Bry,

Mam dysk:

=== START OF INFORMATION SECTION ===
Model Family:     Toshiba MG08ACA... Enterprise Capacity HDD
Device Model:     TOSHIBA MG08ACA16TA
Firmware Version: 0103
Sector Size:      4096 bytes logical/physical
Device is:        In smartctl database 7.3/5577
ATA Version is:   ACS-3 T13/2161-D revision 5
SATA Version is:  SATA 3.3, 6.0 Gb/s (current: 6.0 Gb/s)
SMART support is: Available - device has SMART capability.
SMART support is: Enabled
AAM feature is:   Unavailable
APM level is:     128 (minimum power consumption without standby)
Rd look-ahead is: Enabled
Write cache is:   Enabled
DSN feature is:   Unavailable
ATA Security is:  Disabled, NOT FROZEN [SEC1]

Jest w obudowie USB, ale widoczny w systemie normalnie (i także s.m.a.r.t):

Dysk /dev/sdd: 14,55 TiB, bajtów: 16000900661248, sektorów: 3906469888
Disk model: MG08ACA16TA
Jednostki: sektorów, czyli 1 * 4096 = 4096 bajtów
Rozmiar sektora (logiczny/fizyczny) w bajtach: 4096 / 4096
Rozmiar we/wy (minimalny/optymalny) w bajtach: 32768 / 32768

I ten dysk się wyłącza po paru minutach nieużywania. Chciałbym go zniechęcić do usypiania, niech się buja non stop.
Wygooglowałem taki wpis na jakimś forum:

"Disk sleep can be disabled with 'hdparm -B 255 -S 0 <device>' if you drive allows to disable APM completely or with 
'hdparm -B 254 -S 0' if it doesn't. md raid will not access member disks unless it actually needs to read or write data. 
Are you sure that disk is indeed going to sleep, does SMART start/stop count grow? not doing some internal testing or 
SMR-related rearranging (I am not implying that this is an SMR drive - don't know this)."

I pytanie czy to bezpieczne? Czy może coś pójść nie tak? Nie chcę uszkodzić dysku, bo tani nie był.
Jeśli to nie zadziała jaki inny sposób jest możliwy?
