Data is data. It's not analogue tape. So no.
Whoever informed you your sessions would not be readable is wrong, and you should probably stop listening to their advice re computers and pro tools. PC pro tools sessions are just about always readable by macs, assuming the drive they're on is readable (and Macs can read just about any PC formatted drive, they just can't write to NTFS ones). As has been pointed out, PCs can have issues with older PT sessions from Macs, but only under specific circumstances - and it won't affect you as you're going the other way.
FWIW you should have a backup of all your sessions anyway. Do that NOW before anything else.
If your glyph drive is empty, you can format it to FAT32 and both PC and Mac will be able to read and write to it. If you're then going to use it for audio work, I'd copy the data onto the mac and reformat for GUID for the mac. If you've already got data on the glyph, just get a cheap USB drive as suggested.
