Re: Former Seagate engineer: Company destroyed evidence

["Tomas L. Byrnes" <tomb () byrneit net>]

The evil is the deny, divert, annoy.... in response to well documented
failures.

Who cares how cheap a drive is if it trashes a month of data?

In my experience, over the last 12 months;

2 WD failures, 3 year old drives that have experienced god-awful heavy
duty (the primary ThreatSTOP servers) on power cycles. Raid 10 and Raid
5 on 3Ware, no data loss.

13 Seagate failures (more AS than ES, but 2 ES bricked as well, at the
same time, which is what caused the data loss and corrupted the 1TB RAID
5), totally random, all drives less than a year old. Single spindle,
Raid 0, Raid 10, Raid 5EE; USB/Sata; Sata, Sataraid; Nvidia, Intel,
Adaptec. Nearly a Terabyte of corrupted data, 50GB (approx) data loss.

0 Hitachi (have several in multiple machines).

The Seagates all had to go through multiple RMA cycles until I finally
got 7200.12s, which seem to be stable.

SMART provides no warning, because the problem isn't with the drive or
the drive controller. 

The only indication of impending failure is ever increasing "Aborted
commands" on the SATA interface, because the problem is Seagate has a
lousy (don't know if it's cheap hardware or buggy software, and don't
care which) SATA interface, which has nothing to do with AS or ES, and
everything to do with bad management.

Seagate: Yet another example of how the race to the bottom strategy
ruined yet another once-great American Business (GM, Citigroup, GE, US
Steel, etc.).

Can we PLEASE put pre-teens in charge of US companies instead of Harvard
MBAs?
