OS X :: Can't Format Flash Drive - POSIX Error
Sep 25, 2009
I've done this many times before, and I think it's just a failing drive, but I wanted to check and see if anyone had successfully worked around this problem before. I have a 16GB Transcend flash drive, and it stopped working last week. When I connect it to a computer, I get the message that I have inserted a disk that cannot be recognized. Disk Utility only recognizes the device, but no volumes (see attachment #2). When I try to format it, I get an error that says it Can't allocate memory (see attachment #1).
Anyone recognize this? I can send it back and get the drive replaced under warranty, just wanted to see if there were any other thoughts.

I was trying to back up my MacBook to a WD 1TB external drive. It has already been used on my wife's iMac running OSX Tiger. It has had no problems. When I plugged it into my MacBook, it started freaking out immediately, and slowly creating folder after folder on my desktop. Eventually I had 46 folders that were all named the name of the hard drive. I tried to repair disk, and erase disk and partition the disk - but none of them would work. With partitioning, I get the error message: Partition failed with error: POSIX report directory does not exist.

I was recently gifted an 8gig Transcend Flash Drive by a friend. When I inserted the drive into my unibody MacBook Pro running Snow Leopard, it pops up a window that says:
The disk you inserted was not readable by thing computer
Initialize / Ignore / Eject
Clicking on Initialize takes me to Disk utility and if I try to format the drive. it gives me an error that says:
Partition failed - POSIX reports: Cannot allocate memory.
I then take the drive to a Mac that's running Leopard, but the same thing happens there as well, except the error when formatting tells me it's an 'Input / Output error'
On both the Macs, I've tried formatting with a GUID and MBR, but neither works. I've tried to format it as Free Space/MS-DOS format or even the native Mac OS Extended, but nothing works.
--
Now, before you come to the conclusion that it may be a faulty thumb drive, I need to tell you that the drive works perfectly fine on a PC. I've tried it on 3 different PCs, running XP, 7 and Ubuntu respectively. All the tree are capable of detecting, mounting the drive and read/write it just fine. I could even format the drive just fine on all three computers.
What's more, I installed Mac Drive on a XP machine and it could format the drive as HFS+ too.
This thing is driving me nuts for the past 12 hours and I'm out of solutions what to do.

I work for a post secondary school with online formatted classes. We send flash drives out to students to access video content when they are on the go, but it was pretty much made for Windows based computers. I have had a few students now who have Macs and cannot open the content or are getting a message stating the drive is not formated. I see many instructions on how to format a flash drive from a Mac to work on a Mac & PC but nothing about being able to format the flash drive using a PC so it can work on a Mac.
Info:
Dell, Windows XP Pro, Windows 7

When attempting to use the Software Update, I get the following message: "POSIX Error - Cannot allocate memory." Also, when attempting to access Safari, the following message is displayed:Other suggestions previously have not worked, such as Preferences, Disk Warrior, etc.Are there any others that may be recent or ground breaking? Is it possible that Tiger is simply at the end of its lifecycle?

I have a G4 1.25 Dual Power PC and I've added a 320Gb ATA drive as the system drive. All seems fine except that in Disk Utility the drive appears RED and it says ' This drive has reported a fatal hardware error to Disk Utility" It won't let me format the drive or First aid it etc.
Anyone know how I can do a low level format and maybe try and locate the damage?
I've tried Disk Warrior and Tech Tool4 to no avail.

I received an Acomdata 2Tb external hard drive today from Amazon and plugged it in. Time Machine popped up and I declined to link the hard drive to it. I went into Disk Utility and chose the new hard drive on the left column and went to erase. I chose Mac OS Extended. I named it and hit erase. It started going, and going..... and going... and a half an hour later I knew something was wrong.
Disk Utility was not responding and I eventually had to Force Quit. Now I cannot format the hard drive. I starts and then it stops with a disk error. I tried to run the First Aid verify and repair and both stopped after a few seconds with an error. What do I do?

The problem is when I put my 4gb flash drive in, the computer doesn't recognize it and doesn't show up on the desktop. So I go into Disk Utility and try to format it to maybe fix it that way, but when I try to, it says format failed, permission denied.

The message is saying "operation cannot be completed because an item already exists with that name." They are brand new therefore not the same name? I cannot even put them in a brand new folder..

I'm running Snow Leopard on my new Macbook Pro. I've got a 1.5TB External hard drive that I'm trying to figure out how to format in HFS+ with Apple Partition Map. I can figure out how to format in HFS using Disk Utility, however it still does it in GUID format and I do not know how to do it in Apple Partition Map.
Googleing this for hours has lead with all kinds of information on how to go to GUID FROM Apple Partition Map but not the other way around. I know GUID is the new hottness.. but this drive will be used exclusively to connect to my XBOX 360 and it supposedly only reads HFS+ when its formatted with Apple Partition Map. (I have tried it with Mac OS Extended (Journaled) with GUID, and the XBOX does NOT recognize it) I do not want to use Fat 32, (I know that that is the other major option) beacuse it limits file size.

I think at one point (probably when I switched from my 80GB to my 500GB drive) I screwed up and made the partition format on my drive Apple Partition Format. As I was just doing disk cloning, Leopard had no problem with this, and never mentioned anything being wrong (if it did I could have fixed it back then). However now, when I try to upgrade to Snow Leopard, it complains about this, telling me I can't upgrade and my only real option is to back up my data and fresh install. Problem being, I don't have a 500GB drive laying around, and I don't have the money to buy a 500GB drive to use once to back up all my data. It pisses me off to no end that Leopard didn't complain about this when I first did it if it was going to be a problem in the future (back when I could have fixed it) and only now it's become a problem. I guess my question is, is there any way I can get by this problem and install Snow Leopard? Or am I gonna have to wait till my friend needs to wipe his PC again and borrow his HD for a night?

I'm trying to convert some rmvbs to avis using ffmpegX and no data file with other formats but as soon as I drag it in, ff freezes. The first file has a size of 92MB. If this is not going to work, please tell me a free converter that will convert them. Or at least one which has a trial version NOT a demo version.

I am doing tech support for a family member, He is running OS X Mavericks 10.9.4 on a late-2009 27" iMac, and Time Machine is/was set up on a 2TB LaCie d2 Quadra V3 connected through FW800. He had noticed that Time Machine had not run in a while, so I opened it, and his former Time Machine drive could not be found. It wasn't showing up on the Desktop or in Finder, so I opened Disk Utility to see that it is unmounted. When I tried to mount it, it did nothing. I verified the LaCie drive and it returned no errors. I verified the disk, and it failed and returned "Underlying error: 8: POSIX reports: Exec format error". I tried to repair the disk and it returned the same thing. I am not sure if it has been working since he upgraded to Mavericks. It seems to me that the drive is dead, pre-reformat, but let me know if not. (I am not sure why it would have failed. He doesn't seem to turn off his computer, and I doubt he has unplugged the drive at any point. It may have been running for several years straight, though.) If it's dead, is the data likely recoverable?

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.

I had windows vista installed but suddenly the audio decided to become faulty, after spending a day trying to fix it i realized I have a windows 7 install disc so i might as well just replace vista with windows 7. I didnt take care of vista or ever register it so it became quite a task to upgrade so i just deleted the partition and went to create a new one and just do a full install of windows 7.
I made the partition but the wrong format, so i removed it through boot camp assistant and created another, except now it keeps giving me the "back up the disk and use disk utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using boot camp assistant again" Now, I'd love to do this, except I have no idea what I'm doing and WHY this error has occured. After becoming frustrated I switched from my imac to my macbook pro and received the same error when trying to create a partition. So any help on exactly what I need to do would be a HUGE help. I only use windows for music production (I know, seems backwards, but I use Sony Acid and FL Studio so I'm stuck with Windows)

I have a Seagate external hard drive that just stopped working one day (made a lot of clicks then disappeared from my laptop's desktop). When I plug it in to my PC or my Mac, it just makes the clicking sound and then nothing happens.

I am having a huge dilemma with my new Western Digital 4TB Hard Drive. It came formatted for Mac OS and I need to format it under NTFS. The problem is Windows will not format it, I always get an error message. I have tried two different machines. The major issue is that I cannot format it to FAT32 first before formatting it under NTFS bc the drive is larger than 2TB. My media player will not recognize Apple's format...
