I have a 16GB Toshiba USB flash drive that stopped functioning correctly after an interrupted file transfer (took it out while it was transferring files on a Windows machine).
Windows recognizes the drive, but only after I wait a minute for it to load it up. Plugging it into my MacBook Pro, it is also recognized, and I see the files on it. However, I cannot move/delete any of the files.
I don’t care about the files on it, and tried to do a DiskUtility reformat on my Mac.
This is the error I get:
Error: -69760: Unable to write to the last block of the device
Any ideas? Running the command:
sudo dd if=/dev/zero of=/dev/rdisk2 bs=16k
as I’ve seen on some threads returns this:
dd: /dev/rdisk2: Device not configured
1+0 records in
0+0 records out
0 bytes transferred in 16.732716 secs (0 bytes/sec)
The drive is currently formatted in NTFS.
EDIT: Worth mentioning that if I right click the drive on 'My Computer' in Windows, and press 'format', nothing pops up... perhaps I have to wait a long time, currently trying this.
EDIT: Turns out that Windows sees the drives as having 0 bytes on it, and a capacity of 0 bytes, and the drive is 'unreachable'.
/dev/rdisk2
the same device name used when you can get the Mac to read this flash drive?
