Finder wont recognize my external hard drives (NTFS), even when disk utility does, just after upgrading to OS X Mavericks!

After installing OS X Mavericks, my 2 USB HD don't show up in Finder, but do appear in Disk Utility. With the previous OS X had no troubles!
HD1 Hitachi 1TB / HD2 SAMSUNG 1TB

If they show up on the Desktop baltwo is correct since the finder does see them but the default preference hides them from the sidebar on the left.
Click the word finder by the Apple and choose preferences.
Choose the tab along the top that says sidebar.
Check away at those boxes.

Time Capsule wont recognize my external hard drive connected to my router.

I purchasd a Netgear N600 Ruter and connected a WD MyBook for Mac Hard Drive to it with the hopes of setting up a wireless Time Machine Backup system for my MacBook and iMac. Unfortunately Neither computer will recognize the MyBook Hard Drive as a Hard Drive for Time Machine. I can get to the files through the finder window just fine, but Time Machine won't recognize it as haveing space to back things up in. In disk Utility it stays that my external Hard drive is formatted to "Macintosh Formatting".
Also in Time Machine>Select Back Up Disk>Other Time Capsule>Set Up it opens the Airport Utility. In Airport Utility If I go to File Menu and go to Configure Other it Requests a address and password. For the address I chose the files that the Hard drive is listed to which is smb://192.168.1.1...(etc) It says "An error Occured while reading the configuration." Do I need to reformat my external hard drive? I was on support for about 2 hours with the Router support and they finally said to contact apple Support. Any Ideas would be great. Please Help!

Netgear made WNDR3700 and WNDR3800 as well as a specific Mac version.. all called N600 as well as some modem models also called N600.. So tell us a precise and exact model number.
I think the Netgear are supposed to handle AFP file protocol, but we need the exact model to check... also if it can handle AFP since Lion.. because a lot of things changed and units that could do TM backups no longer worked. AFP in Lion increased security beyond what the firmware of the router could handle.
You also need to understand, you cannot see a TM backup that was done on an external drive if it is plugged into a network device.. TM handles network drives differently to local drives.
But there is no reason to do what you are doing.. In fact it is much better to leave the disk plugged into the iMac.
You can still access it from wireless with your laptop, by simply sharing the disk to the network from the iMac.

Wont recognize all external hard drives

I have 3 WD external hard drives daisy chained together and they were all working fine until my computer crashed and was disconnected. Now it wont recognize number 1 external hard drive but # 2 & #3 hard drives are recognized, i then disconnected them all and reconnected them and now #1 & #2 are recognized but number 3 isn't and the strange thing is when # 3 was working #2's light was off but it worked, now after the reconnection # 1 is working but it's light is off. So they all seem to work but not all together like it was

Same problems off and on. I fix it by plugging the drive into my Timecapsule and it gets mounted right away. Later, when I attach it back to the Mothership the drive will come up. Not sure why this works, but its worth a try.

External hard drive not visible in disk utility or finder

Hi all,
I have had a good look through previous discussions and I can't seem to find an issue relevant to mine.
My external hard drive has 2 partitions (1 time machine back up, 1 general hard drive). The issue is that the HD is running when it is plugged in however it is not visible in either disk utility or finder.
I am running OS X 10.10 (Yosemite) on a 2010 MacBook Pro. I also have parallels desktop running windows 7. When I boot windows and plug in the HD I usually get the option to mount the HD to either OS X or Windows. With this issue the option window appears for a split second (not enough time to select either) and then disappears. It seems that the HD may be ejecting itself as soon as it is registered by the computer. I have tried using a different power cable for the HD and also a different usb cable, this doesn't help.
The external HD is a Samsung D3 Station, which i have had for 6 months now and never had an issue with.
Any help is appreciated
Thanks,
Bruce

An update for anyone who can help me:
I have tried the external hard drive in other computers (mac and windows), each time I get the same problem above.
I have removed the HD from the enclosure and purchased a docking station for it (3.5" SATA). When I plug it in to the laptop it disconnects itself straight away before it is visible. With the windows computers it installs the drivers and says that the device is ready to use, then disconnects before it shows up.
As the HD is not visible there is no option to re-format or anything.
This is very frustrating as I was using the HD with no issues and it randomly disconnected and I have not been able to access since.
Thanks in advance for any help.

Iomega external hard drive not appearing in Disk Utility

I have a MacBook Pro (from 2011) and I'm running OS X 10.9.5. I have an old Iomega external hard drive. I'm not certain but this thing might be about 3-4 years old? When I connect the drive to my MBP, it shows up in Finder under Devices. But what appears is the Windows disk utility that is pre-loaded on the drive. The actual drive does not appear and I can't move files onto it in Finder.
When I go into Disk Utility and try to format the drive for Mac use, it doesn't appear.
Is there anything I can do or am I stuck with this old drive that doesn't work with Macs?

External Hard Drive won't load, Disk Utility and System Profiler crashes,

I've had the WD 1TB Passport for Mac for about a year now and as of this afternoon, my MacBook Pro stopped recognizing it. It's encrypted so when I plugged it in, my computer asked me for my password, but then it said there was an error and wouldn't mount. After restarting the computer, the password prompt for my external drive didn't even pop up. I can hear the hard drive spinning and the light flashes for a good 30 seconds before going solid. I have tested my USB ports with flash drives and they are reading them just fine. I tried to run Disk Utility but it goes into the never-ending loading mode. So then I go to the "About my Mac" page and clicked on storage, and the profiler crashed (never-ending loading). Can anyone help me? It was working just fine up until today. I even tried different Micro USB chords on it. This drive is incredibly important to me and I would appreciate not having to erase anything from it (kinda defeats the purpose of backing up a computer if the external hard drive is the one needing the backup).
I have a
Mid 2010 13in MacBook Pro
OS X 10.8.2

External hard drives not showing in disk utility

When I connect a new Eagle/Consus W-Series external hard drive enclosure to my 15" PB, the hard drive doesn't show-up in the left hand pane of the Disk Utility window. The only thing that shows is the drive in the PB. The hard drive in the enclosure is a WD SATA and is connected via USB cable. The same thing happens, or doesn't happen, when I'm connected via ethernet to my G5 2.3GHz Dual Core: when I open Disk Utility on the PB, the drive on the G5 doesn't show. What I'm trying to attempt is to mirror/clone Tiger from my PB onto the new, to me, G5 using SuperDuper.

Hi, Bob. I obviously didn't understand the situation properly, and now that I realize that, I'm afraid I still don't.
When the G5 is connected, via ethernet to my PB, the hard drive does not show-up in the PB's disk utility pane.
The G5 doesn't have a hard drive in it now, is that correct? So why connect it via Ethernet to the Powerbook?
If you're trying to clone the Powerbook's hard drive onto the G5's drive inside the external enclosure, all that needs to be connected is the external enclosure to the Powerbook, via USB cable. The G5 itself isn't involved in that process at all. When the G5's drive is in the enclosure and connected to the Powerbook, does it appear in Disk Utility on the Powerbook? If not, see my previous suggestions, with the exception of my comment about it not working with either computer.
If the SATA hard drive doesn't appear on the Powerbook's desktop or in Disk Utility when it is in the G5 and the computers are properly networked via Ethernet, recheck your sharing settings: the G5's drive must be shared to be visible to the Powerbook. In that mode, you may not be able to clone the Powerbook's drive to the other one, because the drive in the G5 is being used to run the G5. But if the G5's drive is partitioned, you should be able to clone the Powerbook's drive, via Ethernet, to a partition other than the one which contains the OS that's running the G5.
While the hard drive is in the external enclosure, I can hear it spinning, and am assuming that all the connections are working properly.
If the drive spins, you can be sure it's getting power, and that's good. But you can't safely conclude from that that any or all of the data connections are working properly; in fact the evidence suggests the contrary.
In short, there may be not one but two problems at work here: incorrect sharing settings when the two computers are networked, and a bad cable, connection, or enclosure when the drive is connected to the Powerbook via USB.
EDIT: Let me also add that if the only Tiger installer discs you have are the ones that came with the Powerbook, then having copies of that Tiger installation on both of your computers would be a violation of the software license that accompanied those discs, which entitles you to have Tiger installed on only one computer at a time. If that's the case, you should really buy a retail Tiger installer disc to use on the G5.

My simpletech external hard drive shows up in disk utility on one macbook pro but not my other one. how do i fix this???

I have two macbook pro computers. My external HD was reformatted on one of them from a PC to MAC. It shows up just fine on this macbook. The other macbook, I cannot find it. Ive tried in disk utility and Ive tried to see if it was hidden. Cannot access it. What can I do to make it show up?

Mac's with OS X 10.6.4 or earlier can't read exFAT, so if it was formatted with that (or OS X Extended J) ) and the other Mac is running 10.6.4 or earlier or is even older, it can't read the exFAT format or HFS+ format, perhaps only HFS.
You'll have to settlle for FAT32 (MSDOS) with a MBR Partiton map to be fully compatible with all computers, but you can't have over 4GB sized files with FAT32.
You can try OS X Extended, no journaled, just for the Mac's, but MBR with FAT32(MSDOS) would be preferred. PC and Mac of all types.
Before you change anything, remove all the data off the drive first.

Have you tried all the ports?
Have you tried with a different cable?
Have you tested all the ports with other devices to see that they are functioning?
Ciao.

Since I upgraded to 10.9.5, my macbook no longer recognizes my external hard drive. How do I fix this? External hard drive is a 1TB Toshiba formatted for mac. Worked fine until latest upgrade.

Solved the problem by dumping my external HD onto another computer. Re-formatting and re-installing the data. Not what I wanted to do but it solved the problem.
