When I remove it is removed... somehow... but It looks like there is a ghost disk added (still with the kernelname sdb1) but not accessible (of couse.. I hold the disk in my hand...). replugging the same device doesn't fix the problem and does not work. here's a short version of the above dmsg: ####################################################################### ####################################################################### ###########1) Hotpluging a disk for the first time##################### ####################################################################### ####################################################################### Oct 30 02:33:09 freax [ 951.885385] ata2: exception Emask 0x10 SAct 0x0 SErr 0x10000 action 0x2 frozen Oct 30 02:33:09 freax [ 951.885390] ata2: irq_stat 0x00400000, PHY RDY changed Oct 30 02:33:09 freax [ 951.885396] ata2: hard resetting port Oct 30 02:33:09 freax [ 952.607499] ata2: SATA link down (SStatus 0 SControl . . .
