How read the external Hard disk in right size?
Dears,,
I connected external Hard disk to Linux PC. but the external hard disk appears in a wrong size. Also, i tried to copy from the PC Hard to the external hard it gave me error that there is no space although that the both hard disks are the same mount points and size. Thanks & Regards,, |
What distro are you running?
What formats/file systems are the disks? run df -h and post the results |
Kindly , see the following . . .

So where/which disks are you trying to copy from/to?
What cmd did you use and what was the output/error msg? Please use the code tags, its easier to read. |
I have the same mount points in both hard disks
and I am trying to copy all mount points from the PC Hard to the external Hard disk as following example in specific mount point: [root@localhost backup]cp -r /backup/* . But error appear to me ( No space left on devise ) Thanks & Regards,, |
You need to be more specific (actual names) about which disk you are using, as you have several connected.
On the PC, /backup is LogVol08, which says 612M used. /media/usbdisk isn't big enough, if that's what you're using. |
Code:
|
The source is:
/dev/mapper/VolGroup00-LogVol08 116G 64G 46G 59% /backup The destination is: /backup mount point under /media/usbdisk1 The both mount points must be 116G because the both hard disks have the same mount points and sizes The size(116G) mentioned for /backup (source) is true The size(4.0K) mentioned for /backup (Destination) is false For more clarifications: The size for the second hard disk (/dev/sdc3) is right (When be alone) But once i connected it to the first hard disk ( the sizes be very small and not correct ) ?? |
Dears,,
I made work arround for this issue. I am trying to copy the data from the source to FAT32 Hard disk then copy them to the destination. But i faced a problem File size limit exceeded message how can avoid this to can go ahead? Thanks,, |
It is a FAT32 filesystem limitation. The only way to avoid is not using FAT32
Post the output of the command fdisk -l (must be root and l is a small L) Quote:

So sdc1 and sdc2 are ~200G and sdc3 is ~88G which adds up. Without knowing how you created the ext3 filesystems
on sdc1 and sdc3 I can not explain the difference in size. If what you say is true that when both are not mounted sdc1 shows the actual size then umount sdc3 and post the output of df -h again for sdc1. In a nutshell it is a design limitation. The max file size is (2^32)-1 bytes. There is tons of information on the web that explains the differences between the many filesystems. |
Ok . . .
But why while trying to copy from the source to the FAT32 Hard disk it can not copy up to 4 G.B ?? How can avoid this? Thanks,, |
I am not sure if you are asking why you can not transfer files < 4GB or > 4GB.
How big are the files you are trying transfer? |
I solved this problem by
editing /etc/security/limits.conf then add the following line: * * fsize unlimited But when trying to transfer the same files to external hard disk ( /media/usbdisk ) Note:External hard disk is FAT32 It gave me File size limit exceeded message How can solve this? |
