Your new 200GB 7200 RPM disk must be now your Primary Hard Drive for your OS. This disk must be fastest and better than any of the old ones.
You can clone your original Disk to the new 7200RPm disk and put the old one in the External BOX.
You can now use your external and 2nd disk for backup purposes.
The ideal setup for your systems will be:
Partition1: C for OS and software, 15 GB
Partition2: the rest. Here you will put your PST, email, docs, etc
Your old 40GB disk can be installed in the usb2 external box. You can use this box for Backing up your c (a clone) and docs (your d drive).
You can sell or keep your old 20GB drive.
let me know if you have any doubts or need help in order to make the required changes.
WinXp Pro P3 600mb 512 RAM
I obtained a Maxtor 200gb 7200 ultra ATA/133 hard drive and an USB 2.0 hard drive kit from ADS model #USBSX-835. Currently have 2 HD's, main C: has 40gb Maxtor,25gb used, D=old HD 20 gb for backups etc.
My question is whether I should use the new HD to replace the current HD or use it as an external backup media ?
Please note that I have never formatted and or replaced a HD before. Therefore I would appreciate all the kind help from the experts on this forum. By the way I have one other computer Win Xp Home P4 3gb Sony Vaio 512mb RAM. I am interested in updating the older puter. Will I be able to install the new HD 200gb on the P3 XP Pro with limitations I read somewhere re HDs over 137gbs or use this an external HD for backups etc.?
