Záloha metadat/Kychot/SAMSUNG Portable SSD T5 1TB/2020-10-11

2020-10-11 neděle – problém

Disk jsem rozdělil na dvě stejně velké partitions pod Windows 10 (viz výše)
První partitions jsem naformátoval na NTFS pod Windows (viz výše)
Nacpal jsem na ní spoustu dat z Windows, které mi tam překážely
Pak jsem disk používal pod Ubuntu – stále jen s touto jednou partition, nacpal jsem tam další hromadu dat
Disk jsem měl stále připojený/přimontovaný přes USB-C kabel
Před chvílí jsem zjistil, že ten disk není připojený, kontrolní LEDka nesvítila, ale v utilitě disk nebyl vidět
Tak jsem jej odpojil a znova připojil, a zase nic
Tak jsem si při připojení pustil:

tail -f /var/log/kern.log

Koukám, co se předtím dělo:

To jsem šel ve 4 ráno spát.

Stroj jsem probudil zase po ránu:

Kolem 9:30 jsem přes JitSi sledoval bohoslužby. Netopil jsem, bylo tu asi 17 °C

Oct 11 09:42:38 x2 kernel: [141366.191980] CPU1: Package temperature/speed normal

Pak jsem ještě paralelně k JitSi sledoval bohoslužby na FB
Pak najednou:

Pak se to ještě střídavě opakovalo:

Pak dlouho nic, až nakonec:

Na SSD svítí modrá ledka, ale automaticky se nepřipojí. Utilita Disk ho ani nevidí.
