There is something wrong in my computer, and all office files can not be opened!!! Who can give me a hand to repair these word files? Thanks in my heart.

Can you explain your problem? You can not read onli office files? Can you copy some office files and try to open on other computer? Looks like it is virus or trojan.

I have a bunch of 4mm DAT tapes that contain backups from some legacy system, i have set up a server and an old tape drive to read the tapes, problem i have now is i have no idea what they were written in, i have Veritas on a server (i thought a good choice) but no joy there. Is there any software that can determin what program was used to create a backup on a DAT tape? , yours hopin

can you see any of the file backup extensions; not the individual files?

no cant see anything, but i know there…

HELP! I have a raid 1+0 failure and stripe data is gone. I don’t even know where to start to reconstruct. I am running an Asus m2n32-sli Motherboard with 4 drives. TIA

Relax. You should have 100% redundancy. SalvageData has a RAID recovery tool that has had good reports.

More details would be welcome. What does the RAID BIOS say ? Does RAID BIOS detect the array and its members? Have you tried to rebuild the array in RAID BIOS?
