Default Recommend data recovery company?

As an aside to your failed drive issue, perhaps you might want to
consider running drive health monitors on your other computers. I use
HDD Sentinel but there are other choices. Some drives include
Calibration Retry Count (attribute 0B hex or 11 decimal) in their SMART
data. It measures the number of retries to calibrate a drive which can
indicate problems with the motor, bearings, or power supply of the
drive. My Western Digital drive do but no my Seagate drive (and it's
not relevant to the SSD drive).

Apparently this attribute is not rated as critical to the health of the
disk. Usually the Current Pending [Reallocation] Sector Count (number
of unstable sectors waiting to get remapped and copied to reserve
sectors) is more critical in measuring a drive's health. In HDD
Sentinel, both attributes are enabled (included) to affect its measure
of a drive's health but I don't know the weighting they give to each.

Here's the list of SMART attributes that HDD Sentinel will monitor:

SMART really isn't that smart. A drive with an A-rating regarding its
health could immediately fail. A drive with an F-rating could continue
running for years. SMART is just trying to report some behaviors of the
drive and extrapolate might they might indicate. SMART is failure
prediction, not proof of imminent failure. A SMART health monitor might
say "green" but the drive still fails. However, if the monitor says
"red" then it's time to do backups (which should be regularly scheduled
for other than just hardware failure), move data, or clone the drive.
