Problems reading USB memory sticks with OS 10.9

Cannot read USB memory sticks with current version of OS 10.9.1 that I previously read without any problem. What gives? Any way to fix this problem? I have lots of work and other material saved on the memory sticks that I need access to this quarter.

Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.

Problems using USB memory sticks

Whenever i connect a memory stick with my macbook and try to delete a file off it, the file is moved to trash which is all well and good. But when i go to put anything back on it a message pops up saying that the memory is full.
Both times when i've encountered this problem i'd filled the memory stick with pictures and moved them onto a microsoft computer. Then i connected the memory stick back with my macbook and deleted all the photos from the stick by moving them to the trash can. When i go to put another load of pictures on it says its full. But there are no files on the stick!
Both times the USB memory stick can't be used, i've tried looking for any files on the microsoft computer but that can't find any or save anything to it.
Does anyone know anyway i can stop this problem and somehow get the memory stick to work again?

Hi
Try reformatting your memory stick using Applications/Utilities/Disk Utility. If you want to move files between OS X and Windows then you'll need to select FAT 32 format.
You may find you need to reformat the stick each time you copy a batch of photos from one machine to another.

Unable to read usb memory stick + "the disk you inserted was not readable by this computer"

Hi Everyone,
Today I was tryign to use a brand new memory stick 8GB-Samsung PNY on my Mac Book Pro. (Mac OSX 10.7.5)
1. I do not see this drive in the Finder.
   2. Diskutil could detect the drive.
   3. I was trying to put ubuntu image file on the drive from the terminal uitility and I have this error message in a dialog box:
      "the disk you inserted was not readable by this computer"
4. Clicking on initialize helps me realise that the drive is detected. But I do not have a clue on how to proceed from here. I am new to Mac and its file system formats.
The same issue happened with my 500GB external Western Digital Hard Drive. I was reading on forums that WD got some issues with Apple is trying to resolve. I expected to not have this road-block with another brand but it happened with my memory stick. Now I was forming an impression that something should be done to external storage devices inorder for me to use them Mac OSX.
Kindly enlighten me and help overcome this issue.
Thank You

Thank You OGELTHORPE.
I erased the memory stick and formatted to "Mac OS Extended(Journaled)".
I attempted once again to use the "sudo dd" command from termial trying to copy the Ubuntu image file to the memory stick.
The operation termainates with the same message
      "the disk you inserted was not readable by this computer"
The termainal message says some bytes got transffered in so many seconds. It looks like this operation is being terminated in the middle.
Have any suggestions and work arounds?

Size restrictions for USB memory sticks?

Hi out there,
are there any known size restrictions for the use of USB memory sticks with Mac OS X?
I bought two 32 GByte (noname) USB memory sticks to "mobilize" my iTunes-library. I formatted it without errors (believing what the DiskUtility-application told me) and copied my files to one stick. But only about 4 GByte of data where able to be opened after copying. The other files where shown in the directories with their correct sizes (I compared them to the originals on my harddisk) but couldn'd be opened.
I tried copying them a second time, using the second 32 GByte stick - but same behaviour as on stick one.
Next I tried to format both sticks with the DiskUtility using the option "writing zeros in seven runs" and then tested data integrity with the TechTool-Pro application (surface test, random read and write). Both showed no errors on the sticks. But copying my library again to the sticks showed no diffrent behaviour as before. The first few copied GByte (I think about 4 GByte) could be opened by iTunes, but the rest "is only there".
Any idea what's going wrong?

Hello Ansgar,
sounds like one of those faked 32GB Sticks.

Is there a problem with USB Memory Sticks and OSX?

This may not be the correct forum for this question but I don't know where else to ask!
I am having problems with a 64GB USB Memory Stick. Acrobat Reader can't read a pdf file on the memory stick but no problem from the hard drive. Acrobat Reader won't work from the memory stick. Music files (aif) won't play from the memory stick.
The memory stick came formatted for MS-DOS but I re-formatted it to MAC-OS Extended. I can write files to it but they don't seem to work from there. Is there some incompatability with OSX that I am not aware of? I would welcome some advice.

MAke sure the drive is inserted and mounted, then launch Terminal from /Applications/Utilities. Type:
mount
and hit Enter.
One of the lines returned will contain the words, "/Volumes/<name of your flash drive>". Copy that whole line and paste it here so we can see what's up.

Rescue and Recovery tool - problem with recovering files stored on USB memory stick

I recently had to use the Lenovo Care Rescue and Recovery tool to restore my 300 N200 to a previously backed up state.
As part of the Rescue and Recovery I selected the option to save user data in My Documents to a USB memory stick before restoring to the backup. This seemed to be successful (tool confirmed that 300MB of files were saved). But when I wanted to restore the files from the USB memory stick back to the laptop none of the folders/files is visible.
I checked the memory status of the USB memory stick and this confirms that 300MB space is taken up - but no files visible!!!
Can anyone help??

Usb memory sticks

Hi I have several 2 GB usb memory sticks. I use them to carry Keynote/Powerpoint presentations to different venues as backup. Recently I have noticed when transferring files from my new iMac that I keep getting the message that the memory is full on the memory stick despite moving lots of old presentations to trash. I don't understand this as it works with my iBook and my work windows laptop. It's a mystery. Can anybody shed any light on this?
Thanks Tim

Hi there

I have photos on a USB memory stick which I want to put onto my iPad. I bought the USB adaptor but for some reason the iPad is not recognising the memory stick. Can anyone help? Thank you

I have photos on a USB memory stick which I want to put onto my iPad. I bought the USB adaptor but for some reason the iPad is not recognising the memory stick. Can anyone help? Thank you

You need to create a DCIM directory off the root of the card, with the photos underneath it, and the photo filenames need to be exactly 8 characters long (no spaces) plus the file extension i.e. in a similar format as if a camera had created/written them. But a lot of USB memory sticks need more power than is supplied to the kit, so you may need a powered hub between it and kit.

When i download my pictures to a usb memory stick in jpeg format other computers cannot open them can someone help me to sort this please thanks from a new iMac user

when i download my pictures (in jpeg format) to a usb memory stick they cannot be opened on another computer ie not a mac, do i need to convert the file so that other computers can read it thanks Sam

Sam,
Format your stick with MS-DOS (FAT32) format. I use camera CF cards as memory stick and a good practice is to regularly format them: it deals with defragmentation effectively.
JPG is a standard, regardless of which application writes it and is readable by all applications supporting JPG.
Make sure you properly eject your usb stick when you take the it out of the usb port: it makes sure the OS closes all open files.

Formatting/erasing USB memory stick using Disk Utility - won't unmount

Hi,
I've got a 2GB USB memory stick, and I'm trying to format it by erasing it on Disk Utility just as I have done with many USB memory sticks before now.
Whatever I try to do with this one though I get the error message:
"Volume Erase failed with error:
Could not unmount disk."
There are no manual switches on the USB memory stick to change, and I've checked that I have read/write privileges so I don't know what else to do. I can't find anyway of unmounting it.
I need this memory stick for transferring a large amount of files and it's the only one I've got, so any help that would stop me from buying a new one would be great!
Thanks people.

sorry bro it's toast. the only time i had something like this happen the manufacture said the drive had to be re-flashed. if they provide the software online you got lucky. other wise they will tell you to send in and get it replaced (warranty valid)

RD 240 1046 11U won't boot if I have USB memory sticks plugged in to it, How do I get around this?

I have the boot order changed, so that it shouldn't even try to boot from the memory sticks, just the CD-ROM and the harddrive.
However, if I start up, the server just sits there with a flashing cursor until I shutdown.
If I remove the USB memory sticks, it boots fine. They are SanDisk 64GB sticks.
Is there another setting that needs to be changed, or is there a problem with the server?
Thanks!

Dear all,
your input on the following problem would be appreciated:
We have encountered a problem with both the "logout" and "timeout" functionality used in eCRM, due to the use of basic authentication.
Following a users logout and/or timeout period expiring, we are invalidating the user's session, so any user info will be removed from the server memory, and if the user attempts to access the site again there will be a security challenge.
But since basic authentication is being used and the browser already has your authentication information, it just sends it again transparently.
Whether users will notice will depend on how many windows they have open, and which browser they're using.
For example, in IE 5, if you open the secure site in a browser window, and close that window (using the close button on the logout confirmation page), it will "forget" the authentication information. But if I open other windows while connected to the secure site, it remembers the authentication info. Even if the users don't notice, there is a security issue associated with this behaviour.......
Any thoughts/ideas on getting around this problem (other than the obvious - not using basic authentication!!)Send HttpServletResponse.SC_UNAUTHORIZED (401) in the response header: http://www.tapsellferrier.co.uk/Servlets/FAQ/authentication.html has more info.

PM8M-V will not boot from USB memory stick

I'm using a PM8M-V mainboard and would like to boot from a USB memory stick (disk2go Pure T5, 256MB). The memory stick is bootable and properly formatted. The stick works fine with any other mainboard that I have tested so far. However, with the PM8M-V I cannot get it to work. (Other makes/models of memory sticks have been tested as well, but to no avail.)
Can anyone help?
I suspect that this is related to the fact that the PM8M-V BIOS does only support USB sticks as 'floppy drive', whereas on all other mobos I had to configure it as 'hard disk'.
Any help would be appreciated.
Best regards,
meter

Check in BIOS and see if the USB thumb drive is being recognised in the Boot Priority and whether you've select USB Device Support to "All Devices".

Virus damaging usb memory sticks

Hi, hope somebody can help me.
I got a virus on my usb memory stick from a pc and it got transfered to my macbook. Now I can`t use any usb devices on my mac as they all get the virus and the memory gets destroyed. The virus is now in my trash can (can´t delete it there) and I need help to get rid of it. It is a folder named "Recycler" with a folder inside named "S-1-6-21-2434476501-1644491937-600003330-1213". Inside are the files "autorunme.exe" and "Desktop.ini". Are there any programs that could possibly help me to delete it?

Welcome to Apple Discussions:
The "virus" in your Trash with the strange file name is sometimes referred to as a Windows Ghost and if so, you cannot delete it because it really is not there.
If it is not a Windows Ghost, you can delete it using the terminal
First enter
ls -al .Trash
and see if you see the errant file(s)
If so, then enter
cd .Trash
and then
ls -al
and you should see the same files, but now you are "in" the .Trash
if you see the files, then enter
rm -i *
and you will be asked for confirmation for each file before it is deleted. This is a security measure.
you may need to enter
sudo rm -i *
and then enter your password.
If this does not work, then the files are these sticky Windows ghost files and other means must be employed.
Are you running XP or Vista via BootCamp or Parallels etc.?

USB Memory Sticks for TM Backups?

Has anybody ever tried using a large USB memory stick as a nicely-portable Time-Machine backup drive?
In high-level concept it seems like it would be possible, but I seem to recall that a TM backup drive needs to be formatted in a certain particular way (MacOS Extended Journaled, as I recall), so perhaps not.

Flash drives simply don't have the capacity to function as a TM backup drive. Of course you can certainly use one but they are slow and small. They are useful to carry some data about but they are not intended to replace a hard drive. TM is not intended to maintain portable backups. Though it can be used in that way, it's not really designed for such a purpose.
Reasonably priced flash drives are available in capacities up to 16 GBs, but going above that is impractical both because of cost and lack of size over 32 GBs.
A full system backup requires at least 8 GBs of space. Since an 8 GB flash drive only formats to slightly less than 7.5 GBs, you would need to start with a 16 GB flash drive as a minimum.
