Irregular flash drive mounting

Is there a USB equivalent to "SCSI Mounter" (from way back when) that lets you actively search for USB drives and mount them? I have an Adaptec Duoconnect Firewire+USB2 PCI card. I prefer to use this because of the USB2 capability. On occasion I have problems mounting flash drives with the card. I have two 1 GB flash drives, SanDisk Cruzer, and Imation. I have two cables plugged into two of the card's ports to allow me to plug in the drives from the front of the computer. Today after the computer had been asleep for a few hours I tried plugging in the drives after waking up the computer, and they would not mount (tried repeatedly plugging and unplugging). However, I plugged in one drive in the native USB port on the back of the computer and it did mount. I then tried the same drive in the cable and it still wouldn't mount. I restarted the computer and they both mounted in their cables. Sometimes the Imation drive won't mount in one of the cables but will in the other. After restarting today it would mount in the cable in which it usually won't. At first I wondered if it was a power supply issue, or cable resistance, but I changed nothing other than restarting the computer. As I said, this isn't the first time I have had problems with the Imation drive mounting, but I thought it might just be a problem with that drive on that cable (worn connectors). Now I'm thinking it is more a software issue. I can't say for sure if it's just a post-sleep thing, though I often leave my computer switched on 24/7 so I' usually using it in a post-sleep mode.
I don't see anything on Adaptec's website about Mac drivers so I don't think I can try that.

Actually, the drives are disconnected from the Mac when it goes to sleep (I already worked out that problem in another post). The real problem I had with leaving the drives plugged in was if I left the Imation drive plugged in and the computer went to sleep the computer would not wake again and I had to hard boot (restart button). I didn't seem to have this problem when I left the SanDisk drive plugged in, though of course the computer would give me a warning about the drive when I woke the computer.
This seems to be more a matter of maybe the card, or parts of it, not waking from sleep consistently. The card works with all drives in all ports when I first start up or reboot the computer. After it has been to sleep a few times the Imation drive has problems first. Last night was the first time I couldn't get either drive to work with the card until restarting, then both drives were recognized. I just started up my computer now and all drives work in all ports.

Finder stall after wake from sleep w/USB flash drive mounted

Has anyone else experienced this? iMac works flawlessly while USB flash drive is mounted UNTIL iMac sleeps. Then as soon as the iMac wakes from sleep the finder is non-responsive (perpetually spinning beach ball) and other apps slow to a crawl and become non-responsive as well if they need the finder (i.e. to save, etc.). This only happens when the USB flash drive is mounted.
Trying to force quit (relaunch) the Finder does not work, I always have to perform a hard restart.
I have an external FireWire hard drive that works beautifully and does not cause these same symptoms.
Any ideas?

umm.. don't let the computer go to sleep with your jump drive connected? The mac will usually take a few seconds to get his gear together after waking up from a sleep sounds like he is having to gather additional things since the jump drive is in there. I don't have a REAL solution except don't let Mr. Mac sleep with the jump inserted....

USB Flash drive mount on Mac 10.6.8 (Snow Leopard)

Hi, All my HP v250w cannot mount on my MacBook (OSX 10.6.8), i can see them on my USB (system info) but not in finder, so i can't read / write any data on them.
they function normally on my friend's Macbook Pro with Lion OS (10.7)
is there anyway i can make them function normally on my macbook?
Thanks in advance

Pharmineous, welcome to the forum.
According to the Specifications for the drive it should be plug 'n play with Mac OS 10.3 and above. Therefore, it should work without any problems with your Macbook. The key word is "should". Now, why doesn't it work for you. It may be that there is a conflict with other programs. Since it works with your friends Macbook Pro, it should work for you.
Was there software that came with the drive?
Signature:
HP TouchPad - 1.2 GHz; 1 GB memory; 32 GB storage; WebOS/CyanogenMod 11(Kit Kat)
HP 10 Plus; Android-Kit Kat; 1.0 GHz Allwinner A31 ARM Cortex A7 Quad Core Processor ; 2GB RAM Memory Long: 2 GB DDR3L SDRAM (1600MHz); 16GB disable eMMC 16GB v4.51

None of my usb flash drives are mounting

OS X 10.6.8 - None of my usb flash drives are mounting. They don't show up in disk utility either. System proflier does show the flash drives. I've run disk warrior and the flash drives show there as well. I've tried all of the usb outlets with several flash drives and none of them show up. I can use the same usb outlets to use my wireless keyboard, mouse and also my ipad.
Finders preferences are all checked to show items on desktop.
One of my flash drives I tried several times and finally got this screen message. "System extension cannot be used The system extension "/System/Library/Extension/IOStorageFamily.Kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update. Non of my other 6 flash drives mount and they do not receive any screen message.
I've also run repair disk permissions several times and the it says permissions repaired so I run it again and the same issued it said it was repaired, it lists again. I've done this several times with the same results.

Hello
from that
"System extension cannot be used The system extension "/System/Library/Extension/IOStorageFamily.Kext" was installed improperly and cannot be used"
try this
- boot from your original system disc
- plug one of your usb flash drives
- see if installer software could use usb flash drives as target for install
( testing your usb flash drive from a know good system software )
- DO not perform install on flash drive , just need to know if flash is usable
if it could , re-install your system or if it was updated from a previous version re-install 10.6.8 combo update

checking for any missing update ?

Can I have 2 flash drives?

I have an IMac from 2009. The OS is Mountain Lion latest version. I have a San Disk 32 GB Flash Drive which I used to backup my photos. The icon (SanDIsk Secure Access Manager) for the San Disk flash drive is all the way on the bottom of my desktop with the other icons. I am thinking of buying another San Disk flash drive - a 64 GB to backup my songs in ITunes. Will having 2 flash drives confuse my IMac and cause problems? Should I buy my second flash drive from a different company than San Disk so I don't confuse my IMac?

I'm talking about the actual Icon for the Flash Drive that is mounted on your Desktop and not the one for the Access Manager that is on your dock or wherever.
If your Flash Drive and Hard Drive Icons are not showing up on your Desktop like in my screenshot above? Click on your Desktop to bring Finder up on the Menu Bar, then select Finder / Preferences / General and make sure that the box for External disks is checked.
Close the Finder Preferences and then try changing the name of the Flash Drive mounted on your Desktop.

[Solved] unable to mount harddisk partition or flash drive

After recent updates to gnome 3.4.2,i am unable to mount harddisk partition or flash drive .I have 2 year old arch installation with gnome.
When i click on partitions in nautilus,it says "Unable to mount program files \n Not authorized to perform operation"
Problem is not only while mounting partitions.
Wherever we need authorization .Like changing date and time ,changing user accounts using gnome UI etc.The unlock button is greyed out permanently.
even i am not able to shutdown using gnome menus. it just log me out only ,do not restart or shutdown.Though i can shutdown using shutdown command on commandline.
i run gnome using daemon method. not through xinitrc .
https://bugs.archlinux.org/task/25031?p … ekit#close
I found a similar discussion in this bug. But since, i do not use xinitrc, it is unlikely they will help me.
Can someone be kind enough to help me on this?
Thanks in advance.

How to stop Windows from mounting a usb fat32 flash drive

Here's the problem. I have 4 identical Sandisk Cruiser 32GB flash drives. Windows has never mounted these drives in the past, until several months ago. Now Windows is mounting 2 of these drives but not the other 2. When the drives get mounted I end
up with about 5GB of files being added to each drive because they now show System Volume Information and the Recycle Bin. The amount of data added varies depending on the system I plug up to. On one Win 7 machine it can add up to 10+ GB. I would like to
be able to use the entire space for my backups but am unable to. These two drives are only used for Music and Videos. Is there a way to stop these two drives from being mounted in windows systems?
Thanks, Bill

Sorry but my figures are not exaggerated. Right now on this machine "System Volume Information" is showing as 3.2 GB and "Recycle Bin" is showing as 2.9 GB. I don't own these computers I use so I can't make changes to them such
as emptying the recycle bin. I only use portable applications from my flash drives on friends systems. By windows loading these two folders to my flash drives it it effectively stopping me from being able to use all the space.
Now as I mentioned in the first post, windows is only loading the SysVolInfo and recycle bin folders to 2 of the 4 drives. I am able to use ChkDsk on the two drives that are unaffected by windows but not on the other two. I get the message that windows
can't check the volume while it is in use and would I like to check it at startup. This always fails because, I think, These computers do not recognize the usb drives until windows is loaded. I have a work around for this in a utility that will unmount the
two drives and run ChkDsk and then remount them.
This doesn't answer the question though as to why all of a sudden this is happening to 2 of the 4 drives? And on several different machines? Windows does assign a drive letter to all 4 drives as it always has however the 2 drives without the system
folders are able to be scanned in windows without unmounting them.
I would really appreciate any insight into this behavior I could get.
Thanks, Bill

How to mount USB Flash Drive

Hello again Arch-Linux users,
I always search google very hard and for months (off and on) I search for how to mount a USB Flash Drive. Nothing ever work so I give up than try again months latter. I don't want to give up anymore and that is why I join this forum.
Here are some of the code I found on the net. Some of these commands will only re-mount the entire Arch-Linux running system in /mnt/usbstick.
sudo mount -o rw,noauto,async,user,umask=1000 /dev/sda1 /mnt/usbstick
... don't work it only re-mount the entire system
/dev/sda15 /mnt/usbstick vfat user,noauto,unhide 0 0
... don't work... I found nothing inside /mnt/usbstick
mount -t vfat -o rw,nosuid,nodev,quiet,shortname=mixed,uid=1001,gid=100,umask=077,iocharset=utf8 /dev/sda1 /mnt/usbstick
... don't work... here is the error i get:
mount: /dev/sda1 already mounted or /mnt/usbstick busy
mount: according to mtab, /dev/sda1 is mounted on /
It strange that most USB mount commands use the operating system partition itself- example: /dev/sda1 as the device for USB device, while others use /dev/cdrom for cd - /dev/dvd for dvd and /dev/fd0 for floppy.
Could someone post the code that will easily mount a usb device under Arch_Linux.
I'm using Arch-Linux core-64 (08-2009)
Thanks in advance

Thanks fsckd,
I needed a rapid reply because I been wasting too much time not getting anything done because I needed to get pass this flash-drive thing. I can now have a secure back-up in my pocket on USB to go. Arch-Linux does it better for what I seen while just dd'ing on disk.

Thanks demian,
sdb is the location for my single hard-drive machine. I saw it before in my list above but I changed it to sda1 because I knew no better. I had no clue it represent a 2nd hard-drive for LINUX if one is not already present.
This did it for me
Thanks again

Connection to server fail/Flash drive will not mount

I'm struggling with this issue and hope someone will have some insight these problems I'm having. I'm currently running 10.6.4 on my Mac and all of the sudden I'm unable to connect to my work's servers or mount a flash drive drive. The issue began after I corrected my disk permissions and restarted my computer. On the restart, I got a pop-up for each server I automatically connect to. The pop-up reads:
+*Connection Failed*+
+There was an error connecting to the server "SERVER NAME". Check the server name or IP address, and then try again.+
+If you are unable to resolve the problem contact your system administrator.+
At the same time, my flash drive, which has always worked, won't mount on my computer. But, here's the weird thing... I have two external drives connected to my Mac and they work perfectly. My only guess is that they're formated as Mac OS Extended (Journaled) and my flash drive is formated as MS-DOS(FAT).
Any ideas as to why these issues are happening? Thanks

Okay, this is just getting ridiculous. Turns out that my Mac will no longer mount a DVD. I'm working on a project in which I'm making a DVD with DVD Studio Pro and the disc burns just fine. However, when I insert to the disc to verify that it was burned correctly I cannot play the DVD.

10.5.1: Unable to mount a USB flash drive.

I've seen this problem posted elsewhere, but so far I have yet to see a solution:
After upgrading my MacBook Pro to 10.5.1, it can no longer mount USB flash drives. They show up in System Profiler as well as the USB Probe tool, but do not show up in Disk Utility (and, obviously, not on the Desktop or listed in /Volumes).
I checked the drives on a co-worker's MBP, also running 10.5, and the problem persisted there. The drives mount and work fine under 10.4, as well as various flavors of Windows. When plugged into the MBPs, the status LEDs light up, so they are getting power, and mice plugged into the USB ports work fine.
So, the problem seems to be specific to mounting a USB flash drive in 10.5/10.5.1. I'm not sure if this is specific to MacBook Pros, or if the issue is the same on all 10.5 machines.
Any help would be appreciated.

I have the USB problem. When I insert my USB memory pen, it flashes then stops. The icon doesn't come up on the Desktop, but the memory shows up on the System Profiler.
My USB telephone responds in Skype, but the sound input and output don't show up in Preferences, and so the phone doesn't work.
My Vodaphone USB internet modem won't connect.
This morning, I have no sound at all.
All these problems are resolved if the computer is restarted with the external source already plugged in, but it's a big hassle and must be solvable............

Flash Drive Won't Mount Except At Startup

Just bought a little 1Gb USB Flash drive which is USB 1.1 compatible. I want it for transferring files back and forth between my OS 10.4 G5 at home and the old blue and white G3 (OS 9.2.2) I have to use at work.
Trouble is, the G3 won't mount the drive unless it's inserted before startup. Apple System Profiler knows it's there when I put it in one of the USB slots on the back of the computer or in the spare slot on the Macally keyboard, but in neither case does it mount. I've looked at the USB events log in System Profiler and it registers the device being inserted and its call on the USB Mass Storage driver like this:
13436.785: [ 75579098]: Driver - Hub Driver - Device found, calling USBHubAddDevice. Port 3
13437.266: [ 75580125]: Expert - LoadClassDriver: USBCompositeDevice1.5.6 - calling driver initialize routine... 0
13437.267: [ 75580125]: Expert - LoadClassDriver: USBCompositeDevice1.5.6 - driver initialization completed 0
13437.578: [-1744497139]: Expert - LoadInterfaceDriver: USBMassStorageDriver - calling driver initialize routine... 0
13437.580: [-1744497139]: Expert - LoadInterfaceDriver: USBMassStorageDriver - driver initialization completed 0
So there's nothing there that says "fail" there unless that's what the zero at the end of each line means.
If I shut down the computer, insert the drive then start up, it shows up on the desktop no problem. It won't show up again if I trash and remove it though.
However, a graphite G4 in my office, which also runs OS 9.2.2 and seems to have an identical system install, will mount the drive with no problem on any of its USB ports.
Is this a case of the G3's USB ports being underpowered and there's no way round it, or is there a fix out there somewhere?
G3 Blue & White Mac OS 9.2.x

However, a graphite G4 in my office, which also runs OS 9.2.2 and seems to have an identical system install, will mount the drive with no problem on any of its USB ports.
Try this: Copy all of the extensions on the G4 that have USB in their names into the Extensions folder on the G3, replacing the USB extensions that are there; then restart and test again. Some of them may be older or newer versions than the ones on the G3 now, and that can make a difference. Note that in OS 9.x, it isn't always the newer versions of the USB extensions that work better.
Also see this user tip from Apple employee Joerg Weise. In it he lists 6 USB extensions (with version numbers) that can often resolve USB problems in OS 9, even under circumstances different from those described at the beginning of his comments.

Flash Drive Not Mounting

I just got a Swiss Memory swissbit flash drive that I attempted to completely erase and format in Disk Utility. I formatted as Mac OS X Standard and now my drive does not mount when I plug it in. The light on my flash drive blinks but I get no icon on the desktop or within the finder window. Disk Utility does not recognize it either for me to reformat and try again. Any suggestions?

I believe that could have happened. The drive
disappeared from the desktop after I selected "Erase"
in Disk Utility so I just removed it from the USB
port, as there was no way to eject it. Rebooting
gets me no where. However, the drive does show up
under USB in System Profiler as "Flash Disk".
Disk Utility will dismount a drive before it begins to format it. ( If it is mounted on the desktop, it is considered "in use" )
Once the format is complete, DU remounts the drive.
Of course, when dismounted, it will disappear. If you removed the device as soon as it went away, then the format process never completed, which would explain why it doesn't show up now.
Might want to check w/ the manufacturer to see if they have a reformatter utility for the drive.

Flash Drive not mounting, shows up in sys. prof. and USB Prober

I have a 4Gig Flash Drive that doesn't mount. It shows up in both SYstem Profiler and USB Prober. Is there any way to "fix" it? I don't need to recover any files - I just want to be able to use it.
It used to work, maybe a year ago. Havn't touched it since.
The port is just fine, it's definitely the drive.
Thanks for your time!

it doesn't show up in disk utility. unless there is a way to force mount it, disk utility can't help.

Mount a USB Flash Drive

I am running a 1998 iMac with a PowerPC Processor. It has MacOS 8.5.1. I have a PNY 2 GB USB Flash Drive. How do I mount this.

The link says it won't work with G3(which is what I have).
Where does it say that? Both the 8.6 update and the USB Mass Storage Support 1.3.5 are OK for a 1998 iMac (with 8.5.1 right now). Since the USB Mass Storage Support 1.3.5 requires 8.6, install that update first.
Oh, and I forgot to mention the only means of transporting data is through a CD(which I can burn).
Yes, you can transfer files on a CD. Use a CD-R (not CD-RW).
If you are using a PC for the downloads, make sure that the files are kept unaltered. Do not try to decode the MacBinary (.bin) on the PC. Once on the iMac, use an appropriate version of StuffIt Expander (which, hopefully, is there already) for the decoding (drag the .bin file onto the StuffIt Expander program icon). Otherwise, special software (such as TransMac) will be needed on the PC in order to correctly handle Mac files.
The iMac is not connected to the internet.
If necessary, that can be resolved within minutes. The iMac has a built-in modem for a dial-up connection, or it can be connected to a broadband router by means of an RJ-45 Ethernet cable.

Mounting flash drives in solaris failsafe mode

Hello all,
Suppose our system has crashed and we cannot login in solaris normal mod. But we need the data.
I have done the following exercises to take the back up of the file system.
1:- logged in fail safe mode.
2:- mounted the file system in to a mount point.
3:- took the backup of the file system using cpio command as /a/man.back.
4:- tried this command "mount -F pcfs /dev/c4t0d0p0:1 /a/flash" to mount the flash drive. But it failed.
How can we mount the flash drive in fail safe mode?
or, Is there any other way to take the backup of the file system to an external device to restore after re-installing the OS.
I would greatly appreciate it, if you could help me to rectify this problem.
Thank You
Regards,
Sajan.

Thanks, macbig...no joy yet, but definitely a helpful link.
I've confirmed via System Profiler on laptop #3 that my external USB drive is formatted as MS-DOS FAT32, so mount_msdos seems like the right utility to use. (The drive shows up there as /dev/disk1s1.) Meanwhile, "ls /dev/disk*" on the problem machine returns the following:
/dev/disk0 /dev/disk0s1 /dev/disk0s2 /dev/disk1 /dev/disk1s1 /dev/disk1s2 /dev/disk1s3 /dev/disk2 /dev/disk2s1
I've created /Volumes/rescue as a mount point and tried most of those devices with "/sbin/mount_msdos [device] /Volumes/rescue", with the following results:
/dev/disk1:
mount_msdos: Unsupported sector size (0)
/dev/disk1s1:
mount_msdos: Unsupported sector size (1)
/dev/disk1s2:
mount_msdos: /dev/disk1s2: Bad file descriptor
/dev/disk1s3:
mount_msdos: Unsupported sector size (0)
/dev/disk2:
mount_msdos: Unsupported sector size (64543)
/dev/disk2s1:
kextload: cannot resolve dependencies for kernel extension /System/Library/Extensions/msdosfs.kext
error loading extension /System/Library/Extensions/msdosfs.kext
mount_msdos: msdos filesystem is not available
Based on this, I'm guessing that disk2s1 is the device I want. Unfortunately, when I try to poke around in /System/Library/Extensions, I'm getting I/O errors...gah. I have a bad feeling about this.
