Jag har LinuxMint Mate 20.2

När jag går in på en 2,1 TB så ser det ut så här:

Detta är ju bara en hd men varför finns det fler.
4D97-9F072
Dom andra med samma namn verkar ju vara låsta för man får detta meddelande om jag försöker öppna en annan:

Under "/media" kan det ibland finnas kvar rester av tidigare monteringar. Det som finns kvar där då, är bara själva monteringspunkten. Det ligger ingenting under den, det är bara en tom mapp.

Filer/mappar under "/media" har dessutom ofta en ACL ("access control list") som tillägg till de vanliga filrättigheterna. Normalt sett ägs monteringspunkten av "root" och vanliga användare har inga rättigheter där, vilket de (t.ex han som stoppat i minnet) däremot får via ACL.

Förmodligen är de övriga mapparna/monteringspukterna rester från tidigare monteringar...

Tack för hjälpen.
Det finns väl inget att göra åt det då förstår jag.

Njo.
Ligger det skräp under /media borde man kunna radera skräpet.

Första gången jag hör talas om ACL i Linux, så jag är inte rätt person att svara.
Men en snabb googling säger att man kan skriva
mount | grep acl
för att se om acl används.

Annars kan du testa bara mount och se om de där konstiga mapparna dyker up, som 4D97-9F071.

Fick detta av dina kommandon:

Du kan skriva:för de olika monteringspunkterna också, så ser du om de har någon acl...
