MacBook Pro :: Doesn't Detect USB Flash Drive
Jan 14, 2009
I have a Macbook pro (OSX 10.4.11) and all of a sudden it stopped detecting a fairly new Jump/Flash drive that up until now worked fine. The icon doesn't show up on the desktop or in the Macintosh HD window.
The flash drive has "Dane-Elec" printed on it and is 4GB. I've tried it a number of times and nothing. The drive does still work on other computers, and my usb port is working properly with other devices.
The flash drive doesn't seem to show up in System Profiler and my Disk Utility has been "gathering information" for about 5 minutes now." Everything else is working fine with the notebook.

For some reason, when I try to delete files from my flash drive, the file disappears but I don't get any space back on the flash drive. This is ruining my 32 GB flash drive.

I just got a new flash drive and it worked fine on my iMac yesterday, and now suddenly it no longer appears on the Desktop or anywhere else on the computer that I can find. But when I pulled it out of the USB drive, it said the device was not removed properly, so it must have recognized something was connected.

I have bought Macbook Pro last year. Its 2.4 Ghz Intel Core i5 machine with 4GB 1333 MHz DDR3. Of late it used to go to sleep randomly even while working. Last week I took it to Apple store who was not able to diagnose the cause of the problem but as a precautionary measure has changed, as per him, a bus connecting harddrive to the logic board. However the problem was still not solved. Few hours ago suddenly the machine went off and on starting it I found that it is not detecting the batteries. On the battery icon it displays an X, states "no batteries are available" and randomly switches the power source from battery to adapter and back. There is no light on the adapter. [code]

I bought a MBA 13" last month and now I'm trying to connect an external monitor through a Mini Display Port-to-HDMI adapter and most of the times the display shows a message "No signal detected"...
I've tried all the possible combinations between the MAC and the Monitor but it would seem a random matter.

I have a flashdrive that I have used without issue before, but now my imac doesn't "see" it. It works on my macbook just fine. I have investigated the issue by checking DU, but it doesn't show up there, either. I have OSX 10.6.3 on the imac and OSX 10.6.2 on the laptop.

I just upgraded my daughter from last year's MacBook to a new 2009 MacBook Pro (my mother will get her old one) by cloning the drive using SuperDuper. Everything works fine except it doesn't detect the audio hardware in the OS. I see that the new macbook pro has different audio hardware according to system profiler. Is there a way to copy the driver off the install DVD or should I just go ahead and reinstall everything.

I have a macbook pro (penryn) that just stopped working. I believe the hard drive just died on me because whenever I try to boot up, I just hear this clicking sound. I think I may have a bootable backup I made with SuperDuper! a while back on my external hard drive. I tried connecting it to my MBP but it wouldn't detect the drive. I only get the mouse cursor when I hold down the option key at boot.
Does anyone know if this may be a known defect? Do you think Apple will replace the hard drive for me?

I recently bought an SSD vertex 64gb for only 200$ cad. Unfortunately, I do not have enough space to install the Soundtrack Pro components on this drive. I recently bought too an eSata powered cable and a express card esata who came with it. The hard drive can't be detect on my macbook pro unibody late 2008 2,4" but runs. I install the silicon image drivers non-SL and adding over that the SL drivers.
[URL] In that case, I want to know how to uninstall those drivers from silicon image 3132? I thought about another thing if it really not work eventually. The dvd-drive bay could be remplaced by an enclosure 2.5" for my factory 250gb 5400rpm.

Second question, Does this other hard drive will take a lot more power?

Just installed a new HDD into a macbook pro that was dropped. Seems fine, loads the disk and then says it can install the OS, i load up disk utility and theres no hard drive int he list just the optical drive and the DVD, its not the disk that came with the mac itself its either my proper retail one or the one that came with my personal older macbook which might be the issue. Ive taken apart and reconnected the HDD and all seems fine internally. Are there any issues that cause this except not using a full retail disk which im going to try later on, just wanted to rule everything else out.

transfer my files from my WD external drive to my MBP but to no avail. I installed them both and after that, my WD Elements wont show anymore. It was working before prior to installing MacFuse & NTFS-3G. So I tried to remove them both but still the same problem. It wont detect my WD external drive anymore. The light on my WD drive is lighted up as usual but can't be found on Finder. I also tried to remove the WD external drive from my MBP and it recognises that my WD is there! Its says did not unmount correctly, something like that. I also tried to isolate the problem using another computer, this time, Windows and it works well.
The Culprit of all this is when I install MacFue & NTFS-3G

I installed NTFS for Mac to read/write external hard disks that I shared between my Macs and PCs. It's doing find until recently after I upgrade my MacBook to Mac OS Lion.
It can still can detect certain external Hard Disk, but still cannot detect some external Hard Disk and Flash Drive even though it is supposed to be dual formatted.

I have a MacBook Pro running OSX 10.7.2 and it recently stopped booting. Got the gray screen with the folder that has the question mark on it. I have attempted to use Command + R to do a Internet Recovery of the system, but once I get to the Mac OS X Lion screen to select where i want to install OSX, there are no hard drives listed.
So I figure, the hard drive (Hitachi 500GB that came with the Mac) is damaged or not functioning correctly. This doesn't seem to be the case because I can hook it up to a notebook SATA hard drive enclosure, connect it to my other MBP and read all the contents of the drive! This was good news, as i was able to copy off all important data, etc.
Using Disc utility, the partitions check out, and the drive appears to be functioning OK.

Checking file systemChecking Journaled HFS Plus volume.
Checking extents overflow file.

Checking multi-linked files.

Checking extended attributes file.
Checking volume bitmap.
Checking volume information.
The volume Macintosh HD appears to be OK.
Volume repair complete.Updating boot support partitions for the volume as required.
I have purchased a replacement hard drive and am waiting for it to arrive in the mail.
My question now is this:
Am I able to do some kind of time machine backup, make an image, or do some kind of target drive restore from this hard drive since it is accessible on my other computer?
I don't mind reloading the operating system on the original MBP, but would really like to avoid the process of setting up all the applications, settings, etc if this drive is in fact functional.

My friend's MacBook Air crashed. It blacked out, and turned off. Now, when he presses the power button, he gets a beep, and that's it. the white LED light also doesn't flash. It's a short, soft beep.

when I go to a YouTube video, it will just be a big black rectangle (see pics) with no slider or anything, and nothing happens when I mouse over it. This happens to all videos on websites (see the BestSkinsEver, there's supposed to be the Gizmodo iP4 leak where there's just a big white space). I was curious to see if this happens to flash games too, which it does. All the pages were fully loaded when I took a screenshot.

I recently just purchased a macbook pro and am trying to convert files from my external hardrive on to my mac. My external was used with my old computer which was a dell so it was run off of windows format. I cannot afford to lose all of this information i have on here. Is there anyway i can convert these files so my MAC will read them without having to delete my files on my external.
I connect my external to my MAC and it says it doesn't read it, i believe it is in ms-dos format.

When I travel I would generally take a small travel drive that is clone of my white MacBook as a rescue drive.Now that I have the MBA I am wondering if I could just clone my 11.6 MBA to a 64 GB flash drive and then if the worst happened I could reverse clone from the flash drive to the MBA.

When I go to certain websites that use Adobe Flash Player with Firefox 3 in one user account, the Flash doesn't work. Some Flash websites do work, such as Youtube. What in the world is going wrong? How can I fix it?
The details:
I have a MacBook Pro running OS X 10.5.6, it has two user accounts. One user account is mine, has administrator privileges, and gets most of the use. The other user account was created later, lacks administrator privileges, and gets little use. Both user accounts have Safari and the latest Firefox 3 (3.0.8) installed. The problem with Flash occurs ONLY in the second (non-admin) user account, ONLY in Firefox, and ONLY on certain websites.
Websites with Flash that do work:
1. YouTube.com
2. Every website I could think of with a simple Flash intro
Websites with Flash that DON'T work:
1. pandora.com //The HTML loads fine, but there is a dead white box where the Flash UI should be
2. Macromedia Flash settings manager //There is a medium white box where the Flash UI that allows you to change settings should be.
3. seeqpod.com //Very odd failure mode: The Flash UI loads, and works. I click "sign in", and the "sign in" dialog appears. I type my username and password and click enter, and then the whole Flash UI freezes forever (well, for at least 30 minutes). This crash is unrecoverable.
Note that all three of those broken websites do work in Safari in the non-admin user, and all three of those broken websites do work in both Safari and Firefox in the Admin user.
What I have tried:
1. Upgrading from Flash 9 to the latest Flash 10. No change whatsoever.
2. Uninstalling all versions of Flash using the Flash Uninstaller for OS X 10.3 and up, available from Adobe/Macromedia, then reinstalling Flash 10. No change whatsoever.

Tried zapping PRAM and resetting SMC. 3 different cards, 3 different readers with same non-read. Same readers are OK with SD. All 3 readers with all 3 cards read ok on PC. 1 out of 10 times Disk Util sees it, but can't repair. Tried to reformat with Disk Util - 'can't write last block'.

I have a recent (3 month old) 13 inch MBP with the 512GB SSD. I'm considering a 13 inch MBA with the 256GB NAND flash drive. Obviously I'll have to manage with less storage space, but apart from that, what is the difference between the two drives? Will the newer one in the Air be faster, as it is an Apple custom component rather than an off the shelf part?
I think the new Air is great value, BTW. The SSD in my MBP cost a fortune (but it is really really fast). Also, before anyone says "just keep the MBP", my assistant wants one, so I'll be buying either another MBP or a MBA anyway.
So which is faster MBP with standard 512GB SSD or new MBA with standard 256GB NAND flash?

My PNY attache hook 16gb flash drive was working for about 2 hours with my macbook, but I ran into a problem with itunes and was forced to restart my macbook pro. The usb was only plugged in, no files on it, none in transfer. After the restart I pluged the usb back in and it no longer shows up, I tried using "diskutil list" in terminal and it didn't show up. I have tried all the usb ports on my macbook and it still does not show. Did I somehow corrupt the drive so much that it doesn't even register in terminal? Should I try to get a refund? Or, can I fix this some way on a software/firmare level?
