Thanks in advance for your help.

You can find Tools, Recovery, Diagnostic, Emergency useful to download;

(R)ecovery (I)s (P)ossible <- RIP Slackware® Linux rescue system
UBCD Ultimate Boot CD <- 'UBCD allows users to run floppy-based diagnostic tools from most CDROM drives on Intel-compatible machines, no operating system required. The cd includes many diagnostic utilities.'
PHLAK <- Security, LiveCD
TRK <- Trinity Rescue Kit + 'Aims specifically at recovery and repair operations on Windows machines, but is equally usable for Linux recovery issues.'
Knoppix STD 0.1 <- Security & Recovery Tool + Knoppix STD description
SystemRescueCd <- 'is a Linux system on a bootable CD-ROM for repairing your system and recovering your data after a crash. It aims to provide an easy way to carry out admin tasks on your computer, such as creating and editing the partitions of the hard disk. It contains a lot of system utilities (parted, partimage, fstools, ...) and basic tools (editors, midnight commander, network tools).' + 'Online-Manual
TestDisk <- 'tool to check and undelete partition, supports reiserfs, ntfs, fat32, ext2/3 and others' + Above Livecds contain TestDisk + TestDisk Wikipedia + wiki + Data Recovery using TestDisk
PhotoRec, Digital Picture & File Recovery <- 'PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from Hard Disks and CDRom and lost pictures (thus, its 'Photo Recovery' name) from digital camera memory. PhotoRec ignores the filesystem and goes after the underlying data, so it will still work even if your media's filesystem has been severely damaged or re-formatted'+ After Using PhotoRec + PhotoRec Wiki

-- Memory:
memtest86 <- 'Memtest-86 is a very thorough stand-alone memory test for x86 and Pentium systems (and compatibles). It currently does 11 tests to fully determine whether you have faulty RAM or not.'
memtest86+ <- 'memory tester which is based on memtest86 v3.0, and provides an up-to-date version of this useful tool, which aims to be as reliable as the original. It has been fixed to work on AMD64 systems, and also properly detects all current CPUs and motherboard chipsets. The project supports ECC polling for AMD64, i875P, and E7205, and displays some useful settings for the most popular chipsets'

I keep several of the diagnostic disk on hand for when diagnosing issues with a system. UBCD & SystemRescueCD are very useful and you will find memtest86+ on both.

Hope this helps.
