Mount UFS with GNU\/Linux<\/a><\/li>\n

Sometimes it could be necessary to rescue data from a FreeNAS hardisk or other UFS-formatted drives. UFS will not be recognized and mounted on GNU\/Linux or Windows automatically. To read data from these disks on GNU\/Linux some steps are needed to be done. For Microsoft Windows\u00ae third party drivers are available for this purpose.<\/p>\n
To connect a dismounted FreeNAS harddrive to a desktop or notebook computer a USB adapter could be used. There are several available on the market, e.g. from Digitus or trifoo.<\/p>\n
Please note that a slightly damaged harddisk may still work if it is directly connected to a computer via S-ATA or IDE (P-ATA) but it may not work via USB adapter.<\/p>\n
Mount UFS with GNU\/Linux<\/h3>\n
This How-To describes how to mount a UFS-formatted harddisk under GNU\/Linux which was formatted with UFS2 from FreeNAS 0.69.2.<\/p>\n
You need to do the following steps:<\/p>\n
\n
Open a console window<\/li>\n
In the console, type\n
sudo modprobe ufs<\/pre>\n
to load the UFS driver<\/p><\/li>\n
Connect the harddrive with the GNU\/Linux-PC via USB<\/li>\n
Type\n
dmesg | tail<\/pre>\n
in the console window. In the output you will find the name of the device, e.g. sdb1.<\/p><\/li>\n
Create a mount point in your home directory\n
mkdir ~\/ufs<\/pre>\n<\/li>\n
Mount the connected harddisk\n
sudo mount -t ufs -o ufstype=ufs2 \/dev\/sdb1 $HOME\/ufs<\/pre>\n
If this do not work your system may allow read access only. Try one of the following commands<\/p>\n
sudo mount -t ufs -ro ufstype=ufs2 \/dev\/sdb1 $HOME\/ufs\r\nsudo mount -t ufs -o ufstype=ufs2,ro \/dev\/sdb1 $HOME\/ufs<\/pre>\n<\/li>\n
If you used a rather old FreeNAS version you may succeed with \u201cufstype=44bsd<\/span>\u201c.<\/li>\n
The content of the FreeNAS USB-harddisk is now accessible in ~\/ufs<\/span><\/li>\n<\/ol>\n
Mount UFS with Windows<\/h3>\n
To mount UFS1 and UFS2 harddrives in Microsoft Windows\u00ae you can use:<\/p>\n
\n
UFS Explorer<\/a> (Shareware) from SysDevSoftware (Windows XP or higher, GNU\/Linux Debian 6 compatible or higher, Mac OS X 10.7 or higher)<\/li>\n
ufs2tools<\/a> (free of charge, proprietary license), (Windows 2000, XP, Vista, 7, 8)<\/li>\n
NEW<\/strong><\/em>\u00a0<\/span>Linux Reader<\/a>\u00a0\u2013 Freeware from Diskinternals (read-only)<\/span><\/li>\n<\/ul>\n
I have not tested one of these programs yet. So I can not say anything whether these programs are reliable or work as expected.<\/p>\n
Limitations<\/h3>\n
If you used RAID or filesystem encryption on the harddisk in question this how-to will not work unfortunately. But UFS-Explorer from SysDevSoftware should give access to RAID-harddrives with the Raid-Access-Plugin at least.<\/p><\/body>","protected":false},"excerpt":{"rendered":"
