I’ve just install SLES SAP everything fine But when I plug my external Storage to USB port, the storage name is showed but I can’t read the content, I try with 2 different storage and still the same All my storage on FAT32. I try using USB Flash drive FAT32 also and can read the content. Any solution for this matter ? thanks ---

Your post confuses me a bit. You state that you cannot read storage connected via the USB and that all your storage is FAT32: > [@tdphanab1](#): > > But when I plug my external Storage to USB port, the storage name is showed but I can’t read the content, I try with 2 different storage and still the same All my storage on FAT32. But then you say that you can read a FAT32 formatted flash drive: > [@tdphanab1](#): > > I try using USB Flash drive FAT32 also and can read the content. So you both cannot and can read FAT32 formatted devices attached via USB. You refer to what you can’t read as ‘Storage’ and what you can read as ‘USB Flash drive’ which makes me think they are different. What exactly is ‘Storage’ in this context? As soon as you plug in the ‘Storage’ that you cannot read connected can you run ```auto # dmesg | tail -20 $ mount $ lsmod | grep fat $ lsmod | grep usb_storage ``` and post the output. Wrap the output in CODE tags to make it readable. (Use the # button in the toolbar.) ---

Can you mount it manually as root? E.g. ` $ mkdir /mnt/tmp $ mount /dev/sdc1 /mnt/tmp` Have you got any other Linux machines you could try plugging it in to to see if they automatically mount it? ---

I have old Ubuntu 8 system never have a problem with external usb device, I’ve this fujitsu also on ubuntu and everything fine. On SLES SAP, i find 1 hitachi 500gb usb external HDD can be mount normaly but when I copy a file to the SLES it converted as lowercase, the original file name in uppercase. Now i have to use winscp or FTP to copy file to/from SLES really annoying ---

What file system is the Hitachi formatted with? FAT32 and NTFS are case insensitive but case preserving. This could account for the change in case you describe. Can’t think of any more advice on why the Fujitsu doesn’t mount automatically. ---
