255821	2004-07-27 11:13:00	I am interested in purchasing a USB2 external hard drive (80 or 120Gb) to facilitate transfer of large chunks of data from one address to another but I am getting conflicting stories about installation. Some gurus tell me that I just plug and play but others say it is necessary to go inside the case and change jumpers on the BIOS. Both computers use WinXP and I would be physically carrying the EHD from one address to the other. Thanks.	wjohn (2330)
255822	2004-07-27 11:29:00	assuming you have usb already working then there is no need to open the case or access the bios.	tweak'e (174)
255823	2004-07-27 11:30:00	Windows XP will support the USB drive with inbuilt drivers. Drivers are needed for MS OSs prior to Win98SE. No changes to any jumpers will be required.	JohnD (509)

255826	2004-07-27 12:03:00	just wondering about these external usb 2.0 drives ; some associates are setting up a server:client network - dual processor / 1g ecc ram / RAID 5 scsi setup running MS Server 2003 , 1000 VA UPS etc all looks great , but the IT guy has recomended a tape backup system - [Exabyte VXA 2 using Veritas software- 5 tapes incl ] for about $4000 - now I've heard tape can be a little unreliable and for the price they could get 10+ external USB2 Maxtor HDD , or 5 and save $2000 or so , or spend the difference on TFT screens etc . Are tapes really better ? It's a business and backup/ storage off site is extremely impt . Any thoughts / experience would be much appreciated :)	KatiMike (242)
255827	2004-07-28 04:21:00	The Exabyte tape drive is a professional archiving system . The ¼" tape systems (and probably their "Travan" descendents were highly unreliable, an obvious consequence of the ridiculously high bit density --- something like 18000 bpi . The industry standard ½" tapes were never recorded at more than 1600 bpi . That was reliable . The drives cost from $18000 up . QIC drives cost about $100-$200 . The idea of using removable disk drives for archiving is appealing, not just for cost . But I don't think it would be considered "archiving" . For a start, have a look at how courier drivers handle parcels . :D The transport to and from the off site storage might be a bit of a lottery . Tapes can handle a fair amount of rough handling . Disk drives can't . And you don't know if damage has occurred until you need the data . A tape damaged enough to be unreadable is likely to be noticed .	Graham L (2)
255828	2004-07-28 09:14:00	I know of a guy who had 4x external HDD's and ran the backups by alternating sets of two each day. The HDD's were set to "mirror" so there was no chance of failure...	Chilling_Silence (9)
255829	2004-07-28 09:51:00	Hi Robsonde What is the essential difference between the 3.5" case and the 2.5" case (6768) please ? Probably at least a difference in capacity ? But anything else too ? Misty	Misty (368)
255830	2004-07-28 11:27:00	The difference between the 2.5" case and the 3.5" case is, naturally, 1" Laptop/Notebook HDD's are 2.5", and quite expensive relative to 3.5" Desktop PC drives. A 3.5" drive will not fit in a 2.5" case, using common logic. But your question may have had another meaning perhaps, and not the basic physical difference? No idea why the price difference, would have expected it to be the other way around, if any. Perhaps though its due to the lower power requirements of the 2.5" drive, as no external power supply is needed or included?	godfather (25)
