Acces denied for 1TB USB Disk in RHEL4

[Rohit Nagare]

Hi Good morning Friends,

I am using HP Workstation xw8400 Rhel4 Installed on it. I have connected 1TB USB hard disk. And made the single ext3 partion and mounted on a perticular folder. But when i copy a folder a file it get copy but after few minutes or hour when i copy a folder or file it gives the error as.

cp: cannot create regular file `/magma1tb': Read-only file system

As i have tried with chmod -R 777 /magma1tb
And chmod 777 /magma1tb

Any solution for this

Thanks in advance
Rohit

"Read-only file system" is not related to file/directory permissions nor chmod at all.

With default settings, RHEL switches a filesystem into read-only mode when it detects a hardware error.

You can verify the read-only mode using this command:
grep ro, /proc/mounts

You may try to switch the filesystem back to read-write mode with this command:

mount -o remount,rw /magma1tb

but if the system has detected filesystem errors, the command may be rejected.

In that case, you must unmount the filesystem, run a filesystem check on it, and then mount it again. (replace /dev/sdX1 with the real device name of the ext3 partition on your USB disk)

umount /magma1tb
fsck -C 0 /dev/sdX1
mount /dec/sdX1 /magma1tb

Also check the USB cable connections: a loose connector may cause random errors.
