Q. I am interested in a ballpark price to recover data from 22 potentially water/heat damaged LTO-2 backup tapes
We would recommend you to bring the tapes to one our labs for free evaluation. We will be able to give you the exact estimate / cost for recovering the data from the tapes only after the free evaluation of the media. However, tape recovery is a time consuming process and requires expertise skills.
Nevertheless, whatever may be the cause of data loss from tape cartridge, Disk Doctors has years of experience in recovering data from them.
