Seagate USB drive always disappearing from desktop

I have a 2TB Seagate USB 3 drive, which is "backwards compatible" with USB 2.0.
I put that in quotes because this drive constantly disappears from my desktop. I simply
unplug the USB cable and plug it back in, and voila, there it is. But it makes me nervous
(and ticks me off!) that it never 'stays put'. Nervous, because I have been using this drive as my
Tima Machine drive. I just did a successful restore yesterday, so I know it's working properly, but
I do have to manually start my backups. I constantly get the message "backup drive not present".
So scheduled backups are sketchy to say the least. I know what you'll say - get a different drive for
use with Time Machine. A good idea I'm sure. But can anyone tell me why this drive won't remain on
my desktop? Is it a USB 3 issue?
Thanks

There are many reports in these forums of problems using Seagate GoFlex drives with Time Machine. I wouldn't trust one, myself.

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.

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.

Startup disk disappeared from desktop!

On two different Mac Pros, suddenly my boot drive has disappeared from the desktop. It used to be there, but now it's not.
Rebooting the computer doesn't fix it.
It is also missing from every Finder window's sidebar. I checked my prefs, but it doesn't show up there.
It does show up in Disk Utility. I verified the disk and repaired its permissions.
Secondary drives (drives 2-4 in the Mac Pros) show up fine.
How do I get them back?!

This was solved in a separate thread:

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.)

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.

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.

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?

Seagate USB drives appear on desktop but can't be read or ejected.

I have two different Seagate 1TB USB drives, both formatted as Mac OS Extended (Journaled) using Disk Utilities that work fine on my early 2013 MacBook Pro running Mavericks but cause various issues on my late 2013 Mac Pro (also running Mavericks). The drives will show up when connected to the Mac Pro, but when I try to view the contents of the drives, nothing appears and I cannot eject them. Sometimes, I end up with a spinning beach ball in the Finder. I have run the hardware test on my Mac Pro and no issues were detected. I have also Verified and Repaired the disks using Disk Utilities on my Macbook Pro and no issues were detected for those operations.
I'm figuring this must be some sort of driver issue, but I don't understand why the drives operate fine when connected to my Macbook Pro running Mavericks but not the Mac Pro running Mavericks. I didn't install any drivers on the Macbook Pro to get them to work, they just work.

>> also Verified and Repaired the disks using Disk Utilities on MacBook Pro
... and why would they need to be repaired on the nMP:?
It sounds like there is an issue with the port you use and assume you used the same cable.
Q: Does the case have its own power brick adapter or one of those cheaper and smaller bus powered?
Seagate does have a Thunderbolt docking station which is very nice and convenient, and of course will cost more than a USB3
Generally I recommend avoiding vendor's cases.
Seems like we need more information about the drives and case and interface etc.

External Hard Drive Suddenly Disappeared From List

Hi guys. About a week ago, a weird msg started popping up about my external (F:) hard drive, after which nothing inside of it would show up anymore.
If I clicked on a folder, there'd be nothing in it. Then if I unplugged, and re-plugged, it would all be back like nothing happened.
Yesterday, the D: drive disappeared from the population list in My Computer altogether, and no matter what I do it doesn't return. I've only tried plugging into different ports and restarting, but that's all I know how to do. I was going to system restore and
see if that helped, but this message came up on the screen:
"Changes made to drive(s) D: after this point cannot be reversed because the drive was either excluded from system restore monitoring, or was turned off or removed"
I have no idea what to do. Literally everything is on that drive. Any suggestions? And thanks in advance for any help, it'd be appreciated.

Just tried it on another computer and the drive didn't show up there either.
Its a Seagate FreeAgent Desktop harddrive.
What can I do?

My external Seagate 4Tb drive keeps disappearing on my Windows 8.1 Toshbia X75 laptop

I have a new Toshiba X75 laptop running Windows 8.1 64 Bit. One of my external drives keeps disappearing on me and the only way that I know of to get it back is to reboot, and this is getting old real fast.
I have 5 external hard drives; drive 1: 500Gb, USB 2.0 western digital, drive 2: 2TB, USB 3.0 seagate, drive 3: 3TB, USB 3.0 seagate, drive 4: 4TB, USB 3.0 seagate, and drive 5: 4TB, USB 3.0 seagate. Drives 1, 2 & 5 are connected to a powered USB 2.0
7 port hub which is plugged into one of the laptop's 4 USB 3.0 ports; the othe two drives are plugged directly into two of the other three USB 3.0 ports on the laptop.
Drive 1 has done this once before and hasn't done it since. Drive 4 is the problem child although drive 5 has done this in the past too. Both drive 4 & 5 where purchased at the same time. At first I thought that drive 4's problem was the drive it self,
so I had it replaced, but it still is a problem child. When it was replaced they gave me a newer version of the drive too.
Is there a fix via Microsoft?
I have read that there might be some sort of a fix for the registry, but when it comes to playing with the registry, I tend to make sure that I know exactly what I'm doing before hand, and right now I don't know what to do in the regestry.
Anyone have some great ideas?
And thanks ahead of time for the help.

This is probably the article that you were referring to with the registry fix:
"Help! After installing Windows 8.1, my USB drive disappears or file transfers
stop unexpectedly..."
This article was updated to state that the registry workaround is no longer required, as the Update has a fix in it. However, you still might want to check the power settings and make sure 'suspend' is disabled.
Hope this helps,

After cleaning keyboard, everything disappeared from desktop

After cleaning the keyboard, everything has disappeared from my desktop, including the hard drive disk image. I heard a "clunk" like the sound of something being sent to the Trash, but it's not there.
I know the files still exist, because when I open a finder window all the screen shots I had on the desktop are still listed under "Desktop". But they aren't visible on the desktop itself. But the hard drive disk image isn't anywhere to be seen, although it's also visible in a Finder window!
I've now moved all the files into a folder inside "Documents" (yes, I know they should have been there all along).

Sorry, everyone, I restarted and the hard drive is back on the desktop.

Why is my USB Drive Always Labeled in Capital Letters?

I have a SanDisk Cruzer Blade 16 GB USB Drive, and when ever I'm on any Mac or PC, it's always in capital letters. Name goes from "SanDisk USB" to "SANDISK USB". Is there anyway to enable it to label in lower case letters?

Because it is formatted as MSDOS (FAT32)

Disks disappeared from Desktop after 10.5.4 - 10.5.8v1.1 update

Hi,
a strange think happend today after a server update from 10.5.4 to 10.5.8v1.1 with a downloaded combo installer: After the reboot 3 of 5 1 TB firewire disks disappeared from the desktop! Just gone. What makes the whole thing really tricky: they show up in the disk utilities as mounted! Repairing them doesn´t change a thing. Disk Warrior doesn´t help. What´s even more mysterious: Opening the terminal, cd to the /Volumes folder ls shows folders for all five disks. But "ls -l" produces an "Access denied" error for each of the missing disks! It requires a sudo to show the permissions of the disks! What´s more disturbing: The permissions of the disks not showing up are ending with an "+" while all the other disks have an "@". But what really knocks me of that you can mount and work with the missing disks over the network! I really need help with that.
Greetings,
Mike

Hello mibobby,
I'm seeing something similar to the problem you reported here. I my case there are 4 external hard drives connected to the Xserve 10.5.8. All drives are visible from Disk Utility, The Finder, and terminal. However, if a drive is plugged into another system, 10.5.8, or 10.6.2, the drives will not mount in the Finder. They appear in Disk Utility, but the volume appears as a blank piece of paper rather than a hard drive icon. If you navigate to the volume vial the terminal, you get an error indicating that you do not have permissions. Any thoughts would be appreciated.
Did you ever get your problem resolved?
Thanks
Dean
