My friend recently asked me to recover data from his sata ssd  TeamGroup
2.5" drive. It was showing up randomly disappearing, and after some time it
did not reapond at all. I thought I have to desolder the NAND chips and
read them in memory programmer, but first run of reballing made it back to
life again and simple dd rescued data :-)

If the problem persist with the drive on another OS and/or computer and/or
external sata reader that may indicate problem with the disk.

Cables are also the problem. Even on black 6G cable and 6G controller some
6G capable hdd drives work at 3G.

Also one WD Green HDD that was not used for years started working
incredibly slow, no SMART problems were reported, so I did a backup, and
right after that dd it with zero with no problem but dd from /dev/random
was almost impossible to write. In the end SMART started reporting errors
but that would be too late to rescue data by then.
