Looks like the specification is 32x CD read, 8x DVD read,
8x CD-R write and
4x CD-RW (re)write
The 4x lowest speed of "High speed" media is not conpatible with the 4x speed of older drives, which only support "1-4x" at (up to) 4x and unspecified or 2x media at 2x.
Due to the construction of RW media, you do not have a free range of speeds, as there are 3 different media types.
1. Original (2x, later 1-4x)
2. HS (High Speed) - nominally 4-10x, but also 4-8x, 4-12x, and in some drives, overspeed to 16x is possible -
Only usable in drives with the "High Speed" or "Ultra Speed" designations - High speed drives are also not certain to support the original low speed media.
3. US (Ultra speed) - speeds of 16x to 24x (and later 32x)
So low speed RW is required for that drive, and reliability / compatibility of CD-RW is vastly inferior to CD-R.
- Just checked XSCT, no low speed RW

- Bigpockets - 100 CD-RW 4x for £9.49 (plus P&P) - it's the right TYPE of media for that drive, but given the nightmares I've had with CD-RW, I can't assure you that it would actually WORK in that drive.

The only other CD-RW 4x they have, 5 cased for £3.17
If you won't be too cross at losing £9.49 + P&P if the drive doesn't like the media (and it's happened to me with various media on two drives!), then I'd say you have to chance the 100 pack "when it's gone, it's gone" - if you need low speed RW, you have to lay in supplies NOW, as it's certain to go from low price clearance to high priced rare, if it can be found at all.
I'll repeat the warning though, it's the right TYPE for the drive, but it might not be any good in it - hopefully the Samsung is less finicky than my drives.
