, disconnected Monitor, opened case, touched various metal parts of case and power supply to discharge any Static, unplugged power cable.
-Installed 2 512MB sticks of "Lifetime" PC 133 SDRAM; total System RAM is now 1.5GB, all 3 DIMM slots now occupied.
-Installed 1 Maxtor "DiamondMax" Ultra ATA/133 100GB Hard Drive (8 MB buffer) as "Slave" (no jumper) in top of U-Carrier above System Hard Drive; attached to middle of original Apple ribbon cable, attached available power plug.
Taped spare jumper to inside of empty drive bay, noting origin and date. Did NOT push PMU button. Carefully closed case. Reconnected Monitor, did NOT reconnect any FireWire devices. Powered System on, but did NOT perform PRAM reset.
I don't remember the exact order of what happened next, but I think: System booted up normally, a window popped up saying a new drive had been found, would I like to intitialize it?, which I did as Mac OS extended, and then named. If I was instructed to restart, I did so, otherwise did not. Clicked on "about this Mac" and saw that it now showed 1.5GB RAM. I then went about moving Media/Render files off the System drive (and one of the Externals) onto the Internal Drive, with a combination of FCP's Media Manager, and dragging from the Finder. After files had copied, dragged Media/Render files from System Drive to Trash. Opened FCP project, had FCP re-link to new locations of missing files. Saved, closed, and re-opened project, set Capture/Scratch disc to new internal Drive. At some point I changed FCP's Memory Allocation from whatever it was to 512000KB Minimum, and 900000KB Prefered (and I hope I got all those zeroes right). Did NOT restart after changing Memory Allocation, unless a window popped up instructing me to do so, in which case I did. Re-opened my project, rendered a few thing at a noticeably increased speed, saved everything, emptied the Trash, shut everything down, and called it a night as it was 4:30 am.
A few hours later, I plugged the MiniDV and an External Drive into the FW ports and powered up the System. It was behaving extremely sluggishly. I would click on something, the pointer would turn into a wristwatch (sometimes with the minute-hand moving, sometimes not) and like an actual minute later, what I'd clicked on would open. All three drives were on the desktop, still had their files, and "About this Mac" still showed 1.5GB total Memory. So I powered down, disconnected the FW devices, waited a bit, and powered back up. Same sluggish response. I tried to open my FCP project file, and instead got a Window that said something to the effect of "The Application associated with this document could not be found". I think I tried to open FCP from the Applications folder on the System Drive and got the same message (I'd only had 3 hours sleep, no coffee, my client had died, and his family was coming for whatever I had in a few hours).
LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE
Panic had set in, which never solves anything, so I don't remember what order I performed which tasks, between searching for clues in this forum, and convincing myself that that would be faster than trying to compose a question, waiting for a response, etc.
The first two things I did, and I can't remember which I did first (both from Keyboard Commands during Restart):
Rebuild Desktop
PRAM Reset
Neither of those solved the problem, so I continued.
I tried restarting without extensions.
I would get errors that said something like "Not Enough Memory to Open Finder".
I tried booting from Disc 1 of the Software Restore Disk, which only wanted to destroy my data.
I tried booting from the OS 10 disk, with the same result.
I was finally able to boot from the OS 9.2 Software Install Disk, and actually saw both internal drives on the desktop, and the 1.5GB RAM in About this Mac. I tried to allocate more memory to Finder, but was informed that "Cannot Perform Requested Operation. This operation requires versions above 8.0".
I think at this point I decided that I must have too many extensions, and started disabling ones I thought irrelevent to my cause (mostly anything that said "AOL", "Airport", "Ethernet", "Printer", "Modem", "Speakable", and a couple things called "Open TPT".
It gets worse. Then I decided to turn off some "unnecessary" things via the control panels, but somehow managed to disable the control panels themselves: AppleTalk, DialAssist, File Sharing, Modem, Mouse (as I saw that Microsoft Mouse was among the others), Remote Access, Speech, USB Printer Sharing, and possibly TCP/IP.
That certainly didn't help anything (though upon restarting from the OS 9.2 Disc I was able to see the extensions and control panels in their respective "Disabled" folders in the System Folder). But I still wasn't able to get more Memory to Finder.
So, I decided a few more PRAM resets might help, which succeeded in making both Internal Hard Drives disappear. I tried booting up from the DiskWarrior disc, but even the Mighty DiskWarrior couldn't find the drives. I performed the longer, in depth version of the Apple Hardware Tools tests, which reported that everything's fine (including the new RAM), but made no mention of the Hard Drives at all. The deadline having long passed, I shut the system down. I read through more posts and tech articles, etc.
I searched my External drives with MacDrive on my XP, and found the drive that has the copy of my System Folder (which shows all extensions and control panels as enabled); not sure if the Quicksilver will boot from that, I don't know what the Keyboard command for booting from a FireWire drive is (if there is one) and the drive itself only has 900MB of free space.
I can't find any reference to Internal ATA drives anywhere in the MacDrive documentation; if it was possible I'd put them into the XP, get the files off the Mac drives, reformat them and install OS9 from the Discs.
This is where I am now:
The Quick Silver is still powered down. I removed the Microsft mouse and replaced it with the OEM Apple mouse. I opened the case, and removed the PRAM/Backup battery (manufacture date: July 2001). Couldn't find my voltmeter, so took the bat to Radio Shack and bought a new one. Had the Radio Shack guy test the old one: it showed 3.69 volts still. Have not installed the new battery yet. The case is still open, waiting for any advice any of you might have to offer.
Thank you all so much for your patience in perusing and pursuing this.
Sincerely,
Patterson
Power Mac G4 Quicksilver 867 Mac OS 9.2.x 17" Studio Display, 512MB RAM

Thank you Rodney and John,
The jumpers are correct for both Maxtor Drives.
Rodney, you are correct in that the initial problem (slow rendering/"out of Memory" crashes) was caused by my not realizing I'd stupidly captured several GBs of media to my system drive, and not checking which drives those files were on (as I'd assumed I'd put them on one of my external media drives) once that problem presented itself.
Before I'd determined what I'd done, I bought the extra RAM. After I'd found the media files on the System Drive, and saw that my dedicated media drives were too full to easily move them, I decided to buy an additional Internal drive so that I could:
-Move the Media onto it relatively quickly and finish my urgent project.
-Juggle all my media into a more organized fashion for archiving (as most of my projects are on-going long-term affairs)
-Wipe it, Partition it, and clone my System Drive onto it, as a spare bootable drive in case my OEM System Drive failed.
Copying the Media files onto the New Drive and moving the System Drive's Media files into the Trash worked great: huge improvement in Rendering, etc.
Before shutting down for the night I Emptied the Trash, and was pleased with the amount of space I'd freed up on the System Drive.
My guess is that the System Drive was terribly fragmented, having been subjected to intense use over the past 5 years without any sort of Drive Maintainence, and deleting that massive amount from it in one shot caused my extreme system sluggishness upon Startup the next day.
My subsequent lame attempts to solve the sluggishnes ultimately resulted in my losing access to both drives.
Today, I replaced the Backup Battery, pushed the PMU, re-attached the AC, and Powered Up with the case open as per your suggestion.
It was trying for a few minutes (the gray screen went black at one point, and then returned to gray) before presenting me with the flashing question mark.
There was, however, a quiet but distinct "buzzing" sound that would alternate: 1 sec "buzz", one second silence, one second "buzz", one second silence, etc. coming from the drives, even after the "?" appeared.
I powered down, removed the Ribbon and Power Cables from the new "Slave" drive, and powered up again, with the exact same results.
I powered down, removed the Ribbon and Power cables from the original "Master" drive, reinstalled the Jumper on the New Drive as "Master", plugged the End of the Ribbon and the Power cables into the New "Master" drive and powered up. The screen went to the "?" within 20 seconds instead of 4+ minutes, and no more "buzzing".
I put the Apple Hardware Tools Disk in, ran the "long" test, and everything came out fine.
I have to abandon this for now, but thanks again for your previous advice, and any more you may have!
Cheers,
Patterson

My second internal hard drive disappeared

My second internal hard drive disappeared a couple of days ago taking many gigs of iTunes with it. It does not appear on the desktop, finder or anywhere else. When I click on a song in iTunes I get "The song “Cowell: Set Of Five - 4” could not be used because the original file could not be found. Would you like to locate it?" When I try "locate," well it shows me the Main Disk. Not helpful. I've read lots of posts about vanishing drives and crashing drives on Leopard (I run Snow and was about to go to Lion). Did my drive die or did it go into the witness protection program? Irony is that I bought a 2 TB external drive last week to back up the iTunes drive and procrastinated. Suggestions? Experiences?

Is it listed in Disk Utility?

Gspeed ES Pro RAID keeps disappearing from Mac, have to re-initialize!

UPDATED VERSION:
MAC PRO KEEPS LOSING CONNECTION TO RAID DRIVE.
After 9 months of organizing a documentary film edit on an external RAID drive (12TB, Raid 0. Yes, I have 2 layers of backup), I purchased the PNY Nvidia Quadro 4000 video card for the primary edit. Soon after, I began having boot up issues. The screen would freeze at various points during the startup process, requiring manual power-downs.
Over the past two months, my computer has lost communication with the RAID 3 times, forcing me to rebuild it from my backup drives (10TB). One tech at Diskwarrior said my computer lost the partition, and that the 1s and 0s had been largely replaced with gibberish.
The Raid becomes unrecognized by my computer in one of two ways:
1- After two days of copying data back over to the raid (rebuilding it), I get an error code -36, saying a file cannot be read or written, then the Raid partition disappears from disk utility and the next time I start up the computer says it doesn’t recognize my drive. The ATTO configuration tool (the card that attaches my raid to the computer) sees the drive, but my computer does not. I have to re-initialize it and start over again.
2- The Raid will go from being recognized to not being recognized when I reboot one day. Again, I have to re-initialize and rebuild.
I removed the PNY Graphics card and put in the stock ATI Radeon HD 5770 it came with. On day 2 of rebuilding the RAID, I got the error -36 and the Raid disappeared from disk utility again. When I opened the raid folder, which seconds before had 10 TB of data on it, it read as zero items. So the PNY Nvidia card was NOT the problem.
Apple has worked on the computer 3 times, running extensive hardware tests, but the same problem persists. At one point they said my blackmagic card was the problem, and more recently they said I probably have bad ram. I tried separate ram (the old 6GB my computer came with), and my computer seemed to begin booting up okay, but one day later I had the -36 error, the RAID couldn’t be recognized again and I lost the data during another rebuild. Apple even replaced the Ram Tray, but the same problem persists.
G technology says my RAID’s hardware is fine, and ATTO, who makes the Raid card, says it looks fine to them too. This does not mean they are 100% not the problem though.
Yesterday as I was attempting to rebuild the RAID again, I saw the -36 error come up, and files stopped copying. I immediately made a screenshot and noted the time.
Today I spoke with a really cool tech at Apple named Ron who helped me investigate the Kernel log, and this is what it said (the RAID is called FadingWest):
Dec 6 17:05:36 Jesses-Mac-Pro kernel[0]: hfs_swap_BTNode: invalid forward link (0xbb739311 >= 0x0000df00)
Dec 6 17:05:36 Jesses-Mac-Pro kernel[0]: hfs: node=2717 fileID=4 volume=FadingWest device=/dev/disk3s2
Dec 6 17:05:36 Jesses-Mac-Pro kernel[0]: hfs: Runtime corruption detected on FadingWest, fsck will be forced on next mount.
Ron believes my problem is with the RAID card. He thinks it’s dropping the connection. So I’ve got an RMA going with ATTO for a new one.
Here are the final things I can troubleshoot at this point:
New RAID card (ATTO)
New RAID drive (G-Technology)
Motherboard / PCI lanes (Apple).
NEW COMPUTER (Apple)
Any ideas are appreciated. Here are the items in question:
Mac Pro mid 2010 2x2.66 Ghz 6 core Intel Xeon OS X Lion 10.7.5
G speed ES Pro (G Technology) – 12TB @ RAID 0
ATTO R680 RAID card

I found this on another help site, I think it's the trick:
there are 2 halves to the Dock. With a bar in the middle.
on the left side, there are 2 sections. the furthest left are the icons that will stay in the dock, then on the right side of the left half of the dock, are the temporary icons, the ones that just stay there till the program is done.
You can freely move a temporary icon to the left and it will be come a permanent icon.
I am reminded of the wizard of OZ here... you could always get to firefox... you just had to click your mouse (and drag an icon)..

Microsoft word disappeared from desktop

Microsoft word disappeared from desktop. Can I just load it off of DVD that was used originally to load it on the imac? Do I need to remove microsoft office first (other office items are still there)?

If it's the Dock that's missing the icon, you've not really lost anything. Open Applications > Microsoft Office and find the Word app:
Click and hold on its icon and drag it to where you want it in the Dock to restore it.

Will Apple stores in Germany replace your iPhone if there is internal hard drive problems from a phone from the US. I am studying abroad and won't be home until December

You can try, but the iPhone warranty terms state that Apple "may" restrict warranty/service to country of original purchase...key word here is "may".
Good luck.

Why does my external drive disappear from my desktop?

I am switching from PC to Mac. I have 2 externaldrives. Both have been formatted in FAT 32 by the MAC. When I plug them in the desktop and finder see them, then with both of them they have disappeared from the desktop and from finder. Still can be seen in disk utility and system profiler. How can I find them and why does this happen?

If you daisy chained then try without. May not be enough power to handle both at sme time. Other than that read some info:
1. Shut-down your Mac, and unplug the power cord
2. Turn the power off on your external FireWire devices
3. Unplug the FireWire devices from the Mac
4. Wait for 5 min.
5. Plug the power cord to your Mac only
6. For PPC Macs: Restart the Mac while holding the Option-Apple-O-F, and keep holding until you get the ">" prompt, then release the keys
7. At the ">" prompt type:
      reset-nvram and hit the Return key
      set-defaults and hit the Return key
      reset-all and hit the Return key
the last command will restart your mac
8. Shut down your Mac
9. Connect all your FireWire devices to the Mac and turn them on
10. Restart your Mac.
All your FireWire devices should reapear, if not repeat the procedure
How to avoid the issue :
The only really proven way to avoid burning up a FireWire port is to connect all devices and to turn them on PRIOR turning on the Mac. Likely, one must unplug them and turn them off AFTER the Mac has been turned off. If you need to connect another device, then you're on for a shutdown of your machine...  It's a tad annoying but it guarantees that the FW ports won't be damaged.  Be careful when using self powered devices such as webcams, iPods, hard drives or hubs, as they can destroy the port pretty easily. Another thing is to avoid daisy-chaining hard drives.
When the FW port doesn't respond anymore :
In this case, peripherals won't be mounted upon plugging, and won't be displayed in Apple's System Profiler. The self powered devices will still be fed by the port, but won't respond either.  It happens that the PHY just hangs after a surge or a random problem. Once hung, the port will not respond any longer, it is possible to reset the component by going through the following steps :
1° boot the PPC mac in Open Firmware by holding [ Apple key - Option - O - F ] after the startup chime.  2° you'll get to a command prompt. the keyboard mapping will be QWERTY, so pay attention when you type the following :  RESET-NVRAM (enter)  RESET-ALL (enter)  3° Now the mac should restart itself and the port should function properly again.  If it still doesn't work, then it means that the PHY is damaged.

From Kappy post:
922 is only used in dual drive cases to provide a "build-in firmware RAID support"
912 or 912+ is FW800, the "+" means USB2
911 is FW400
924 adds eSATA support along with FW400/800
MacSales, OWC Tech Support library is where I would go first, as they do tend to have or links to, firmware updates for Oxford.
From Wiebetech:
I just upgraded my Mac OS, and now I'm having trouble with my FireWire device. What can I do?
A: With nearly every OS update Apple releases, some external drives are not recognized after the update. The typical symptom is that the device will not mount but the volume is visible and grayed out in Disk Utility. This means that the device is working properly, but the OS does not recognize the volume as mountable. Sometimes the drive does not show up at all.
The first thing to do is to see if repairing Permissions with Apple's Disk Utility First Aid feature solves the problem. If not, try repairing the disk with First Aid. Another possible solution is to zap the PRAM. This is done with a keyboard command while rebooting. Restart your computer and hold down the Command, Option, P and R keys. Consult the Apple web site for details.
If this does not work, then try pushing the PMMU reset button on the logic board. Consult the Apple web site for locations of the button for your Mac. If the drive still does not show up, shut down, disconnect all peripheral devices, and boot from the Mac OS Installation CD. The later the OS version, the better. Do not reinstall the OS, but when the Installer is loaded up and ready to begin, go to the File menu and use the Disk Utility program. Connect the drive that is having problems, then start the Disk Utility application. If you see the external drive and it is not grayed out, you know the drive is okay. Run Disk First Aid on it anyway. Then run it on your internal boot drive while you are at it. When done, unmount the external drive and UNPLUG it! Then restart the Mac.
When the Mac has restarted and is running on the internal boot drive, reconnect the external drive.

Network Drives Disappear from Finder Intermittently

I'm periodically having problems with my Mac recognizing an Iomega Home Media Network Drive. Everything's connected together using an Airport Extreme. Usually the drive will show up under the "Shared" category in the Finder, and I can connect and use it normally.
Every once and awhile, it disappears from that list. I can still connect manually using Go->Connect to Server, but the Finder doesn't pick it up on its own. After a few days or weeks, it'll just show up in the shared list again. No amount of restarting/repairing permissions will fix it. For example, my drive has been missing for about a week now, and after doing nothing special it decided to show back up while I was typing this post.
I've seen this topic come up periodically on the boards, but I couldn't find anything recent or with a solution. Has anyone encountered or come up with a fix for this?
Thanks,
-Jason

I have an Iomega drive that is also fidgety on the network, either in Leopard (when problem arose) or SL (when I found my solution). I actually had to view my drive under the sidebar path ComputerName> Network> AirPortEx> Iomega Drive because I kept getting errors when I tried to view in column view from the shared section despite having the drive set to ignore permissions.
Firstly, this is what I call a workaround, not a fix, as recognition of the drive doesn't work seamlessly in Finder as advertised, but required these extra steps in order for me to always see the drive in the sidebar. Secondly, it may not be absolutely necessary to do all these things, and I am assuming you have the authority on your network to do all these things, but here's what I've done to get my satisfaction:
1. Make sure you set servers to mount on the desktop in Finder prefs and that connected servers and bonjour computers are set up to show in the sidebar
2. Use connect to server if you have to and mount the drive to your desktop
3. Once the drive is on your desktop, open system prefs and go to your login items under Accounts & Authenticate by clicking the lock on the lower left and entering your password
4. Drag the network drive into your login items (and dock, sidebar, or window toolbar if desired)
5. Restart
This may not be the fix you hoped for. You do seem to have to keep the drive mounted, etc. But I do always see it in my sidebar under sharing now, and have no problems viewing anything on it from wherever in the Finder I try to access it (whether from the sidebar in the shared section or under the network area of my computer, in the dock, or from the toolbar). At the very least you never have to Connect to Server again. Hit the drive icon in the dock and it will connect if you get disconnected.
FYI: Make sure you always choose the "ignore" button when/if alerts pop up to tell you that you have been disconnected from the drive because you'll have to remount otherwise. These alerts occur to me only when waking my MBP from sleep. I wait 2-3 seconds, and click on the icon of my Iomega drive that I have in my sidebar, toolbar, or dock and it shows contents just fine, still connected after all.
