Drive identifiers scrambled

Hi guys, I added a new hard drive to my system and when I booted - the drive identifiers are all mixed up:

/dev/sdb2: LABEL="swap" UUID="28a60923-5cf3-4903-9eb1-a72b34ef8188" TYPE="swap" PARTLABEL="swap" PARTUUID="dd57062a-1ee7-4902-9c7a-f5ca9501a4a3" /dev/sdb3: LABEL="root" UUID="6e95d498-965a-4148-af43-28b402b13f23" TYPE="ext4" PARTLABEL="root" PARTUUID="2954b1bf-555b-4a66-ae92-54d56ef99ca0" /dev/sdb4: LABEL="home" UUID="db3e8f82-3777-401a-ae3b-789781b52e5c" TYPE="ext4" PARTUUID="d6327c16-1d2f-4d46-bfa7-0c9036668e09" /dev/sdc1: LABEL="BACKUP" UUID="c2936b5d-c10a-4504-a255-d60b9c73cbe5" TYPE="ext4" PARTUUID="185110a0-cb27-4372-b4de-181b7e9aa3a1" /dev/zram0: LABEL="zram0" UUID="751e7491-e01b-4684-9eb2-6240db8a9369" TYPE="swap" /dev/zram1: LABEL="zram1" UUID="1525e4e1-8c8a-40f3-8f15-7f902a3ebab5" TYPE="swap" /dev/zram2: LABEL="zram2" UUID="66470a1e-e0b1-48e2-ac19-f7b93a2b49e2" TYPE="swap" /dev/zram3: LABEL="zram3" UUID="c2eb9dab-1126-4009-839c-59afa3f69ebf" TYPE="swap" /dev/zram4: LABEL="zram4" UUID="db6e6697-1f60-4737-b3c0-85fb8567c493" TYPE="swap" /dev/zram5: LABEL="zram5" UUID="c3b54d02-ad28-499a-be04-5dd3ef20877b" TYPE="swap" /dev/sda1: LABEL="Removable HDD" UUID="1888c55e-e2b0-4e83-a8f6-a93695d60d7b" TYPE="ext4" PARTUUID="0ef8dbb9-c326-49e2-9f9e-e766b0e6d350" ]

/dev/sda should be my disk with the root and home partitions on it (now sdb)
/dev/sdb should be my backup disk (now sdc)
and /dev/sdc should be the new disk (now sda)

can someone help me to correct this?

Many thanks

That’s not a Linux issue it a IDE/SATA position issue, you just need to move the drive connectors around.
IDE drives are always first:
IDE 1 and 2 = sda and sdb
IDE 3 and 4 = sdc and sdd

Sata are then numbered in order, sata 1,2,3,4, etc.
