Flash drive access issue.

[DrTeeth]

Had a previous USB flash drive formatted as ext2 and had no probs with it. Upgraded to a larger capacity drive, also ext2 and could not access it. I could read the contents of the drive but could not do anything else.

I had not problems with the smaller drive (16Gb). The larger one is (64Gb and USB 3).

As it seemed to be a permissions issue, will be trying FAT32.

Any ideas on what could be going on?

TIA

Try formatting to ext3 fs and see if problem persist

mkfs.ext3 /dev/sda1

if receive can't unmount error

umount /dev/sda1

Check your filesystem permissions. Make sure the disk is either world-readable, or at least root/admin readable.

I did see your advice on another thread after I posted. The thing is that I formatted both my USB sticks the same way and did not have to adjust the first drive's permissions in any way.

I am currently trying FAT32 on the larger drive. If the test works I may stick with it unless somebody can make a strong case for ext2. I do not need to store files > 4Gb.

Thanks

As the drive is a flash drive, I so not wish to use a journalling file system.

Thanks for the linux commands.

After an exhausive and exausting afternoon of tests, it looks like I was mistaken. There is a mounting issue, but it was a red herring. Sometimes a USB drive will just not mount.

The issue that was throwing me off is that suddenly, I cannot access the USB drive from my Win 7 machine like I used to earlier today until I swapped the USB drives. I really like being able to do this.

Error attached. I don't know how to fix this as I am not aware of anything having changed. Does one have to give each USB drive a different name? I can access the flash drive from a Linux machine. So it seems to be a Windows issue.
Asus N66U with 374.40 Merlin firmware.

UPDATE:- A Windows reboot fixed it - strange how it did not earlier today. A pox on you M$oft.
