ExFat Flash Drive Read Only

I tested it with my own MacBook and got the same status. I took it down to my neighbor who has a MacBook Pro and got the same results there.

All systems recognize it under Disk Utility and report it as being formatted as ExFAT and "NO" to Owner Enabled - whereas all the other drives on my system report Mac OS Extended (Journaled) and YES to Owner Enabled

I don't know who formatted it as ExFAT although I see it as an option on both of my systems. I was sure I formatted it as OS Extended Journaled when I passed it on to my friend but the drive says it is ExFAT. He swears he didn't touch the formatting and did not let anyone else use the drive. If I had formatted as ExFat then it should report it as Owner Enabled.

I'm stumped. There should be a way to remove the read only status to free up the drive for reformatting.

I'm only as positive as it is reported in Disk Drive which says it is ExFAT. When I check the available format methods for all my other drives I have the option to format with the Windows NT Filesystem but when I try and look at the formatting options under the Flash Drive, which fall under the Erase tab, I am stymied because Erase, RAID and Restore are greyed out. Under First Aid I do have the option to Verify the drive but not Repair or verify/repair Permissions.

When I Verify the drive the response is "The volume Flash Drive 65G appears to be OK."

It applies to both the drive and the partition (volume). The only difference is on the drive I cannot verify the drive where I can verify the volume.

I do have Crossover installed and downloaded a Windows disk utility (three actually), installed them but they only recognized two disks, both at 76G but they don't see or report the flash drive. BTW, I have no internal or external drive smaller than 2 and 3G in size so the utility is not seeing anything beyond 76G on drive 1 and 2.

Ok. As you can see the erase options are greyed out on the drive itself.

Sorry, here's the partition screen. Again, I can see the Cary volume but the options to resize are greyed out.

Ok. Looks like I lost the attention of "nbar". Can anyone else suggest a resolution?

I don't know anyone who uses Windows and took it to a Coffee House to ask if someone there would reformat it for me. Most of the time I got a 'no' fearing it may harm their systems (???) and those willing to had no idea how to perform a reformat. I figured it couldn't be that difficult on a Windows machine, there must be a disk utility somewhere on the system, but they wouldn't let me look or even try.

I did contact the manufacturer and was told the drive should work under OS X but they have never tested it and would not allow me to return it because the purchase date was beyond the 60-day warranty. I did tell them that I would alert the Mac community about the problem and suggest Mac users avoid PNY flash drives or other drives.

Because it was a 64G flash drive I paid a handsome price for it from Staples. I returned it to Staples and asked for my money back but again, according to my receipt, it was beyond their warranty period. Of course, they took me to the locked flash drive cabinet and suggested I purchase another brand but I was ticked and promised I would not buy another item from them.

I've asked the (former) friend who borrowed it to replace it with a different brand and mailed it to him because it contains all of his files. He has not responded thus far and I doubt that he ever will. Its too bad. I'll never loan another Flash Drive to anyone again, good friend or not.

Could not get Unibeast to install on an 8G flash drive using a Mavericks Mac. I'm left with a 65G flash drive that is formatted for ExFat and read-only that cannot and will not be erased and reformatted for OS X. Arghhh! Don't know why Unibeast won't install on an 8G Flash, too small? Or is it that Unibeast can only be installed using a Windows system? All options are greyed out when using the Disk Utility on the 65G flash drive.
