Problem counting unique disks/slices

I want to create a unique listing of slices/disks from a large list that will have duplicates. Here is a sample of the input file.

Code:
#array.txt
Disk4:\s93
Disk4:\s93
Disk4:\s94
Disk4:\s95\s96\s97
Disk4:\s93
Disk4:\s95\s96\s103
Disk4:\s93
Disk4:\s93
Disk4:\s95\s96\s105
Disk4:\s93
Disk4:\s95\s96\s105
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s95\s96\s106

I think the following command should give me what I want. It should output the unique disk/slice name in the first column and how many times that disk/slice occurred in the list in the 2nd column.

Code:
cat array.txt | awk 'count[$1]++ END {for (i in count) print i, count[i]}' > array.txt_unique

However, only some of the lines in the output file are correct. Sometimes it seems that it is not matching the disk name and it thinks it is different when in reality it is the same. See my sample output file below.

Code:
#array.txt_unique
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s95\s96\s105
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s93
Disk4:\s95\s96\s103 1
Disk4:\s95\s96\s105 2
Disk4:\s95\s96\s106 1
Disk4:\s95\s96\s97 1
Disk4:\s93 14
Disk4:\s94 1

I also tried removing the colons and back slashes prior to counting the unique slices, but I had the same result. Can someone help me with this?

Thanks in advance,
Jonathan

irsend - basic LIRC program to send infra-red commands SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
