USB Drives (Fat formatted) mounting and size issues

Hello all,
Not really a major pain in the rear but rather a question as to whether anyone else has encountered this problem.
I have a kingston Data Traveler usb drive 256mb. When connected to my Intel mac mini dual core, and then disconnect it to copy drivers to an XP laptop. Upon reconnecting the drive to the mini, i find that it would not remount until i log out and then back in again. This does not happen all of the time however.
And the other issue...
When deleting anything from the drive the info states that the amount of space available is still the same as before the deletion. When you check the size of the .trashes icon it is around the same size as the files/folders deleted. This is the same even when dismounted and then remounted if it does.
If anyone has experienced these issues and found a solution, please let me know.
Many thanks

Can't beleive how stoopid i was for posting this problem. Just remove the trash when the stick is in. Duh

Connecting Time Machine USb drive to Time Capsule and continuing backups?

I've been backing up my iMac to an external HDD while I waited to get my TC replaced (blew the PSU about a month ago and I've been lazy about getting it fixed). Now that my replacement 500Gb TC has arrived, I'd like to continue with the current TM backup I have. Can I simply unplug the USb drive from the iMac and plug it into the USB port on the back of the TC? I know I can backup to the drive from scratch, but I want to be able to continue using the backup I already have. I know Time Machine over wired/wireless uses a sparsebundle instead and that a USb doesn't, so will there be an issue?
(And the reason I want to move the external in the first place is to free up some space on my desk)

You can probably do that, if there's enough room on the disk for two copies of your backups, or if you have a second disk you can use, but it's a bit tricky and will take a long time.
See #18 in the Frequently Asked Questions *User Tip,* also at the top of this forum.
If your current backups are case-ignorant, however, the procedure there won't work "as is". You'll have to either change the sparse bundle that Time Machine makes, or use a special Terminal command to copy your backups into the default sparse bundle.
So your best bet is probably to simply erase the drive and let TM start fresh. And if your USB drive doesn't have it's own power supply, you'll probably want to use a powered hub.

Yes, use Disk Utility in your Utilities folder.

SmartForms Character Formats, Fonts, and Sizes?

Does anyone have any good documentation, links, or suggestions related to character formats, fonts, and sizes we can use in SmartForms? My biggest challenges are trying to decide which fonts and their sizes to use in my windows.
For instance, what are good small, or medium, or large, font types to use under different scenarios, and what suggested sizes should be used with them? It would be nice to have some kind of a tip sheet that would refer to this. Because I spend more time playing with configuration then I do actually coding.
Open to all or any suggestions. Thank-You.

USB drive: what format for Linux and Mac?

I'm wondering what's the best format for an external USB harddrive to be used both on Macs (Tiger and Leopard) and Linux . I'm familiar with Linux, but not much with Mac.
I'd like to avoid vfat (the MS-DOS format) because symbolic links aren't allowed there.
Regards,
Ryo

Following up my own question, I've formatted the USB drive in hfsplus and it works both on Macs and on my Linux box (Debian testing).
One issue is that I had to turn off the journaling of the hfsplus filesystem, because (it seems) the Linux hfsplus driver doesn't support writing to the journaled hfsplus filesystem. The earliest discussion I found was from 2005 or 2006, and it's strange that the journaling support has still not been incorporated into the mainstream Linux kernels.
Without journaling, I have to be extra careful when I remove the drive. This minor annoyance aside, it works.
But, I'm still open to suggestions. For example, what's the situation of Mac OS X in supporting ext3 or reiserfs?
Cheers,
Ryo

Can't format cloned SSD that stopped booting in my MacBook Pro. Disk Utility always posts an error with mount and unmount issue. Any clues?

Is there any way I can reformat a cloned SSD that was used to upgrade my original HDD?
It suddenly stopped booting (a progress bar always appeared followed by a shutdown)
I've tried to reformat the SSD via USB case, and using Disk Utility, but it keeps on send error message with unmounting issues.
Any clues as how to overcome this problem?
Thx
Nuno

Have you connected that drive to another computer and if you have can you do anything with it on the other computer. If not then the drive has failed.

External USB drives will not mount under Mountain Lion

Since upgrading to Mountain Lion, two external USB2 drives that I have will not mount and cannot be viewed in the Finder. The same occurs on a 2012 MacBook Air, a 2009 iMac 27 and a 2010 MacMini, all running OS X Mountain Lion version 10.8.2.
Both drives are Samsung Story external USB drives (one is 1.5 GB and the other is 2 GB) and both have been formatted using Mac Disk Utility with a single Mac OS Extended (Journaled) partition, one using Snow Leopard and the other with Lion.
Both still mount correctly on a friends MacBook Pro that is still running Snow Leopard, and I had no problem with the same drives under Lion. Interestingly both can also be connected to Time Capsule USB port and show up correctly.
Both drives mount correctly under Windows 7 on BootCamp partitions that I have on both the 2012 MacBook Air, a 2009 iMac 27. These BootCamp partitions have Paragon HFS+ installed so I can read Mac formated drives.
Both drives show up in Disk Utility, but when attempt to mount the drives I get the message "The disk could not be mounted. Try running First Aid on the disk and retry mounting." I can run Repair in First Aid on the disk and get the message that the volume appears OK, but again have the same problem when I attempt to mount the disk.
I have also tried using Disk Utility 3,2, but still cannot mount the drives, though the program indicates there is no problem with the drives.
I have other portable USB including a Samsung portable USB2 drive, and two external USB3 drives, and I don't have problems with them.
There is clearly a problem with Mountain Lion with accessing (mounting) these Samsung Story USB drives, and the problem appears to be with Mountain Lion itself as the problem did not occur on the same Macs with Lion and does not occur with Bootcamp partitions on the machines.
I have a lot of time searching forums, but I have not found anyone with an identical problem.
I sure hope someone can help or that Apple come up with a fix for this issue which has only developed since the update to Mountain Lion.

Can i plug an usb drive into a iMac and access it with a Macbook pro?

I have an iMac that is less than 3 months old and my wife now has a two week old Macbook Pro.
IMac:
21.5" screen
3.1 quad core i7
16 GB Ram
1 TB Fusion drive
Macbook Pro:
13" screen
3.0 dual core i7
8 GB ram
512 GB Flash storage
Both have Mountain Lion.
Both are running iOS 6.1.2
I would like to attach an external USB hard drive to the iMac and allow the Macbook Pro to be able to have full access to just the external USB hard drive. Either it can't be done or I am just not getting the Sharing settings set correctly. I played around with sharing last night on both machines. When I would plug in a FAT 32 thumb drive into either machine and find it, I would add it to he shared folder but it would only allow me and "Everyone" to have access. I could not change "Everyone" to "No Access" because "Everyone" was greyed out or add my wife. I can access the Macbook Pro as Mark with the iMac but I can only access the iMac from the Macbook Pro as a "Guest".
I am using a Netgear WNR3500L router. I currently have the USB hard drive connected to the router via the Readyshare USB port but it is formatted as NTFS for Windows shared files. This router does not recognize HFS+ formatted hard drives in the USB port. When I move it to the iMac, I will back it up and then reformat it as HFS+. Since the router is about a year old and working fine, I would buy an Airport Extreme or Time Capsule if that is my only choice.
I don't normally turn off the iMac.
I would not want to allow access to any other device.
Since I am very new at Mac's, I would appreciate any help that any of you can offer me.

Topher Kessler,
Thanks for commenting to me.
My thumb drive is formatted as Fat 32 so your first paragraph explains what I am seeing.
You are correct that my existing router does not support HFS+. It is visible from my MAC and some file are read only.
The drive that I will be wanting to attach to the iMac would be formatted as HFS+ so it would not be accessible from my router.
So, if I setup sharing (If it is possible) and thern plugged in a USB 3.0 hard drive into my iMac, would it be accessible to my Macbook Pro? If it would not be, it looks like an Airport Extreme or a Time Capsule are my only options?
I see that a Netgear 4500 is Time Machine compatible. Any idea what that means? When I read pages 80 through 82, it appears to me that you format your drive to HFS+ and then eventually plug it into the router usb.

Thanks for your comments.

External USB drive won't mount after 10.9.5 upgrade

Is anyone else reporting the following issue? Immediately after installing OS X update 10.9.5 (13F34) on 09/18, my external USB drive (IOMega 1GB OS X Extended FS) used for Time Machine would no longer mount and isn't recognized. When I look at the drives in finder, it is missing. However, it does show up under the USB Hi-Speed Bus device tree:

I have reinstalled the combined 10.9.5 OS upgrade, and verified that the drive works when connected to my other MB Pro (mid-2012 running Yosemite beta 3). There is no third party software that I'm aware of in use for this drive, as it's only for Time Machine backups.
Thanks

Is the drive's icon on the desktop (perhaps behind another icon, which is possible if Finder > View > Cleanup is enabled)?
If not, is the box Finder > Preferences > General > External Disks checked?
Is the drive listed in every Finder window's sidebar?
If not, is the box Finder > Preferences > Sidebar > External Disks checked?
Are Time Machine backups to the drive happening on schedule?
If not, does the drive appear in System Preferences > Time Machine > Select Disk?
Can you open /Volumes/Mac-Mini 2/Backups.backupdb using Finder > Go > Go to Folder...?
Does the drive appear in Disk Utility? Is it (or can it be) mounted there?
Have you tried to plug it in to a USB port on the Mini (not a hub) or into a different USB port on the Mini?
Have you tried this: shut down; unplug the drive; boot the Mac; after you have logged in and the Finder is done populating the desktop and menu bar, plug the drive in?

Separate /var resiserfs partition on usb drive won't mount on boot

It has mounted successfully a few times. I set it up because I don't want /var on my Revodrive, and I've added a label (var) to the partition. I've tried mounting at first by UUID, then label, then strictly by dev (which isn't an option considering the number of block devices I have attached at any given time).
I have to manually mount var afterward, and this causes all sorts of hal problems with KDE, such as not being able to see my hard drives in Dolphin.
Any ideas? I have another mechanical HDD that I'm going to be using as a download drive, so I could locate var there if needed.
Here is my daemons array in rc.con:

I think it is needed to be able to boot from a usb disk. (You'll have to run "mkinitcpio -p kernel26" afterwards.)
That makes sense. I actually prefer using the sata drive as /var, but I was just interested as to why it wasn't mounting.
BTW I have GRUB and boot installed on the same USB drive (from which I boot), then it mounts the root and home partitions on my OCZ Revodrive. This drive is essentially fakeraid with an sil satalink controller, and I was never able to get grub installed on the dmraid setup. I just gave up. It actually works quite well though.

External USB drive won't mount without running Repair Disk

I have a Seagate external USB hard drive. It's a 1TB FreeAgent drive that's USB powered. I use this to share data across several computers. Every time I connect the drive to my MacBook Pro, it does not mount. If I try to mount it, I'm told to "try running first aid".
So, I run repair disk, and then it will mount. I just did this, and Repair Disk reported "The volume /dev/disk1s1 appears to be OK".
Any help on this matter would be appreciated. It is formated NTFS, and I have an NTFS driver installed, if that makes any difference.
Thank you!

USB drive cannot format

So I just bought an 8gb usb drive, and after bootcamp assistant failed to copy my windows iso to it, I was forced to eject it. Now all format and erase options in disk utility are greyed out. I've tried formatting it in windows and no luck. Windows tells me it's write only. I've tried every fix I can find (boot from safe mode w/ command prompt, regedit, diskutil in terminal) and NONE have worked. Right now terminal is telling me that the usb is read only, has no file system, and no mount point. PLEASE HELP!

In Disk Utility (/Applictions/Utilities/Disk Utility.app), can you partition the USB drive?
Open Disk Utility in the Utilities folder.
Select your USB drive from the list on the right. It should not have any indentation (which is for the volumes on the drive).
Select "Partition" from the tabs.
Change "Partition Layout" to "1 Partition".
Give the partition a name and format.
Click "Apply".
Important note: Be careful to select the correct disk as partitioning a disk will erase any data stored on the disk. I advise that you disconnect all other external drives from your computer (except the one you want to reformat) so you do not accidently erase the wrong drive.

USB drives compatible with MAC and Win

Can anyone help me out. I need to encrypt my USB drive but such that it can be decrypted by both my Mac and a Windows machine.
1) If I encrypt the USB drive using the MAC to create an encrypted disk image, will the Windows machine be able to access this disk image?
2) Is there a decent USB drive on the market with encryption software compatible with both Mac and Windows machines?
Thanks for any help (and excuse my Mac ignorance !)

I have the same issue and ended up damaging my USB when Sandisk tried to format it so it can be used for MAC. Its very frustrating that all these big companies can't make MAC compatible software. What's more frustrating is that they advertise their product saying it works with WINDOWS n MAC but when you go check out the encryption software then its only windows compatible.

USB drives don't mount

I have a problem with my brand new macbook. When connecting usb thumb drive or external usb hard drive to the computer nothing happens. There isn't disk image on the desktop or in the finder sidebar. The drive doesn't show on disk utility.
With thumb drive there isn't any system messages at /var/log/system.log or any events with dmesg.
With the external usb drive there is following message at /var/log/system.log
USBF: 29698.842 AppleUSBEHCI[0x557e800]::Found a transaction past the completion deadline on bus 253, timing out!
How ever, if I connect usb universal card reader to my macbook and insert memory card from my digital camera is is recognised. So the port is functioning fine with that.
What should I do to get the system working with my usb drives?
I've updated my system to the latest with software update.
murkus

Hi Murkus,
try to reset your PRAM to "refresh" your usb port.
Check the thumbdrive and external HD web site for firmware updater / patch on their sites.
And if you have power adapter for the external. try to use that too, or use Y usb cable to connect both end on one side to macbook to get more power and the other single end to your external.
Also try to leave those connected and restart your macbook, hopefully it will mount during start up process.
Good Luck.

All USB drives disconnect after upgrade and clean install of MAC OS X Mavericks

I first upgraded to Mavericks and noticed that my external USB dries would disconnect after MBP Retina Mid 2012 model was updated to Mavericks. These worked fine in all versions of Mac OS X before upgrade. So I did a clean install figured my machine would benifit from this anyway. This did NOT fix the problem.
Wouldn't be much of an issue but I use this macine as a media server with Plex and all the media is in one of the external USB 3.0 drives. All drives are from Seagate, and have found no info there. Guessing this is a bug that Apple needs to fix unless its a Seagate issue which I doubt.
My TEMP FIX while my machine is plugged in to the power adapter and drives.

If the tracks are recognized by your iPod (playable), search VersionTracker for "iPod". You'll find a number of utilities that can transfer your tracks and your playlists from your iPod back to your Mac.
If they're just on your iPod as data, then I'm not certain since I don't use a custom hierarchy, but you should be able to copy the folder back to your iTunes Music folder, turn off the "copy to iTunes library when adding to library" preference, and then use the Add To LIbrary command to get them recognized by iTunes. Again, though, I don't use a custom hierarchy, so you might want to ask that question as a new post, just to get additional opinions.
BTW, an iPod is not a reliable backup for your tracks. Too many situations can arise that would cause your iPod to need to be erased. I strongly recommend that you make backups, particularly of any tracks purchased from the iTunes Music Store or that would otherwise be difficult to replace, to CD, DVD, external hard drive, or other medium.
