Last week I purchased a 1 TB external drive for $90. I also got a 320 GB internal laptop drive (2.5" SATA) for $60. In both cases I could have got cheaper drives if I'd been willing to order them over the internet (from reputable vendors, not ebay or fly-by-night thieves) rather than buying them locally so that I could get hold of them immediately. The 1 TB external drive replaced a 320 GB external drive which cost over $200 when I bought it. The price of storage is plummeting. if you need drive space, buy another drive. > > My attempts to compress them were doomed to > failure because I do not have the smarts to handle > the various road blocks from the error messages > that pop up when I attempt to compress > the TM file, by using "Compress Archive". > (from the "File" menu) The TM files are already compressed.

Good point. (And given the history of TC, the image may be even sparser than intended!) -- iMac (27", 3.06 GHz Intel Core 2 Duo, 4 GB RAM, 1 TB HDD) � OS X (10.6.2) |
