UFS explorer to recover data!!!

GrAfiX · 10-12-2007, 07:13 AM

I have a 4100 that crapped the bed... So I got this program UFS explorer it actually reads SnapOS drives.

I just had to put the drives in a Intel Computer and it actually can pull data off the drive.

It's working ok, If I do the RAW file recover format I am actually able to recover files.. However it's not pulling the Directory structure because I cannot locate the Master Boot Record and the File system data.... I think I may have some settings wrong when rebuilding the array with the program.

Here are all the settings
Raid Mode - Raid 5 (obvously)
Stripe Size- Only after I changed to 64kb could I recover files...
Raid Parity Distribution - Left Symmetric (backward-dynamic) I assume this is right also since it is rebuilding the data.
Parity Length (stripes) - 1 (dunno if this is right) it's a txt box to enter a number no choice.

Now these settings I think what I am missing to pull the MBR and FS off the drive.
Controller- Reserved Sector Information:
Reserved from disk start: set to 0 it's a text box to enter a number
Reserved at disk end (for spanned RAID): set to 0 it's also a text box.

I'm happy to say all hope is not lost on my hosed system, I just need any and all info to help me. Worst case senario I look at each important file and rename but if I could actually find the FS and MBR it would save a lot of time with my 270 gigs worth of data.

the url to the program is http://www.ufsexplorer.com/ and only costs $69 bucks... Way better than the $9000 I got quoted for Disaster recovery where they will probably do the same thing.

Here is a screen shot of the program and all the settings so you can see also.

All your getting is a raw recovery, UFS explorer is not reading anything other than file headers. And u could have used "get data back", "ontrack easy recovery", and any other utility that will do what is called a raw recovery.

There is no way that ufs explorer can actually read the snap os because the superblock magic number that ufs explorer identifies ufs file systems as is not located in the same place on the snap and is not the same.

So what you are going to end up with is a recovery with no file names other than 1.jpg, 2.jpg, 3.jpg. This is ok if you know exactly which type of file you need, and if you only need a hand full or so.

And if it is missing the header for a particular file, then you won't see that file recovered.

I have several dead snap 1100 servers (bad electronics; severe electrical storm) and was able to UFS explorer to read the drives in their and pull all the data. Once you figure out the interface it's really easy.

At first, I thought it was another tool that didn't work because it was displaying these messages that the drives were corrupted. After RTM and clicking on th partition option it found everything and was easy to use.

I plugged it into a Windows XP box and it just worked.

It was well worth the $70.

I have read alot of messages in the forum here and many could be solved with this tool.
